I can't get the following code to display a custom icon in a forms toolbox, 
it shows only the default sprocket icon.

Imports System.ComponentModel
Imports System.Data.SqlClient
Imports System.Drawing

<System.Drawing.ToolboxBitmap("c:\stop.bmp")> _
Public Class DataTextBox
        Inherits Panel

I do have the proper 16x16 image at the C:\ location. Any ideas?
