' elementList is an AutomationElement.
Dim helpString As String = _
    CStr(elementList.GetCurrentPropertyValue(AutomationElement.HelpTextProperty))

The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

// elementList is an AutomationElement.
object help = elementList.GetCurrentPropertyValue(AutomationElement.HelpTextProperty, true);
if (help == AutomationElement.NotSupported)
{
    help = "No help available";
}
string helpText = (string)help;

' elementList is an AutomationElement.
Dim help As Object = elementList.GetCurrentPropertyValue(AutomationElement.HelpTextProperty, True)
If help Is AutomationElement.NotSupported Then
    help = "No help available"
End If
Dim helpText As String = CStr(help)
