Catching All Keys
Im having some difficulty attemting to catch ALL keys pressed by a user, not just the ones detected on the form with the Key Preview property. I have googled and it researched it with no such luck...Yes this is for a Key Logger! (my fiance is acting funny)

Hmm, give this a whirl and YES i no its horribly ugly and not elegent and poor practice code. Note this is for educational purposes ONLY

}Note: I would suugest that you work it out with her...and NOT use this code. I AM NOT RESPONSABLE FOR HOW YOU USE THIS CODE!!!!! YOU USE AT YOUR OWN RISK! AND I DONT CONDONE USING IT FOR ILLEGAL PURPOSES! THIS IS MEANT TO BE FOR EDUCATIONAL USE ONLY. |

 . Anyways, keylogger is the way to go, its a tough world and the biggest lesson i have learned is that everyone gets sick of you some time, no matter how great you are to them.. it just takes time.

I'd highly recommend against using a keylogger as well,
If you are upset with her about trust issues, she'd be just as upset if she suspected you were spying on her. On the other hand if you were direct and upfront about a hardware upgrade she might be slightly more understanding  -MBirchmeier |

LOL, i want to thank all of you for your input on the situation... I brought it to her attention that she was acting a little funny. She said "wow, i didn't even relize it until you explain it to me". I told her about my plans to infect her computer with a key logger... she told me she thinks it is a good idea! Shes wants to prove to me that no matter what happens she could never hurt me that bad. She claims that would be just crazy to put me through that much pain. So the new question is should I? even with her permission? Or do i completely trust her and let it go?
