IFileViewer
The IFileViewer interface designates an interface that allows a registered file viewer to be notified when it must show or print a file.
When to Implement
You implement this interface to provide a means for your registered file types to be viewed and/or printed.
When to Use
You do not normally use this interface. The shell calls the interface when the user chooses the Quick View command from a file's context menu and the file is a type that the file viewer recognizes.
IFileViewer Methods Description PrintTo Prints a file. Show Displays a file. ShowInitialize Prepares to display a file.
