My project is about Remoting and i want to add a webcam component to it. Here it goes: I have 3 project in my solution... Client, Server, Remote.dll. In Remote.dll is a common class which has methods works in server machine. When i call these methods from Client it executes in server side. So now my question is i put the code of Webcam in remote.dll and it has an event called "video_NewFrame" which it works everytime when webcam catch an image. But i cant reach to the images from my Client side because when code drops to this event it executes infinitely and my timer in Client side doesnt work as well. I tried to assing image to my global variable but whenever code goes to client and comes to Remote.dll again my variable is null... How can i reach simultaneously captured images from my client? here is my code: (i use AForge framework for webcam)
private bool DeviceExist = true;
private FilterInfoCollection videoDevices;
private VideoCaptureDevice videoSource = null;
public bool WebCamStart(int DeviceIndex)
{
if (DeviceExist)
{
videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
//string myDevice = videoDevices[0].Name;
videoSource = new VideoCaptureDevice(videoDevices[0].MonikerString);
videoSource.NewFrame += new NewFrameEventHandler(video_NewFrame);
CloseVideoSource();
videoSource.DesiredFrameSize = new Size(640, 480);
//videoSource.DesiredFrameRate = 10;
videoSource.Start();
return true;
}
else return false;
}
public Bitmap lastImg;
private void video_NewFrame(object sender, NewFrameEventArgs eventArgs)
{
Bitmap img = (Bitmap)eventArgs.Frame.Clone();
//in executes infinitely when execution comes here and i cant reach from Cliend side...
}
public string getFPS()
{
return videoSource.FramesReceived.ToString();
}
public void CloseVideoSource()
{
if (!(videoSource == null))
if (videoSource.IsRunning)
{
videoSource.SignalToStop();
videoSource.Stop();
videoSource = null;
}
}
public string getCamList()
{
string result = "No Device Found";
try
{
videoDevices = new FilterInfoCollection(FilterCategory.VideoInputDevice);
//comboBox1.Items.Clear();
if (videoDevices.Count == 0)
throw new ApplicationException();
DeviceExist = true;
foreach (FilterInfo device in videoDevices)
{
//comboBox1.Items.Add(device.Name);
result = device.Name;
return result;
}
//comboBox1.SelectedIndex = 0; //make dafault to first cam
}
catch (ApplicationException)
{
DeviceExist = false;
//comboBox1.Items.Add("No capture device on your system");
return "No capture device on your system";
}
return result;
}
// and my client side...
private void timerWebCam_Tick(object sender, EventArgs e)
{
//lblFPS.Text ="Device Running... " + remObj.getFPS() + " FPS";
pictureBox1.Image = remObj.lastImg;
}
