PROGRAM: Generic.c
PURPOSE: Generic template for Windows applications
FUNCTIONS:
WinMain() - calls initialization function, processes message loop InitApplication() - initializes window data and registers window InitInstance() - saves instance handle and creates main window WndProc() - processes messages CenterWindow() - used to center the "About" box over application window About() - processes messages for "About" dialog box
COMMENTS:
The Windows SDK Generic Application Example is a sample application that you can use to get an idea of how to perform some of the simple functionality that all Applications written for Microsoft Windows should implement. You can use this application as either a starting point from which to build your own applications, or for quickly testing out functionality of an interesting Windows API.
This application is source compatible for with Windows 3.1 and Windows NT.

FUNCTION: WinMain(HINSTANCE, HINSTANCE, LPTSTR, int)
PURPOSE: calls initialization function, processes message loop
COMMENTS:
Windows recognizes this function by name as the initial entry point for the program. This function calls the application initialization routine, if no other instance of the program is running, and always calls the instance initialization routine. It then executes a message retrieval and dispatch loop that is the top-level control structure for the remainder of execution. The loop is terminated when a WM_QUIT message is received, at which time this function exits the application instance by returning the value passed by PostQuitMessage().
If this function must abort before entering the message loop, it returns the conventional value NULL.

FUNCTION: InitApplication(HINSTANCE)
PURPOSE: Initializes window data and registers window class
COMMENTS:
This function is called at initialization time only if no other instances of the application are running. This function performs initialization tasks that can be done once for any number of running instances.
In this case, we initialize a window class by filling out a data structure of type WNDCLASS and calling the Windows RegisterClass() function. Since all instances of this application use the same window class, we only need to do this when the first instance is initialized.
