Unresolved external symbol on static class members

Very simply put: I have a class that consists mostly out of static public members, so I can group similar functions together that still have to be called from other classes/functions.

Is it better to store class constants in data members or in methods?

I recently wrote a class that renders B-spline curves. These curves are defined by a number of control points. Originally, I had intended to use eight control points, so I added a constant to the class, like so: class Curve { public: static const int CONTROL_POINT_COUNT = 8; }; Now I want to extend this class to allow an arbi...

Should lookup tables be static

I have a Message class which parses text messages using lookup tables. I receive a lot of messages and create and destroy a lot of objects so I thought I declare those lookup tables as static members to prevent initializing the same tables with the same values again and again.

Access identically named class members of instances of different classes

I have instances of class A and B, and both classes implement a member 'Text'. Is there a way to access member Text in a generic way?

Why would you see...
