区段名修改工具（ChangeSectionName）的编写

殇桀

产生随机字符的代码：

• char CChangeSectionNameDlg::GetChar()

  {

  return (char)(rand()%92+33);

  }

主要功能实现代码：

• void CChangeSectionNameDlg::OnDo()

  {

  UpdateData(TRUE);

  if (m_bak == TRUE)

  {

    CString fn;

    fn = m_FileName + ".bak";

    CopyFile(m_FileName,fn,TRUE);

    fn.ReleaseBuffer();

  }

  CFile f;

  int secNum,n,m;

  IMAGE_DOS_HEADER dh;

  IMAGE_NT_HEADERS nh;

  IMAGE_SECTION_HEADER sh;

  f.Open(m_FileName,CFile::modeReadWrite);

  f.Read(&dh,sizeof(IMAGE_DOS_HEADER));

  f.Seek(dh.e_lfanew,CFile::begin);

  f.Read(&nh,sizeof(IMAGE_NT_HEADERS));

  secNum = nh.FileHeader.NumberOfSections;

  if (m_mode == 0)

  {

    for (n=0;n<secNum;n++)

    {

     f.Read(&sh,sizeof(IMAGE_SECTION_HEADER));

     for (m=0;m<8;m++)

     {

      sh.Name[m] = GetChar();

     }

     f.Seek(-sizeof(IMAGE_SECTION_HEADER),CFile::current);

     f.Write(&sh,sizeof(IMAGE_SECTION_HEADER));

    }

  }

  else if (m_mode == 1)

  {

    for (n=0;n<secNum;n++)

    {

     f.Read(&sh,sizeof(IMAGE_SECTION_HEADER));

     sh.Name[0] = 'z';

     sh.Name[1] = 'a';

     sh.Name[2] = 'p';

     sh.Name[3] = '.';

     for (m=4;m<8;m++)

     {

      sh.Name[m] = GetChar();

     }

     f.Seek(-sizeof(IMAGE_SECTION_HEADER),CFile::current);

     f.Write(&sh,sizeof(IMAGE_SECTION_HEADER));

    }

  }

  else

  {

    char xName[6][8] = {"zapline","zap.vm ","zap.crc",{'z','a','p','.','a','n','t','i'},"zapline",{'f','u','c','k','x','i','m','o'}};

    for (n=0;n<secNum;n++)

    {

     f.Read(&sh,sizeof(IMAGE_SECTION_HEADER));

     for (m=0;m<8;m++)

     {

      sh.Name[m] = xName[n][m];

     }

     f.Seek(-sizeof(IMAGE_SECTION_HEADER),CFile::current);

     f.Write(&sh,sizeof(IMAGE_SECTION_HEADER));

     if (n == 5)

     {

      break;

     }

    }

    for (n=5;n<secNum;n++)

    {

     f.Read(&sh,sizeof(IMAGE_SECTION_HEADER));

     for (m=0;m<8;m++)

     {

      sh.Name[m] = GetChar();

     }

     f.Seek(-sizeof(IMAGE_SECTION_HEADER),CFile::current);

     f.Write(&sh,sizeof(IMAGE_SECTION_HEADER));

    }

  }

  f.Close();

  MessageBox("OK!");

  }
