Mark;

I have to agree with you and tried this back in the VFP 3.0 days. It is not stable. I recall a statement made about combo boxes in 1995, "There are ten ways to use a control source with a combo box. Three of them work"! :)

>IMHO, using a private memvar as the ControlSource is a bad idea. I would add a property to the combo and use that property as the ControlSource. If you need something more globally visible, add a property to your global app object and use that.

>For further stability, I prefer a SQL statement or an array as the RowSourceType for the array. If I use an array, I use an array property of the combo, which I have already added to my combo subclass.

>I have an example of a combo class in the UT downloads that can also be used to add new records to the source table if the combo is used as a dropdown combo.

>>I have a combo box on a form that has two columns showing the contents of a foreign table. The first column is the description, the second is the code, which is numeric. The BoundColumn property is set to 2 and the BoundTo property is set to True to get it bind. The ControlSource is a private memory variable. The row source is an Alias.

>>Fine so far. It accepts the selection that I make. However, it won't show the description (column 1) until I save the changes. 'Ah ha' I hear you cry, you must set DisplayValue to 1 to force that column to be shown....'Ah ha ughhhh' I reply...done it..and seen some of the weirdest behaviour in a language I've seen since I used DataEase years ago. Display value works...once! and then it doesn't. If I modify the form in any way it sets the DisplayValue to 0 and I'm back to square one.

>>I understand from my colleague, who has been using FoxPro for some years, that combo boxes are a bit weird when bound. How the hell else do you use them??? He's just showed me his usual way of using cb's and it's stoneage...

>>Please tell me there is a simple work around...my sanity and productivity depends on it.
