Open a PDF file from a WinJS Application

Question

I've got an application in which the user clicks a button, and should be presented a PDF that is stored in the application.

They can view the PDF internally in the app, or launch the native windows PDF viewer, either way is fine.

How can I provide a link / event handler for the button click to launch a view of a PDF file?

Answer 1

Use the LaunchFileAsync function of the Launcher class,

description: Starts the default app associated with the specified file, using the specified options.

example code:

Windows.System.Launcher.launchFileAsync(file, options).done( /* Your success and error handlers */ );
