LINK时出错！

[ML20]

//Hello.h
class CMyApp:public CWinApp{
public:
virtual BOOL InitInstance();
};

class CMainWindow:public CFrameWnd{
public:
CMainWindow();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()
};
//Hello.cpp
#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 Application"));
}

void CMainWindow::OnPaint(){
CPaintDC dc(this);
CRect rect;
GetClientRect(&rect);
dc.DrawText(_T("Hello,MFC"),-1,&rect,
DT_SINGLELINE|DT_CENTER|DT_VCENTER);
}
结果连接时出错，以下是错误信息，请问这是怎么一回事？我该怎么做？

#include <process.h>

[zswzwy]

不行在加入
LIBCMT.LIB
MSVCRT.LIB

[yuanquana]

据说这种错误不好整的。

[zswzwy]

setting->link->LIBCMT.LIB
setting->link->MSVCRT.LIB

[ML20]

好的，我试试

还是不对。

[DoubleJiang]

你有没有用VC 的 Wiazrd

[Mutu20]

还是别学VC了。
