Hi. How can I trap keys like letters, numbers, and symbols using the Hardware library? E.G. If I press the letter a how can the lib catch this and fire the HardKeyPressed event? Thanks.

You should first change the form's KeyPreview property using the Door library (first example here):

Afterwards use the form's KeyPress event to catch all keys.

Hi Erel, Thanks for your quick reply. Is there a way to do this if the program's form doesn't have the focus, like the Hardware library let's you do with the HardKeys and arrows? Thanks.

Not that I can think of.
