Quick PDF with Visual Studio 2017 C#

Hi
I'm trying to get Quick PDF working on a website built in Visual Studio 2017 with C#.   I've been following the instructions but they seem to be for a different version than the one I bought.   After installation trying to reference any of the DLLs from VS like
C:\Program Files (x86)\Quick PDF Library\DLL\QuickPDF64DLL0814.dll
C:\Program Files (x86)\Quick PDF Library\DLL\QuickPDFDLL0814.dll
Gives the error "The reference is invalid or unsupported"
I can reference the Interop in
C:\Program Files (x86)\Quick PDF Library\Demo\Interop.QuickPDFAX0814.dll
though, but while the line
QuickPDFAX0814.PDFLibrary objQuickPDF = new QuickPDFAX0814.PDFLibrary();
compiles, when I try running the webpage the following error is shown
"FileNotFoundException: Could not load file or assembly 'Interop.QuickPDFAX0814, Version=8.14.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified"

The line, according to the instructions for the different version, should be
QuickPDFAX0814.PDFLibrary objQuickPDF = new QuickPDFAX0814.PDFLibrary("C:\\Program Files (x86)\\Quick PDF Library\\DLL\\QuickPDFDLL0814.dll");
but that breaks with the error
"'PDFLibraryClass' does not contain a constructor that takes 1 arguments"

Either way, I get access to the methods within QuickPDF e.g.
objQuickPDF.UnlockKey(strTheKey);

How do I get the project to recognise the reference and/or get the webpage to run without either error message appearing?
Thanks

Hi Glyn,

all informations about the different versions of the library should be here:
http://www.debenu.com/products/development/debenu-pdf-library/
On that page on the right side are Getting started guides for each version - this will help... i'm pretty sure ;-)

Cheers and welcome here,
Ingo

I kinda figured I'd have to put the correct filename in with the correct version and not just any random bit of text from the internet and kinda figured people would realise that I'd at have to know that at bare minimum so they could see I was using the DLL of QuickPDFAX0814 by all the times I typed it in and know which version I was using.

I've went through the guides, demos and samples before I asked the question. It seemed a bit rude to not even attempt to follow the documentation before asking for help. The developer guide points to some code samples at
http://www.quickpdflibrary.com/samples/download/csharp_dll_sample.zip
seems the most relevant, but when I download it it says
Source file 'C:\quickpdfdemo\DebenuPDFLibraryDLL1011.cs' could not be found
Which is because it's not there in the zip.   All of the other samples have the same problem.   And none of that is for QuickPDF, though I'm guessing you just change the file name which is what I did in the first place.

Following on from there, in the Quick PDF Library 8 Developer Guide, the "Getting started DLL edition" link
http://www.quickpdflibrary.com/help/getting-started-dll.php
which links from the documentation, that's all for DebenuPDFLibraryDLL1011 and I can't find any mention of DPL or Debenu in any of the code, DLLs, etc. I've got after installation and none of the references match

And the demo code from
http://www.quickpdflibrary.com/tutorials/csharp/hello-world.php
doesn't work either

DebenuPDFLibraryDLL1011.cs will be in the library package.
This has nothing to do with the sample files in the ZIP.
If somebody asking for C:\quickpdfdemo\DebenuPDFLibraryDLL1011.cs then anywhere this path is hard coded inside. Find it and change it to your needs.
