I am wrong!

Thank you for your reply!

 

What you have to do is ...
first the create ...
then LoadFromFile or similar ...
then check if the file is encrypted:
If ( QP.EncryptionStatus > 0 ) Then
   QP.Decrypt;
then the merge-syntax ...

then the save.

 

About encryption you can read here:
http://www.quickpdflibrary.com/help/quickpdf/DocumentProperties.php

About merge you can read here:
http://www.quickpdflibrary.com/help/quickpdf/DocumentManipulation.php

 

Samples in different development languages (packed as zip) are here:
http://www.quickpdflibrary.com/samples/index.php

 

In the developer-guide starting at page 28 you'll find a good merge-sample:
http://www.quickpdflibrary.com/docs/Quick%20PDF%20Library%207%20Developer%20Guide.pdf
It's a pascal-sample but for a developer it shouldn't be a problem to convert it to any other language.

Hi.

Can you see

this is what i do use itextsharp.dll to merge 3 encrypted pdf files to a pdf file.

when you double click ConsoleApplication1.exe, then it will create a PDFS.pdf that is merge from the  3 encrypted pdf files.

but i can't do it use QuickPDF.

How can do it use QuickPDF with vb6?

Thanks!

when use c#, below is the whole code:

whether i use ExtractFilePages or CapturePage or CopyPageRanges I can't merge the  3 encrypted pdf files to a pdf file as itextsharp.dll.

Can you help?

Thanks!

 

 

Many pdf-files are encrypted - so QuickPDF can do this job, too.

I don't know if it's a problem merging encrypted pdf-files but:

QuickPDF can load a pdf...

then you can check if it's encrypted...

if so you can decrypt it with an easy function call ;-)

 

Cheers and welcome here,

Ingo 

Use iTextSharp for .net can Merge encrypted Pdf files,

but use QuickPDF can't Merge encrypted Pdf files?

Thanks!
