46f059bea92bedbd395793702c73946ead235586vboxsync * tstVBoxAPIWin - sample program to illustrate the VirtualBox
46f059bea92bedbd395793702c73946ead235586vboxsync *                 COM API for machine management on Windows.
46f059bea92bedbd395793702c73946ead235586vboxsync                   It only uses standard C/C++ and COM semantics,
46f059bea92bedbd395793702c73946ead235586vboxsync *                 no additional VBox classes/macros/helpers. To
46f059bea92bedbd395793702c73946ead235586vboxsync *                 make things even easier to follow, only the
46f059bea92bedbd395793702c73946ead235586vboxsync *                 standard Win32 API has been used. Typically,
46f059bea92bedbd395793702c73946ead235586vboxsync *                 C++ developers would make use of Microsoft's
46f059bea92bedbd395793702c73946ead235586vboxsync *                 ATL to ease development.

46f059bea92bedbd395793702c73946ead235586vboxsync * PURPOSE OF THIS SAMPLE PROGRAM
46f059bea92bedbd395793702c73946ead235586vboxsync * ------------------------------
46f059bea92bedbd395793702c73946ead235586vboxsync *
46f059bea92bedbd395793702c73946ead235586vboxsync * This sample program is intended to demonstrate the minimal code necessary
46f059bea92bedbd395793702c73946ead235586vboxsync * to use VirtualBox COM API for learning puroses only. The program uses pure
46f059bea92bedbd395793702c73946ead235586vboxsync * Win32 API and doesn't have any extra dependencies to let you better
46f059bea92bedbd395793702c73946ead235586vboxsync * understand what is going on when a client talks to the VirtualBox core
46f059bea92bedbd395793702c73946ead235586vboxsync * using the COM framework.
46f059bea92bedbd395793702c73946ead235586vboxsync *
46f059bea92bedbd395793702c73946ead235586vboxsync * However, if you want to write a real application, it is highly recommended
46f059bea92bedbd395793702c73946ead235586vboxsync * to use our MS COM XPCOM Glue library and helper C++ classes. This way, you
46f059bea92bedbd395793702c73946ead235586vboxsync * will get at least the following benefits:
46f059bea92bedbd395793702c73946ead235586vboxsync *
46f059bea92bedbd395793702c73946ead235586vboxsync * a) better portability: both the MS COM (used on Windows) and XPCOM (used
46f059bea92bedbd395793702c73946ead235586vboxsync *    everywhere else) VirtualBox client application from the same source code
46f059bea92bedbd395793702c73946ead235586vboxsync *    (including common smart C++ templates for automatic interface pointer
46f059bea92bedbd395793702c73946ead235586vboxsync *    reference counter and string data management);
ad27e1d5e48ca41245120c331cc88b50464813cevboxsync * b) simpler XPCOM initialization and shutdown (only a single method call
46f059bea92bedbd395793702c73946ead235586vboxsync *    that does everything right).
46f059bea92bedbd395793702c73946ead235586vboxsync *
46f059bea92bedbd395793702c73946ead235586vboxsync * Currently, there is no separate sample program that uses the VirtualBox MS
46f059bea92bedbd395793702c73946ead235586vboxsync * COM XPCOM Glue library. Please refer to the sources of stock VirtualBox
46f059bea92bedbd395793702c73946ead235586vboxsync * applications such as the VirtualBox GUI frontend or the VBoxManage command
46f059bea92bedbd395793702c73946ead235586vboxsync * line frontend.
