Attempts to close the current window.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

Public Sub Close


The control is unable to perform the requested action.


When the control is no longer available.

When called on a split pane control, this method will close the pane and remove the associated split. This method may also close all other panes depending on implementation.

In the following example, a WindowPattern control pattern is obtained from an AutomationElement and is subsequently used to close the AutomationElement.

Private Function GetWindowPattern(ByVal targetControl As AutomationElement) As WindowPattern
    Dim windowPattern As WindowPattern = Nothing 

        windowPattern = DirectCast( _
        targetControl.GetCurrentPattern(windowPattern.Pattern), _
        ' 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
