preventing copy and paste in a text box

[stemitch2000]

Hello people,

Please can you help me? I have a text box, but do not wish the user to be able to paste into the text box. They are allowed to write in it - but not paste into it. Anyone know how I go about doing this? I suppose I could see if the first key pressed is a ctrl, but is there a simplier way.

Thank you

nope, even trapping ctrl key wont do as the user can always right click and paste...

I believe the only way to prevent the user from pasting into a text box would be to make the box readonly. This would, however, also prevent the user from typing anything into the box, as well.

uhm, check with the javascript forum, as i remember there's abilities in javascript to copy/paste from within script and in turn i would assume it's possible to trap these events in reverse to prevent them
