Hello! I have a class hierarchy that consists mainly of one base class CtxBase, and two children: LoginCtx and DisconnectCtx. Now, there's a need to provide an interfaces for this hierarchy. I'd like to export this classes from a DLL. And I'm in doubt how can I achieve this? My first option was to define a base interface (ICtxBase) and then... more »

	I would like to change my job

how much time?

I am aware that this is, technically, not a question about c++ but surely here someone will now-how-to. I have a program, with lots of routines, and complicated stuff. I want to optimize it but I don't want to optimize all the parts, but rather the ones in which it takes longer. Of course one can put time logs in the program, but there must... more »

	Why can't member function be friend?
	I want to show you an example how two classes can have relationship instead of an inheritance. The inheritance is not an option if you want to define two classes. The relationship between two classes can be friends when variables can be modified in both classes. As far as we discussed in an earlier... more » By immortal_ne...@hotmail.com - Sep 4 - 2 new of 2 messages

type punning

I am curious about creating some macro's for keeping track of where memory has been allocated on the heap. For example it would be nice to be able to detect memory leaks at the end of program execution. I would like a system that does not incur to much size and speed overhead. Here is my design for a way to manage who created what and... more »
