Started learning .Net, having heaps of fun with Visual Web Developer Express and SQL Express.
Been working through some online tutorials for Visual Web Developer Express, currently doing this one:
In steps 6 and 7 I have encountered something I do not understand. I'm sure it is simple, but I need help to understand it.
6. In the Solution Explorer, right-click app_code and select Add New Item. Add a new Class file named "PageBase" (followed by the extension of the language you are using, whether .cs, .vb or .js).
Wrap the class declaration in a "GeekSpeak" namespace declaration. <== what does this mean?????
7. Derive the class from Page and then add the following code to the class (in C#, make sure your public class looks like: "public class PageBase : System.Web.UI.Page" and that you add "namespace GeekSpeak" just above the Public class declaration): <== what does it mean "Derive the class from the page" ????
