Validating length of textbox

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

Each time it changes (Change event, I suppose) you check the new value.

As it turns out, validating controls depends on what type of control and the format of the data you wish to validate.Damnit, I've got to stop spending so much time here - I keep getting carried away. Might be more trouble than it's worth though - nothing on the form is currently bound to anything. It's not bound to anything, just used in code, but I'd prefer to limit it in the control rather than validating afterward. Using the Key Press event is a slightly different idea (in as much as using the Change event has already been discussed - which is fundamentally very similar), but your usage of it is not quite correct.I'm just using the form to get input a la VB6, then building and executing a query, and closing the form. Does a textbox on an Access form have an equivalent of the VB6 . There is a little known and undocumented method for limiting the number of Input characters in an Access Text Box using the API, here it goes: Private Declare Function Send Message Long Lib "user32" Alias _ "Send Message A" (By Val h Wnd As Long, By Val w Msg As Long, _ By Val w Param As Long, lng Value As Long) As Long Private Declare Function Get Focus Lib "user32" () As Long Private Const EM_SETLIMITTEXT As Long = &HC5 There is a little known and undocumented method for limiting the number of Input characters in an Access Text Box using the API, here it goes: Private Declare Function Send Message Long Lib "user32" Alias _ "Send Message A" (By Val h Wnd As Long, By Val w Msg As Long, _ By Val w Param As Long, lng Value As Long) As Long Private Declare Function Get Focus Lib "user32" () As Long Private Const EM_SETLIMITTEXT As Long = &HC5 Ditto. To avoid handling the new character you should set Key Ascii to 0.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.

Consider, for example, what would happen if the field is full and I select a few characters then type a letter to replace them.
