In this article, Raymond Chen explores the process of cloning a Windows Runtime vector in C++/CX, building upon the previous solution implemented in C++/WinRT. The initial translation to C++/CX is straightforward, with minor adjustments to accommodate the differences between the two frameworks. One notable difference is that C++/CX allows for custom equality comparers, unlike C++/WinRT which uses the default comparer. To capture the full generality of the Vector, the author introduces the ability for the caller of Clone­Vector to specify an equality comparer. Additionally, the article highlights the implementation of C++/CX collection types and provides insights into custom allocators.
