Dan,

I had a bugger of a time with 'Internal Error 34623' on an integrated
mapping project I did with VB and MapInfo. The reason this error is
generated is because a window handle is not being passed correctly or in my
case, in a timely fashion, inside MapInfo. What I had to do was to write a
piece of code to delay the closing of a window for 2 seconds to let MI catch
up with the rest of the world.

This is a known problem to the folks at MapInfo, but there seems to be
nothing more than an internal memo documenting it. I've attached the text of
this memo at the end of this email.

Hope this helps!

*************************** MapInfo Memo *********************************

Issue: What is Internal Error 34623?

Discussion:
A user is sending
objMapInfo.Do "close table states"    to MI from VB5, and gets this error.
If he sends
str = "close table states"
objMapInfo.Do str
then it works OK.

Do you know what this error means.  I assume MI is generating it.

Conclusion:
The error means that an invalid WINDOW handle has been passed somewhere.
