WINDOWS PROGRAMMING SDK-STYLE NULL, // Menu handle hInstance, // Application's instance handle NULL // Window-creation data ); ShowWindow (hwnd, nCmdShow); UpdateWindow (hwnd); while (GetMessage (&msg, NULL, 0, 0)) { TranslateMessage (&msg); DispatchMessage (&msg); } return msg.wParam; } LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { PAINTSTRUCT ps; HDC hdc; switch (message) { case WM_PAINT: hdc = BeginPaint (hwnd, &ps); Ellipse (hdc, 0, 0, 200, 100); EndPaint (hwnd, &ps); return 0; case WM_DESTROY: PostQuitMessage (0); return 0; } return DefWindowProc (hwnd, message, wParam, lParam); } #include <windows.h> LONG WINAPI WndProc (HWND, UINT, WPARAM, LPARAM); int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow) { WNDCLASS wc; HWND hwnd; MSG msg; wc.style = 0; // Class style wc.lpfnWndProc = (WNDPROC) WndProc;// Window procedure address wc.cbClsExtra = 0; // Class extra bytes wc.cbWndExtra = 0; // Window extra bytes wc.hInstance = hInstance; // Instance handle wc.hIcon = LoadIcon (NULL, IDI_WINLOGO); // Icon handle wc.hCursor = LoadCursor (NULL, IDC_ARROW); // Cursor handle wc.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1); // Background color wc.lpszMenuName = NULL; // Menu name wc.lpszClassName = "MyWndClass"; // WNDCLASS name RegisterClass (&wc); hwnd = CreateWindow ( "MyWndClass", // WNDCLASS name "SDK Application", // Window title WS_OVERLAPPEDWINDOW, // Window style CW_USEDEFAULT, // Horizontal position CW_USEDEFAULT, // Vertical position CW_USEDEFAULT, // Initial width CW_USEDEFAULT, // Initial height HWND_DESKTOP, // Handle of parent window

3. MFC Design Philosophy • Provide an object-oriented interface to the Windows operating system that supports reusability, self-containment, and other tenets of OOP.MFC Design Philosophy • Avoid undue overhead on the system or unnecessarily adding to an application's memory requirements • Document/View Architecture • MFC Class Hierarchy (CObject) • Serialization Support • Run-time class information support • Diagnostics & debugging support

6. Demo!!! • Multishape Example to demonstrate Serialization • Windows Template Example • Addition of simple transformation to Template • Unix Demo

7. Sample for Windows Programming • 1. Rebuild the solution on the first time. • 2. Check the classes at the Class View window. • 3. Check the function CKingimageView::OnProcess() • 4. Check the Menu IDO_KINGIMTYPE at the Resource View window. • 5. New image can be saved.

8. TIPS • Delete “Debug” folder before submitting. • Download .NET https://msdn04.e-academy.com/binghamton_watson/ • No images either if they are too big. • Submit using dropbox. (Demo) • Readme (Template will be provided).
