I have a customer for whom DDE is failing on some workstations after deploying to 64bit as 32bit.

They're using DDE only to communicate between PowerBuilder-developed applications.

I'm going through the checklist of UAC, log jam of splwow64.exe or other DDE users, etc.

 

In the meantime I'm determining time needed to replace these PowerBuilder apps' DDE usage to communicate with each other compared to time needed for a "fix".

I'm tempted to shoot from the hip and use TCP/IP (don't want to broadcast via UDP), but I want to ask you folks to check me on this.

I don't want to have the TCP/IP hammer in hand and have everything look like a nail (if this an apt simile).

 

What is the least time-intensive way that you've historically used to replace DDE comms?

 

Thank you.
