Oh that explains why I can’t see any of it, I opened it in a vb.net project on an earlier version of Studio. I can at least see your high level logic. Awesome solution, I had wondered if the classification results could be updated like that. I have a project where the PDFs are very long and the digitize step takes too long. We aren’t doing automatic classification, we are presenting the user with Classification Station. But the digitize and classify steps are still required so I spoof the document DOM in a similar fashion by building it manually to avoid the digitize step.
