I don't think it wants an addr to the file name - try loading the file into memory and pass the memory pointer inside UpdateResource.

HANDLE BeginUpdateResource(LPCTSTR pFileName, BOOL DeleteExistingResources);

So it does want filename.

I remember playing around with this a bit, and there was some trickery wrt. the resource LangIDs - can't remember the specifics though, and I'm heading out now...

Yes f0dder, BeginUpdateResource needs the filename of the file you want to edit. But UpdateResource, which does the actual job, does not want the filename of the icon - instead it wants a pointer to a buffer with the "to replace" data.


BOOL UpdateResource(? ? ?

? ? HANDLE hUpdate,
? ? LPCTSTR lpType,
? ? LPCTSTR lpName,
? ? WORD wLanguage,
? ? LPVOID lpData,
? ? DWORD cbData
);


I might have explained myself wrong ;)

One more thing, BeginUpdateResource() system call and such do not work on Windows 95/98/ME... Although you can call them in mentioned Operating Systems, the Kernel will not do anything but ignoring the calls.
