This function enables or disables the keyboard.
The EnableHardwareKeyboard function is useful for applications in which a user can write on the touch screen. When the keyboard is disabled, a user can rest a hand on it without causing spurious keyboard input. Use the disable mode carefully. If an application hangs while the keyboard is disabled, the keyboard is not available to other applications.
When EnableHardwareKeyboard changes the enabled state of the keyboard, it causes menus, tabs, buttons and static controls to repaint themselves, so they can change the way they display keyboard accelerators or other relevant information.
