Hi every body,
I've got a so strange issue I can't solve myself.
I've got a pdf file, containing 4 pages. When I open it with Acrobat reader or Foxit reader, there is no problem.
But when I try to do:
oPdf.SelectPage 4, an error appears, telling me that there is an error, with no explanation (error -2147418113 (8000ffff)).
Anybody can explain me what's wrong ?
Note that this error occurs only with few pdf files, every time on the last page...
Thanks in advance
Eddy

--------------------------
I've partially solved the problem. It appears that my pdf was not perfect. There was a conflict of font. However, what is strange is that I was able to open the pdf with a reader, without any error or warning message...

Hi Eddy,

first of all:

What version do you use?

With key or without?

The adobe reader installation is about 100 mb - and QuickPDF?

The adobe reader can manage faulty documents with a lot of dll-stuff instead of the smaller QuickPDF.

A repairing run through/with PDFTK can help before using QuickPDF.

Try something similar to this one:

         QP := TiSEDQuickPDF.Create;
         try
            QP.UnlockKey('mypersonalkey');
            QP.LoadFromFile(fneu);
            If ( QP.Encrypted > 0 ) Then
               QP.Unencrypt;
            x    := QP.PageCount;
            For i := 1 to x Do
                begin
                   QP.SelectPage(i);

// and so on ...

Best regards and welcome here,

Ingo

Thank you for your response, Ingo, I will try what you propose, to unencrypt before selecting the page.

Indeed, I have not been precise enough in my question.

I work in VB6, with quickpdf version 5.22.0.119 (dll version number).

I don't understand the question With key or not ? Do you mean the unlockkey ? If yes, I have one.

I will give you more details after testing Ingo's proposition...

Bye and thank you again.

Hello again,
Well, I've tried your proposition, Ingo, but the pdf document in error is not encrypted, so, there is no change at all.
However, I've noticed that the "wrong" pdf files contain a font (ARIAL), which size is 367112 !!! I don't know how the pdf is generated : it cames from OpenOffice or Ms office, I suppose. Is it possible to modify or delete an embbeded font ?
Thank you in advance for your reponses.

I can also open the documentwith my version of quickpdf. The problem is I can not do a SelectPage on the last page of the document. Could you verify that point ?
Do you know when the new version will be available ?

Hi Eddy,

i've tested it with your doc.pdf this moment and it works. Page 16 could be selected. You can make a clear preview (RenderDocumentToFile) from each page and you can initiate textextraction from each page. The current (still not published) version won't have any problems with your document.

I think it's still a matter of weeks publishing the new version.

Best regards,

Ingo

I'm using the latest version of QuickPdf and I've got the same issue:

In fact, on a 1 page doc, SelectPage(0) works but SelectPage(1) doesn't.

Looks like page count is a 0 based counter...
