PDF / Windows 10 generates blanc pages/error reading pdf.

rbuser

Good morning,

My customer can not save reports as pdf since he has installed Windows 10.
I am using Version 16.02 Build 144

Adobe Acrobat Reader gives error 14, (version 2015.009.20079)

Is there something I have to change ?

kind regards,

Dirk Janssens.

Pretty sure this is caused by Windows update KB3102429 and for the short
term your customer should probably uninstall it. See something like

Hi Dirk,

If possible please send a copy of the invalid PDF file to
support@digital-metaphors.com so we can research the problem.

Thanks Paul,

This is very interesting. I have never seen something like this caused
by an Windows update. The PDF device does use a number of Windows API
calls for font processing so if the update broke any of that
functionality, it is possible that it is the cause of the problem.

I will research this further and see if this is the case.

Hello Nico,

We did some research : The update was not installed on the PC.

What is more interesting : the *only* difference between the 'blanc' pdf,
and the correct one, is the windows 10 user account.
So : user 1 - no problems, user 2 -> blanc pdf's.

I sent you the 2 pdf's for further analyses, and hope you can figure out
what is happening.

kind regards,

Dirk Janssens,.

Hi Dirk,

We received your email and this is a different issue. To solve the
problem, you need to keep the RB ppFormatSettings equal to the Delphi
FormatSettings when you change it in code.

uses
ppUtils;

FormatSettings.DecimalSeparator := ',';
ppFormatSettings := FormatSettings;
