VC++已实现横向输出，为什么一拉滚动条就变成竖向的了？

Question

void C路桥工程View::OnFileOpen()
{
 // TODO:  在此添加命令处理程序代码
 if (!sum1.empty())
 {
  sum1.clear();
 }

 CFileDialog fileDlg(TRUE);
 CString title1;
 title1 = "打开文件";
 CString filter1;
 filter1 = "Text Files(*.txt)";
 fileDlg.m_ofn.lpstrTitle = title1;
 fileDlg.m_ofn.lpstrFilter = filter1;
  
 if (IDOK == fileDlg.DoModal())
 {
  CFile file(fileDlg.GetFileName(), CFile::modeRead);
  char *pBuf;
  CString duzi1;
  DWORD dwFileLen;
  int wzcd1;
  dwFileLen = file.GetLength();
  wzcd1 = file.GetLength();
  pBuf = new char[dwFileLen + 1];
  pBuf[dwFileLen] = 0;
  file.Read(pBuf, dwFileLen);
  file.Close();
  MessageBox((CString)pBuf);

  duzi1 = pBuf;
  int number1=duzi1.GetLength();
  //char* array=new char(number1);
  CString array1;
  for(int i2=0;i2<number1;i2++)
  { 
   array1 = duzi1.GetAt(i2);//输出的字符
   sum1.push_back(array1);
  }
  
    
  CDC* pDC=GetDC();
  TEXTMETRIC tm2;
  pDC->GetTextMetrics(&tm2);
  int i1=0;
  int p1;
  int f1;
  int i3 = sum1.size();
  int p2 = 1024 / tm2.tmMaxCharWidth;
  int f2 = i3 / p2;
  while (i1 < i3)
  {
   for (f1 = 0; f1 < f2; f1++)
   {
    for (p1 = 0; p1 <= p2; p1++)
    {
     pDC->TextOut(tm2.tmMaxCharWidth*p1, tm2.tmHeight*f1, sum1[i1]);//横向输出
     i1++;
    }

   }
  }
  SetScrollSizes(MM_TEXT, CSize(1024, tm2.tmHeight*f1));
    
         
 }

}

您的代码中有处理WM_HSCROLL消息吗？ 建议您直接使用CEditView作为View类的基类，另外绘图的代码最好是放到OnDraw函数中。
