示例1: CompareRanges

' Specify the control type we're looking for, in this case 'Document'
Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)
' target --> The root AutomationElement.
Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)
Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)
If (textpatternPattern Is Nothing) Then

Return Nothing
End If
