public bool _result = false; 
public ConvertCtrlForm _form = new ConvertCtrlForm(); 
 
public void ResetSourceExample() 
{ 
   // reference the convert control 
   ConvertCtrl convertctrl = _form.ConvertCtrl; 
 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_Source.avi"); 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "ConvertCtrl_ResetSourceExample.MP4"); 
 
   try 
   { 
      // set the input and output files 
      convertctrl.SourceFile = inFile; 
      convertctrl.TargetFile = outFile; 
 
      // select the target format 
      convertctrl.TargetFormat = TargetFormatType.MP4; 
 
      // select video and audio target formats for the output 
      int index = -1;
