TcpClient in Managed C++

[KimGonzales]

Hey guys,

When I run this managed code snippet:
listener = gcnew TcpListener(MyIPAddress, ServerPort);
listener->Start();
MyTcpClient^ mclient; //TcpClient public
TcpClient^ aux = listener->AcceptTcpClient();
mclient = static_cast<MyTcpClient^>(aux);

I get the following error:
"System error: cross-thread operation not valid: Control 'listBox1' accessed from a thread other the thread it was created on."
Please, I just can´t understand what´s going on!

This really looks interesting, because your code fragment doesn't contain listBox1.
Generally, cross-thread operations on Windows Forms controls are not allowed, they should be serialized using Control.BeginInvoke and Control.Invoke methods.
