So I'm playing with geotools and I thought I'd proxy one of their data-access classes and trace how it was being used in their code. I coded up a dynamic proxy and wrapped a FeatureSource (interface) in it and off it went happily. Then I wanted to look at some of the transitive objects returned by the featureSource as well, since the ma...

A friend of mine is working on a legacy VB6 project. I haven't touched that language in ten years, so I'm pretty rusty. Anyway, is there any kind of reflection API for VB6? Specifically, he needs a way to iterate the properties (and types) of a user-created Class. (In other words, not an external COM object, but an internal "Class Module...

We then use GetTypes() and further examine the types with each plugin file for supported Interfaces. A path for the plugins is provided by the user and we cycle through each of the files in the folder to see if it (the plugin) support...
Let us say we have a method which accepts two arguments o1 and o2 of type Object and returns a boolean value. I want this method to return true only when the arguments are instances of the same class, e.g.: foo(new Integer(4),new Integer(5)); Should return true, however: foo(new SomeClass(), new SubtypeSomeClass()); should return f...
