When you try to set the MatchEntry property of a DBCombo control to”1 – Extended Matching”(at run time or design time), VB may reportthat the “Property is read-only.” The problem is that ExtendedMatching may be used only with DBCombos whose Style is “2 – DropdownList.” Change the Style property accordingly and the error will disappear(if only Microsoft had thought to mention that in the documentation).
