如何在VB.NET/Visual Studio 2008中允许空格键和退格键？

示例代码:

Private Sub txtname_KeyPress(ByVal sender As System.Object, _
                             ByVal e As System.Windows.Forms.KeyPressEventArgs) _
                             Handles txtname.KeyPress

    If e.KeyChar < "A" Or e.KeyChar > "z" And e.KeyChar <> ControlChars.Back Then
        e.Handled = True
        txtname.Clear()
    Else
    End If
End Sub
