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.

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.

structure of type WNDCLASS and calling the Windows RegisterClass()

|
class, we only need to do this when the first instance is initialized.

|
current instance address of the About() function. Then call Dialog
|
|
box which will create the box according to the information in your
|
|
generic.rc file and turn control over to the About() function. When
|
|
it returns, free the intance address.
