I've been having difficulty persuading Visual FoxPro comboboxes to behave rationally. I have a KeyPress event looking for ENTER to execute some code to populate the drop down. I also have an Interactive Change and/or a Click event to tell me when a selection from the dropdown is made.

Problem is, the KeyPress event works fine, but if I use Interactive Change or Click event I can never tell when an ENTER is done with the list dropped down or not. If is is hit when the drop down is on, I want to select the value entered on, other wise I want to us the display value.

Bizzarely enough using a the ListIndex often returns greater than zero when new values are being entered, when I had assumed it would be set to zero when you started tying characters not seen in the drop down.

What is the standard method of handling combobox entry?

Thanks in advance
