The path and name of the executable file are stored in the first command line argument array entry that is passed to the main function. So you may copy that or store a pointer.

Alternatively you can use the GetModuleFileName()[^] function:

// Get path of the executable file of the current process
TCHAR path[MAX_PATH];
GetModuleFileName(GetModuleHandle(NULL), path, MAX_PATH);
// Remove the file name
// Set ext[0] to zero to strip also the trailing back slash
LPCTSTR ext = _tcsrchr(path, _T('\\'));
if (ext)
    ext[1] = _T('\0');
