I don’t understand the error, I mean it’s the same code as on your windows forms application, why is this exception in the ReceiveData method being thrown?

Any clue would be awsome…

I failed at trying to add a new section to the packet, which sends the names to the client :\

Why did you fail – what have you tried so far?

Would you mind giving me an insight on how to send a list of all the users currently connected to the clients? I tried but failed.

I have noticed that an error occurs on sending a large array of bytes … I mean a VERY large array … something that reaches multiple kilobytes … I dont what exactly limits the buffer size …

So, is there a method to send this large array by adjusting the original chat program code instead of the one you sent last time? (I was able to adjust the original code, but I am still limited by the allowed buffer size) …

Sorry for my continuous questions

To send the file:
// Create stream to load file
FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read);
// Go to beginning of file
fs.Position = 0;
// Setup temporary buffer
byte[] tmpBuf = new byte[1024 * 1024];
while (fs.Position < fs.Length)
{
// Loop until we reach the end of file
int len = fs.Read(tmpBuf, 0, tmpBuf.Length);
// Write file to stream
dataStream.Write(tmpBuf, 0, len);
}
// Clean up
fs.Close();

To receive the file:
fileStream = new FileStream(file, FileMode.Append);
readLenth = 0;
while ((readLenth < dataSize) && !exitLoop)
{
// Read data from socket
bytesReceived = socket.Receive(dataBuffer, 0, dataBuffer.Length, SocketFlags.None);
// Exit loop if nothing was received
if (bytesReceived == 0)
{
exitLoop = true;
break;
}
readLenth += bytesReceived;
// Write received data to filestream
fileStream.Write(dataBuffer, 0, bytesReceived);
}
// Close filestream
socketData.FileStream.Close();

Hope that helps
