On-Screen Keyboard has a manifest which is used for visual styles. However, the common controls aren't initialized and as a general rule the controls have to be loaded in the application's handle instance.
On-Screen Keyboard provides a mechanism to launch the application only once, to avoid multiple entry point instances. Such mechanism is based upon mutex objects, although it could happen that the program may end up creating two or more mutexes (a race condition).

Implement the coordination dialog data saver. This allows OSK to launch using the previous placement values. Such behaviour can be seen with the XP's part of On-Screen Keyboard.
- Implement the save/load handler for this feature
- Check the "Use Click Sound" item state accordingly depending if it's enabled or disabled
- Use PlaySoundW() to play the wave sound file from resource
- Add the WAV sound click file. The work is made thanks to Midori Mizuno
- Add the respective standard keyboard resource.
- Implement the standard/enhanced keyboard dialog switcher.
- Implement save/load handler.
- Move the warning box conditinal check (bShowWarning) to wWinMain application entry point (this will prevent the modal welcome box from displaying each time the user switches into another dialog).
CORE-14428
In Windows XP, both in On-Screen Keyboard and in Magnify there is a welcome box which is shown upon startup of the application. This feature is already implemented for Magnify in ReactOS which however in On-Screen Keyboard is still unimplemented.
