 *
 * exports DllMain, DllCanUnloadNow, DllGetClassObject, DllRegisterServer and DllUnregisterServer
 * The wizard generated code is slightly modified:
 * To run this tool you need WinXP. The DllRegisterServer checks if the current system is 
 * a WinXP system and fails with an error message if not.
