how to hide flick pointer in WPF?

Question

I reference this article

How to handle window message in WPF? http://stackoverflow.com/questions/624367/how-to-handle-wndproc-messages-in-wpf/624424

And can get a message(WM_TABLET_QUERYSYSTEMGESTURESTATUS) from touch screen.

But more than that, I want to return TABLET_DISABLE_TOUCHUI_FORCEOFF | TABLET_DISABLE_FILCKS to hide flick pointers.

It's not work in WPF project, but it's work in C# form project.

Does anyone know how to hide flick pointer in WPF?
