SUMMARY

Sample Code

   INmManager * g_pMgr  = NULL;
   HRESULT hr;
   // Start NetMeeing manager
   if (FAILED(CoCreateInstance
      (CLSID_NmManager,NULL,CLSCTX_INPROC_SERVER,IID_INmManager,
      (VOID **)&g_pMgr)))
      return FALSE;

   ULONG uchCaps = 0;
   ULONG uOptions = (ULONG) 1; // NM_INIT_CONTROL;
   // The following will run NetMeeting in the background
   hr = g_pMgr->Initialize(&uOptions, &uchCaps);
   if (S_OK == hr) // NetMeeting initailizes successfully in the background
   {
      char szNMDir[300]; // To hold the path name of NetMeeting wb32.exe
      strcpy (szNMDir, "Directory path to wb32.exe");
      HINSTANCE Hinst = ShellExecute( NULL, NULL, szNMDir,
                                      NULL,NULL,SW_NORMAL );
   }

You can also programmatically obtain the NetMeeting installation directory from the registry.
