Thank you for these great tips and examples.

I have a good Winsock example:

depends on what you are doing with the dde.  there is no drop-in replacement.  microsoft is trying to get rid of it.

you could simply send a message to your app when you want it to do something.  If you need to send data or instructions, you could put them into the registry and then read it in your app.  that is similar to what chris suggested in using sockets, except this method there would be no response and no follow up.

Hi Thierry;

  All Deprecated means is that they are no longer enhancing that feature but it's still there. What I did find in 2022 GA though is that only 32bit DDE worked.

   A good replacement though could be TCPIP (WinSock).
