Keyboard Map, Updating Present Language?

I am using the following code to bring up the keyboard map in an application:

System.Diagnostics.Process.GetProcessesByName("Filename.exe")
System.Diagnostics.Process.Start("osk")

It works great, but I also have three radio buttons that change the language at the application level only, and when I click one, the language on the keyboard map should update, but does not. The only time it updates is when the mouse is over the keyboard map. Is there a way to detect if the keyboard map is shown, so I can make it update to the new language?

You cannot just make a variable like:keyboardMapPresent = True - because you have to also be able to detect when the keyboard map is closed!
