range bars binary options

After being in beta since the last year I have finally released the official version of HexEdit The beta version worked fine so I have not been in too much of a hurry to release it. There were a few minor bugs fixes though. The BCG library is an excellent MFC extension library so I do not regret using it. To build HexEdit you only need Visual Studio, plus some open source code and libraries most of which came from right here on CodeProject. You can use the program or any of the source code for whatever purpose you see fit as long as you abide by the relatively unrestrictive license requirements see below or any specific requirements for any of the included 3rd party code.

I wrote HexEdit in as it was something I needed in my work and the hex editors available at the time were poor. HexEdit was always designed to be simple to use and familiar to users of Windows software such as MS Word and Visual Studio.

In fact it borrowed many ideas from these and other common Windows programs. In JanuaryI released HexEdit with source code to the public and got a lot of positive feedback. Some people even emailed asking how to pay for it!

Some of the acclaimed features of the first version were unlimited undo everything not just file changeseditable file size not limited to memory size, EBCDIC support, simple but fast searches and file compares, keystroke macros The most useful was the floating "Properties" window which could show all sorts of interesting stuff about the byte s at the current cursor position in the active file. At that time I had a huge list of things that I wanted to add - some were user suggestions but mainly they were my own ideas.

I decided to make a shareware version, so that I would have some encouragement to continue adding features and so that I could justify the large amount of time I spent on it. The only ones remaining from that list are a better file compare utility and a memory editor. I have actually implemented both of these in the past but they were not of sufficiently high quality to be added to the released version.

In I released HexEdit shareware which used the very cool BCG library. Unfortunately, using this commercial library meant people could range longer easily use the source code for the free version of HexEdit. I have always made earlier versions about years behind the shareware version available for free with source code on request. In the intervening years I have added most of the the abovementioned features and many more but my TODO list is longer than ever!

The display engine was rewritten in this version which allowed new features like change tracking, "stacked" display mode, sector display, etc. This also improved display speed, especially for long lines. The max line length was increased to 32, In this version of HexEdit I converted the code from using BCG to MFC9. I started this early in and it took longer than expected.

Part of the reason is that I have converted the modeless dialogs to use the new docking system - the fancy one like in Visual Studio where you can dock several windows on top of each other and tabs are automatically added.

The dockable windows are the Properties dialog, Find dialog, Calculator, Bookmarks dialog and Explorer window. HexEdit has very many useful features which I can only just touch on here.

Here I will just explain the general philosophies of the design of HexEdit and introduce a few features as examples. One thing to remember is that if you need a feature it might already be there.

I often get emails asking for a specific feature which is already present Try to find it in the help. Another thing to remember is that if you often find yourself spending a lot of time doing a tedious or repetitive task then there is probably a feature in HexEdit to save you time.

Another type of email I get is from users saying they found a useful feature that they did not even know they needed but has since saved them a lot of time. An overriding principle has been to keep the user interface as simple and uncluttered as possible. It is a common failing of other hex editors that they assume an advanced user who uses the program every day with bulging menus full of rarely used features.

The idea is that the user interface is not overwhelming. An infrequent user as users of hex editors often are can use the program without constantly referring to the help. Of course, if you need it there is lots of help available. The mark is a simple facility that allows you to mark a position in a file and return to it later.

It is also useful in many other areas such as keystroke macros I think I got this idea from a text editor I binary pEdit, Epsilon or Emacs. One problem with keeping the user interface simple is range some of the more powerful features may not be obvious. Whenever appropriate I have tried to emulate the common behavior of other Windows programs.

For example, many hex editors use the Tab key to switch between the hex and character areas. There is also a de facto standard for the behavior of cursor keys, mouse, etc as seen in many editors. HexEdit often has similar behavior to common Microsoft programs like Word and Visual Studio. Also, many users are already familiar with these programs so they should feel right at home.

Here are some examples: Bookmarks are based on the bookmarks of Developer Studio the precursor to Visual Studiobut with improvements. Whenever you perform a search HexEdit automatically does a background search throughout the rest of the file and all other open files in a background thread.

This will not interfere with your editing, since the background search runs in a low-priority thread. When the background search is finished you can immediately see all occurrences highlighted in a special color. The background search will normally be completed before you even notice unless you are working with very large files - but while it is running the progress is displayed in the background search occurrences pane.

When finished a count of the occurrences is shown in the status bar pane. HexEdit has always easily edited files of any size without any extra effort on the part of the user. Before HexEdit most hex editors could not edit files bigger than they could load into memory. Since then many have copied how HexEdit works. There have been several improvements to HexEdit since the first version so that you can now insert huge files into other files, etc All operations on the selection including compression, encryption, checksums, CRCs, etc work with a selection length of any size.

Progress is shown in the status bar and you can, of course, abort the operation by pressing the Spacebar or Escape key. The ability to configure HexEdit has always been important. The user should be able to decide how they want to work. In HexEdit I incorporated the BCG library which among many other things allowed for complete customization of the toolbars, keyboard, menus including many context menusetc.

Many programs show a small usually yellow tip window when you hold the mouse over an item of interest. HexEdit takes this further with Info Tips. In a binary editor what you find interesting about some of the bytes of a file may not be what someone else does, and can change for different circumstances.

Info Tips allow you to create one or more tips based on several predefined values addresses, offsets, file data etc and using C-like expressions and with many formatting options.

You can perform calculations on addresses. For example, is the offset within the current sector divisible by three? You can examine the data at the mouse position using dozens of different formats floating point, date etc.

For example, display "YES" or "NO" depending on whether the 6th bit is on or off, or check whether the current IBM floating point value is negative. Since HexEdit allows you to work with any type of file you can customize this filter list any way you like. You can add or delete filters in the Options dialog on the "File Type Filters" page. Since you may work with different types of files at different times you can turn the filters on and off without deleting them using the checkboxes.

Moreover the same filter list is available in the "HexEdit Explorer" window. This allows you to filter the list of files that you see. This is another example of integration between the features see below Not only is the user-interface compatible with what you are used to in other programs, HexEdit also attempts to work well with other software.

When using the clipboard HexEdit supports text data and binary data. The binary data format is exactly the same as the format used by the Visual Studio hex editor.

In fact the integer and floating point options are compatible with the CSV comma-separated values formats used by many programs such as spreadsheets. These formats are used by many device such a EPROM programmers. HexEdit includes many nice features such as support for noncontiguous records. You can also import and export using hex text, where each byte is stored as 2 hex digits in ASCII. For CSV format use the Copy As C Source dialog see above. One thing about HexEdit that many users have commented on is the simple tool set that provides the flexibility to easily perform a wide variety of tasks.

On the Edit toolbar are two simple drop-down lists that provide a large number of facilities. These are the hex and decimal jump tools. There primary purpose is to allow you to binary in an address to immediately jump to it. The drop-down lists provide a history of the last addresses jumped to.

But they also do a lot more. First as you move the cursor through the file they are updated with the current address. To remember an address by adding it to the history it is simply a matter of clicking in the tool and pressing Enter.

A further feature is that as you type a value into one tool, the corresponding value is shown in the other tool. This allows quick and easy conversion between hex and decimal. Finally, you can evaluate any expression in these tools including assigning to variables that are stored between sessions.

See below for more on expressions in HexEdit. As you type an expression into a jump tool the result is displayed in other visible jump tools. You can have any number of jump tools visible by customizing the toolbars. Sometimes I get a request for a feature where I just have to say "no", because it is just too special to be of general use.

Even then, most of the time I can simply point out how the feature can be accomplished by using existing an existing tool or a combination of tools. One of the most flexible capabilities is provided by keystroke macros. Of particular use are the calculator buttons which are all recorded and stored in keystroke macros.

Many users do not realize that macros can work between files so you can do things like copy a bit of a file and paste it into a temporary file for further manipulation. Macros can also call other macros. This is demonstrated in the "AllChars" macros distributed with HexEdit which creates a new file and fills it with all different byte values. Part of the flexibility of HexEdit is that there are many simple tools that have been designed to work together.

An example, mentioned above, is the range the calculator buttons can be used in keystroke macros. Here are bars more examples: Color schemes are useful for setting up the colors used for other features such as bookmarks, search occurrences, change tracking etc.

One very useful feature of color schemes is the ability to display colors for ranges of byte values. For example, in the default ASCII color scheme normal text is blue while control characters are red, except for the control characters that are normally found in text files tab, CR, etc which are green.

The use of color schemes is also crucial in combination with the aerial view feature. If you have particular byte value s that you are interested in you can create a color scheme to show up the value or range of values in the aerial view. If you have a file format which you know nothing about you can use the "rainbow" color scheme to get an idea of the different byte values in the file - this often immediately shows up areas of interest.

Searches are another area where the various tools work well together. For example, the history list of the search tool edit toolbar is integrated with the search histories in the different pages of the Find dialog. The Find dialog also supports aligned searches which are a very useful and powerful feature. The alignment can be relative to the mark see above. First, as you move the cursor caret in the file the display is updated to show information about the current byte s.

There are several pages so you can see information about integers, floating point numbers, dates, etc. Since its introduction the template system has easily been the feature that has attracted the most interest.

I have been told that people have spent weeks and even months to write a program to edit a particular file format. With expressions you can analyze just about any type of field from a file and use that to control the evaluation of the template. Expressions can be used to control branching IF and SWITCH and loops FOR with counter or with terminating condition. In addition, JUMPs allows out-of-order processing such a "header" at end of file.

STRUCTs can be self-referential so you can model recursive data structures. An example of the power of templates is that they can be used to look into a filesystem when combined with the disk editor to display information and the data from say, a deleted file. The parser supports all parts of the C standard preprocessor, unions, bit-fields, etc and even some extra things like pragma pack. Binary editors are the domain of programmers so many of the features are aimed squarely at programmers.

For example, expressions as used in templates, calculator, jump tools etc are based on expressions from the C-language.

Similarly formatting as in templates, Info Tips etc are based on printf format specifiers or strftime formats for dates. Zlib is the de facto standard for data compression. It provides excellent compression, there is an open source library in C and it is unencumbered by patents or any others restrictions. Moreover, many compilers and run-time environments provide it by default e. Net, It is used in many file formats and communication protocols - for example, it is used in. Zip files also support other algorithms but nowadays files are generally compressed with "deflate" as it is the best.

Over the years I have worked on several projects that used zlib. To assist testing and debuging I added zlib compression with support for every one of its options. Previously, I had to create a small test program to test such things as the best strategy to use for my data or how often to write full-flush points.

Now I can just load my data into HexEdit to test the different zlib options. To build HexEdit you need to download one or two of the above zip files. You will probably need the extras zip file, which contains the FreeImage and boost files required to build the project. If you have FreeImage and Boost installed you may not need these.

It also contains some image "source" files PDN formathelp files, and the Installer source files. There are separate project files for different versions of VS.

When installing VS you need to have installed the C language and MFC DLLs. I have been told that you cannot use the free Visual Studio Express editions as they do not include MFC.

Depending on what you want to do you may need some other free tools. Hopefully after downloading and unzipping the project and extras filesall you need to do is open the project for the version of Visual Studio you are using, tell the compiler where to find the Boost and FreeImage headers and library, and build HexEdit. First you need to have the MFC Feature Pack installed since this includes the version of MFC where MS added the BCG code.

It was not quite ready for the release of VS so was put in a separate feature pack. If you have VS but not the feature pack you can download it here. To set up VS to find the FreeImage and Boost files you need to add to the Include files and Library files locations. The Include files and Library files locations for FreeImage and Boost should already be set up in the correct sub-directory. When I started work on the template system I was keen to make the format for template files as open as possible, and also use a text not binary format in the hope that others might also support the format.

I had just been reading about XML and this seemed the ideal format for template files. Moreover, using an appropriate DTD would save me a lot of work in parsing any text file to ensure it conforms to the correct format. If you are using W2K Windows you will need to have SP4 installed or IE6. Of course, you should be careful not to overwrite a new version of the DLL with the version supplied If you have a newer version of FreeImage installed then HexEdit should be compatible but please contact me if there are any problems.

Boost is huge so I have not included all of it, but I have included all the headers you need to build HexEdit in the boost subdirectory. Alternatively you can download and install the full Boost library recommended and set up an include location to point to it. Another optional step is to have replace the default HexEdit icon with one that looks better on Vista and Windows 7.

As Visual Studio does not properly handle icons like these I used a 3rd party commercial icon editor see Real World Icon Editor to create this file. This version of HexEdit uses the open source WIX installer. I chose WIX as it was the only free installer that produced a. MSI file MicroSoft Installer file and had the features I wanted. Though very flexible it is difficult to use unless you are very familiar with how the Windows Installer works.

Of course, you have to build the release configuration of HexEdit. You also need merge modules for the CRT C run-time and MFC DLLs. If you did not install the merge modules when you installed Visual Studio you will need to do that now.

Some areas of the design of the software are poor for various reasons but other parts are excellent. The overall design conforms to MFC design patterns including the classic MFC Document-View model which is similar to MVC, but combining the view and controller. The classes CHexEditView and CHexEditDoc provide the core of HexEdit, by implementing the view and document of the Document-View model. A core part is the ability to handle huge files keeping track of changes in memory and temporary disk files.

There are many comments in the code including detailed design explanations at the start of some source files. Apart from that, the best way I can think to give an overview of the code is to explain the contents of each of the files. I will just list the header.

Generally each header file contains one class and perhaps related structs or classes. There are exceptions as noted. In fact many people have emailed and asked for permission to use various parts of the code. There are also components from other people that I have incorporated into the code - these are listed in the later Third Party Code section.

Over the years it has been enhanced to support options like case-insensitive searches, alignment, etc. Many people have used or copied this. Since then it has found numerous uses in HexEdit as well as being used by many other people such as in the color range selection Colors page of Options dialog or the matching range of values for a CASE of a template SWITCH statement. CSystemSound - Contains very simple but effective system for defining and playing Windows sounds as seen in the Sound Control Panel applet.

HexEdit uses this for many sounds such as for searches. UpdateChecker - Simple class to read a version number from a text file on the Internet. HexEdit uses this for its monthly check for updates. CReadSRecord and CWriteSRecord - Classes used in HexEdit to import to and export from Motorola-S format files. Similar classes exist for Intel-hex files. CXmlTree - Class that wraps the Microsoft XML SDK DOM based to make it easily to process XML template files.

CCrypto - Class that wraps some of the Microsoft Crypto API. This is used to implement the encryption commands. Currently it only stores information about all the single key encryption algorithms not public key.

It also stores the current password. CPointAp, CRectAp, CSizeAp - Originally I used the MFC CPoint, CRect and CSize classes but these had limitations on coordinate sizes originally were 16-bit and are still limited to 32-bit coordinates. The "Ap" classes support 64-bit coordinates on the X-axis, and 32-bits on the Y-axis. These classes were necessary for the HexEdit views to properly display huge files.

CDirDialog CFileDialog derived class that allows the user to select a directory folder by "subclassing" the standard Windows file open dialog. Unlike the Windows recommended SHBrowseForFolder horrible it has many useful features such as being able to see options files in a directory, pasting a full path name, etc, etc. CTipWnd CWnd derived class for displaying a small tip window. Use in various places in HexEdit such as Info Tip windows.

CFileNC - File handling class derived from CFile see below for non-cached sector-based access. This is necessary according to MSWindows documentation for raw disk and volume reading used in disk editor. Note that other disk editors do not used non-cached file access, which contravenes Microsoft guidelines but seems to work and in fact makes them faster. CHexFileDialog - This is derived from the MFC CFileDialog class and is the base class for all the standard file dialogs open, save, ect.

CScrView - This was the first class I ever wrote for HexEdit. It is derived from the MFC CView class and is the base class for the main view class CHexEditView. I wrote it to be similar to CScrollView which I found had limitations. It is probably not that well designed but other people have used it in their software and found it useful.

CHexEdit, CDecEdit - Text controls that override the MFC CEdit class text box to allow editing of hex and decimal numbers, including space or comma separators. CHexEditSplitter - Overrides the MFC CSplitterWnd to allows a dynamic fixed maximum number of split windows in each file window.

This is used to allow the template and aerial views to be displayed in split windows next to the normal hex view.

These are used in the display of many user-interface elements. Number formatting functions are used in in various places in the user interface. NumScale is used for abbreviated display of large numbers eg KByte, MByte etc. These are quite complex and took me a lot of work. Multiple monitor routines are used to make HexEdit behave well in a variety of situations that confuse other programs.

Functions are: OutsideMonitorMonitorMouseMonitorRect. There are many pieces of code that I have incorporated into HexEdit to save writing them myself. These are all open source and generally, I have included the source code. CodeProject was an invaluable resource as most of the code listed below is MFC extensions that I found right here at CodeProject all except zlib, FreeImage, Boost and CFile I have not included the source for FreeImage as it is 10MBytes but you can download it from SourceForge.

I have not included all the source for Boost, only the parts that are used by HexEdit as it is huge - you can download the full source code, documentation etc from their web site. The installer that I use WIX is also open source but I have not included the WIX source only the files needed to build the installation.

I also use a commercial help compiler so I have not included the source files for the help system. As far as I am aware all of the code that I have incorporated into HexEdit is open source and free for reuse.

Please email me if I have violated any licensing terms and I will rectify the situation. Currently I only use the CRC and PRNG facilities. ZLIB Compression library by Jean-loup Gailly and Mark Adler - This is a free general purpose compression library with C source available which is used extensively in the industry.

I would consider it to be a de facto standard. I added this in HexEdit partly for my own convenience as I have used the ZLIB library in several other projects.

The Compression Options dialog offers complete control of all ZLIB options. It made possible the HexEdit Aerial View bit is also used in other places in HexEdit. It has been ported to several platforms but we only use the Win32 DLL that they provide. MFC Grid Control by Chris Maunder - An excellent grid control, which is used in several places in HexEdit - for example, in the Filters page and the Info Tips page of the Options dialog, the Recent File dialog and also with Tree Extensions - see below the template tree view.

MFC Grid Tree Extensions by Ken Bertelson - An extension to the MFC grid control that allows one of the columns to act as a "tree control". This allows the effect of a multi-column tree control which is invaluable for the HexEdit template tree view. CFile64 Class by Sam Blackburn - When I released the source code for HexEdit inSam enhanced it to use "64-bit" file access, thereby allowing HexEdit to easily work with files greater than 4 GBytes in size. Windows supports 64 bit file positioning but the MFC CFile class only allowed 32-bit file addresses.

Website no longer available. Window Splitter class by Robert A. Unlike MFC splitters I found it very easy to use and extend for my needs. This is used for all resizable dialogs in HexEdit such as the Recent File dialog, Bookmarks dialog etc. The Microsoft compiler only supports integers up to 64-bits but I found this class at CodeProject. Despite some caveats on its use by the author I cannot fault it bars extensive testing.

Transparent Static Controls by Ali Rafiee - An MFC class that provides "see through" static controls. It is used in the HexEdit About box. MD5 algorithm by Ron Rivest - Options algorithm is a cryptographic checksum sometimes also called a one-way hash function or message digest. It generates a bit value that is often used to check the veracity of files transferred over an insecure link in order to detect tampering. The MD5 command was added to HexEdit as an MD5 value is often provided for files downloaded via the Internet.

WIX Installer Toolkit by Rob Mensching et al - A free MSI based installer which produces nice enough installations and is very flexible. However, it bars somewhat difficult to understand and use. Subversion source control by Jim Blandy et al - Not part of the source code but crucial to the development, SVN sub-version provides an excellent free version control system.

I have used many version control systems and this is easily the best. SVN itself only provides command line tools. In the past I have found version control a pain but TSVN actually makes it enjoyable. This was some code changes to improve the "marching ants" display in the Aerial View using double-buffering.

It uses the little-known CMemDC class that comes with MFC. Aerial View is an alternative view of a file where each byte is shown as a single pixel the color of which is determined by the current color scheme. It is suprisingly useful as a high-level overview of a file. The Aerial View is also useful for getting an idea of where in the file different things are such as search occurrences, bookmarks, the selection etc.

This can be shown in the left border of the Aerial View and within the view as "marching ants". Marching ants are like a slowly moving trail of ants. This makes them easier to see as the human eye is very good at detecting movement. The problem with marching ants in HexEdit was that they are only drawn one pixel wide and when zoomed in on the Aerial View they were not as obvious as they could be.

It was an easy matter to drawn the ants wider when zoomed in but this caused a flicker which was not obvious when the ants were thinner. Which brings us to double-buffering. The flickering is a classic example of why "double-buffering" was invented. It is caused by the background the aerial view bitmap being drawn over the top of the old ants before the new ants are drawn at a slight offset. Double-buffering is used for animation by drawing each new image in an offscreen buffer before showing it.

In this way artifacts of the drawing process are not visible to the user. It was a simple matter to convert the code to use double-buffering using the CMemDC class. Having separate erase and draw stages is useful for a few reasons eg to avoid flickering by drawing using the noErase flag but since we are using double-buffering the need for the separate erase stage is obviated - instead we just erase at the start of drawing.

When the CMemDC instance is destructed at the end of OnDraw it automatically BLTs the offscreen buffer to the display. However, when I tried to compile the CMemDC code I got a name conflict. It seems that at some stage MFC added a CMemDC class of its own.

So I used the MFC CMemDC class instead. Bugs I do not believe there are many bugs in HexEdit, though there are a few design flaws. If you find a bug please report it in the HexEdit Bugs forum.

Even better would be if you could track down the cause and send a fix. I am more than willing to incorporate enhancements into HexEdit if you would like to submit code changes. You should probably check with me before you start to avoid duplication of effort. If you have an idea for a template for a specific file format please contact us.

If you have any problems creating or debugging your template please email me as I am very willing to assist. HexEdit has several improvements over earlier versions. The main change is moving to the new MFC and using the dockable windows and other new GUI features But the most popular feature is still the template system. If nothing else you may find HexEdit useful simply for viewing or editing binary data.

You might be able to use of some of the code or discover how to use facilities of the new MFC. If you are really keen you can tinker with it and add features that you require. July Minor update for official release of HexEdit Created three separate downloads: binary, project, extra build files.

HexEdit makes my life much easier when it comes to deciphering garbage text files. There was no support for this in MFC in It does support regional numeric and date formats if configured in the Control Panel. You could change all the English text in resource editors dialog editor, etc but that would take a lot of time and would not be updateable when I add new features to HexEdit.

One way around that may be to use an ANSI code page that supports the Unicode characters in the file name, or just rename the file before opening it. Thank you for sharing The amount of customization is amazing and extremely useful. However, I have yet to figure out how to apply it to every file. The settings remain on the file I set them but are lost on all others.

What am I missing here? A second rather trivial question, the quality of the icons is low and using the "large" option distorts them. Is there an icon pack or some such available? Sorry, there are no higher resolution icons. Interpreting the bytes as a pixel array? Especially for files such as BMP? Thanks in advance and thank you for this software!

Note that this does not display an image from a BMP files though sometimes you can sort of see the image. I have a beta version which allows preview of image file BMP, JPEG, PNG, etcif you are interested. Twine Jan James R. Twine Jan Fantastic product - great work!

If you think it costs a lot to do it rightjust wait until you find out how much it costs to do it wrong! Remember that Professional Driver on Closed Course does not mean your Dumb Ass on a Public Road!

Watch out for motorcyclists! Hex editors are always useful. Also, is there any way to use this to look at raw disk sectors, like the MBR? I added the above check after I accidentally shipped an 8-bit instead of a 24-bit background image.

In Windows Explorer right-click the file and select Properties, then in the Details page look for the bit depth which should be 24 or Removing the VERIFY is not a good idea, as px is not initialized and this may cause problems. Form memory, I think this causes the rest of the background to be filled with a random colour, but I have a feeling it may even cause worse problems.

However, when I opened binary in IrfanView a freeware image utilityit reported that it was only 8 bits. A wonderful safety feature of your program is that it opens physical sectors in Read-Only mode by default, which should help keep me from destroying my drives. While it does use open source software as a rule, that is not a panacea and you seem to be pulling from both open source i.

Specifically, you rely on two project whose license is GPL FreeImage and Tortoisewhich quite specifically require that your entire software will be licensed under the GPL, while another software project you rely on uses the MS-rL license which requires that all source files incorporating MS-rL code be licensed under MS-rL.

All the while your code is licensed under MIT. I have looked fairly closely at the licensing of all the code and believe I have not violated anything. Specifically, I have not modified and do not distribute the FreeImage source code. From the FreeImage web site you can use the library binary in any free or even commercial library as long as you acknowledge it in the About box and the manual. I have acknowledged in the About box, the help file, etc. I believe I have gone beyond that and actively promoted this excellent library in many ways.

I also do not distribute SVN, or TSVN in any way binary or source. I only mentioned them as I like to promote open source software that I find useful. The MS-rL software you refer to is, I believe, WIX. Again I do not distribute WIX. I only provide installer source files that can be used with WIX.

Of these, two are easily replaced if necessary, and the other Big Integer I have plans to replace with the MPIR library binary only which also uses GPL Windows Splitter: I downloaded the source code for this from CodeProject when it had a specific policy that all projects should be free to use even for commercial useso I am almost certain that it is OK. I have tried to contact the author Robert A.

I hope this satisfies your concerns. Please post a followup comment if this is not satisfactory or you find anything else that needs clarification. I would only hope that more people are informed as you are, and if your message above would help to enlighten bars of the readers then I think this whole exchange was well worth it. I will tidy up those and any other memory "leaks" I find.

These are not serious though, since they are simply one-off memory allocations. Perhaps memory "splash" would be a better name. What I think of as memory leaks are where the software continually drains memory until it is exhausted. These can be bad depending on how fast it happens.

I can make the old source available if you want to play around with it. There were a few bugs fixed and a few minor enhancements.

You can see all the code changes in the SVN repository at SourceForge SVN repository for HexEdit I also include project and solution files for VS Visual Studio I have updated and submitted a new version of the above article. Hopefully, it appears here soon. The file is "afxwin. I ran the debug build and noticed that this line threw an assert warning every time. Open-source hex range with powerful binary templates Download Source code MB Download Extra files needed to build a project MB Introduction After being in beta since the last year I have finally released the official version of HexEdit The beta version worked fine so I have not been in too much of a hurry to release it.

You can use the program or any of the source code for whatever purpose you see fit as long as you abide by the relatively unrestrictive license requirements see below or any specific requirements for any of the included 3rd party code Development History I wrote HexEdit in as it was something I needed in my work and the hex editors available at the time were poor. In fact it borrowed many ideas from these and other common Windows programs HexEdit In JanuaryI released HexEdit with source code to the public and got a lot of positive feedback.

Some of the acclaimed features of the first version were unlimited undo everything not just file changeseditable file size not limited to memory size, EBCDIC support, simple but fast searches and file compares, keystroke macros The most useful was the floating "Properties" window which could show all sorts of interesting stuff about the byte s at the current cursor position in the active file At that time I had a huge list of things that I wanted to add - some were user suggestions but mainly they were my own ideas.

I have actually implemented both of these in the past but they were not of sufficiently high quality to be added to the released version HexEdit In I released HexEdit shareware which used the very cool BCG library. I have always made earlier versions about years behind the shareware version available for free with source code on request In the intervening years I have added most of the the abovementioned features and many more binary my TODO list is longer than ever!

The max line length was increased to 32, HexEdit In this version of HexEdit I converted the code from using BCG to MFC9. The dockable windows are the Properties dialog, Find dialog, Calculator, Bookmarks dialog and Explorer window Features HexEdit has very many useful features which I can only just touch on here. Here I will just explain the general philosophies of the design of HexEdit and introduce a few features as examples One thing to remember is that if you need a feature it might already be there.

I often get emails asking for a specific feature which is already present Try to find it in the help Another thing to remember is that if you often find yourself spending a lot of time doing a tedious or repetitive task then there is probably a feature in HexEdit to save you time. Another type of email I get is from users saying they found a useful feature that they did not even know they needed but has since saved them a lot of time Simple An overriding principle has been to keep the user interface as simple and uncluttered as possible.

Of course, if you need it there is lots of help available Mark The mark is a simple facility that allows you to mark a position in a file and return to it later. It is also useful in many other areas such as keystroke macros I think I got this idea from a text editor I used pEdit, Epsilon or Emacs Help Options problem with keeping the user interface simple is that some of the more powerful features may not be obvious.

For example, many hex editors use the Tab key to switch between the hex and character areas There is also a de facto standard for the behavior of cursor keys, mouse, etc as seen in many editors.

When the background search is finished you can immediately see all occurrences highlighted in a special color The background search will normally be completed before you even notice unless you are working with very large files - but while it is running the progress is displayed in the background search occurrences pane.

When finished a count of the occurrences is shown in the status bar pane Huge Files HexEdit has always easily edited files of any size without any extra effort on the part of the user. Progress is shown in the status bar and you can, of course, abort the operation by pressing the Spacebar or Escape key Customizable The ability to configure HexEdit has always been important.

The user should be able to decide how they want to work Toolbars In HexEdit I incorporated the BCG library which among many other things allowed for complete customization of the toolbars, keyboard, menus including many context menusetc Info Tips Many programs show a small usually yellow tip window when you hold the mouse over an item of interest.

HexEdit takes this further with Info Tips In a binary editor what you find interesting about some of the bytes of a file may not be what someone else does, and can change for different circumstances. Info Tips allow you to create one or more tips based on several predefined values addresses, offsets, file data etc and using C-like expressions and with many formatting options You can perform calculations on addresses.

Since HexEdit allows you to work with any type of file you can customize this filter list any way you like You can add or delete filters in the Options dialog on the "File Type Filters" page. Since you may work with different types of files at different times you can turn the filters on and off without deleting them using the checkboxes Moreover the same filter list is available in the "HexEdit Explorer" window. This is another example of integration between the features see below Compatible Not only is the user-interface compatible with what you are used to in other programs, HexEdit also attempts to work well with other software Clipboard When using the clipboard HexEdit supports text data and binary data.

HexEdit includes many nice features such as support for noncontiguous records You can also import and export using hex text, where each byte is stored as 2 hex digits in ASCII. For CSV format use the Copy As C Source dialog see above Flexible One thing about HexEdit that many users have commented on is the simple tool set that provides the flexibility to easily perform a wide variety of tasks Jump Tools On the Edit toolbar are two simple drop-down lists that provide a large number of facilities.

The drop-down lists provide a history of the last addresses jumped to But they also do a lot more. To remember an address by adding it to the history it is simply a matter of clicking in the tool and pressing Enter A further feature is that as you type a value into one tool, the corresponding value is shown in the other tool. This allows quick and easy conversion between hex and decimal Finally, you can evaluate any expression in these tools including assigning to variables that are stored between sessions.

You can have any number of jump tools visible by customizing the toolbars Keystroke Macros Sometimes I get a request for a feature where I just have to say "no", because it is just too special to be of general use. Even then, most of the time I can simply point out how the feature can be accomplished by using existing an existing tool or a combination of tools One of the most flexible capabilities is provided by keystroke macros.

Many users do not realize that macros can work between files so you can do things like copy a bit of a file and paste it into a temporary file for further manipulation Macros can also call other macros.

This is demonstrated in the "AllChars" macros distributed with HexEdit which creates a new file and fills it with all different byte values Integrated Part of the flexibility of HexEdit is that there are many simple tools that have been designed to work together.

Here are some more examples Color Schemes Color schemes are useful for setting up the colors used for other features such as bookmarks, search occurrences, change tracking etc One very useful feature of color schemes is the ability to display colors for ranges of byte values.

For example, in the default ASCII color scheme normal text is blue while control characters are red, except for the control characters that are normally found in text files tab, CR, etc which are green The use of color schemes is also crucial in combination with the aerial view feature.

If you have particular byte value s that you are interested in you can create a color scheme to show up the value or range of values in the aerial view If you have a file format which you know nothing about you can use the "rainbow" color scheme to get an idea of the different byte values in the file - this often immediately shows up areas of interest Searches Searches are another area where the various tools work well together.

For example, the history list of the search tool edit toolbar is integrated with the search histories in the different pages of the Find dialog Another example is that the Find dialog can set bookmarks at all found occurrences The Find dialog also supports aligned searches which are a very useful and powerful feature.

There are several pages so you can see information about integers, floating point numbers, dates, etc Templates Since its introduction the template system has easily been the feature that has attracted the most interest. With expressions you can analyze just about any type of field from a file and use that to control the evaluation of the template Expressions can be used to control branching IF and SWITCH and loops FOR with counter or with terminating condition.

STRUCTs can be self-referential so you can model recursive data structures An example of the power of templates is that they can be used to look into a filesystem when combined with the disk editor to display information and the data from say, a deleted file. The parser supports all parts of the C standard preprocessor, unions, bit-fields, etc and even some extra things like pragma pack Programmer focused Binary editors are the domain of programmers so many of the features are aimed squarely at programmers.

Similarly formatting as in templates, Info Tips etc are based on printf format specifiers or strftime formats for dates zlib Zlib is the de facto standard for data compression. Zip files also support other algorithms but nowadays files are generally compressed with "deflate" as it is the best Over the years I have worked on several projects that used zlib. Now I can just load my data into HexEdit to test the different zlib options Building HexEdit To build HexEdit you need to download one or two of the above zip files.

I have been told that you cannot use the free Visual Studio Express editions as they do not include MFC Depending on what you want to do you may need some other free tools.

If you have VS but not the feature pack you can download it here To set up VS to find the FreeImage and Boost files you need to add to the Include files and Library files locations. You do not need to install the MFC Feature Pack The Include files and Library files locations for FreeImage and Boost should already be set up in the correct sub-directory. The classes CHexEditView and CHexEditDoc provide the core of HexEdit, by implementing the view and document of the Document-View model A core part is the ability to handle huge files keeping track of changes in memory and temporary disk files.

Apart from that, the best way I can think to give an overview of the code is to explain the contents of each of the files I will just list the header. There are exceptions as noted HexEdit.

There are also components from other people that I have incorporated into the code - these are listed in the later Third Party Code section Classes boyer - Implements Boyer-Moore algorithm for searching a memory block. Over the years it has been enhanced to support options like case-insensitive searches, alignment, etc timer - Utility class used for timing tests. Since then it has found numerous uses in HexEdit as well as being used by many other people such as in the color range selection Colors page of Options dialog or the matching range of values for a CASE of a template SWITCH statement CSystemSound - Contains very simple but effective system for defining and playing Windows sounds as seen in the Sound Control Panel applet.

Options uses this for many sounds such as for searches UpdateChecker - Simple class to read a version number from a text file on the Internet. HexEdit uses this for its monthly check for updates CReadSRecord and CWriteSRecord - Classes used in HexEdit to import to and export from Motorola-S format files.

Similar classes exist for Intel-hex files CXmlTree - Class that wraps the Microsoft XML SDK DOM based to make it easily to process XML template files. It also stores the current password CPointAp, CRectAp, CSizeAp - Originally I used the MFC CPoint, CRect and CSize classes but these had limitations on coordinate sizes originally were 16-bit and are still limited to 32-bit coordinates.

These classes were necessary for the HexEdit views to properly display huge files CDirDialog CFileDialog derived class that allows the user to select a directory folder by "subclassing" the standard Windows file open dialog. Unlike the Windows recommended SHBrowseForFolder horrible it has many useful features such as being able to see the files in a directory, pasting a full path name, etc, etc CTipWnd CWnd derived class for displaying a small tip window.

Note that other disk editors do not used non-cached file access, which contravenes Microsoft guidelines but seems to work and in fact makes them faster CHexFileDialog - This is derived from the MFC CFileDialog class and is the base class for all the standard file dialogs open, save, ect. It is probably not that well designed but other people have used it in their software and found it useful CHexEdit, CDecEdit - Text controls that override the MFC CEdit class text box to allow editing of hex and decimal numbers, including space or comma separators CHexEditSplitter - Overrides the MFC CSplitterWnd to allows a dynamic fixed maximum number of split windows in each file window.

These are used in the display of many user-interface elements Number formatting functions are used in in various places in the user interface. These are quite complex and took me a lot of work Date conversion functions are used in the Date Properties page Multiple monitor routines are used to make HexEdit behave well in a variety of situations that confuse other programs. Functions are: OutsideMonitorMonitorMouseMonitorRect Third Party Code There are many pieces of code that I have incorporated into HexEdit to save writing them myself.

I have not included all the source for Boost, only the parts that are used by HexEdit as it is huge - you can download the full source code, documentation etc from their web site The installer that I use WIX is also open source but I have not included the WIX source only the files needed to build the installation. Website no longer available Window Splitter class by Robert A. The MD5 command was added to HexEdit as an MD5 value is often provided for files downloaded via the Internet WIX Installer Toolkit by Rob Mensching et al - A free MSI based installer which produces nice enough installations and is very flexible.

It is suprisingly useful as a high-level overview of a file The Aerial View is also useful for getting an idea of where in the file different things are such as search occurrences, bookmarks, the selection etc. This makes them easier to see as the human eye is very good at detecting movement The problem with marching ants in HexEdit was that they are only drawn one pixel wide and when zoomed in on the Aerial View they were not as obvious as they could be.

Which brings us to double-buffering The flickering is a classic example of why "double-buffering" was invented. In this way artifacts of the drawing process are not visible to the user It was a simple matter to convert the code to use double-buffering using the CMemDC class. When the CMemDC instance is destructed at the end of OnDraw it automatically BLTs the offscreen buffer to the display However, when I tried to compile the CMemDC code I got a name conflict.

Even better would be if you could track down the cause and send a fix Enhancements I am more than willing to incorporate enhancements into HexEdit if you would like to submit code changes. You should probably check with me before you start to avoid duplication of effort Templates Several users of HexEdit have submitted templates which are included with the distribution If you have an idea for a template for a specific file format please contact us.

If you have any problems creating or debugging your template please email me as I am very willing to assist Conclusion HexEdit has several improvements over earlier versions. The main change is moving to the new MFC and using the dockable windows and other new GUI features But the most popular feature is still the template system If nothing else you may find HexEdit useful simply for viewing or editing binary data.

If you are really keen you can tinker with it and add features that you require History Jan First article to coincide with release of HexEdit beta July Minor update for official release of HexEdit Created three separate downloads: binary, project, extra build files.

The code has numerous minor bug fixes and a few improvements over the last beat version There is also a project files for VS This article, along with any associated source code and files, is licensed under The MIT License email twitter facebook linkedin reddit google Andrew Phillips Andrew has a BSc from Sydney University in Computer Science and Mathematics. The customization options for display is amazing. Member Dec The program itself is very good, but why the application that targets Windows NT family is not Unicode-aware?

Then it was returning non-Unicode characters when LPCTSTR was declared Oh, missing Unicode support is a real miss. Andrew Phillips Apr HexEdit started off as an ANSI project since it ran on Windows Over the years I added support for Unicode display but it still cannot handle Unicode file names.

Twine Fantastic product - great work! And nice to see other "old-schoolers" around, although I "only" started to learn programming in Thanks again. I expect to learn a great deal, both about programming and NTFS structures, from using your program Thanks again for the very generous donation of your time and expertise.

As far as I understand licensing IANALthis project is in violation of copyright of several authors, unless you have specific permissions from each - in which case I would like to know about as I was planning to share this project with a few customers and I would not like to find myself in a legal bind. Thanks for your excellent work, look forward to using the new version and appreciate the back story.
