Hi all,
I've been using DeTransfer for a while now, and I use DDE commands to send data to another software package that does all of my logic and fancy GUI stuff.

However I've noticed something funny on of my systems - after a while of acquiring data, slowly but surely, the DDE data gets corrupted. The channel names (and DDE modifiers) somehow leak into the data. So say I want to read the data of DDE channel "&!Chan1". Normally I'd get a response like "0.52" or something like that. Instead, after this corruption happens, the data returns will become something like "0.52&!Chan2".

Deleting the data from the DDE window temporarily fixes the problem, however it eventually comes back. Have you guys seen this?
Cheers,

Good morning KevN,

No I haven't seen it and unfortunately DDE is very old technology and no longer supported by Windows (Remove in Windows Vista) so there will be little we can do to assist.

Cheers

I think I found what was causing the problem here actually. It seems to have something to do with the fact that I was using a usb-rs232 converter, and the converter I'm using doesn't seem to be passing on XON/XOFF commands to the datataker. The lack of flow control was what was causing the problems mentioned.

The more you know I guess...

Hi Kev,

Thanks for the feed back. That would have been a hard one to diagnose from your post.

Keep breaking things.

Cheers

Roger
