To customize the text message pops on opening a secure PDF

Is there a way to change the text that pops up once I have protected a file with a password.

When I protected a file named “Protected.pdf”, and opened the file in windows, it comes up with the message:

"‘Protected.pdf’ is protected. Please enter a Document Open Password".

Can this be customized?


Hi Mike,

Thanks for your inquiry. I am afraid it is not possible to change the PDF viewer defined messages using Aspose.Pdf API. As it is class library and does nothing with GUI/Viewer, the notification messages are not a feature / property of PDF document but the features of the Tool / Viewer that is used to display the PDF document. Aspose.Pdf can only manipulate the PDF document and not the PDF Viewer /Tools.

Moreover, in order to control PDF viewer messages, you may consider using ViewerApp of our sister company named GroupDocs. They can help you to customize the notification messages in the application.

We are sorry for the inconvenience.

Best Regards,
