求救：关于链接错误如何解决？

编译通过了
链接的时候出现下面的错误：

afxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Debug/t1.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

是运行环境设置出问题了吗？
vc++6.0 建立一个win32程序。
到底有哪些地方要重新设置啊？
源程序在下面
只有一个主程序：如下

#include <afxwin.h>
class CSecondApp:public CWinApp
{
public:
virtual BOOL InitInstance();
};

class CSecondWindow:public CFrameWnd
{
public:
CSecondWindow();

DECLARE_MESSAGE_MAP()
public:
void OnPaint();

};

CSecondWindow::CSecondWindow()
{
Create(NULL,"WHERE ARE YOU,QIULIANG?");
}

BOOL CSecondApp::InitInstance()
{
m_pMainWnd=new CSecondWindow;
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return TRUE;
}

BEGIN_MESSAGE_MAP(CSecondWindow,CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()

void CSecondWindow::OnPaint()
{
PAINTSTRUCT ps;
HDC hdc;
hdc=::BeginPaint(m_hWnd,&ps);
::TextOut(hdc,100,100,"Where are you,QiuLiang!",lstrlen("Where are you,QiuLiang!"));
::EndPaint(m_hWnd,&ps);

}
CSecondApp ooapp;
