一个小问题！

Question

mfc版的各位朋友，大家好！小弟第一次到这儿来，先散100分，请各位接分（来者有分）顺便问一个关于hello，world程序的问题。我刚学完c++，就迫不及待地来到这儿。由于我学vc++都是自学的，以后可能会问一些超级菜问题，还请各位帮忙！另外我现在手头只有李久进的mfc深入浅出，电子版的vc++技术内幕，我准备买侯捷的mfc深入浅出。请各位给点建议！
我的问题如下：
class CMyApp:public CWinApp
{ public:
     virtual bool InitInstance();
};
class CMyFrame:public CFrameWnd
{ public:
     CMyFrame();
protected:
 afx_msg void OnLButtonDown(UINT nFlags,CPoint point);
 afx_msg void OnPaint();
 DECLARE_MESSAGE_MAP()
};  //这是myapp.h文件
#include <afxwin.h>
#include "myapp.h"
CMyApp theApp;
bool CMyApp::InitInstance()
{ m_pMainWnd=new CMyFrame();
  m_pMainWnd->ShowWindow(m_nCmdShow);
  m_pMainWnd->UpdateWindow();
  return true;
}
BEGIN_MESSAGE_MAP(CMyFrame,CFrameWnd)
ON_WM_LBUTTONDOWN()
ON_WM_PAINT()
END_MESSAGE_MAP()
CMyFrame::CMyFrame()
{ Create(NULL,"MYAPP Application");
}
void CMyFrame::OnLButtonSown(UINT nFlags,CPoint point)
{  TRACE("Entering CMyFrame::OnLButtonDown - %1x,%d,%d\n",(long)nFlags,point,x,pont.y);}
void CMyFrame::OnPaint()
{ CPaintDC dc(this);
  dx.TextOUt(0.0."Hello,World!");
}
这个程序有8个错误，哪位帮我改一下？谢了！

Answer 1

有几个输错了。现改正如下：
nFlags,point,x,pont.y);
该为nFlags,point.x,point.y);dx.TextOUt(0.0."Hello,World!");
改为dc.TextOUt(0，0，"Hello,World!");

Answer 2

dx.TextOUt(0.0."Hello,World!");  //这也错了吧
up
