The keys which are usually used to switch the language (like Right Ctrl for example) are not good to trap in Form.KeyPress(). Most of the keyboard switchers have their icon on System tray ( like native Windows 95 switcher). You can use that indicator to show the current language if you adjusted the form size the way you have Windows Taskbar up and visible.
At least that's what I do.
