VC：文件串行化（CFileDialog类、CFile类、CArchive类、Edit控件）

1、串行化：

void CArFileDlg::Serialize(CArchive& ar)

{

       if (ar.IsStoring())

       {     // storing code

              UpdateData(true);

              ar<<m_add;

              ar<<m_age;

              ar<<m_name;

              ar<<m_sex;

              ar<<m_tel;

       }

       else

       {     // loading code

              ar>>m_add;

              ar>>m_age;

              ar>>m_name;

              ar>>m_sex;

              ar>>m_tel;

              UpdateData(false);

       }

}

2、联系CFile对象：

void CArFileDlg::OnSave()

{

       // TODO: Add your control notification handler code here

       static char sfile[]="自定义类型(*.mm)|*.mm";//文件过滤

       CFileDialog dlg(FALSE,"mm","",NULL,sfile);//文件保存对话框对象

       if(IDOK==dlg.DoModal())

       {

              CFile myfile(dlg.GetFileName(),CFile::modeCreate|CFile::modeReadWrite);

              CArchive savefile(&myfile,CArchive::store);//CArchive对象

              Serialize(savefile);

              savefile.Close();

              AfxMessageBox("保存成功！");

       }

       //CDialog::OnOK();

       /*

              UpdateData(true);

       //对输入数据进行合法性检查

       int len1=m_id.GetLength();

       int len2=m_name.GetLength();

       if(len1>10||len2>10||len1==0||len2==0)

       {

              AfxMessageBox("输入字符不大于10,且不能为空");

              return;

       }

       char *p_id=new char[10];     //记录学号

       char *p_name=new char[10]; //记录姓名

       char *p_score=new char[3];   //记录成绩

       memset(p_id,'\0',10);

       memset(p_name,'\0',10);

       memset(p_score,'\0',3);

       _tcscpy(p_id,m_id);

       _tcscpy(p_name,m_name);

       itoa(m_score,p_score,10);

       CFile file;

       file.Open("test.txt",CFile::modeCreate|CFile::modeReadWrite);

       file.SeekToEnd();

       file.Write(p_id,10);

       file.Write(p_name,10);

       file.Write(p_score,3);

       file.Close();

       delete p_id;

       delete p_name;

       delete p_score;

       AfxMessageBox("保存成功");

 

  */

}

 

void CArFileDlg::OnOpen()

{

       // TODO: Add your control notification handler code here

       static char sfile[]="自定义类型(*.mm)|*.mm";//文件过滤

       CFileDialog dlg(TRUE,"mm","",NULL,sfile);//文件保存对话框对象

       if(IDOK==dlg.DoModal())

       {

              CFile myfile(dlg.GetFileName(),CFile::modeReadWrite);

              CArchive savefile(&myfile,CArchive::load);//CArchive对象

              Serialize(savefile);

              savefile.Close();

              GetDlgItem(IDC_NAME)->EnableWindow(FALSE);

              GetDlgItem(IDC_AGE)->EnableWindow(FALSE);

              GetDlgItem(IDC_SEX)->EnableWindow(FALSE);

              GetDlgItem(IDC_TEL)->EnableWindow(FALSE);

              GetDlgItem(IDC_ADD)->EnableWindow(FALSE);

       }

              //     CDialog::OnOK();

}
