C++ asm help. Patching a program in runtime [newbie question]

Hey guys,

So I'm attempting to patch a program using inline asm in C++ while the program is running.

What i'm trying todo in C++ is this for eg:

Turning
00482F02 8D51 19 LEA EDX,DWORD PTR DS:[ECX+19] 00482F0B 83C1 19 ADD ECX,19

Into
00482F02 8D51 14 LEA EDX,DWORD PTR DS:[ECX+14] 00482F0B 83C1 14 ADD ECX,14But I just cant find anything to help which is why I came here, I'd like to use Microsoft Detours 2.1 todo this but im 99% it doesn't support this kinda job

Thanks,
Dread
