The result is that the practical time in order to create a ComboBox
( with rowsource empty ) is medium 10 times the time necessary to create a textBox.

Ok, ComboBox and Spinner is composite object, but 10 times it is difficult to comprise.

Strangely, for a ListBox the time is inferior.

Strangely, now editbox is more fast of textBox.

The optimal Fox Team job carried out from the VFP6 to the VFP7 ( gain 5 times on more control) and now to the VFP8 ( gain 10 times on grid !!! ) makes us to hope that also for Spinner and the ComboBox the time comes reduced.
