Returns the VirtualRoot object as specified by the Index value.
Syntax
NSUnicastMgr.VirtualRoots.Item( Index )
Parameters
Index
The index value is defined as a variant type. It can be expressed in the following ways.
| Syntax | Type | Definition |
| Item( 0 ) | Integer | Position of the element in the collection. |
| Item( “0” ) | String | Position of the element in the collection. |
| Item( 0.0 ) | Real | Position of the element in the collection. |
| Item( “Alias” ) | String | The alias name of the virtual root. |
String values are assumed to be the alias name or directory path, unless the search for a corresponding virtual root fails. Then the system attempts to convert the string to a number, and search for the virtual root by its position in the collection.
Remarks
Item is the default property for this object, and it need not be specified explicitly. Note the two equivalent forms of syntax in the following example.
Example
' Display alias of the first root
MsgBox (NSUnicastMgr.VirtualRoots.Item[0].AliasName)
' Display port ID of the last client
MsgBox (NSUnicastMgr.VirtualRoots[NSUnicastMgr.Count – 1].AliasName)
