Answer 2

Use the textchanged event for the text box, use and if-then statement to see if the character you are interested in is there, like this: "if string.mid("H",mytextbox.text) > 0 Then myhelpscreen.show()" (this for if H was typed in the textbox)

and show your help screen there...

Instead of the textchanged event, you could also use something like the keypressed event...

Hope it helps...
