Winsock Error Handling Vb6
Next wire up the Send button: Private Sub cmdSend_Click() sockMain.SendData txtSend.Text End Sub Again very simple, all we do is Winsock control to send the data we want it to.

Thank you in advance. Another thought occurred to me, for some reason I think I remember there being issues with using the localhost address... The next piece of code that we’ll add will display the server’s IP address in the lblIP. I'm still bothered by that Winsock.Close in the server.

like maybe you are causing sckWouldBlock(10035), sckMsgTooBig(10040), or sckNoBufferSpace(10055).

Along with the Winsock State Constants you can easily determine what ‘state’ the control is in. When you come back to your code you may have forgotten typical errors that occurred and will be left having to put in very generic code.

This will start the server listening. In those cases you should be periodically checking the connection for all of the clients from the server and closing any connections that do not respond to some kind of ping
Unfortunately most of the errors that get routed here will result in you having to gracefully shutdown the multi-player system. Why don't you in the send buttons click event have it send the text to the other person and then simply append that text to your text box?

The root of the problem is that the socket that is sending data is closed before the socket that is receiving the data can process the receipt and the close of NO PROBLEM.. Right now the control has prepared itself for a connection from the client computer. Normally you would create a new Visual Basic program just for the dedicated server, but to make things easier we are just going to create a second form.
I am going to start capturing data with Wireshark, but I'd like to know if I'm trying to do something fundamentally wrong. However, most clients vehemently deny doing anything of the sort. Can't I just use it as [code] With Winsock1(intNext) .Accept(requestID) .SendData("Hello from server") End With[/Code]One more small doubt, I have read a few tutorials on winsock programing and all of them
