Hi NG

I have populated a listbox by using listbox1.rowsource
There are many similar entries in the listbox.

The user can then an entry and the listbox_change() callback is called. In
this callback I would like to be able to extract the rownumber of the
users
selection e.g. rownumber == 3 if the user chooses row 3 in the listbox.
The
reason that I do not use Listbox.value is as i mentioned before the many
similar entries in the listbox.

Regards
Mark
