Colin,

I get the same sequence of events either way. It also clears the Value of the cbo when I use the up/down arrow in the cbo, it doesn't when I tab. Altering the Style of the cbo doesn't seem to be such a good idea. The subclass won't ever display the selected value chosen from the dropped list.

It's rather revealing to see mycombo.text1, it looks like VFP is internally building the cbo from a button and a textbox. And the nShiftAltCtrl value of 8 doesn't make sense according the the help file.

You may have to just stop messing around with Style and set a flag to know how to handle the up/down arrow keys.

>I encountered an odd problem with this solution. If I put this code directly into the combobox on the form it works fine. If I put this code into a combobox class used on a form the UPARROW works fine but the DNARROW blanks out the value. I turned on event tracking for both and discovered the following:
>

>myform.mycombo.Valid()
>myform.mycombo.text1.Destroy()
