Problem with opening PDF file

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

I've discovered that QuickPDF fails to open one PDF file (though PDF viewers are working OK on it). Here is my code:

                    PDFLibraryClass qp = new PDFLibraryClass();
int res = qp.UnlockKey(qpKey); // Passed OK
res = qp.LoadFromFile(strPDFPath); // Passed OK
int pageCount = qp.PageCount(); // Passed OK, pageCount = 8
byte[] quickPDFImage = (byte[])qp.RenderPageToVariant(150, pageNumber, 5); // Fails

Exception:
			System.Runtime.InteropServices.COMException (0x8000FFFF): Range check error
   at QuickPDFAX0712.PDFLibraryClass.RenderPageToVariant(Int32 DPI, Int32 Page, Int32 Options)
at Blueberry_PDF_Form_Filler.PDFDocument.RenderPage(Int32 pageNumber, Boolean bShowFormControls, Boolean bPreview) in C:\\dev\\Blueberry PDF Form Filler\\Blueberry PDF Form Filler\\PDFDocument.cs:line 579
at Blueberry_PDF_Form_Filler.PDFDocument.RenderPage(Int32 pageNumber) in C:\\dev\\Blueberry PDF Form Filler\\Blueberry PDF Form Filler\\PDFDocument.cs:line 672
   at Blueberry_PDF_Form_Filler.PDFDocument.ReadPDF() in C:\\dev\\Blueberry PDF Form Filler\\Blueberry PDF Form Filler\\PDFDocument.cs:line 249	

Here is PDF file:

Thanks in advance,
Mick.

	Hi Mick! With my app already built last autumn i don't have any problems with this file. I've seen that you're using CSharp... Please change the parameter values from Int32 to UInt32 - then it'll work for you i think. Additionally you should look here (the right side): http://www.quickpdflibrary.com/support/index.php Cheers, Ingo

	Hi Ingo, I think I can't change the type from Int32 to UInt32 - functions declarations are located in 'Interop.QuickPDFAX0712.dll' that is being generated automatically by Visual Studio when I add reference to 'QuickPDFAX0712.dll' ActiveX to my C# project. As for link given by you - I've tried to search in knowledge base for 'c#' and 'uint' keywords but failed to find anything related to my problem. What version of QuickPDF AciveX your program is using? Perhaps there is problem with newer version? My company bought version 7.12 and I'm not sure it's good idea to switch to older version. Regards, Mick.

	I don't use the activex-version. This here is a user-user-forum. If you need quick help from the authors you should post on the support-website i've posted in my message above. Perhaps changing to the newest version 7.14 can help, too. Cheers, Ingo

	Hi Mick, I've put together a small C# project which uses the RenderPageToVariant function and version 7.14 of the library to test the file you're having problems with. In this project the library doesn't appear to have any problems rendering your PDF -- I also tested version 7.12 and got the same successful result. Could you try this project on your end using the latest version to confirm the results? Latest version of the library can be downloaded from here: http://www.quickpdflibrary.com/products/quickpdf/updates.php Downoad RenderPageToVariant project uploads/1000/RenderPageToVariant.zip Cheers, - Rowan.

	Hi Ingo, Thanks for the advise, I've switched to 7.14 and the problem disappeared! :) Regards, Mick.

	Hi Rowan, Thanks a lot for the sample code, I made sure my code works in same manner as your, and installed version 7.14 - the problem disappeared! Regards, Mick.
