Заметки

The AttachedControl or Handle property must be set before the InkOverlay object can be enabled.

If the InkOverlay object is attached to a window handle, setting this property attaches the InkOverlay object to a control and clears the Handle property.

Примечание.
The InkOverlay must be disabled before setting this property. To disable the InkOverlay, set the Enabled property to false. You can then set this property and re-enable the object by setting the Enabled property to true.

If you use the AttachedControl property and the Handle property in your application, you will get a security exception when you run the application in the Internet zone. This is because the Handle property is not valid in the partial trust environment of the Internet zone, so the Tablet PC operating system reverts to the AttachedControl property.

Примеры

In this example, the AttachedControl property is used to invalidate the control that is used by the InkOverlay object.

' Note: mInkOverlay was instantiated via: new InkOverlay(control)
' not via: new InkOverlay(control.Handle) - this .ctor does not set AttachedControl
mInkOverlay.AttachedControl.Invalidate()

// Note: mInkOverlay was instantiated via: new InkOverlay(control)
// not via: new InkOverlay(control.Handle) - this .ctor does not set AttachedControl
mInkOverlay.AttachedControl.Invalidate();
