Dispose method implementation problem!!!

[pound]

Here is code from MSDN-Library April 2003 which I tried to implement to my class but there was some error that I don't know how to solve it. In Privete Overloads Sub Dispose(ByVal disposing Boolean), the code call component.Dispose() method but the VS said that 'System.ComponentModel.Component.Protected Overrridable Sub Dispose(disposing As Boolean)' is not accessible in this context because it is 'Protected'. I don't know this code is from .NET Framework 1.0 and not yet update for 1.1 or not. If anyone know how can I correct this error, please let me know.

Thank you,
