by: active | last post by:

Because of an example I followed I've been instantiating Image objects. Now I notice that the documentation says the Image class is an abstract base class. Things seem to be working! Is the documentation wrong (it also says abstract classes cannot be instantiated)? Should I be using Bitmap instead? Is there a difference between Abstract class and Abstract base class?

Hello! Whilst refactoring an application, I was looking at optimizing a ModelFactory with generics. Unfortunately, the business objects created by the ModelFactory doesn't provide public constructors (because we do not allow developers to instantiate them directly). Because our business objects are instantiated very frequently, the idea of using reflection sounds like a performance killer (I haven't done any tests on this, but the...

Searching My XML File Using Keyword Searches?

by: pbd22 | last post by:

Hi. I am somewhat new to this and would like some advice. I want to search my xml file using "keyword" search and return results based on "proximity matching" - in other words, since the search string will often not produce a direct match, the results will be based on proximity (50%, 20% 100%, etc). are there any good examples out there on how to do keyword searches on XML data?
