Simple Key Replacer

saw some cool open source for a key replacer but recently learned that the functions inside an OCX cant be viewed or edited so i am wanting to make my own (preferably w/o an OCX)
here is how it is:

let say the user entered in any input from the keyboard this program replaced it with a custom message for example the user would type "hi how are you" and on any input where they were typing this "the keyboard has been disabled for security purposes" would come up. Any ideas on how i can do this??
(sorry for the newbie questions i am way better w/ C++ but i need a VB app for certain reasons)

from what i have been reading around here something like this is a breeze for some of u guys. Sorry i posted something similar in the GD area w/o spotting this project help forum first.

Any advice, insight, or help would be greatly appreciated!!

you can use the sendinput api function to add the "the keyboard has been disabled for security purposes" message. As for detecting what is typed, there is an api function that returns the last key press but i cant remember what its called :mad:

When u find out what the function is, you can use it with a timer to monitor keyboard input. I would recomend having a browse of vbapi.com
