How to tell if a report has actually been printed?

edited July 2017 in General
Hi Team,
Given the following code..
{code}
with ReportsFrm.ReportsForm do
begin
ppRE1.LoadReport('Tax Quote', 2);
ppR1.ShowAutoSearchDialog := False;
ppR1.AutoSearchFields[0].SearchExpression := sJobNo;
ppR1.Print;
end;
{code}

Where/how can I tell if the 'report' has actually been printed rather than just viewed and closed?

Regards & TIA,
Ian

    Hi Ian,

    Take a look at the following article on how to detect if the report has
    been printed to the printer.

    Hi Nico,
    Thanks for the pointer and I suspect it will do the job however it doesn't seem to work in my configuration..
    To clarify further..
    1. Win 10, D10.2, latest RB.
    2. ppR1 and associated components, designer, explorer, etc are in what is in effect the end-user form.
    ReportsFrm.ReportsForm.
    3. The calling code, shown in the previous message, is in another form, both part of the main App. MainForm.
    4. The prints are always previewed before manually printing. This is to allow a final check that all details are
    correct.
    5. I added the "if ppR1.PrinterDevice <> nil then ShowMessage('Report was printed to the printer');" to the
    TReportsForm.ppR1AfterPrint(Sender: TObject);. IIUC it should show whenever anything is actually printed by ppR1.

    Unfortunately it doesn't. Not sure at what time after printing the routine is called but using F4 to trace to the
    AfterPrint procedure, it never gets there.

    Thoughts?

    Hi Ian,

    Looking at your initial message it appears you are perhaps loading
    templates. If so, you are loosing the event reference when the template
    is loaded.

    http://www.digital-metaphors.com/rbWiki/Design/Templates/How_To...Troubleshoot_Lost_Event_Handlers

    One solution is to use RAP. Another is to assign the event handler
    after the report has been loaded.

    Hi Nico,
    Again, thanks for the pointer.

    I ended up with a version of the following.....

    {code}
    ...
    ...
    procedure TJobTicketsForm.ReportPrinted(Sender: TObject);
    begin
    if ReportsFrm.ReportsForm.ppR1.PrinterDevice <> nil then ShowMessage('Report was printed to the printer');
    end;

    ...
    ...
    with ReportsFrm.ReportsForm do
    begin
    ppRE1.LoadReport('Sales Invoice', 2);
    ppR1.ShowAutoSearchDialog := False;
    ppR1.AutoSearchFields[0].SearchExpression := sJobNo;
    ppR1.AfterPrint := ReportPrinted;
    ppR1.Print;
    end;
    ...
    ..
    {code}

    Works perfectly thank you.

    Regards,
    Ian

    You might want to extend that a bit...

    In a couple of my applications it's essential that a report was fully
    printed, and actually went to a printer:


    //---EJB---2005.08.28-----------------------------
    procedure TfrmRepPSIView.ppReport1PrintDialogClose(Sender: TObject);
    begin
    // we accept only snet to printer, but NOT if printtofile
    FSentToPrinter:= ( (ppReport1.PrintDialog.DeviceType='Printer') and
    not (ppReport1.PrintDialog.PrintToArchive) and
    not (ppReport1.PrintDialog.PrintToFile)
    );
    end;




    And it had to be the complete range of pages:


    //---EJB---2005.08.29-----------------------------
    function TfrmRepPSIView.WasSentToPrinterEx: Boolean;
    begin
    // not only sent to printer, but EVERYTHING sent to printer
    result:=(FSentToPrinter and (FPgSetting=psAll) and (FPgRange=prAll));
    end;


    Here's where I populate FPgSetting and FPgRange...


    FPgSetting : TppPageSettingType;
    FPgRange : TppPageRangeType;

    //---EJB---2005.08.28-----------------------------
    procedure TfrmRepPSIView.ResetPrintStateFlags;
    // call before starting a print job
    begin
    FPgSetting := psFirstPage; // force to anything but "all" so we
    default to false
    FPgRange := prOddPages; // force to anything but "all" so we
    default to false
    FUserCancelled := False; // assume print not cancel
    FSentToPrinter := False; // assume not sent to printer
    end;

    //---EJB---2005.08.29-----------------------------
    procedure TfrmRepPSIView.ppReport1PageRequest(Sender,
    aPageRequest: TObject);
    begin
    if Assigned(ppReport1.PrintDialog) then begin
    FPgSetting:= TppPageRequest( aPageRequest ).PageSetting;
    FPgRange := TppPageRequest( aPageRequest ).PageRange;
    end;
    end;

    NP...

    I don't recall if it was Nard or Nico who helped me sort that out a
    dozen years ago, but I'm very happy to share it.

    I should add that it has worked (unchanged) in every version of RB from
    2005 to the latest ver 18.

    I love non-breaking upgrades!
