[AccessD] Only allow 3 digits in a textbox

You can use the Change event and something like:

If me!txtMine.Text > 999 Then
   msgbox "Error Message Here - Invalid Entry"
   '....whatever you want to do with that entry goes here
end if

You'd have to check for IsNumeric and IsNull and handle those as well I'd
imagine, but this should get you started at least.

Hey Chris,

	The more that I look at the simple version, using the input mask,
the more I realize that it is its shortcomings. For example, if the user
clicks on the textbox in order to set focus, the insertion of the cursor is
where ever the user clicked and not at the beginning of the textbox.

Bob,

Remember the programmer's credo - the more complicated a solution, the more
fun it is to code!  ;)

Joe, Bob's idea is a good one.  But if you want to get the user more
involved in the proces, you could add code in the OnExit or AfterUpdate that
uses Len() to evaluate the length of the string and pops up a message box
prompting the user to enter appropriate data if more than 3 characters are
found.  If you want to be really strict, you can use SetFocus to keep the
user from tabbing out of that control until the 3-digit condition is
satisfied.

Joe

Maybe this is an overly-simplistic approach, but why don't you just specify
an Input Mask (000;;_) or (990;;_) ?
