----------------------------------------------------------- From: SitaramanM Message 2 in Discussion Hi Ambrose In a nutshell "Overriding allows a subclass to alter or replace an existing method with the permission of the base class designer. Shadowing can be done without the permission of the base class designer, which is a risky proposition and one that requires extensive testing because the base class was never designed with such a thing in mind. Also, as we discussed earlier, overriding uses virtual methods so the implementation of the method that is invoked is based on the data type of the underlying object, not the data type of the variable we're using. When a method is shadowed it is not virtual, and it is the data type of the variable that dictates the implementation of the method that will be used. The data type of the underlying object is ignored" Check out the article "Overriding My Shadows" at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnadvnet/html/vbnet12252001.asp. Gives you a clear understanding btwn overriding and shadows(new in C#). It also has some gr8 samples to demonstrate the differences hth regards, sr ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/BDotNet/_emailsettings.msnw Need help?
