Question

I have a program that is executed by another program. The program that is being executed needs files located at its own location [same folder]. If I call myfile.open(“xpo.dll”) I might get an error because I am not passing the [fullpath + name + extension]. The program that is being executed can vary paths depending on the installation path. Therefore, I was wondering if there is a way to get the application path [where the application is located] and set it so that when another program executes from another path everything might work properly…?

Thanks.

Use GetModuleFileName and pass NULL for hModule.

DWORD GetModuleFileName(
    HMODULE hModule,   // handle to module
    LPTSTR lpFilename, // path buffer
    DWORD nSize        // size of buffer
);
