Re: CArray vs CMap

CMap and CArray are both valid tools, but for different tasks.
If the key is an integer represented by item position, then there is no

But if you want to access the items stored in a container using a different
kind of key, for example a string, then CMap is the tool to choose.
(Note that there are also STL containers, like std::vector, std::map, etc.
which seems to be more carefully designed than MFC containers, at the cost
of maybe a bit more hard learning curve. However, STL containers with their
"ecosystem" of iterators and algorithms are a very versatile and powerful
tool, if you can invest some time and intellectual energy to learn them.)
Even with an integer key, a map can be preferable if the desired key values are
As you know, I agree with you about using the STL containers rather than the MFC
But CMap can potentially be more efficient than std::map for large containers
because it is a hash-map. (Modern versions of the C++ standard library have
hash_map, but I have never used it).
