I have a routine to transfer data between excel and autocad. My
routine starts in Autocad and is supposed to go to the open excel file,
extract the numbers and place the numbers in Autocad. Sometimes it
will bypass the open excel file and will open a new instance of excel
that has no worksheet. How can I prevent this from happening.

Mary,
Change your code, but as you didn't post any, I can help you.

Mary,
Looks like GetObject is failing because there is no instance of Excel
running, so you are creating a new empty instance, even though that code is
commented out in your sample.
Also, whilst not the cause your problem, it would be better to use something
like "XLApp" instead of "excel" for the variable name.

Assuming ACAD VBA behaves the same as in Office, this line really means
nothing:
If Err<0 Then
because you have no "On Error Resume Next" before GetObject. So if there is
an error, it will not be handled.

So basically your is code is working (after you add "On Error Resume Next").
But because you need to work with the current XL file, you should exit your
code if GetObject fails, because you have nothing to work with.
Also, you do know that if you have more than 1 instance of Excel running,
GetObject will give access to 1 instance essentially at random. So you may
not get the reference to workbook you desire.
