Hooking BitBlt using Detours = crash

Question

1.50/5 (2 votes)

See more:

I made the injection-DLL with hooks of BitBlt, AlphaBlend, DrawTextEx and ExtTextOut functions using MS Detours. Every hook just calls original function and works fine except for BitBlt. Debugging in disassemly shows that the return address has some dummy value. Any ideas how to fix it? Is it a bug of Detours?
