std::vector hints that you may be reallocating, boost::scoped_array hints that you probably are not.

This is the big thing I was trying to get at. scoped_array is a static array, while vector is a dynamic one. In terms of performance, I don't see there being a difference. *edit: Except in the realm of custom allocators, which I know nothing about.

scoped_array does not resize the array, ever.

What I meant was this:
scoped_array pFeatureButtons; //"array size=0" (points to 0)
pFeatureButtons.reset( new HWND[count] ); //array size=count

std::vector would do basically the same allocations here, but the new call is just hidden inside the resize call.

Quote:It serves an entirely different job than vector.

It seemed that in this case pFeatureButtons was simply mimicing a dynamic array. The question now was only if std::vector was supposed to have this performance penalty over scoped_array or not.
