if (labelerNoDefault == AutomationElement.NotSupported)
{
 // TODO Handle the case where you do not wish to proceed using the default value.

 labeler1 = labelerNoDefault as AutomationElement;

Dim labeler1 As AutomationElement
Dim labelerNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.LabeledByProperty, True)
