/*
*  Package Operations:
*  -------------------
*  This package demonstrates how to build a C++\CLI WPF application.  It 
*  provides one class, WPFCppCliDemo, derived from System::Windows::Window
*  that is compiled with the /clr option to run in the Common Language
*  Runtime, and another class MockChannel written in native C++ and compiled
*  as a DLL with no Common Language Runtime support.
*
*  The window class hosts, in its window, a tab control with three views, two
*  of which are provided with functionality that you may need for Project #4.
*  It loads the DLL holding MockChannel.  MockChannel hosts a send queue, a
*  receive queue, and a C++11 thread that reads from the send queue and writes
*  the deQ'd message to the receive queue.
*
*  The Client can post a message to the MockChannel's send queue.  It hosts
*  a receive thread that reads the receive queue and dispatches any message
*  read to a ListBox in the Client's FileList tab.  So this Demo simulates
*  operations you will need to execute for Project #4.
*
*  Required Files:
*  ---------------
*  Window.h, Window.cpp, MochChannel.h, MochChannel.cpp,
*  Cpp11-BlockingQueue.h, Cpp11-BlockingQueue.cpp
*
*  Build Command:
*  --------------
*  devenv CppCli-WPF-App.sln
*  - this builds C++\CLI client application and native mock channel DLL
*
*  Maintenance History:
*  --------------------
*  ver 3.0 : 22 Apr 2016
*  - added support for multi selection of Listbox items.  Implemented by
*    Saurabh Patel.  Thanks Saurabh.
*  ver 2.0 : 15 Apr 2015
*  - completed message passing demo with moch channel
*  - added FileBrowserDialog to show files in a selected directory
*  ver 1.0 : 13 Apr 2015
*  - incomplete demo with GUI but not connected to mock channel
