CompareInfo 1.0
Compare two files made easy. Show the different bytes of two files.

Old tool (2016)..

-1) Nice tool. ))

See -> this <-

ToDo:

1)
Use crack file:

2)
Add command line interface for usage:
"CompareInfo.exe 1.exe 2 exe"

3)
Add option "Save as .CRK"
for make cracks usable with CRACKER.EXE (WIN32) (See https://forum.exetools.com/showthread.php?t=18773)

4)
In option "Save as .CRK" add sub-option "Append to file."

- Added buffer split. sizeof buffer = 4096*4096 (1000h*1000h)

Added command line parameters parse
 

Added command line parameters parse:
Simple usage: CompareInfo.exe filetocompare1 filetocompare2 destinationfile
so parameter just have to be separated by a space; destinationfile (last parameter) is optional, if not present will write information to file.txt

External link, please.
Thanks

@Doit you need read the forum rules.

CompareInfo ideas
 

CodeCracker, thank you for tool!

Some wishes:

+ Add drag and drop support: `DragAcceptFiles` for file edit boxes (for both), then `DragQueryFile` when you receive `WM_DROPFILES` message (for each edit box).
+ Show file name on different lines in report (.txt)
+ Hide full path in report (.txt), leave only file names.
+ Use mono font for result edit box
+ Place difference line just after original line for better visual representation (without repeating text "Second file bytes:")

1. DragAcceptFiles: hard for me.
2. + Show file name on different lines in report (.txt)
I think filenames are shown already on different lines! Don't know what you mean!
3. + Use mono font for result edit box
Don't know what mono font is nor how to find it! Maybe they are some other ways?

I have code suggestions might help for quick support drag & drop by Windows API

• Enable drag & drop (supported Elevated right)
• Handle drag & drop

@Moderator(s) Let take a look at the post #4 (by dosprog), the link take me to a porn website.

Oh. I see. Its documentation in MSDN said clearly. Thanks for your information.
https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-changewindowmessagefilter

P.S About dosprog's post: Yes. So, ignore my mention.

For elevate process I think it has to be something like this:
https://gist.github.com/amspeople/8052306

DragAcceptFiles was hard for me because had two textboxes where to drag, I made it by filtering WndProcEditControl for each textbox. I succeed now everything.

Fixed elevated process and drag and drop support.
I can't fix yet the result hex string length to be properly displayed, displayed length of different hex string vary even if hex strings have same length.

I found some resources:
https://www.codeguru.com/cplusplus/hexedit-control/
https://www.codeproject.com/Articles/1271133/Hex-Control-for-Cplusplus-Win32-applications

So if someone know an easy fix for hex string display just let me know.

CompareInfo v3
 

CompareInfo v3:
- Added "Short file name" to show file names in this way
- Set font of result edit to Terminal font (monospace) for properly display hex bytes
- Now can drag and drop even of elevate mode
- Fixed various bugs

monospaced font
 

Finally you figured out:

Short list of well-crafted monospaced fonts:

• Fira Code
• Hack
• Iosevka
• Cascadia Code
• Plex Mono

New: fixed a bug
 

New: fixed a bug (comparing invalid memory location - fatal bug).

How do I download?

CompareInfo_v4
 

CompareInfo_v4:
- added "Skip diffbase" - to skip comparing comparing relocation
- added "Start with first section" to start comparing with first section skipping header

Hi,

On Windows XP SP3 PosReady 2009, CompareInfo does not load from version 3 onwards, however, earlier versions (1.00, 1.01, 2.00) load correctly.

73DDF10B | 53 | push ebx | 0x0
73DDF10C | 68 4567DD73 | push <mfc42.Ordinal#1130> | mfc42.Ordinal#1130
73DDF111 | 50 | push eax | 0x0
73DDF112 | FF75 08 | push dword ptr ss:[ebp+8] | compareinfo2.00406598 DLGTEMPLATEEX (01 00 FF FF)
73DDF115 | FF75 10 | push dword ptr ss:[ebp+10] | compareinfo2.00400000
73DDF118 | FF15 AC64E773 | call dword ptr ds:[<CreateDialogIndirectParam>] |

The v3 and v4 versions crash when calling the CreateDialogIndirectParam() API.

Cheers.
