# vapidemo

The `vapidemo` sample program is a Windows application that demonstrates most of the functionality of the Viewing API. To start the `vapidemo` program, double-click the `vapidemo.exe` file, or type `vapidemo` at a DOS prompt or in the Run dialog box.

NOTE: Menu options in `vapidemo` do not adjust according to the format of the document you view; however, they appear shaded if they do not apply to the format. This is a limitation of the sample program only, not the Viewing SDK.
