How can i programmatically manipulate the Windows 7 on-screen keyboard osk: Move, Resize, Remove Titlebar/Caption

I'm working on a WPF app where i want to display the built-in windows 7 onscreen keyboard in a 'always there' manner. So i want to:

1. Move i开发者_StackOverflowt to a particular location

2. Set it to a certain width and height

3. Remove the caption/titlebar so the user can't move it around or close it

4. Remove that abilty to resize it (or any other user adjustments for that matter).

I've tried all the typical API functions (MoveWindow, SetWindowPos, SetWindowLong, etc...) but it refuses to do anything. Code currently works with all other processes and apps (such as internet explorer and the command prompt); it's almost as if the api calls don't apply to the osk, or that it's 'locked'. What am i missing? Thanks in advance.

I checked with Spy++ and the On-Screen Keyboard uses something called "DirectUIHWND". You may wish to look into DirectUIHWND APIs.

In addition, some people have warned that DirectUI is undocumented.
