Opening the Object Server
Once you have set the network access mode, and licensing mode for your Lightweight
client application, you can open the Object Server, as shown below:
ObjectServer.Open()
NOTE: If you will be opening any networks with an LNS application that is running as a
Windows service, then the first application to open the LNS Object Server must also be
running as a Windows service. In addition, if a network is to be opened by an LNS
application that is running as Windows service, then that network and system must be
opened by an LNS application that is running as Windows service before it is opened
with an LNS application running as a user process. For more information on this, consult
the help pages for the Open() methods of the Network and ObjectServer objects in
the LNS Object Server Reference help file.
Opening a Network
This section describes how to connect to a network with a Lightweight client application.
Lightweight client applications cannot create new networks. The LNS Server utility
must be running on the PC containing the LNS databases (i.e. the LNS Server PC) to
open a network with a Lightweight client application. To connect to an existing network
with a Lightweight client application, follow these steps:
1. Retrieve the Networks collection from the ObjectServer object’s
Networks property. The Networks collection will contain all Lightweight
client networks that have been entered into the Windows Registry on the
PC running your application (i.e. all the networks that have previously
been opened on your PC).
Dim MyNetworks as LcaNetworks
