There is a VB6 application that ships with the DDE server that shows how to use the DDE Server to read & write PLC data via the DDE interface, and one that shows the same process only it is using the OPC interface.

But I suspect that this is not what you're asking about. Are you looking for an ActiveX control that implements the DDE interface? If so, we don't have one of those. I've had several folks through the years ask for help in creating one in exchange for their providing us a copy of the completed work, but so far no one has followed through and given us a copy of the control to make available.

It would be or that made a ACTIVEX or similar to be able to integrate dde in the projects and thus to simplify the final installation of sotware in the clients. Besides to control better and to limit the DDE since he would not allow himself that the client changes the configurations of the DDE. We have problems with this, since the final clients have access to the configurations of the DDE and also they can deactivate it when they want causing that our application falls.  :'(

There is possibility of in the future develop this DDE SERVER in ACTIVEX or similar format?  ;D

 :o He would be perfect

Greetings and Thanks

Right now, we have no plans to do much of anything to the DDE Server.

There's not much we can do to the existing product without some extensive rework because we would first need to build it with some new DDE/OPC provider because the package we used is no longer supported.
