automatically. The session establishment time for a profile can be configured

using the xDriver Profile Editor. For more information, see xDriver Profiles on

page 134.

BeginIncomingSessionEvents

Applies to: Object Server object

This method is used to register for incoming session event handling. The

application is then notified of incoming uplink session requests to the LNS

Server.

Syntax

objServer.BeginIncomingSessionEvents xDriverProfileName

Table 38. BeginIncomingSessionEvents Parameters

Element Description

xDriverProfileName xDriver profile name as a String (20 characters max). The application

is informed of incoming session requests that come in on the TCP

listener port assigned to the specified profile. You can use the

OpenLDV xDriver Profile Editor to enable a profile for incoming

session handling and assign it a listener port. For more information,

see xDriver Profiles on page 134.

Remarks

This method can be invoked multiple times per application if you want to use

multiple profiles to listen for incoming session requests in a single application.

However, multiple applications cannot register for uplink session event handling

with the same profile simultaneously.

After an application has registered for incoming session handling with this

method, the OnIncomingSessionEvent event is fired each time a request for

connection is received. The application is then responsible for accepting or

rejecting all incoming uplink sessions. For more information on this event, see

OnIncomingSessionEvent on page 157.

EndIncomingSessionEvents

Applies to: Object Server object

This method is used to end uplink session event handling within an application.

It must be called before closing an application that has registered for uplink

session handling with the BeginIncomingSessionEvents Method, or when the

application should no longer be responsible for handling incoming sessions.
