windows程序设计示例：
1 #include "windows.h" 2 #pragma comment(lib, "winmm") 3 4 LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM); 5 6 int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) 7 { 8 static TCHAR szAppName[] = TEXT("HELLO WIN"); 9 HWND hwnd; 10 MSG msg; 11 WNDCLASS wndclass; 12 13 wndclass.style = CS_HREDRAW | CS_VREDRAW; 14 wndclass.lpfnWndProc = WndProc; 15 wndclass.cbClsExtra = 0; 16 wndclass.cbWndExtra = 0; 17 wndclass.hInstance = hInstance; 18 wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION); 19 wndclass.hCursor = LoadCursor(NULL, IDC_HAND); 20 wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH); 21 wndclass.lpszMenuName = NULL; 22 wndclass.lpszClassName = szAppName; 23 24 if (!RegisterClass(&wndclass)) 25 { 26 MessageBox(NULL, TEXT("ERROR"), TEXT(szAppName), MB_ICONERROR); 27 return 0; 28 } 29 30 hwnd = CreateWindow(szAppName, 31 TEXT("HELLO WORLD"), 32 WS_OVERLAPPEDWINDOW, 33 CW_USEDEFAULT, 34 CW_USEDEFAULT, 35 640, 36 480, 37 NULL, 38 NULL, 39 hInstance, 40 NULL); 41 ShowWindow(hwnd, iCmdShow); 42 UpdateWindow(hwnd); 43 44 while (GetMessage(&msg,NULL,0,0)) 45 { 46 TranslateMessage(&msg); 47 DispatchMessage(&msg); 48 } 49 50 return msg.wParam; 51 } 52 53 LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wparam, LPARAM lparam) 54 { 55 HDC hdc; 56 PAINTSTRUCT ps; 57 RECT rect; 58 59 switch (message) 60 { 61 case WM_CREATE: 62 PlaySound(TEXT("hellowin.wav"), NULL, SND_FILENAME | SND_ASYNC); 63 return 0; 64 case WM_PAINT: 65 hdc = BeginPaint(hwnd, &ps); 66 GetClientRect(hwnd, &rect); 67 DrawText(hdc, TEXT("HELLO WIN8"), -1, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER); 68 EndPaint(hwnd, &ps); 69 return 0; 70 case WM_DESTROY: 71 PostQuitMessage(0); 72 return 0; 73 } 74 return DefWindowProc(hwnd, message, wparam, lparam); 75 }
创建步骤：
1.创建一个WNDCLASS结构体
2.使用RegisterClass注册结构体
3.调用CreateWindow创建窗体并将句柄赋值给一个HWND结构体
4.调用ShowWindow显示窗体
5.调用UpdateWindow更新窗体
6.执行消息循环，使用GetMessage获取消息，使用TranslateMessage转换消息，使用DispatchMessage分发消息
PS:
如果不加#pragma comment(lib, "winmm")，会报错
错误 1 error LNK2019: 无法解析的外部符号 __imp__PlaySoundA@12，该符号在函数 _WndProc@16 中被引用 E:ProjectCWinCWinmain.obj CWin
另外一种解决方法，项目-属性-链接器-输入-附加依赖项中添加winmm.lib
原因：调用了一个多媒体函数，而多媒体对象库并未包含在默认项目内
