Access the nodes of scene.nodes using JsObject COM/OLE

Hi,

I am trying to open a collection of PDF files and execute script in each annotation 3D found in each PDF.

I have created a program that does the trick using addScript but I have encountered issues I can't resolve regarding Security when a PDF is secured and addScript fails. Using jsObject, I am getting the scene of the 3D annotation and I am able to access scene.nodes.

But I can't figure how to reach each node by its index. I have tried to do (C#) :

Type javascriptObjectType = a_javascriptObject.GetType();

return javascriptObjectType.InvokeMember("getByIndex", BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance, null, a_javascriptObject, new object[]{ 0 });


where a_javascriptObject is my COM object of the result of scene.nodes. I am able to access the property count of scene.nodes though.

Is it possible to get a node by its index? What am I doing wrong?
