WPF: Is there a possibility to "route" ordinary mouse events to touch events in Windows 7

I'm currently developing a touch screen application using C# (.NET 4.0) and WPF for Windows 7. My problem is that the driver of the touch screen I have available at the moment only generates mouse events. (The manufacturer unfortunately does not provide a genuine Windows 7 driver) So, currently I'm not able to do tests pro开发者_开发百科perly.

Is there a generic way to tell Windows 7 that a certain device is supposed to be a touch device (although this -- of course -- could only provide single touch events)?

Check this. http://blakenui.codeplex.com/. There is a MouseTouchDevice.cs file that looks like this. It converts normal mouse events to Manipulation events.

I am hoping this is what you are looking for.

You would need to rewrite the mouse driver to act like a touch device to do this. A simpler workaround would be to get a device like the Wacom Bamboo Touch? It's a real touch device (not a touch screen).
