Question

I have an application that displays a keyboard and tests whether the keys have been pressed or not. The issue I’m having is that when certain keys are pressed like the arrow buttons/tab, the keyboard graphic loses focus and it starts accessing menu items/etc. I tried registering to the preview mouse down event in the MainWindow and setting e.handled = true. But this does not work all the time. It would also be nice if there was a way to disable the windows button as well.

I used this class:

I replaced line 99 with this code:

return EnableKeyboard ? InterceptKeys.CallNextHookEx(hookId, nCode, wParam, lParam) : (IntPtr) 1;

Where EnableKeyboard is set by the user.
