    GetModuleHandle

    I know that when you are not working with any DLL's that GetModuleHandle(0) is a perfect way to retrive hInstance and not have to make it global. However, in the project I'm working on now I am using DLL's and I'm wondering if it is okay to use GetModuleHandle(0) here and if not what is another possibility?

    Depends on which handle you want. If you want the DLL's handle then you'll need to pass the DDL's name.

    If working on a DLL you could store the hInstance from DllMain in a global variable. Other methods are discussed here. By my reading of the documentation the following code should also work. By the complicated workarounds posted on the web I suspect it doesn't, but it's worth a try.
    Code:
    GetModuleFileName(NULL, szModule, MAX_PATH);
    GetModuleHandle(szModule);
