>I am just trying to get the native combobox to work in a more typical setting, say a dropdown list of part numbers and descriptions for several hundred items at most. Probably a pretty common scenario for invoices.

It just frustrates me that after all the versions of VFP (3 thru 9), that such an important native class does not work as the masses would expect... And that I just happen to pick it on the very forst form I try to design as a newbie :(
In VFP 9 SP1 I created a combo with these values
"Aaaaaa"
"Abaaaa"
"Acaaaa"
"Adaaaa"
It does not close the value. So all you gotta do is upgrade! :)
However, when the list opens, hitting Ac changes the displayvalue, but doesn't move the highlight down the list. The highlight stays where the mouse is. I'm not sure that's intended.

>>Frankly the combo box is not the greatest control. It's often abused. How do I put 400,000 customers in a combobox is a far too frequently asked question.
