Keypress

I have problem with this code;

If (e.KeyChar < Chr(48) Or e.KeyChar > Chr(57)) And (e.KeyChar <> Chr(8)) Then
e.Handle = True

End If

I need a code that trap non numeric key and allow backspace and period!

I always use this as needed .

VB Code:

Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        'Numeric keys start with 48 through 52
        'backspace key has the ascii code 8
        'period key has the ascii code 46
 
        Dim KeyAscii As Integer
        KeyAscii = Asc(e.KeyChar)
 
        'only disallow numeric values
        Select Case KeyAscii
            Case Asc("0") To Asc("9")
                'acceptable keystrokes 
                e.Handled = True
                '   Case Asc(".") if you want to disable
                                  'other keys
 
 
                    'e.Handled = True 
            Case Else
                e.Handled = False
        End Select
    End Sub

have fun!
