118 Chapter 6: Using the Built-In Classes
Media classes
The media classes provide playback control of sound and video in a SWF file, as well as access to
the user’s microphone and camera, if they are installed. These classes are located in the Built-In
Classes > Media subfolder in the Actions toolbox.
Client-server classes
The following table lists classes that let you send and receive data from external sources or
communicate with application servers over FTP, HTTP, or HTTPS.
Note: In Flash Player 7, a SWF file can load data only from exactly the same domain from which it
was served. For more information, see “Flash Player security features” on page 188 and “About
allowing cross-domain data loading” on page 190.
