Hi all,

when executing the following code in Delphi XE2 I get an access violation:

    AktPDF := PDFLibrary.SelectedDocument; //default 1-page Doc
    if not PDFLibrary.LoadFromFile(ExtractFilePath(Application.ExeName)+'\Org.pdf','') = 1 then halt(0);
    orgPDF := PDFLibrary.SelectedDocument;
    PDFLibrary.SelectDocument(aktPDF);
    PDFLibrary.CopyPageRanges(orgPDF,'1'); // -> access violation when copying first page of loadad pdf

I'm really stuck at the moment

Can anyone give me a hint where my problem is?

Thanks

Wolfgang

Hi Wolfgang!

What's before the line with "AktPDF"?
Is there an additional LoadFromFile?
If not that's the prob.

Cheers and welcome here,
Ingo

Hello Ingo,

no the AktPDF should point to the initial Document when creating the QPDFLib.

The error also occurs if I change the fist line to

AktPDF := PDFLibrary.NewDocument;

Regards

you should check the value in "AktPDF".

Hello Ingo,

AktPDF and orgPDF both seem to be a valid DocID.
orgPDF is one digit hiher than AktPDF, so this seems to be OK for me.

The PDF file is most likely maformed or corrupted. Acrobat often repairs many documents which are corrupted and so it is not always easy to see if a document is corrupt or not.

You may need to send the PDF's to the official support pages and we can check the file.

As the PDF is a confidential document, how can I send the file to you?

If you create a support case using the link - http://www.quickpdflibrary.com/support/support-query.php - http://www.quickpdflibrary.com/support/support-query.php then you will be given a case number. If you then reply to that email you can attach the file and it will only be accessible by the support staff at Debenu and will be treated as confiential.
