Return Value

Some documents such as PDF can be protected and cannot be read without the user supplying a password. The readers will automatically detect if a document is encrypted, and will call the DocumentReaderGetPasswordCallback delegate set in the DocumentReaderLoadOptions.GetPasswordCallback property. The application can then show a dialog box to prompt the user for the password (or set a fixed value if the password is known in advance).

For an example, refer to DocumentReaderLoadOptions.

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
