Hi Joe,
Here are some examples using different controls sources.
There is also the Sorted property that can be used.
The Sorted property is only available if the RowSourceType property is set
to 0 (None) or 1 (Value).
HTH,
Tracy

Subject: Combo box issues
I am looking for a way to have a combo box display its dropdown
programmatically. I want to do this to make it obvious that the user needs
to make a choice. I have read that 'thisform.combobox.dropdown()' should
do the trick but the form comes up with the proper information in the
dropdown which can only be seen after clicking the control.
Another less important feature would be a way to control the position of
the list of choices when the dropdown is accessed.
Any help will be appreciated,
Joe
