Hi Bruce

The link to the cs.zip attachment you provided does not open "Page cannot be displayed"....would it be possible for you to send me the attachment to my hotmail account [email protected]

Many Thanks for your response.

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

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/showthre...&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.
