if (controlTypeNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else  
{
    controlTypeId1 = controlTypeNoDefault as ControlType;
}

Dim controlTypeId1 As ControlType
Dim controlTypeNoDefault As Object = _
    autoElement.GetCurrentPropertyValue(AutomationElement.ControlTypeProperty, True)
If controlTypeNoDefault Is AutomationElement.NotSupported Then
