      // get the current selected format 
      int n = capturectrl.TargetFormats.Selection; 
 
      // loop through the target formats and set a different one 
      foreach (TargetFormat t in capturectrl.TargetFormats)

         string name = t.Name;

      } 
 
      // check it directly 
      TargetFormatType tft = capturectrl.TargetFormat; 
 
      // set the result to what we expect 
      _result = (tft != TargetFormatType.MP4 && n != capturectrl.TargetFormats.Selection); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (capturectrl.State == CaptureState.Running) 
      Application.DoEvents();
