Another alternative would be to keep track of the current value in the field.

I've just spent a few minutes browsing the References list and don't really like what I saw. I've just spent a few minutes browsing the References list and don't really like what I saw.Did you even try testing this before arguing the point.Especially as the problem has already been pointed out to you.However, you do make a good point that the code I posted would not handle deleting characters when the maximum length had been reached. :-) Seems to me, the simplest thing would be to just chop off the last character, something like the proposal in message #22.The solution is certainly not to play around with adding a backspace character, but could be handled by allowing the Del or Backspace characters through regardless of the limit. I really don't like the idea of playing around with keypress, as it interferes too much with normal operation of the field.We also added the typical actions to the window menu for managing tabs.

Note: Native tabs on mac OS High Sierra (10.13) are currently only partially supported. We've updated the VS Code logo and colors, orange for the stable release and green for Insiders.

Does a textbox on an Access form have an equivalent of the VB6 . Although it doesn't account for the possibility of a black (zero) background, here's the routine I used.

It's not bound to anything, just used in code, but I'd prefer to limit it in the control rather than validating afterward. Does a textbox on an Access form have an equivalent of the VB6 . I just turn the field background red as long as the value is not within the required length.

Yeah, I thought about chopping it off, but decided against it.

The users know the limits, if they choose to ignore the warning then so be it.

In fact I vaguely recall seeing this years ago when discussing VB, but of course with the Max Length property it wasn't needed. Setting it to 8 (or BS) would ensure you lost the last (24th in this case) character and be left with a 23 char string. The character isn't added until the Key Press event procedure has been completed as it is used to determine which charater, if any, should be added.
