It would be very good if in addition to merging, the power to split and digitally sign the PDFs.

It would be nice if could use C# for the DLL so that could make use of SnapDevelop + PB to complete the project.
Thank you.

I just downloaded the files - I extracted the pdfutilsdemo.zip to c:\pdfutilsdemo - i opened the workspace and it says the following targets could not be opened c:\pdfutildemo\concatpdf.pbt - i have given full access to all users on the folder and its not read only

Any ideas on what to try please

as always thanks in advance

Hello Bruce,
I'd like to try this interesting funcionality but I found a problem in Tool -->'.NET DLL Importer' from PB IDE.

I opened your 'concatpdf' demo app and I tried to re-import PDF2Util2.dll file but returns an error (see attachment): "It's impossible to load file or assembly 'netstandar,verion=2.1.0.0,Culture=neutral,PublicKetToken=ccb13.....' or relative dependency".

maybe some dll files are missing or what else?

fine!
regards

Hello Bruce,

I get this error when I try to run the pdfsharp version of this. Do you why I get this error?

Thanks

Hi Bruce,
So excited you made this utility as we are using a RTE control to merge a bunch of data-records into some RTF templates and want to save them as PDFs. I'm new to using RTE controls, and as far as I can tell, The RTE SaveDocument() method only saves a single "instance" of the document, so I'd need to loop through the data rows and save each document as a separate PDF file. We want to deliver the results as a single PDF file, so I'd need to merge them all back together.

I'm trying out your PODOFO sample app, and it works, but only if the PDF files I choose are in the same folder as the PDFUtils.dll (or maybe the executable folder). If they are elsewhere, the app crashes. I tried putting the DLL (and all the others you included in the zip file) in a folder in my computer's PATH (although pretty far down the list), and I also tried using the full path of where I put the DLL in the external function declaration...

FUNCTION int merge ( string input1, string input2, string output ) LIBRARY "c:\code\test\PDFUtils.dll"

But those didn't work. Is there something else I need to do?

I'll try the SharpPDF approach next, but it had some problems with it loading the system.text.encoding.dll on initial test.

Hi Bruce,
we have a bunch of pdf file to merge.
Is it possible to pass to 'merge function' all files into string array to make merge all at once?
I tried to modify the pdfutil2 c# source code and reimport the dll but doesn't work, the call at 'merge function' returns code error = 3.

these are my changes at the source (unfortunately I still don't know c# language):
namespace PDFUtil2
{
public class PDFUtils2
{
public int merge(string[] inpFileName, string outFileName)
{

Encoding.RegisterProvider(CodePagesEncodingProvider.Instance);

PdfDocument outputDocument = new PdfDocument();

foreach (string fileName in inpFileName)
{
PdfDocument inputDocument = PdfReader.Open(fileName, PdfDocumentOpenMode.Import);
for (int idx = 0; idx < inputDocument.PageCount; idx++)
{
PdfPage page = inputDocument.Pages[idx];
outputDocument.AddPage(page);
}
}
outputDocument.Save(outFileName);
return 1;
}
}
}
Thanks

There are users who have standard user privileges on their workstation and the pdfsplitmerge.dll we use fails to register when the PowerServer app starts. We have had their admin manually register the dll at the cmd prompt. Each time the user runs the Web Client app, a Registration Error message appears saying this dll failed to register even when it was manually registered. The big problem is not being able to use this dll to merge the multiple documents. The users are insurance agents and they have the ability to select multiple documents to generate. We use this library to combine the various pdf files into 1 pdf file for convenience.

Thank you Bruce for your code! My company has used it in PB 2021 Build 1288 successfully. We upgraded our application to PB 2021 Build 1311 and the PDF merge works when we run the app within the PB IDE. When the application is deployed to a client/server environment, the same code crashes the application. Do you know if there are new libraries to deploy using PB 2021 1311? We deploy this app to PowerServer 2021 using the PB 2021 1311 and the PDF merging functionality works fine. That's why I wonder if there is a new or different library to include with the client/server version of the app that was missed in our client/server test. Thanks again for this solution!
