PDF's not Created When the Application is Launched from a Service

Mon Oct 16, 2017 9:33 am

PXC6::IPXCPrinterPtr is not creating PDF files when the application is launched from a service. The same application launched with the same command line from a command prompt creates PDF's as expected. Are there a known issues using PDF-XChange from applications launched from services?

Hello steve.thresher,

I believe the drivers can not work in that way - but am awaiting a confirmation from our dev team.

Regards,
Stefan

Do you know how long it will take to get an answer from the developers?

If the printer cannot be used from a service then do you have any suggestions on how we can utilise the printer from an unattended process?

Can you please try if enabling the "Allow service to interact with desktop" option for your service solves the problem?

Thanks for the response. I've tried using my credentials for the service and that made no difference. I'll try the interact with desktop option and report back.

Hi Stefan,

Unfortunately the 'Allow desktop interaction' option has not fixed the problem. Basically my program is waiting for the PDF to be produced but the file never appears. The callstack for pdfSaver6.exe is as follows:

> win32u.dll!NtUserGetMessage() Unknown
user32.dll!GetMessageW() Unknown
pdfSaver6.exe!00007ff6cf9e09c1() Unknown
pdfSaver6.exe!00007ff6cf9e08b4() Unknown
pdfSaver6.exe!00007ff6cf9e1bc2() Unknown
pdfSaver6.exe!00007ff6cfbc6fe4() Unknown
kernel32.dll!BaseThreadInitThunk() Unknown
ntdll.dll!RtlUserThreadStart() Unknown

I had a copy of SysInternal's ProcessMonitor running at the time and I've attached a copy of the trace which includes all events from any process that contains pdf in the name. I'm out of ideas right now but I'm happy to run any diagnostic software you care to provide or I'm sure I can sort out remote access for your developers if that would help.

Kind regards
Steve.

Sorry to nag but I have several customers that are affected by this issue and they're starting to get quite impatient. Is there anything further I can try to get this solution working?
