-1) Nice tool. ))

ToDo:

1)
Use crack file:

24576 10-Jul-2016 23:12 CompareInfo.exe

Change EditBuffer size from 4'999 bytes to 300'000 bytes
CompareInfo.exe
.00401CA6: 88 E0 ;00001CA6:
.00401CA7: 13 93 ;00001CA7:
.00401CA8: 00 04 ;00001CA8:
CompareInfo.exe
.00401EBE: 88 E0 ;00001EBE:
.00401EBF: 13 93 ;00001EBF:
.00401EC0: 00 04 ;00001EC0:
CompareInfo.exe
.004025D8: 88 E0 ;000025D8:
.004025D9: 13 93 ;000025D9:
.004025DA: 00 04 ;000025DA:
CompareInfo.exe
.004025EF: 88 E0 ;000025EF:
.004025F0: 13 93 ;000025F0:
.004025F1: 00 04 ;000025F1:

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."

[CodeCracker]

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

[CodeCracker]

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

@Doit you need read the forum rules.

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:")

[CodeCracker]

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.

BTW, ChangeWindowMessageFilter is not recommended to use, there is ChangeWindowMessageFilterEx (win7+) instead, which controls a window-scope message filter. ChangeWindowMessageFilter controls a process-scope message filter.
Also, WM_DROPFILES is not enought to cover all cases of elevated processes, WM_COPYDATA and WM_COPYGLOBALDATA should be filtered too.

exelab domain expired year ago and owned by third party now, so actually dosprog's post had nothing suspicious in 2020.

[vic4key]

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.

[CodeCracker]

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.

[CodeCracker]

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.
