windows 编程课第一次作业

今天把书上的100行hello world代码打上去了，又下了vs2010，最后总算调试出来了

其中“PlaySound这个函数在Winmm.lib这个库中,当然需要链接它。”

所以其实是一直缺这一句话

#pragma comment(lib, "winmm")

#include<windows.h>#pragma comment(lib, "winmm")//playsound函数需要LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);//Wndproc窗口函数的原型说明int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)//入口函数{    //定义变量    static TCHAR szAppName[] = TEXT("Hello Win");    HWND hwnd;    MSG msg;    WNDCLASS wndclass;    wndclass.style = CS_HREDRAW | CS_VREDRAW;    wndclass.lpfnWndProc = WndProc;    wndclass.cbClsExtra = 0;    wndclass.cbWndExtra = 0;    wndclass.hInstance = hInstance;    wndclass.hIcon = LoadIcon(NULL,IDI_APPLICATION);    wndclass.hCursor = LoadCursor(NULL,IDC_ARROW);    wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);    wndclass.lpszMenuName = NULL;    wndclass.lpszClassName = szAppName;    if(!RegisterClass(&wndclass))    {        MessageBox(NULL,TEXT("This program requires Windows NT!"),                                szAppName,MB_ICONERROR);        return 0;    }    hwnd = CreateWindow(szAppName,            TEXT("Message from river"),            WS_OVERLAPPEDWINDOW,            CW_USEDEFAULT,            CW_USEDEFAULT,            CW_USEDEFAULT,            CW_USEDEFAULT,            NULL,            NULL,            hInstance,            NULL);    ShowWindow(hwnd,iCmdShow);    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){    HDC hdc;    PAINTSTRUCT ps;    RECT rect;    switch(message)    {    case WM_CREATE:        PlaySound(TEXT("hellowin.wav"),NULL,SND_FILENAME | SND_ASYNC);        return 0;    case WM_PAINT:        hdc = BeginPaint(hwnd,&ps);        GetClientRect(hwnd,&rect);        DrawText(hdc,TEXT("Hello, sweetie!"),-1,&rect,DT_SINGLELINE | DT_CENTER | DT_VCENTER);        EndPaint(hwnd,&ps);        return 0;    case WM_DESTROY:        PostQuitMessage(0);        return 0;    }    return DefWindowProc(hwnd,message,wParam,lParam);    }
