PRB: Apply Button on Custom OCX Property Page Always Disabled

     Changed = True
				

MORE INFORMATION

The Visual Basic IDE or run-time system controls the state of the Apply Button on your custom property pages. In order to tell Visual Basic that the user has edited one or more properties on a property page, you must set the PropertyPage object's Changed property to True. Because there is no way to know which property a user might decide to change, you must do this for every property displayed on the page.

The following code snippet illustrates using the Changed property in property page code:

      Private Sub ControlCaption_Changed()
        Changed = True
      End Sub

      Private Sub ApplyChanges()
      Dim X As Variant
        For Each X In SelectedControls
          X.Caption = ControlCaption.Text
        Next X
      End Sub
				

This process can be simplified by using the Property Page Wizard from the Visual Basic Add-Ins menu.
