Unfortunately, that method will not prevent users from pasting in "invalid"
characters. Here is some code that I first posted to the compiled VB
newsgroups, but have modified for Excel's VBA world... it will restrict the
characters allowed in the TextBox (whether typed or pasted) to only the
digits 0 thru 6 (the allowable characters are controlled by the list in the
2nd If..Then statement); also note that I have the routine Beep for invalid
characters, although the display of a text message is doable if desired...

'************* START OF CODE *************
Dim LastPosition As Long

Private Sub TextBox1_Change()
Static LastText As String
Static SecondTime As Boolean
If Not SecondTime Then
With TextBox1
If .Text Like "*[!0-6]*" Then
Beep
SecondTime = True
.Text = LastText
.SelStart = LastPosition
Else
LastText = .Text
End If
End With
End If
SecondTime = False
End Sub

Private Sub TextBox1_MouseDown(ByVal Button As Integer, _
ByVal Shift As Integer, _
ByVal X As Single, ByVal Y As Single)
With TextBox1
LastPosition = .SelStart
'Place any other MouseDown event code here
End With
End Sub

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
With TextBox1
LastPosition = .SelStart
'Place any other KeyPress checking code here
End With
End Sub
'************* END OF CODE *************

I missed the "digits" part of your question. My previous reply
restricts TextBox1 to 2 characters, not necessarily 2 digits. Use the
following instead. It limits input to 2 digits.

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
If Len(Me.TextBox1.Text) = 2 Then
KeyAscii = 0
Else
Select Case KeyAscii
Case vbKey0 To vbKey9
' OK
Case Else
KeyAscii = 0
End Select
End If
End Sub

How do I limit TextBox data entry to 2 digits?
