I'll try a version calling Excel via DDE as time permits.
It's not a show stopper, I just have to be careful.
Thanks,
Ray

I can see no obvious leaks in the dde code. It is possible the problem is at the "other end" of the conversation? If it possible to create a repro case using Python code at both ends?

- Subject: [python-win32] dde.pyd always dies after exactly 16378 Requests
- In the attached .py test, I start an external program that provides data access via DDE.
- create a server
- do a number of CreateConversation-s, one for each channel
- make connections
- do lots of .Request on the connections
- I tried just one channel, one connection, still 16378, so it seems to be the total number of requests, irrespective of connections/Conversations.
- Do I need to periodically clean up resources somehow?
- The docs at Activestate are a bit sparse, and I could not find the answer from MSDN.com:
- "The maximum number of DDE conversations that can be open simultaneously is determined by Microsoft Windows and your computer's memory and resources. If the conversation can't be initiated because application isn't running or doesn't recognize topic, or if the maximum number of conversations has already been reached, the DDE function returns a Null. "
- But, conversations is not the issue.
- Am I doing DDE in a fundamentally inefficient manner?
- Would using 'CreateServerSystemTopic', 'CreateStringItem', 'CreateTopic' help at all?
- When I run this script (or similar, counting requests), it always ends up like this:
- C:\python ddeclient_tst.py
- ...
- 16362 same
- 16363
- 16364
- 16365
- 16366
- 16367
- 16368
- 16369
- 16370
- 16371 same
- 16372
- 16373
- 16374
- 16375
- 16376
- 16377
- 16378 <---- dies here with Windows error

- I could shut down the server and reconnect it all, but that takes significant time.
