How Can I create a webcam chat in internal network using C# windows forms
Hello , can you help me to create a webcam chat application, i tried to use sockets but i had problems such as the size of the buffer didn't match and some other things ..
i put the tcpclinet and the tcplistenert in the timer function (tick1).
the first part receive an image as a byte array and convert it to image .
the second part send an image from converting it to byte array.
i really need your help.
i used dll named WebCamLib.dll to preview the images from the webcam into the picturebox and i really worked but i had problems the sockets part i think .
i have two picturew boxes . the first preview the picture from the webcam ... the second one preview the picture from the clint.
this is the code i used (C# Code):

static Byte[] bufferr { get; set; }
       static Socket sok;
       Image aa;
       bool time = false;

1- Convert byte to image array

public Byte[] imageToByteArray(System.Drawing.Image imageIn)
        {
            MemoryStream ms = new MemoryStream();
            imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            return ms.ToArray();
        }

2-The Send And The receive part using sockets in tick1 function
Receive :

private void timer1_Tick(object sender, EventArgs e)
       {
           try
           {
               sok = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
               sok.Bind(new IPEndPoint(0, 1993));

               sok.Listen(100);
               Socket acc = sck.Accept();
               bufferr = new Byte[acc.sendbuffersize];
               acc.Receive(bufferr, bufferr.Length, SocketFlags.None);
               if (acc.Connected)
               {
                   label2.Text = "ONLINE";
                   label2.ForeColor = Color.Green;
                   pictureBox1.Image = ByteArrayToImage(bufferr);
                   aa = pictureBox2.Image;
                   pictureBox2.SizeMode = System.Windows.Forms.PictureBoxSizeMode.Zoom;
               }
               sck.Close();
               acc.Close();
           }
           catch
           {
           }

Send (also in the same function with the receive part) :

/
/===========================================================================
                //SEND PART =================================================================
                //===========================================================================
            sck = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
            IPEndPoint ipe = new IPEndPoint(IPAddress.Parse("192.168.0.2"),1993);
            try
            {
                sck.Connect(ipe);
                send = true;
            }
            catch
            {
                send = false;
            }

            if (send)
            {
               sck.Send(imageToByteArray(pictureBox1.Image), imageToByteArray(pictureBox1.Image).Length, SocketFlags.None);
            }

3- Convert Image to byte array :

public Image ByteArrayToImage(Byte[] ByteArrayIn)
       {
           MemoryStream ms = new MemoryStream(ByteArrayIn);
           Image returnImage = Image.FromStream(ms);
           return returnImage;
       }

4- button 1 (startchating) start taking pictures to picturebox1 from a webcam

<pre lang="cs">private void button1_Click(object sender, EventArgs e)
        {
            Device d = DeviceManager.GetDevice(cmbDevices.SelectedIndex);
            d.ShowWindow(this.pictureBox1);
            pictureBox1.SizeMode = System.Windows.Forms.PictureBoxSizeMode.StretchImage;
            timer1.Enabled = true;
        }

5- Select webcam combobox

<pre lang="cs">private void Form1_Load(object sender, EventArgs e)
      {
          Device[] devices = DeviceManager.GetAllDevices();
          foreach (Device d in devices)
          {
              cmbDevices.Items.Add(d);
          }

          if (devices.Length > 0)
          {
              cmbDevices.SelectedIndex = 0;
          }
      }

Thank you for reading and i really need a solution.
