Salut Guillaume,

You may want to prefer using a Grid instead of a ListBox. Beginning with VFP 8 you can mimic a ListBox with AllowCellSelection=.F. and HighlightStyle=2

Listboxes are not really designed to support that many items.

>You can scroll as much as you want.
>No, make an index on the cursor ex. index on c_Field tag c_Field
>Now, if you try to scroll with the listbox, you'll get an Internal Consistency error.
