I want to be able to open PDF files and read the contents for order processing using Visual Studio 2017 & C#.
But I can't make sense of the documentation
I see parts like this
How can I extract text from PDF documents using the Acrobat DC SDK?
You can extract text with the Acrobat DC SDK in two ways:
Use the Acrobat core API
Use the Acrobat automation API
How can I use Visual Basic .NET or Visual C# .NET with the Acrobat DC SDK?
The Windows version of Acrobat is an OLE automation server. In order to use the OLE objects made available by Acrobat, you must have the full Acrobat product installed on your system and the Acrobat.tlb file included in the project references for your Visual Basic project. This allows you to use the Visual Studio 2005 object browser to browse the OLE objects.
It should be easy to add more code to improve and extend the capability.
- The way to set up using Acrobat IAC in the project is from the menu
Project -> Add Rerences... -> COM to select Acrobat.
but I don't know where to get it, or what I have to buy, and i'm hoping that it is just an old documentation that it is referencing a 14 year old version of VS.
The core API is strictly for plugins written in C++.
