How can I open a password protected PDF, extract a specific portion of it and have the extract portion display in a picture box? My main issue is with opening the password protected PDF.

Keitha,

Sometimes, a PDF document is encrypted using a password which doesn't allow you to load it directly. To overcome this issue, simply check whether the PDF file is encrypted or not using the Leadtools.Documents.Document.IsEncrypted property:
https://www.leadtools.com/help/leadtools/v19/dh/dox/leadtools.documents~leadtools.documents.document~isencrypted.html

If the property is True, you can supply the password to decrypt the PDF file using Leadtools.Documents.Document.Decrypt() method:
https://www.leadtools.com/help/leadtools/v19/dh/dox/leadtools.documents~leadtools.documents.document~decrypt.html

You can also refer to the following help topic for more details:
