Events with static functions
I have a class that is able to detect a global key press. However, I don't seem to be able to create a working event that notifies the Form1 of a global keypress.
The function "HookCallba ck" is static and for some reason it does work to the point of " MyAKeyWasPresse d(int vkKeyCode)" displaying it's 2 messageboxes but the function in Form1 doesn't get fired and displays no messagebox.
What do I do... -
