Includes and their size

I have tried to get myself into the habit of making sure I HAVE to include a thing like windows.h before I do...and if I do I almost always put the WIN32_LEAN_AND_MEAN macro.

Well, I have a WaveClass which is used to load up waves and such with play functions...but mainly I just need to loaded wave to pass into DirectSound Buffers.

The wave class needs GlobalAlloc, and GlobalLock, BYTE, DWORD...etc
I have to include MMSystem.h, and Windows.h. Will this lengthen the size in memory of the wave class?
There is a good chance I could have 100+ of these class's loaded at any time. If those extra includes are goona cause some runtime slowdowns or extra size during runtime then i need to find a way around it.

Not 100% sure...but pretty.....it will only include it one time...not every time for every new object. So no, it won't make that much diffrence.

Properly written header files, especially system includes, never increase final code size, only compile time. The only exception are inlines, which ought to be thrown out if not used.

What about Templates...they would do that too, wont they?

Templates only exist in the final code if you actually use them.
