//this is on client side
MemoryStream mstream=new MemoryStream();
Bitmap b=new Bitmap(@"C:\Documents andSettings\jelena\Desktop\lud'lo diplomski\image\Frame.bmp");
    b.Save(mstream,System.Drawing.Imaging.ImageFormat. Bmp);
    byte[] ba=mstream.ToArray();
    BinaryWriter writer=new BinaryWriter(mstream);
    writer.Write(ba);

//the problem is to receive this bytes on server side and convert them back to bmp

Thank's in advance

Can you elaborate on "receive this bytes on server side"?
How are they being sent?
What type is 'writer'?

-Peter

socket=listener.AcceptSocket();
NetworkStream nstream=new NetworkStream(socket);
BinaryReader reader=new BinaryReader(nstream);
int k=0;
k=reader.ReadInt32();
byte[] ba=reader.ReadBytes(k);
MemoryStream ms=new MemoryStream(ba);
Bitmap bmp = (Bitmap)System.Drawing.Bitmap.FromStream(ms);
this.pictureBox1.Image = bmp;

//this code is on server side but the problem is still the same.
On client side bitmap is being convert into bytes and on server side we must convert them back to bitmap.
Thank's
