Request of patcher
-
Can anyone submit an article on patching binary files? I've tried myself, but the results are not very good: I get a patch file as big as the file compared :-( What I need is something like RTpatch, but free and with sources :-) If someone is interested I can send him my not-very-good code as a starting point. Thank you all Alessandro Vergani

Have you looked into the GNU tools for patching? They're free under GNU copyleft, provide source and are available on most platforms including Windows. Check any GNU archive for a copy or see the Gnu web site for more information.

The GNU tools (diff and patch) are good only for text files. I need a patcher for binary files.

You should investigate the patch dll that comes with the Microsoft Windows Installer SDK. This DLL has a function that accepts two files and outputs a third file that contains the 'patch' information to cause the first file to be transformed into the second file. Another function in the DLL can 'apply' the patch. There are various options for compression and such in the API.
