Socket.Receive method. It blocks the UI

[Diego F]

Hello. I'm using the socket class in an application and I use socket.receive to wait for data. The problem is that the interface gets locked while the receive method is executing. I want to see the interface so the user knows what's happening at any time. Is that possible?

Regards, Diego F.

Hello, Put that socket code in diffrent thread..or it will block th UI until it receives the connection.. Regards :rose:, Nishu

I found a problem with that. Now, I can't access the UI controls, as they are in other thread. I get an execution exception. How can I solve that?

Regards, Diego F.

Youc can also use BeginReceive and EndReceive to achieve the same. This moves the thread handling to the Socket class. If you are doing lots of operations then you might want to do the thread handling yourself.

You can use the Invoke method on the control or form to run the method you are calling on the correct thread.

You might be getting the cross-thread exception. try this // UI class functions public void UpdateMenus() { if (this.InvokeRequired) { this.Invoke(new UpdateMenusDelegate(UpdateMenus), new object[] { sender, e }); return; } // continue with your code }
