>Hi, Dear All,
> When I use a logic field as the combo box control source, it always get out some error message "Error:combo-value data type mismatch. Can't bound the object combo" while init the object combo box in runtime. Is that a bug of VFP and how can avoid it ? Thanks anyway!:)

No, it isn't a bug. You can't bind a combo box to a logical field. Use a check box instead .. that's what it's for.
