MSDN Magazine Article: Simplify Safe Array Programming in C++

The March 2017 issue of MSDN Magazine contains a feature article of mine on simplifying safe array programming in C++ with the help of the ATL’s CComSafeArray class template.

There is also an accompanying web-only side bar introducing the SAFEARRAY C data structure and some of the basic operations available for it via Win32 API calls, although for C++ code I encourage the use of a convenient higher-level C++ object-oriented wrapper like ATL::CComSafeArray.

Safe arrays are useful for example when you have a COM component and you want to exchange array data between the component and its clients (that can be potentially written in languages even different than C++, e.g. C#, or scripting languages).

I wish I could have had such a resource available when I did some safe array programming in C++.

Some of the insights and experience I developed in that regard are distilled in the aforementioned article.

I hope it may be helpful to someone.
