winsock Problem

[razzaj]

I have a server Application that takes connections on Port X lets say.

When I am terminating the Application I am executing the following code :

 


       Winsock1(0).Close

and I am looping waiting for the winsock to close

WHen I try to run the application Again. It always gives me the error Port in USe....

I have to restart for it to clear the port ... Any ideas How I can explicitely free the Port I am connecting to ?

I posted an answer to your post in the other section, but after reading this description of the problem I'm not sure if your problem is on the client side or the server side.

If it is the client, are you using the same local port everytime? If so, don't assign a port. Let the system assign one for you. It won't use any that are busy.

Winsock:

Im required to write a simple program using winsock to accept a tcp message on a certain port, log it, then fire this message out on another port.

Any ideas?? Please supply some form of code as ive never used winsock before.........examples would be greatly appreciated

It sounds like you will be receiving messages from one program and routing them to another. It this correct?

If so, your program will need at least 2 winsock controls. One will listen for connections from the sending program, connect and then accept the messages. The other will connect to the receiving program and forward the messages after they are received on the other winsock control.

I uploaded an example client/server app a couple months ago. The file is CS.ZIP and the link can be found in the post http://forums.vb-world.net/showthrea...threadid=71122

There are a lot of comments in the code to help you understand what is happening. It also describes things to be aware of when sending UDTs.

Many Thanks for your response.

I don't know why it won't work. I had to search for messages that I posted to find it. Actually, I found another post in which I had posted the same link. That worked for me, so I copied the url and pasted it into my previous reply to you.

I also noticed that I got an error when I tried to download the file. There is a problem with that. I don't know what the problem is. I have the morning off and the file is on my office workstation. I will send you the file after lunch. I think I'll send it to myself also, so I'll have it at home.
