这个报错该怎么解决
gaodp 2002-06-23 03:45:55 各位前辈:
我现在正学编程。可一开始就给难住了。情况是这样的:
我学习的是《windows 程序设计》第5版。因为刚拿到书不久,所以还没有仔细看,就忙着上机做试验。第三章的试验hellowin.c 这个例程, 我照着编完以后,编译时没有报错,但是当我进行“构建hellowin.exe"时报出了以下的错误:
--------------------Configuration: hellowin - Win32 Debug--------------------
Linking...
hellowin.obj : error LNK2001: unresolved external symbol __imp__PlaySoundA@12
Debug/hellowin.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
hellowin.exe - 2 error(s), 0 warning(s)
开始我以为是我编写时,可能什么地方因为粗心了,输入错误,于是在栓查不出来的情况下把原程序给拷了去,再进行构建时还是以上的错误。
我有msdn.但是我的英文阅读能力太差了,越看我头越大。所以就来让前辈们指点一下。
我用的编程工具是 VC++6.0版 。完整的例程如下:
/*------------------------------------------------------------

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 ;

switch (message)
{
case WM_CREATE:

return 0 ;
case WM_PAINT:
hdc = BeginPaint (hwnd, &ps) ;
GetClientRect (hwnd, &rect) ;
DrawText (hdc, TEXT ("Hello, Windows 98!"), -1, &rect,

EndPaint (hwnd, &ps) ;
return 0 ;
case WM_DESTROY:
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
}
我第一次参加csdn,不知道怎么散分。在这里只有先谢过各位前辈了。
