Save report

I created an table in database Firebird to save report??s (*.FRF) in field
kind BLOB. The problem is that it save just half of the report and when
i load again it show message of the error...

Anybody know if i can save the report how ASC? I think that it save kind
STREAM, but give error above...

thanks

    Hi
    first is the table structure to save the .frf file

    firstfield must be integer "repid",2nd field must be a blobfield "repdef" another fields can follow.
    you must hook into the designer components onsave event as described in faq.txt file.
    You will probably reed to create a customdialog to handle the choice of overwriting an existing report record or creating a new one.

    procedure TForm1.frDesigner1SaveReport(Report: TfrReport;
    var ReportName: String; SaveAs: Boolean; var Saved: Boolean);
    begin
    if SaveAs then
    with saverepdlg do
    begin
    Saved := ShowModal = mrOk;
    if Saved and not bloverwrite then
    begin
    repdm.TblRepdef.active := true;
    repdm.tblrepdef.edit;
    repdm.tblrepdef.insert;
    repdm.TblRepdefrepid.value := intrepno +1;
    repdm.TblRepdefDescription.Value := strrepname;
    Report.SaveToBlobField(repdm.tblrepdefrepdef);
    ReportName := strrepname;
    repdm.TblRepdef.Post;
    form1.blrepsaved := true;
    end;// end ifsavedand not overwrite
    if saved and bloverwrite then
    begin
    repdm.TblRepdef.active := true;
    repdm.TblRepdef.FindKey([intrepno]);
    repdm.TblRepdef.edit;
    repdm.tblrepdefrepdef.clear;
    Report.SaveToBlobField(repdm.tblrepdefrepdef);
    repdm.TblRepdefDescription.Value := strrepname;
    repdm.TblRepdef.Post;
    form1.blrepsaved := true;
    end;
    end
    else

    showmessage('save cancelled');
    repdm.TblRepdef.Active := false;
    end; // endpro

    some database engines may require a blob column.

    to load and display report

    procedure TForm1.Button1Click(Sender: TObject);
    begin
    repdm.TblRepdef.Active := true;
    frreport1.clear;
    frreport1.FileName := repdm.TblRepdefDescription.value +'.frf';
    frreport1.LoadFromBlobField(repdm.tblrepdefrepdef);
    frreport1.showreport;
    end;

    hope this helps
    regards
    gord ;)
