Hi--
On a Windows Form, I have assigned accelerator keys to the controls by
setting my tab order, and using '&' in front of the relevant character in
the label preceeding the control.

I have an .aspx with some controls that are created dynamically. The
items are populated into the box by setting the DataSource-property to

I'm trying to append data to an existing Excel file (.xls).
I've managed to find a way to write data to an Excel sheet but when I try to
do the same to a file that already contains data it saves it as a new file
without that data.

At first, it's easy to say (have a policy) that we'll hard-code for
statuscode='ACT' (or maybe instead statuscode <> 'INA') but I think that
pigeonholes us and would cause limitations.
Example: We want to develop an Employee search screen.  Obviously, we don't
