Serializing All Data in a Window into XML

Environment: Visual C++ 6.0 SP4 Windows 2000

Create an empty Visual C++ 6.0 dialog-based application using the MFC wizard. Add as many different controls as possible to the application (include edit boxes, drop down list controls, check boxes, radio buttons, date control, etc.).

Add a button called IDC_SERIALIZE and double-click on it to add the function below. Compile, run and fill in random data. When you click the serialize button, the application will get all data filled from all the controls and copy them into a CString that gets displayed. This is very useful for those times when you need to capture all data in a window.

Note: This method does not handle all the different control types available.

void CTestDlg::OnSerialize() 
{
  int nCount = 0;
  CString csText, csXMLReport;
  CWnd* pWndInitial = GetFocus();
  CWnd* pWnd = pWndInitial;
  char Name[51];

  csXMLReport = "<?xml version='1.0'?>\n";
  csXMLReport +=
     "<report xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>\n";
  ::SendMessage(this->m_hWnd, WM_NEXTDLGCTL, 0, 0);
  pWnd = GetFocus();
  GetClassName(pWnd->m_hWnd, Name, 50);

  while (pWnd != pWndInitial)
  {
    pWnd->GetWindowText(csText);
    csText.TrimLeft();

    if (strcmp(Name,"Button") == 0)
    {
      if (IsDlgButtonChecked(pWnd->GetDlgCtrlID()))
      {
        csXMLReport += "<" + csText + ">";
        csXMLReport += "1";
        csXMLReport += "</" + csText + ">\n";
      }
      else
      {
        CheckDlgButton(pWnd->GetDlgCtrlID(), BST_CHECKED);

        if (IsDlgButtonChecked(pWnd->GetDlgCtrlID()))
        {
          csXMLReport += "<" + csText + ">";
          csXMLReport += "0";
          csXMLReport += "</" + csText + ">\n";
        }
      }
    }
    else if (strcmp(Name,"Edit") == 0)
    {
      if (csText == "")
        csText = "NULL";

      csXMLReport += "<" + csText + "/>\n";
    }
    else if (strcmp(Name,"SysDateTimePick32") == 0)
    {
      csXMLReport += "<Date>" + csText + "</Date>\n";
    }

    ::SendMessage(this->m_hWnd, WM_NEXTDLGCTL, 0, 0);
    pWnd = GetFocus();
    GetClassName(pWnd->m_hWnd, Name, 50);
  }

  csXMLReport += "</report>";
  MessageBox(csXMLReport, MB_OK, NULL);
}

  • With JRebel, developers get to see their code changes immediately, fine-tune their code with incremental changes, debug, explore and deploy their code with ease (both locally and remotely), and ultimately spend more time coding instead of waiting for the dreaded application redeploy to finish. Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.

  • Live Event Date: May 6, 2014 @ 1:00 p.m. ET / 10:00 a.m. PT While you likely have very good reasons for remaining on WinXP after end of support -- an estimated 20-30% of worldwide devices still are -- the bottom line is your security risk is now significant. In the absence of security patches, attackers will certainly turn their attention to this new opportunity. Join Lumension Vice President Paul Zimski in this one-hour webcast to discuss risk and, more importantly, 5 pragmatic risk mitigation techniques …
