Empty pdf files

edited September 2012 in Devices
Hi everyone!

I have same problem with export to pdf.
I have an empty pdf files.
I work with Delphi 2010 and also
use ReportBuilder 12.05 Enterprise build 251.

I read, somewhere, that for computers with windows7 it seems to be
related to
operating system's "Regional and Language options" settings.

Is it true?

If is true, there is a patch or new release to fix this problem?

I have an important client waiting for a response to this problem.

Best Regards

    Hi Mauro,

    Starting with RB 12, if your application (at any time) alters the
    built-in Delphi FormatSettings, the ReportBuilder ppFormatSettings also
    need to be updated. The issues with PDF are generally caused by
    altering the FormatSettings.DecimalSeparator in code.

    You will want to add the following line in order to resolve the issue.

    FormatSettings.DecimalSeparator := ',';
    ppFormatSettings := FormatSettings; //Add this line

    Hi Nico,
    thanks for the reply, but this problem was solved with the 14.x without
    adding the line of code that I have indicated ?

    Best regards

    Hi Mauro,

    This is a requirement for all versions of ReportBuilder from RB 12 on.

    Hello Nico

    Forgive me for jumping in, but this is disastrous for us! We have to
    support multiple currencies in our app and we do this NOT by messing
    around with global formatting settings, but instead loading these
    settings from a table into a class that dynamically handles display
    formats in output like the DevExpress Grid or Report Builder reports. I
    have RAP pass-through procedures that can assign the Displayformat to
    any currency fields according to the currency type that applies to them
    and it works a treat. I also have a custom TppDisplayFormat class
    registered to handle more manual ways of specifying currency formats.

    This bit of news about PDF output is very bad indeed and tests show that
    PDF output is now broken if the currency being displayed doesn't match
    the global Delphi settings. Surely this is NOT the way to do it as it
    precludes the possibility of displaying more than one currency in a PDF
    output? Why can't the PDF engine just respect the DisplayFormat settings
    that have been assigned to each component on the report?

    I've put a lot of work into our model of currency formatting - please
    come back with something reassuring?

    TIA, Paul

    Paul,

    I'm a bit unclear about what exactly you are changing. If possible,
    please send a simple example showing this behavior to
    support@digital-metaphors.com in .zip format and I'll look at it for you.

    The only requirement here is to keep the global FormatSettings in sync
    with the ReportBuilder ppFormatSettings (specifically the decimal
    separator). All (numeric) text exported to the PDF device is sent
    through the TppPDFCanvas.ExtToStr routine. This automatically replaces
    the decimal separator (defined by ppFormatSettings.DecimalSeparator)
    with a period ".". If you change the global FormatSettings without also
    changing the ppFormatSettings you can see how this would cause issues.

    After re-reading your post, it appears this is a completely different
    issue. This thread addresses the "Empty PDF" issue when altering the
    FormatSettings global property. If you are able to see objects inside
    your exported PDF, this is a different problem.

    Please send a simple example to me and I'll research it for you.

    Nico, I think I may have been talking out of my $%£& having panicked
    over this and done some rather crude tests. I've been busy covering
    support myself today (!!!) so not had time to check this out properly.
    For the time being I please ignore this - I may have been making a fuss
    over nothing, in which case I apologize. I'll come back to you if I need to.

    Paul
