Office 2010 Professional Plus VC + + lecture notes

one, windows programming is really a kind of event-driven programming approaches, mainly based on the message. When end users have to have to total a perform,Office 2007, call the OS wants some assistance, and OS user wants to deal the message,Windows 7 Serial, and put into the message queue, the final software eliminated from your message queue the message and reply. 2, message construction: typedef struct tagMSG / / msg HWND hwnd; / / Receive the message window handle.

4, utilizing the VC in addition to an excellent C programming fundamentals required to grasp two: 1, the message itself. Symbolize the different user information and application state. Second, for a particular message is, let the OS performs a specific function to reply to messages.
5,Office 2010 Key, Window plan entry: int WINAPI WinMain ( HINSTANCE hInstance, / / manage the existing case. HINSTANCE hPrevInstance, / / previous case handle.

Usually 0. int cbWndExtra; / / window additional bytes. Usually set to 0. HANDLE hInstance; / / the current application instance handle. HICON hIcon; / / icon handle LoadIcon (); HCURSOR hCursor; / / Cursor handle LoadCursor (); HBRUSH hbrBackground; / / brush handle (HBRUSH) GetStockObject (); LPCTSTR lpszMenuName; ; / / menu name LPCTSTR lpszClassName; / / class name WNDCLASS;

8, window class registration: ATOM RegisterClass ( CONST WNDCLASS * lpWndClass / / address of structure with class ; / / data
