I'd like to talk with someone who has some knowledge of programming a DDE
server. All I need to do is write a very small no-frills DDE sever - Oh,
USING DDEML.

I've already done this, and I can get data from it using Excel and another
program. But there is this one piece of software that I need to interface
with and everything locks up when I try to link up my DDE server to this
program. I'm using Petzold's WIN95 book, and I used HIS DDE server example
program with this program and everything still locked up.

I'm curious about certain settings for the DDE sever that maybe would cause
problems with this one particular program. I've just introduced myself to
DDE and I'm a new Windows95 programmer.

Any help is greatly appreciated. It's a very simple program.

If possible, please tag an e-mail reply.

Thanks again.

Sounds like you are freeing some Global blocks still in use.
What XTYP are you using? How about some code?

Oh.. if you are a Windows95 programmer in Redmond then You should know..
Hehe, you probably mean Win32c or ever Win32 user and C(++) programmer? :)

As for what could cause the problem there are several possibilities. One could
be that you aren't answering all messages you are supposed to in the
negotiation. I suppose you haven't used anything but the simple System
link with Excel.. If you post/email some code segments we might be able to
help.
