文件貌似不能正确读！！！

Question

   下面是我的读写文件代码，改了半天，还是不行，刚学，起步真的很难啊，还请大虾们指点！！！
PZinfor *PPZinfor=new PZinfor();


PPZinfor->SliderPos=m_slider.GetPos();

PPZinfor->Combo1Pos=m_combo1.GetCurSel();
PPZinfor->Combo2Pos=m_combo2.GetCurSel();
PPZinfor->Combo3Pos=m_combo3.GetCurSel();

    PPZinfor->checkpos1=((CButton *)GetDlgItem(IDC_CHECK1))->GetCheck();
PPZinfor->checkpos2=((CButton *)GetDlgItem(IDC_CHECK2))->GetCheck();
PPZinfor->checkpos3=((CButton *)GetDlgItem(IDC_CHECK3))->GetCheck();
PPZinfor->checkpos4=((CButton *)GetDlgItem(IDC_CHECK4))->GetCheck();
PPZinfor->checkpos5=((CButton *)GetDlgItem(IDC_CHECK5))->GetCheck();
PPZinfor->checkpos6=((CButton *)GetDlgItem(IDC_CHECK6))->GetCheck();

PPZinfor->RadioPos1=((CButton *)GetDlgItem(IDC_RADIO1))->GetCheck();
PPZinfor->RadioPos2=((CButton *)GetDlgItem(IDC_RADIO2))->GetCheck();
CFile MyFile;
MyFile.Open(_T(".\\MyInfor.txt"),CFile::modeCreate|CFile::modeWrite);
MyFile.Write(&PPZinfor,sizeof(PZinfor));
MyFile.Close();
delete PPZinfor; PZinfor *PPZinfor=new PZinfor();
      CFile MyFile;
      CFileFind filefind;
   if(filefind.FindFile(".\\MyInfor.txt"))
      {
   MyFile.Open(_T(".\\MyInfor.txt"),CFile::modeRead);
        MyFile.Read(&PPZinfor,sizeof(PZinfor));
  
        m_slider.SetPos(PPZinfor->SliderPos);
   
    m_combo1.SetTopIndex(PPZinfor->Combo1Pos);
    m_combo2.SetTopIndex(PPZinfor->Combo2Pos);
     m_combo3.SetTopIndex(PPZinfor->Combo3Pos);
   
     ((CButton *)GetDlgItem(IDC_CHECK1))->SetCheck(PPZinfor->checkpos1);
        ((CButton *)GetDlgItem(IDC_CHECK2))->SetCheck(PPZinfor->checkpos2);
    ((CButton *)GetDlgItem(IDC_CHECK3))->SetCheck(PPZinfor->checkpos3);
    ((CButton *)GetDlgItem(IDC_CHECK4))->SetCheck(PPZinfor->checkpos4);
((CButton *)GetDlgItem(IDC_CHECK5))->SetCheck(PPZinfor->checkpos5);
     ((CButton *)GetDlgItem(IDC_CHECK6))->SetCheck(PPZinfor->checkpos6);
   
        ((CButton *)GetDlgItem(IDC_RADIO1))->SetCheck(PPZinfor->RadioPos1);
     ((CButton *)GetDlgItem(IDC_RADIO2))->SetCheck(PPZinfor->RadioPos2);
  
        MyFile.Close();
      }

Answer 1

哪不行,代码上通不过,还是结果跟想像中的不同?读文件最好用CStdioFile类有空结贴,结贴率太低了

Answer 2

首先重申下一楼的批评，结贴率低的帖子别人都不想回答。那你问问题就没意义了其次是你的错误，你没有分清指针的地址和指针所指向的地址的区别PZinfor *PPZinfor=new PZinfor();// 这句中的PZinfor，他所指向的地址空间为一个PZinfor，大小为sizeof（PZinfor）
                                      //但是他自身的地址&PZinfor，空间大小为sizeof(PZinfor);为一个指针的大小，非所指向空间，楼主你搞错了PZinfor *PPZinfor=new PZinfor(); 
PPZinfor->SliderPos=m_slider.GetPos(); PPZinfor->Combo1Pos=m_combo1.GetCurSel(); 
PPZinfor->Combo2Pos=m_combo2.GetCurSel(); 
PPZinfor->Combo3Pos=m_combo3.GetCurSel();     PPZinfor->checkpos1=((CButton *)GetDlgItem(IDC_CHECK1))->GetCheck(); 
PPZinfor->checkpos2=((CButton *)GetDlgItem(IDC_CHECK2))->GetCheck(); 
PPZinfor->checkpos3=((CButton *)GetDlgItem(IDC_CHECK3))->GetCheck(); 
PPZinfor->checkpos4=((CButton *)GetDlgItem(IDC_CHECK4))->GetCheck(); 
PPZinfor->checkpos5=((CButton *)GetDlgItem(IDC_CHECK5))->GetCheck(); 
PPZinfor->checkpos6=((CButton *)GetDlgItem(IDC_CHECK6))->GetCheck(); PPZinfor->RadioPos1=((CButton *)GetDlgItem(IDC_RADIO1))->GetCheck(); 
PPZinfor->RadioPos2=((CButton *)GetDlgItem(IDC_RADIO2))->GetCheck(); 
CFile MyFile; 
MyFile.Open(_T(".\\MyInfor.txt"),CFile::modeCreate|CFile::modeWrite); 
MyFile.Write(&PPZinfor,sizeof(PZinfor)); 
MyFile.Close(); 
delete PPZinfor; PZinfor *PPZinfor=new PZinfor(); 
      CFile MyFile; 
      CFileFind filefind; 
  if(filefind.FindFile(".\\MyInfor.txt")) 
      { 
  MyFile.Open(_T(".\\MyInfor.txt"),CFile::modeRead); 
        MyFile.Read(PPZinfor,sizeof(PZinfor));  //这样才对  
      m_slider.SetPos(PPZinfor->SliderPos); 
  
  m_combo1.SetTopIndex(PPZinfor->Combo1Pos); 
  m_combo2.SetTopIndex(PPZinfor->Combo2Pos); 
    m_combo3.SetTopIndex(PPZinfor->Combo3Pos); 
  
    ((CButton *)GetDlgItem(IDC_CHECK1))->SetCheck(PPZinfor->checkpos1); 
        ((CButton *)GetDlgItem(IDC_CHECK2))->SetCheck(PPZinfor->checkpos2); 
  ((CButton *)GetDlgItem(IDC_CHECK3))->SetCheck(PPZinfor->checkpos3); 
  ((CButton *)GetDlgItem(IDC_CHECK4))->SetCheck(PPZinfor->checkpos4); 
((CButton *)GetDlgItem(IDC_CHECK5))->SetCheck(PPZinfor->checkpos5); 
    ((CButton *)GetDlgItem(IDC_CHECK6))->SetCheck(PPZinfor->checkpos6); 
  
        ((CButton *)GetDlgItem(IDC_RADIO1))->SetCheck(PPZinfor->RadioPos1); 
    ((CButton *)GetDlgItem(IDC_RADIO2))->SetCheck(PPZinfor->RadioPos2); 
  
        MyFile.Close(); 
      }
