Open the Class Wizard for the application class.

In the Messages list, highlight PreTranslateMessage and then click Add Function.

Click Edit Code.

The PreTranslateMessage method appears.

Change the PreTranslateMessage method to read as follows:

BOOL CMyApp::PreTranslateMessage(MSG* pMsg)
{
 if( ULIsSynchronizeMessage(pMsg->message) ) {
  DoSync();
  // close application if launched by provider
  if( pMsg->wParam == 1 ) {
   ASSERT( AfxGetMainWnd() != NULL );
   AfxGetMainWnd()->SendMessage( WM_CLOSE );
  }
  return TRUE; // message has been processed
 }
 return CWinApp::PreTranslateMessage(pMsg);
}

where the DoSync method calls the ULSynchronize method.
