getting extra excel instance when controlling from access VBA

G

Guest

I am writing a program in Access VBA to create an excel spreadsheet, import
data into it from Access queries, and format it. It works fine until I tried
putting a drop down list into it for data validation. Even that works, but I
am left with an instance of Excel in the task manager even though the
workbook has been closed and both the xlapp and xlworkbook has been set to
nothing. I can't even terminate the instance using a version of this code
that has only the get object parts and the close and set to nothing parts. It
recogizes that excel is open, grabs it; then when you do application.quit and
set to nothing, it just sits there in the task manager. Nothing seems to stop
it. Variations of this have been plaguing me for days. Please help.

Duane,

Just looking at the first portion of your code...
I have made some changes that could help. (untested)
The workbook and worksheet objects are set to nothing
before quitting the application.
A separate object reference is used for the worksheet.
Use of the "With" construct was eliminated.
Eliminated references to anything "Active".

Regards,
Jim Cone
