Read-Write-Sign an XPS Document Sample
The XpsReadWriteSign sample shows how to read, write, and digitally sign an XML Paper Specification (XPS) document. When the program starts a "File" menu with "New..." and "Open..." options are displayed. Selecting "File | New..." opens a "New XPS Document" dialog allowing you to specify the name of the new XPS document that you wish to create and write; predefined content is provided and used to create the new XPS document. Selecting "File | Open..." displays an "Open" dialog allowing you to choose an existing XPS document to open (a sample XPS document, ViewFixedDocumentSequence.xps, is provided). Once an XPS document has been created or opened, the document is displayed in the DocumentViewer control hosted within the main application window. With an XPS document open, the "File | Signatures..." option is enabled allowing you to view existing signatures of individuals who have signed the document, and to add additional signatures of your own. To sign an XPS document, your system must have an X.509 certificate manager installed such as for use with a SmartCard (the program will display an error message and exit if a certificate manager is not installed and running).
This sample demonstrates a specific feature of the Windows Presentation Foundation (WPF) and, consequently, does not follow application development best practices.
