WinSock Error

I am trying to learn how to use WinSock. Logically I think it is easy, you just need to set up the ports and the rest and things should work (right?)

Anyway, I send a message through a port, I get this message (Run-time error 40006 'Wrong protocol or connection state for the requested transaction or request'. What does this mean? Please help!

Something on the side:
I'm trying to use this instead of DCOM, if you could give a hand with DCOM, I would gladly accept. Thanks.

did you set the protocol property? it must be set to either UDP or TCP in order to work...

If you are using the correct protocol then you are most likely sending data before the connection has completed. Check the control's .State property before envoking the .SendData method. .State should be = sckConnected = 7

It does not related to the protocol used. In Winsock this error normally mean your port is either closed or your have't initialize (Open) the port when you try to send something out from the port.

So you should check the state before you send anything out.

Code:

---

    If Winsock1.State = sckConnected Then
        Winsock1.SendData "Testing..."
    Else
        MsgBox "Invalid winsock state!"
    End If

Use the WinSock SendData method with in the connect event.. this insures you have a connection.

That's fine if you want to send 1 message and be done with it.

If you need to exchange multiple messages, you want to establish a persistant connection. That means the SendData should be elsewhere so that you can call it when you need to send a message. The State should be checked before each call to make certain that the connection is still up.
