[AccessD] Excel object behavior

Shamil,

Well, I don't know if I have a problem or not.  I was trying to troubleshoot a user complaint, and noticed that they had a ghost instance of Excel.  When I stepped through the code, I noticed that the timing of the "death" of the instance didn't coincide with the setting of the final pointer to Nothing.  When I did a simple test procedure that started and terminated an Excel instance, I noticed that the instance died immediately upon setting it to nothing.  So it leads me to think that the user's complaint might be related to the way the objects are being terminated.  I don't understand much about that (though, thanks to your help I now understand more) so I raised the question to the experts.

Thanks again for taking time to respond to my musings . . .

Don

Don,

I'm not sure I understand what is the issue? - if you tell that "the
instance DOES go away" but in the same time you tell that you're
"overlooking a pointer somewhere that needs to be set to Nothing."...

I mean if MS Excel instance does go away - that's OK IMO, and everybody
should be happy even without setting all the pointers to nothing :)...

What am I missing?

Thank you.

Shamil,

Thanks for the detailed explanation.  And yes, I was watching the processes
tab of the task manager.  I was careful to make sure that there were no
Excel instances present before running the procedure.  As I step through the
part of the code that cleans up (closing workbooks, quitting Excel, setting
pointers to Nothing, etc.) the instance remains on the processes list.  Only
upon execution of the "Exit Function" line of the procedure does the
instance disappear - but the instance DOES go away, it doesn't remain a
ghost.

I suspect that I'm overlooking a pointer somewhere that needs to be set to
Nothing.  I thought I got them all, but maybe not . . .

Don
