Remarks
When hok is registered as asynchronous the HookProc(Int32, IntPtr, IntPtr) function is called in special thread. You can use this approach to handle the event in your form and use Invoke(Delegate) to run event-handling code. The code then does not block keyboard hook which immediately returns.
