I am trying to write a data aquisition control. The design I am looking for is a server computer on the internet with a listening socket and has capability to service many clients. The services it is to provide is port 80 web page service and port n (maybe 8000) to service my real time control. This is what I want: The way I want a typical client computer to work is instantiate "one" DLL which will talk realtime protocol to the server. Then the user will pull up a webpage with many activex (or java beans, whichever the case may be) controls on it which will talk to the "one" DLL. This is what I have: Each activex control grabs his own socket to talk to the server, this has proven to be wastefull. Is my "want" client scenario even possible. I am using Visual C++ right now, and have trudged through all the MSDN sample apps, and only have found a minimal chatter/chatsvr where I was able to ascertain some of the tricks necessary to do the communication ( I found CAsyncSockets to be more useful). If anyone knows of some good sample code on the net, I would be much appreciative, or even a good link to a tech article on how to do this. the main thing I am interested in the the communication between the one and only DLL and the OCX instances. Can I use a static function to accomplish this? Thanks for any help. Richard
