property PropertiesList.ShowRestricted as Boolean

Retrieves or sets a value that indicates whether the properties browse displays the restricted members.

TypeDescription
Boolean A boolean expression that indicates whether the properties browse displays the restricted members.

Use the ShowRestricted property to include restricted members. Changing the ShowPropertyPages at runtime invokes refreshing the control. 

Here's a sample that shows how to include only hidden members:

Private Sub PropertiesList1_IncludeProperty(ByVal Property As EXPROPERTIESLISTLibCtl.IProperty, Cancel As Boolean)
    Cancel = Not (Property.Flags And &H40) = &H40
End Sub
