Winsock Control Help

Thanks in advance for the help.

I'm trying to build messaging into my app using the Winsock control and
there is something that I don't quite understand.

I need each instance of the app to act as both a client and a server so that
it can receive messages from anywhere and so that it can send messages to
anywhere. Do I need two controls? Do I listen and send on different ports?

Has anyone ever built this type of app using this control?

Thanks,
Jeff

Hi Jeff:

I am not sure if this example is what you are looking for, but we have this
article:
For using Winsock:

I hope this helps.

Thanks Lee,

Actually I already had that and it was playing with that which led me to my
question.

It appears that the answer is that I need to use UDP protocal and not TCP
protocol. UDP does not have clients or servers and connections are not
required.

It is a simpler (judging by the QuickBasic code) protocol to write for but
it will make debugging my application more difficult as it will require two
separate machine with two distinct name or IP address in order to test.

Thanks again,
Jeff

Neil,

Thanks. It is a good article. It does not really address the type of coding
that you need to do to use UDP but it is very comprehensive in going over
what you need to do for TCP protocol. There are also things like the
Autoyeild property that I simply wouldn't have thought of without this
article.

What I am trying to do is have each app be able to send and receive
messages. This requires a connectionless protocol such as UDP.

Once I get some working code I'd be happy to post or share it.

Thanks again,
Jeff
