Maximum Character Length

[toxicpaint]

Hi,

I'm sure there is a really easy way to do this and I'm just being silly, but is there a way that I can get a text box to stop people typing when it hits its maximum character length.

I've created an page with a notes section you see and this writes to an Access database. the problem is that Access can only take 255 characters as a maximum. I have set a MaxChar value in the properties of the text box but you can type in as much stuff as you like.

Can anyone help?

Thanks a lot,

Tom

Thanks a lot for that. I had to change ..Text.len into Text.Length as visual basic didn't recognise it but the strtucte seems to be okay.

I can't seem to supress keys though. Do you know how I can suppress all keys except backspace and tab?

Thanks!
