一个简单链接错误

nafxcwd.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex

helloKity.exe - 3 error(s), 0 warning(s)
Build的时候出现以上错误，我的程序很简单，如下
#include<afxwin.h>
#include"Hello.h"
CMyApp myApp;
BOOL CMyApp::InitInstance()
{
m_pMainWnd = new CMainWindow;
m_pMainWnd->ShowWindow(m_nCmdShow);
m_pMainWnd->UpdateWindow();
return TRUE;
}
BEGIN_MESSAGE_MAP(CMainWindow,CFrameWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()
CMainWindow::CMainWindow()
{
Create(NULL,_T("The hello kitty"));
}
void CMainWindow::OnPaint()
{
CPaintDC dc(this);
CRect rect;
GetClientRect(&rect);
dc.DrawText(_T("hello MFC"),-1,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);
}
头文件
class CMyApp:public CWinApp
{
public:
virtual BOOL InitInstance();
};
class CMainWindow:public CFrameWnd
{
public:
CMainWindow();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP();
};

编译是没问题的，链接出这个错误是什么意思，各位高手给我看看，多谢

[晨星]

是不是新建了一个Console工程确拷贝了一段非Console的代码过来编译？

[Yofoo]

代码生成要用 多线程 MT 或 MTD

[ayaya066]

MT或MTD是什么意思呢？

[ayaya066]

我用多线程DLL结果出来

[mr.zhoux]

project--> settings --> c/c++ -->project options 添加 /mt 或 MTD 支持多线程

[Yofoo]

不要用多线程DLL(MDD)

直接用多线程(MT) 或者 多线程调试(MTD(Debug方式))

[ayaya066]

顺便问问，这两种方式分别代表什么呢
