You do have Get and Let properties for the controls, right? The properties aren't exposed (you can't see them from the project) without a Get routine and you can't set them from the project without a Let routine.

In the code for the control, click on Tools/Procedure Attributes ...

Find the control whose description you want showing in the project (in the Name listbox). Click on Advanced. Make sure that "Hide this member" and "Don't show in Property Browser" aren't checked. If you want a description showing in the description area, put it into the "Description" textbox.
