Question

I am new to c++ and this code always returns NULL even though i know the file exists:

HMODULE hModule = GetModuleHandle(TEXT("C:\\Users\\Steve\\Desktop\\stub.exe"));

Interestingly, if i copy stub.exe to C:\Windows\system32, it finds the module with this code:

HMODULE hModule = GetModuleHandle(TEXT("stub.exe"));

Am i missing something incredibly basic?

You can only call GetModuleHandle(L"C:\\Users\\Steve\\Desktop\\stub.exe"); when you’re running C:\Users\Steve\Desktop\stub.exe.

But in general, you don’t call GetModuleHandle for your EXE name. Since there’s only one EXE per process, you just call GetModuleHandle(0).
