The best solution is to allow any input and check it in the textbox's
Validating event.

This will prevent the user from typing an "A":

\\\
Private Sub TextBox1_KeyPress( _
ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyPressEventArgs _
) Handles TextBox1.KeyPress
If e.KeyChar = "A" Then
e.Handled = True
End If
End Sub
///
