Hello all
I will have to develop a userform and I want to control the value of
TextBox which must be an integer not null. What do I have to do? I
wrote this but it is not the good code!!

Private Sub TextBoxl_Change()

Dim KeyAscii As MSForms.ReturnInteger

Select Case KeyAscii
Case Is < 49, Is 57
MsgBox "Only a non null interger is allowed."
KeyAscii = Asc(Chr(8))
End Select

End Sub
