Example
C#
using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(false); 
 
public void CaptureStillDelayExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   // output file 
   string outFile = Path.Combine(LEAD_VARS.MediaDir, "CaptureCtrl_CaptureStillDelayExample.jpg"); 
 
   try 
   { 
      // set the video capture device, use your capture device name here 
      if (capturectrl.VideoDevices["USB"] == null) 
         throw new Exception("No USB video device available"); 
 
      capturectrl.VideoDevices["USB"].Selected = true; 
 
      // set the still capture delay 
      capturectrl.CaptureStillDelay = 1000; 
 
      // set the capture mode to still and start 
      capturectrl.StartCapture(CaptureMode.Still); 
 
      // get a still image 
      Image image = capturectrl.CaptureImage(); 
      if (image != null) 
         image.Save(outFile, ImageFormat.Jpeg); 
 
      // stop the capture 
      capturectrl.StopCapture(); 
 
      // check for the capture file and set the result 
      if (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), outFile))) 
         _result = true; 
   } 
   catch (Exception) 
   { 
      _result = false;
