   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   // output file 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "CaptureCtrl_CompressorsExample.avi"); 
 
   try

         throw new Exception("No USB audio device available"); 
 
      capturectrl.AudioDevices["USB"].Selected = true;

      // set the target files 
      capturectrl.TargetFile = outFile; 
 
      // check whether we can capture video 
      if (capturectrl.IsModeAvailable(CaptureMode.VideoAndAudio))

         capturectrl.StartCapture(CaptureMode.VideoAndAudio); 
      } 
   } 
   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)
