When attempting to upload one or more PDF's that is missing a title, author, or subject; an unhandled exception is being thrown after the PDF's are copied into the top level of the Upload folder. Normally, when a PDF is missing a title, author, or subject; PDFKeeper is supposed to move the PDF to the UploadRejected folder. Unfortunately, because PDFKeeper has crashed, the PDF's will remain in the Upload folder causing the same unhandled exception to be thrown when PDFKeeper attempts to upload again after restarting.

Both PDFKeeper v9.0.0 and v9.1.0 are impacted by this bug.

The stack trace of exception that is logged to PDFKeeper.log
System.NullReferenceException: Object reference not set to an instance of an object.
at PDFKeeper.Core.Rules.PdfMetadataRule.CheckForViolation()
at PDFKeeper.Core.FileIO.PDF.PdfUploader.StagePdfFilesInUploadDirectory()

at PDFKeeper.Presentation.MainView.VB$StateMachine_491_UploadTimer_Tick.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

To prevent PDFKeeper from crashing again after restarting; move the PDF's out of C:\Users\your_username\AppData\Roaming\Robert F. Frasca\PDFKeeper\Upload and then restart PDFKeeper.

I am evaluating your software to see if it will work for a repository of PDF documents that were created by a CAD program. Although I'm evaluating it on my personal computer, the intended end use is on a computer with no internet access whatsoever. To that end, I've tried downloading and then running the SingleUserDatabaseSetup windows command script, which fails with "the system cannot find the file specified".

I figure this is the SqliteDatabaseSetup.sql file. Is that correct? Is it possible to get a local copy of this file?

Perhaps a larger (and more pertinent) question would be: Can this software be used on such an isolated system?

Thanks for your attention!

An issue was discovered in PDFKeeper 9.0.0 when uploading PDF documents that contains one or more image pages. The issue is that text extraction is not being performed when the page is an image. The cause has been identified and the fix is being tested that will be included in PDFKeeper 9.1.0.

To work around the issue:

When adding a PDF to the database that contains one or more image pages, select the following in the Add PDF dialog:

When editing an Upload Profile that will be used for uploading PDF documents to the database that contains one or more image pages, select the same option in the Upload Profile Editor.
