269//
270///////////////////////////////////////////////
271//
272// These comments explain the how to receive notifications from the threads that the
273// Port Forward Engine creates when running COM requests for device information or for
274// retreival/change of port mappings.
275//
276// There are five functions that create threads, and each function takes a HWND as a
277// parameter. During execution of the thread, each thread will post messages to this HWND,
278// so as to notify the HWMND of the thread's progress through the needed COM tasks. The
279// message is always the same: a UINT named UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION.
280// Encodings of the WPARAM and LPARAM within the message will enable the HWND to determine
281// what's going on inside the thread. The five functions are:
282//
283// GetMappingsUsingThread()
284// EditMappingUsingThread()
285// AddMappingUsingThread()
286// DeleteMappingUsingThread()
287// GetDeviceInformationUsingThread()
288//
289// The comments below explain each how to modify your class to receive the thread's notification
290// message, and also explain how to decode the WPARAM and LPARAM values
291
292
293
294// define the value of the registered Window message. An arbitrary GUID is included, to ensure uniqueness
295
296
297extern const UINT UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION = ::RegisterWindowMessage(
298 _T("UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION-{7C29C80A_5712_40e8_A124_A82E4B2795A7}") );

304// GetMappingsUsingThread()
305//
306//////////////////////////////////////////////
307//
308// The GetMappingsUsingThread() function populates a std::vector of PortMappingContainer's with port
309// mappings that it finds using a thread. The reason for the thread is that COM retrieval of
310// port mappings is SLOW. Moreover, retrieval of the port mappings also BLOCKS the message
311// pump, so without a separate thread the application would otherwise appear to be hung/frozen.
312//
313// The thread frees the user interface of your program to do other things. The price you
314// pay for this convenience is that communication to your application is via Windows messages,
315// which the thread sends to your application and which your application must interpret and process.
316//
317// To use this function, your program must be able to receive (and process)
318// a registered window message posted from the thread when the thread is finished.
319// Thus, you must pass in a HWND of one of your windows that will receive the message. Typically,
320// you would choose your CMainFrame window (use the ::AfxGetMainWnd() function). However, you might
321// choose a different window, such as your CView-derived window for SDI applications
322//
323// The window that you choose must be able to process the message, which is a UINT named
324// UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION. For an MFC application, here are the changes
325// you must make to your CWnd class:
326//
327// 1. Declare a handler in your .h file using the following signature, in which
328// the name "OnMappingThreadNotificationMeesage" is arbitrary (ie, you can use
329// any name that you want, but you must be consistent):
330//
331// afx_msg LRESULT OnMappingThreadNotificationMeesage(WPARAM wParam, LPARAM lParam);
332//
333// 2. In your *.cpp file include the following "extern" statement somewhere at the beginning of
334// the file. This statement tells the linker that the value of the message is defined elsewhere:
335//
336// extern const UINT UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION; // defined in PortForwadEngine.cpp
337//
338// 3. In your .cpp implementation file, add an entry to the message map as follows:
339//
340// ON_REGISTERED_MESSAGE( UWM_PORT_FORWARD_ENGINE_THREAD_NOTIFICATION, OnMappingThreadNotificationMeesage )
341//
342// 4. Again in your .cpp file, write the body of the OnMappingThreadNotificationMeesage() function.
343// Typically, you would check the WPARAM parameter to determine the nature of the notification.
344// WPARAM == CPortForwardEngine::EnumPortRetrieveInterval is sent at intervals, where
345// LPARAM goes from 0 to 10. You can use this to update a progress control (if you want)
346// WPARAM == CPortForwardEngine::EnumPortRetrieveDone is sent when the thread is done, where
347// LPARAM signifies if the thread was or was not successful (S_OK or E_FAIL). Call the
348// GetPortMappingVector() function to get a copy of the current contents of
349// std::vector< CPortForwardEngine::PortMappingContainer > m_MappingContainer
