AnglesAvailable Property

AnglesAvailable Property
This component is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems. It may be altered or unavailable in subsequent versions.
The AnglesAvailable property retrieves the number of angles currently available.
Syntax
[ iAngles = ] MSWebDVD.AnglesAvailable
Return Values
Returns an integer value from 1 through 9 representing the number of angles currently available. If iAngles = 1, there is no angle block at the current location.
Remarks
This property is read-only with no default value. An angle block is a video segment that was shot from more than one camera angle. There can be up to nine angles in an angle block, numbered from 1 through 9. When the DVD Navigator first enters an angle block, it sends your application an EC_DVD_ANGLES_AVAILABLE event notification with the number of angles in lParam1. A disc can be authored to automatically show a menu for available angles when it enters an angle block, but generally an application must determine the number of angles available and offer the user a way to select one.
