VC第2次实验项目

1、第2次实验题目：Windows应用程序框架设计一、实验目的：1.熟悉Windows编程基本知识。2.掌握Windows应用程序的基本框架设计。二、实验题目内容及要求：1.分别用WNDCLASSEX和WNDCLASS作为窗口的数据结构，创建 “Win32”的“Windows应用程序”，分析系统生成的程序模块结构关系。程序代码：#include #include #include #include static TCHAR szWindowClass = _T(win32app);static TCHAR szTitle = _T(我的Win32程序 );HINSTANCE hInst;LRESU

2、LT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)WNDCLASSEX wcex;wcex.cbSize = sizeof(WNDCLASSEX);wcex.style = CS_HREDRAW | CS_VREDRAW;wcex.lpfnWndProc = WndProc;wcex.cbClsExtra = 0;wcex.cbWndExtra = 0;wcex.hI

3、nstance = hInstance;wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_APPLICATION);wcex.hCursor = LoadCursor(NULL, IDC_ARROW);wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);wcex.lpszMenuName = NULL;wcex.lpszClassName = szWindowClass;wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_APP

4、LICATION);if (!RegisterClassEx(&wcex)MessageBox(NULL,_T(Call to RegisterClassEx failed!),_T(Win32 Guided Tour),NULL);return 1;hInst = hInstance; HWND hWnd = CreateWindow(szWindowClass,szTitle,WS_OVERLAPPEDWINDOW,CW_USEDEFAULT, CW_USEDEFAULT,500, 100,NULL,NULL,hInstance,NULL);if (!hWnd)MessageBox(NUL

5、L,_T(Call to CreateWindow failed!),_T(Win32 Guided Tour),NULL);return 1;ShowWindow(hWnd,nCmdShow);UpdateWindow(hWnd);MSG msg;while (GetMessage(&msg, NULL, 0, 0)TranslateMessage(&msg);DispatchMessage(&msg);return (int)msg.wParam;LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM

6、lParam)PAINTSTRUCT ps;HDC hdc;TCHAR greeting = _T(你好, 同学!);switch (message)case WM_PAINT:hdc = BeginPaint(hWnd, &ps);TextOut(hdc,5, 5,greeting, _tcslen(greeting);EndPaint(hWnd, &ps);break;case WM_DESTROY:PostQuitMessage(0);break;default:return DefWindowProc(hWnd, message, wParam, lParam);break;return 0;程序运行结果是：2. WNDCLASSEX和WNDCLASS这两种窗口数据结构的成员有什么区别，写出所对应的窗口注册类函数。3. WNDCLASSEX和WNDCLASS这两种窗口数据结构的成员中，hbrBackground，lpszMenuName，这三个成员的作用是什么，
