Hello Excel programming gurus (and others),

Assume I have a workbook, call it WB1, open. Then assume that
I open a second workbook (WB2).

Workbook WB2 has nothing in it but data. (It has nothing which
in the way of macros or code of any kind.) Workbook WB1 however
has a large number of macros which will be used to organize,
scan, and reformat the data contained in Workbook WB2.

My question is, is there a way, using macros and code which
is contained in WB1, to capture when WB2 is opened and perform
some set of tasks? I haven't been able to successfully get
the "On_Open" macro in WB1 to fire when I open WB2. (FWIW,
the WB2 names won't always be the same so I can't hardcode
in a specific name to look for.)

Suggestions of how I might be able to do this?

Many thanks, in advance, for any ideas or suggestions.

David
