    SOLVED: Limiting textbox to number issue


    Hello.

    I have the following code on Keypress of a textbox. to limit the repsonse to just numbers. Which works great!
    However I need it to only allow four digits and be able to use the backspace key to delete.
    But it allows any length of number and also wont allow the backspace key to delete.
    Any help please! Thanks.

    Code:
    Private Sub txtEntranceDoorsFlatsRenewYear_KeyPress(KeyAscii As Integer)
    Const Number$ = "0123456789" ' only allow these characters
    If KeyAscii <> 4 Then
       If InStr(Number$, Chr(KeyAscii)) = 0 Then
          KeyAscii = 0
          Exit Sub
       End If
    End If
    End Sub

    RESOLVED!
    Changed to bound table field length then used the following code:
    Code:
    Private Sub txtEntranceDoorsFlatsRenewYear_KeyPress(KeyAscii As Integer)
        'If a backspace (ASCII-8) or a tab (ASCII-9) was
        ' entered, allow it unconditionally.
        If (KeyAscii = 8) Or (KeyAscii = 9) Then Exit Sub
        If IsNumeric(Chr(KeyAscii)) <> True Then KeyAscii = 0
    End Sub

    I have set the length in the field from the bound table and then used an IF after update to restrict an invalid year i.e < than current year.
    That has worked for me.
