Add the class library that you saved the grid class to to the form controls tool bar but clicking on the ViewClasses button and selecting add. Locate the grid class on the tool bar and drop it on the form.

Rejected? How? Do you have the controlSource for the column set before you do the addobject? Oh, I think you also have to set .CheckBox.Visible = .T. As I recall, objects added with AddObject are not visible until you explicitly set their visible property.
