Changing page size in runtime

[guy.marom]

Hello,
I just installed and started testing the PDF-XChange 4 API and I need to be able to change the page size in runtime (And not the sheet size). Is that possible?

Thanks,
Guy Marom

Can you say paper size for any other printer in run-time ? Yes, and you will modify DEVMODE fields to do this. Why you cannot try to do the same with PDF-XChange ?

[guy.marom]

Could you please direct me to some sample code?
Thanks

Would this help?

MSDN DEVMODE (This structure contains information about a printer environment and device initialization.)

Regards,
Stefan

No sure how to use this, but thank you very much for the help. I really appreciate it.

appreciated.

I'm continuing this thread because I ran into a problem and I think other people might run into the same thing.

I can't seem to find the correct permissions to give the user running my application so that he will be able to change the printer settings. I keep getting a win32exception no. 5 (Access is denied) when I run the win32api method "OpenPrinter".
So far, making the user a local administrator on the machine is the only thing that worked but that's not very good...

Any ideas?

Can you send me you sample code? I will correct it, and send back.

I attached a wrapper class for the WIN32API the problem happens in the function GetPrinterSettings in row no. 184 (The return value in that row is 0, or False).
I attached all of it since it's what I got from the NET, if it's too much I'll try and make a "slimmer" version of the code.
Thanks

Sorry, I'm not so familiar with .NET, so, code is a bit ugly. By the way, it works.

[guy.marom]

I know it works, that's why I posted it here in the first place. I'm sure more people can use this.
My problem is with permissions, so far we can't figure out what is the minimal set of permissions needed in order to perform these operations.
We prefer not making the user an administrator for obvious reasons (At least they are obvious to our IT manager ).

I think part of the IT problem is that you printer driver creates temporary printers, so permissions on them cannot be given in advance.

Sorry, I didn't understand -- modified example I send you works or not?

[guy.marom]

Just tested it. It seems to be working fine.
Thank you very much

I guess I was a bit hasty to rejoice, it doesn't work...
So I dug into the Win32 API (You can find a reference at http://msdn.microsoft.com/en-us/library ... S.85).aspx) and fixed the code.

I used the PRINTER_INFO_9 structure, it is the structure that is used to change user specific printer options.
I noticed that it cannot be populated unless the PDF-XChange printer driver applies settings first - I mean using the ApplyOptions function of the printer driver.

Attached is the final version of the code I am currently using. Enjoy, and again thanks for all the help.
