         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true; 
 
      // select the MP4 target format 
      capturectrl.TargetFormats[TargetFormatType.MP4].Selected = true; 
 
      // 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) 
      { 
         // get the format properties 
         string name = t.Name; 
         StreamFormatType sft = t.Streams; 
         bool available = t.Available;

            // if it is available then select it 
            if (available)

            break; 
         } 
      } 
 
      // 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();
