Corrupted pdf-files

rbuser

Hello,

we released a new version of our software that includes the latest
reportbuilder.
We have several customer complaining that saving a report to pdf gives
an empty pdf!
As we generate the pdf and send invoices to customers by mail, customers
receive empty invoices for the moment.
This is really painfull.
It seems to happen only once in a while, how can be fix this.
This is the code we are using:

if fileExists(ExtractFilepath(Application.exename) + 'tempfile.pdf')
then DeleteFile(ExtractFilepath(Application.exename) + 'tempfile.pdf');
report.ShowPrintDialog := False;
report.DeviceType := dtPDF;
report.PDFSettings.OpenPDFFile := False;
report.TextFileName := ExtractFilepath(Application.exename) +
'tempfile.pdf';
report.Print;

Problem is that I can't simulate it.
We get reports from customers, how can we get rid of this problem as
soon as possible.
Would downgroading to version 12.02 be a solution?
It has been working for over a year perfectly with version 11.08.
I can't downgroad to this version as the application contains over 300
reports that have been modified to the version 12 format.

The only thing I can send you is the content of the blob fields in the
database in pdf and raf format.
Is that something you can work with?

Thx,

Hi Bernaert,

Yes, you can send me the archive files of the reports that have the issue
and I can test them here. Please understand however that if I'm unable to
recreate the issue here, there is very little chance of tracking down the
problem. Any additional information about the users that are getting this
error would also be helpful.

Please send the example files in zip format to
support@digital-metaphors.com.

I have been this problem too. When I had reportbuilder 10.09 works. I get
12.04 and this problem begun.

Any ideas. I need a solution cause I have customers who use and they get
errs. I work with Delphi XE profession and ReportBuilder 12.04 Enterprise.
This problem happens just some PCs another works.

Hi everyone!

I have same problem here - empty pdf files. I work with Delphi and also
use ReportBuilder 12.04 Enterprise. But there is one thing I have
discovered on computers with windows7 and it seems to be related to
operating system's "Regional and Language options" settings.

In practice please can someone (one with empty pdf problem) try to
change "Current format" setting (in Regional and Language options) to
any other country, then apply settings, and then change it back to your
original country. I have found that this action resolves empty pdf
problem in every Windows 7 computer.

Some background information can be found here, please read, these
explain one windows7 bug that may appear with many applications
programmed with Delphi.

http://stackoverflow.com/questions/1767946/getthreadlocale-returns-different-value-than-getuserdefaultlcid

And more detailed:
http://blogs.msdn.com/b/michkap/archive/2010/03/19/9980203.aspx

To summarize: The relevant API calls all operate on registry values that
can be found at HKCU\Control Panel\International. The value "Locale" is
maintained for backward compatibility reasons and under normal
circumstances is kept in synch with its newer counterpart called
"LocaleName". This synch process however doesn't work under some
circumstances. Anyway, the GetThreadLocale API call gets its return
value from the "Locale" registry entry mentioned above, while the others
(GetUserDefaultLCID, GetSystemDefaultLCID, etc) use the "LocaleName"
registry entry.

Not every Windows7 has this situation , but many pre-installed
computers for european market have this problem.
So far I have not found any Delphi programming workaround for empty
pdf problem. That manual country change as described above is acctually
not convenient for clients.

All additional questions are welcome.

Hi Gunnar,

Starting with RB 12, it is now necessary to change the ppFormatSettings
global property each time you alter the Delphi global FormatSettings
values. Otherwise there is a possibility of getting empty PDF output.

For instance...

uses
ppUtils;

begin

DecimalSeparator := ',';
ThousandSeparator := '.';

ppFormatSettings.DecimalSeparator := DecimalSeparator;
ppFormatSettings.ThousandSeparator := ThousandSeparator;
