AutomationProperty

Examples

The following example retrieves the current value of the property. The default value is returned if the element does not provide one.

int nativeHandle = (int)
    autoElement.GetCurrentPropertyValue(AutomationElement.NativeWindowHandleProperty);

Dim nativeHandle As Integer = _
    CInt(autoElement.GetCurrentPropertyValue(AutomationElement.NativeWindowHandleProperty))

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.

int nativeHandle1;
object nativeHandleNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.NativeWindowHandleProperty, true);
if (nativeHandleNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    nativeHandle1 = (int)nativeHandleNoDefault;
}

Dim nativeHandle1 As Integer
Dim nativeHandleNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.NativeWindowHandleProperty, True)
If nativeHandleNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    nativeHandle1 = CInt(nativeHandleNoDefault)
End If
