WindowPattern.Pattern Field

Identifies the WindowPattern control pattern.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)
'Declaration
Public Shared ReadOnly Pattern As AutomationPattern

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in WindowPatternIdentifiers.

The pattern identifier is passed to methods such as GetCurrentPattern to retrieve the control pattern of interest from the specified AutomationElement.

In the following example, a WindowPattern control pattern is obtained from an AutomationElement.

'''------------------------------------------------------------------------ 
''' <summary> 
''' Obtains a WindowPattern control pattern from an automation element. 
''' </summary> 
''' <param name="targetControl"> 
''' The automation element of interest. 
''' </param> 
''' <returns> 
''' A WindowPattern object. 
''' </returns> 
'''------------------------------------------------------------------------ 
Private Function GetWindowPattern(ByVal targetControl As AutomationElement) As WindowPattern
    Dim windowPattern As WindowPattern = Nothing 

    Try
        windowPattern = DirectCast( _
        targetControl.GetCurrentPattern(windowPattern.Pattern), _
        WindowPattern)
    Catch 
        ' object doesn't support the WindowPattern control pattern 
        Return Nothing 
    End Try 
    ' Make sure the element is usable. 
    If False = windowPattern.WaitForInputIdle(10000) Then 
        ' Object not responding in a timely manner 
        Return Nothing 
    End If 
    Return windowPattern
End Function 'GetWindowPattern
