Question

PDF Reader control (Windows, C#) - How to get current page number?

I built a six-panel PDF display app, with 6 instances of the PDF Reader COM control on a Windows Form, and everything works great.

When the program loads, it reads a settings file to open the last set of PDF files so the user can continue where he left off.

I use SetCurrentPage so the user can specify what page to start each PDF on. But when the app exits, I need to SAVE the new current page so the user doesn't have to do this manually.

In order to restore the last page in each PDF, I have to find out the current page of the PDF Reader controls.

The control exposes a .setCurrentPage method, but nothing to GET the current page number. The exposed methods and properties don't seem to provide any access to the current page number.

Is there a way to do this?

Two DLL's are resident in the project: AxInterop.AcroPDFLib.dll and Interop.AcroPDFLib.dll, if that's relevant.

Thanks in advance,

Allen

Get the AVPageView from the AVDoc, then use AVPageView.GetPage();

Thanks, Thom,

Is this a COM object? I'm not sure how to include it in the VS IDE for C#.

Also, will there be an instance of AVPageView in every instance of the Reader control?

BTW, this is for internal noncommercial use (and I have a full CC license).

I've taken a look at the AVPageView online docs, but I haven't yet seen how to incorporate it into my project.

Yes it is a COM object,or rather a COM interface. I may have been mistaken to have suggested it. This part of the AcroExch API is only available through Acrobat Professional. It's not in Reader 😞

Please see the reference for clarification:

There is no method in the control for this.

Ouch. That's a major disappointment. Do you have any suggestions for a slightly more useful way to instantiate a PDF reader inside a Win desktop C# app?

Thanks.
