I have multiple controls that I create/load on a form based on user interaction using Load i.e,

Load optCriteria(Index)
With optCriteria(Index)
.TOP = optCriteria(Index - 1).TOP + BLOCK_TOP_OFFSET
.Visible = True
.Width = optCriteria(0).Width
.Container = Me.picAll
.ZOrder 0
.Left = BLOCK_LEFT_OFFSET
End With

Do he controls that are loaded need to be Unload'ed when the form is Unload'ed? If so, what event should this be done in?

Thanks
