关于LNK2019的错误求教

我在VC++下面debug里编译程序没有问题,但是在realse里面编译时出现了LNK2019的错误,错误如下:
 CDPlayer error LNK2019: unresolved external symbol __imp__mciGetErrorStringA@12 referenced in function "void __cdecl ErrorProc(unsigned long)" (?ErrorProc@@YAXK@Z)
CDPlayer error LNK2019: unresolved external symbol __imp__mciSendCommandA@16 referenced in function "public: long __thiscall CPlayer::Open(void)" (?Open@CPlayer@@QAEJXZ)

ErrorProc代码如下:
 void ErrorProc(MCIERROR dwResult)
{

     HANDLE hMem;
     LPSTR lpStringBuff;

     hMem=GlobalAlloc(GHND,80);

     if (hMem)
 {
  lpStringBuff=(char *)GlobalLock(hMem);
  if (lpStringBuff)
{
if(mciGetErrorString(dwResult,lpStringBuff,80))
      MessageBox(NULL,lpStringBuff,"ERROR",MB_OK);
else
      MessageBox(NULL,"Generic Error","ERROR",MB_OK);

GlobalUnlock(hMem);
}
  else
MessageBox(NULL,"Lock Failed","ERROR",MB_OK);

   GlobalFree(hMem);
 }
else
   MessageBox(NULL,"Alloc Failed","ERROR",MB_OK);

return ;
}

这应该是链接库没放到release的link里面

肯定是只在Debug设置里加了，忘了Release。

是winmm.lib没有在release里面加上.谢谢了

#pragma comment(lib ,\"winmm\")

#pragma comment(lib ,\"winmm\")

我比较喜欢用这种方法.....

wowocock还在驱动版里混啊,换工作了没有啊
