Hi Gerald!

This is from the iSED-Knowledgebase. You can find it here at www.quickpdf.org on the starting page, too.
It's not in a specific language.

Best regards,

First, you must load in the two documents you want to merge, and store the ID of each document for later use:

QP.LoadFromFile("file1.pdf")
Doc1 = QP.SelectedDocument
QP.LoadFromFile("file2.pdf")
Doc2 = QP.SelectedDocument

Now you simply select the first document, and request that the second document be merged to the end of it:

QP.SelectDocument(Doc1)
QP.MergeDocument(Doc2)

At this point the second document will have been automatically removed, but the first document (with the second document merged to the end) is still selected. It's a simple matter to save the merged document:

QP.SaveToFile("merged.pdf")
QP.RemoveDocument(Doc1)

If you need to quickly merge more than 2 documents, consider using the QP.MergeFileListFast method.

Ido,

In my experience MergeFileList and MergeFileListFast do not work properly. I have been using QuickPDF for about 3 years now in both ASP and VB environments.

I have attempted to use MergeFileList and MergeFileListFast to merge 2 or more PDFs together without success. I am on v5.11 Active/X library. The merged files count returned from the calls always returns 0, no matter how many files I have in my FileList.

Is there a way to get more specific error information as to why the merge fails?

These methods all work, but I have had some problems when the files get very big and have many form fields.

Merging in memory has worked fine for several years until we added a lot of fillable fields. We recently switched to the MergeFileListFast() method which is working better.

You need to make sure you have temp paths set up and write access for the IIS user.

QP.SetTempPath("d:/temp")
QP.SetTempFile("d:/temp/pdftemp.dat")

MergeFileListFast() is returning the count merged files.

I am using QuickPDF 5.11/AX in a VB 6.0 application and trying to merge 3 PDF files that are about 400KB each, so write access for the IIS user is not an issue. Setting TempPath and TempFile have no effect.
