Related to this post, lets say I get the approval from Adobe (RIKLA stuff), will these classes work for Reader plugin?

i.e AcroAppClass and CAcroPDDoc

If not, what are the Reader plugin APIs available in SDK that does text extraction and highlight functionality in Reader (which is my only 2 requirement now).

What I was trying is to get hold of ActiveDoc once I pass on the control from Plugin code to my C# code, so that I can extract text and do the highlight stuff with the help of AcroAppClass  and CAcroPDDoc.

Ok. PDWordFinder will solve one of my problem as it will work for Reader. Now I can extract text from a Reader document and send it to my C# Form from plugin.

Now, from that Windows Form code, how can I highlight a particular word back in the PDF document. Is there a Reader supported API (#HiliteEntry?)

Thats great,atleast I have a way to talk back to Reader document from C#.

Can you please point me some SDK sample code which does this handshake? Meaning, invoking the plugin method from outside plugin code (in my case from C# Winform to plugin code to highlite a word).

Thanks!

But if there is a sample which atleast invokes a plugin method from outside, that will really help me to proceed further.

Or any direction of this sort will also helpful.

Replying to my own questions above....found a DDE (very old IAC technique and not usually recommended tough ) way to talk to Acrobat/Reader instance (called as DDE Server). There is a sample project which demonstrates DDE and it is in C++.

As I need to talk from my Winform, I am gonna use Ndde (open source) to talk back to Acrobat/Reader instance.

It would be more helpful if some sample code/project is available in SDK to demonstrate IAC via COM/OLE as DDE is a very old technique.

Irosenth, this is kinda contradicting. I remember you were saying "If Adobe approves your Reader plugin, then it can do what ever". Meaning COM/OLE/Named pipes. I thought COM/OLE is available for Reader, but your above reply says it strictly supports only DDE (which is gud for me as I hav explained above, am using DDE to send messages back to Reader instance to invoke the Highlite plugin function ).

Please can you clarify why COM/OLE is not available for Reader and why only old technique, DDE is available for Reader?

Thats convincing to me and good to know that Reader will support IAC via COM apart from DDE. I will try to create a COM component and expose the Highlite API, add reference to my C# Winform and invoke it from there.

Sid - What I had achieved using Ndde (opensource) is to make a connection from .Net code (Winform) to C++ code (Adobe Plugin). All my code does is to invoke C++ code from .Net to retrieve (read only) the contents/text of a PDF document and I did not do any EDITING.

What are you trying to achieve?
