为什么会出现如这样的错误,但当编译的时候 没有错,#include<afxwin.h>
#include"hello.h"
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);
}

另外需要#include <process.h>。
class CMyApp:public CWinApp
{
public:
virtual BOOL InitInstance();
};
class CMainWindow:public CFrameWnd
{
public:
CMainWindow();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()
};
几位大哥,都接你们说的去做了,还是不行,
#pragma comment(linker, "/subsystem:Windows") //加上这两句看看#include <afxwin.h>
#include "hello.h"
............
2.请使用多线程版本的C\C++运行期函数库
project->settings
link tab
Project Options中找到
/subsystem:console
改为/subsystem:windows
