请帮忙改个win32程序,书上的例子,却运行不了是怎么回事?
//在f盘上,有一个wav格式的文件,但是此程序编译无误,运行不了,刚学,望各位指点迷津

#include <windows.h>


LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;


int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,

PSTR szCmdLine, int iCmdShow)

{

static TCHAR szAppName[] = TEXT ("HELLO") ;

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, // window class name

TEXT ("The Hello Program"), // window caption

WS_OVERLAPPEDWINDOW, // window style

CW_USEDEFAULT,// initial x position

CW_USEDEFAULT,// initial y position

CW_USEDEFAULT,// initial x size

CW_USEDEFAULT,// initial y size

NULL, // parent window handle

NULL, // window menu handle

hInstance, // program instance handle

NULL) ; // creation parameters



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 ("F:\VC++\LIZI\HELLO.wav"), NULL, SND_FILENAME | SND_ASYNC) ;

return 0 ;


case WM_PAINT:

hdc = BeginPaint (hwnd, &ps) ;



GetClientRect (hwnd, &rect) ;



DrawText (hdc, TEXT ("Hello, Windows 98!"), -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) ;

}

[解决办法]
#include <mmsystem.h>
#pragma comment(lib,"winmm.lib")
[解决办法]
winmm.lib这个链接库是否加上了?

在菜单Project的最后一项,Additional Dependencies这样的一个选项上添加。
