First of all, there no such limitation in the .NET Socket implementation : the actual code beinh Receive() is in fact a direct Winsock2 recv() function call, and it passes your buffer directly, not an intermediate buffer. I can see an error in your code : in your loop, you are Accepting a new socket instance at each iteration. :confused: Usually, you accept a socket once, and then loop with Receive.

Thanks Heath, Is there an easy way to check for the active control index? DB

I don't want the console to display at all, I just want all output to be directed to a textbox or something. This [^] article explains exactly how it is done in C++, I was just hoping for a C# version of it that is more simplified.
