ConnectDescTemplate

Summary

Contains the

ConnectDescTemplate

object associated with the

specified

MessageTag

object. This template contains

parameters used when creating connections

.

Setting the ConnectDescTemplate property with a modified

ConnectDescTemplate object will cause the attributes of a

connection to be updated, if the message tag the property

belongs to is the hub for that connection.
If the message tag is not yet added to a connection, it is

assumed that you will call the Connect method to create the

connection immediately after setting this property. If you do

not, reading the ConnectDescTemplate property will return

the old (default) ConnectDescTemplate object.
To modify the attributes of an existing connection

description, modify its ConnectDescTemplate properties as if

it were a new object. Setting the ConnectDescTemplate

property with a modified ConnectDescTemplate object will

cause the attributes of a connection to be updated, if the

message tag the ConnectDescTemplate object belongs to is the

hub for that connection.
