Richard is asking about DDE and Wonderware, wow that takes me back, I used to do a lot of work with WonderWare's Intouch product, along with a wide variety of other SCADA platforms and PLC's. IIRC Wonderware developed something called FastDDE, which MSFT eventually licensed from them, to become the DDE we all know and love today. I'm surprised its still using DDE, they were trying to kill it off and switch to OPC when I left the process control industry back in '97
