TCHAR szPath[MAX_PATH];
if( !GetModuleFileName(NULL, szPath, MAX_PATH ))

 return _T("");
}
CString strPath(szPath);
int nPos = strPath.ReverseFind('\\');

或者

TCHAR szFname[_MAX_FNAME] = { 0 };
TCHAR szExt[_MAX_EXT] = { 0 };
(void)::GetModuleFileName( NULL, szPathName, MAX_PATH );
_splitpath( szPathName, szDrive, szDir, szFname, szExt );
