For testing I'm using what I guess is described as "Target Function Modification".

Microsoft released a new technology with later versions of XP (and Vista) that allows DLLs to be patched without restarting. This involved allocating space at the start of every function for a jump to be installed (that much I understand and am using) but also it seems to patch the DLLs themselves (something I don't want to do).

So far, I haven't managed to get my modifications to work (currently baffled) and I can manage without the clever hotpatching technology, but, assuming I can get my code to work, other programmers might find a signed hotpatch solution to this problem very useful.

Kaled.
