Solution 1

If you want the contents of b followed by the contents of a then:

C++

b.Append(a);
a.Copy(b);

will do it.

HAve also a look at the InsertAt method: CArray Class | Microsoft Docs[^].

By the way, C++ standard library containers (e.g. std::vector) are usually better than corresponding MFC ones.

Definitely! I still use MFC and never, ever use its containers.
