Problem loading .dll
I've been working on a speedhack, using Detours 2.1 (because I figure its time to move on). Anyhow the I did a bit of pruning to the detours header file so that I wouldn't have to require or ship detoured.dll with every hack I make....
The problem is its not working. I get no compile time errors, but it looks like as if in runtime there is no entry point for my .dll. At first I thought it might just be CA, but now I see it is failing in multiple applications. So if someone could take a look as to why it may not be loading properly I'd really appreciate it.
Right now it only detours QueryPerformanceCounter and timeGetTime, but I expect to add GetTickCount and implement a better UI, which you guys have already helped me with once I get the damned thing to work. =/
