Preventing copy/paste in text boxes

[DaveMere]

Hi all,

I'd like to prevent the input of inappropriate characters to a text box. I have an ascii check on the KeyPress event which weeds out non-numeric and non-alphabetic characters, however it is still possible to add dodgy characters via the paste option on the right-click dropdown menu. Is there a property I can set to prevent pasting into a text box? Or will I have to check the contents of the text box through code?

Cheers,

DaveMere

Try using the onchange event instead,

As redsmooth stated, use the Change Event in code. This would be easiest.

There is the possibility to use the EditBox's undo feature (API) (or your own) when the pasted text is incorrect.

Otherwise, you would need to catch the pasting in the KeyDown AND KeyPress AND the PopUp menu.

Excellent, that seems to work.

Thanks
