A Note About C/C++

It goes without saying that WMI can be accessed from C and C++. In fact, some WMI facilities cannot reasonably be accessed except through these languages. Unfortunately, however, a translation of these script examples into C++ and the accompanying explanation would quintuple the size of this appendix. If you are a C/C++ programmer, however, we offer you these few notes. First, WMI is a COM-based technology, so it is accessed using standard COM techniques. Each of the SWbem scripting components mentioned in this book has a standard COM equivalent. Their names are for the most part obvious, such as IWbemServices, IWbemObjectSink, IWbemObjectSet, and so on. Slightly counterintuitively if you are used to the scripting interface, ...
