How can I display Crystal XI reports inside a Delphi 2007 application?

...
uses
  CrystalActiveXReportViewerLib11_5_TLB, OleAuto;
...

procedure TForm1.Button1Click(Sender: TObject);
var
  cry : TCrystalActiveXReportViewer;
  oRpt, oApp : variant;
  i : integer;
  frm : TForm;
begin
  cry := TCrystalActiveXReportViewer.Create(Self);
  oApp := CreateOleObject('CrystalRuntime.Application');
  oRpt := oApp.OpenReport('c:my_report.rpt',1);
  for i := 1 to oRpt.Database.Tables.Count do begin
    oRpt.Database.Tables[i].ConnectionProperties.Item['User ID'] := 'username';
    oRpt.Database.Tables[i].ConnectionProperties.Item['Password'] := 'password';
  end;

  frm := TForm.Create(Self);
  try
    cry.Parent := frm;
    cry.Align := alClient;
    cry.ReportSource := oRpt;
    cry.ViewReport;
    frm.Position := poOwnerFormCenter;
    frm.ShowModal;
  finally
    FreeAndNil(frm);
  end;  //try-finally
end;

procedure TForm1.btnExportClick(Sender: TObject);
var
  cry : TCrystalActiveXReportViewer;
  oRpt, oApp : variant;
  i : integer;
begin
  //Export the report to a file
  cry := TCrystalActiveXReportViewer.Create(Self);
  oApp := CreateOleObject('CrystalRuntime.Application');
  oRpt := oApp.OpenReport(c_DBRpt,1);
  for i := 1 to oRpt.Database.Tables.Count do begin
    oRpt.Database.Tables[i].ConnectionProperties.Item['User ID'] := 'username';
    oRpt.Database.Tables[i].ConnectionProperties.Item['Password'] := 'password';
  end;

  oRpt.ExportOptions.FormatType := 29;  //excel 8
  oRpt.ExportOptions.DiskFileName := 'c:output.xls';
  oRpt.ExportOptions.DestinationType := 1;  //file destination
  //Export(False) => do NOT prompt.
  //Export(True) will give runtime prompts for export options.
  oRpt.Export(False);
end;

Class to facilitate the display of Crystal 11 Reports.

The Crystal 11 VCL component does not seem to work with Delphi 2007.
As a result, we have to use ActiveX objects, which make deployment messy.

This class is similar to CrystalReporter, but it works for Crystal 11.
However, it lacks some of the features of the old CrystalReporter.

Refer to the crystal reports activex technical reference to duplicate the
missing functionality.

Example usage is at the bottom of this unit.

      Some reports use direct connections, and others use an ODBC Data Source.
      Crystal XI uses a different label to refer to the database name in each
      method.
      I don't know how to determine in advance which method is being used, so:
          First, we try the direct connection.
          If that fails, we try the "data source" method.
