In addition, the Network Name drop-down box will list all networks
accessible by your application as soon as you select a client type. For
source code information, see
CDlgInitializeGeneral::SelectClientType in the
dlginitializegeneral.cpp file. The client type is passed into
m_iClientType. The description of the monitor and control example
later in this appendix provides more details on each of the client types
you can select.
2. From the Interface Name drop-down box, select a network interface.
This drop-down box lists all configured L ON W ORKS network interfaces
available on your system (i.e. all the network interfaces included in the
NetworkInterfaces collection). For initialization source code information,
see CDlgInitializeGeneral::InitNetworkInterfaceName() in the
dlginitializegeneral.cpp file.
3. From the Network Name drop-down box, select an already existing
network from the drop-down list or create a new network by typing in the
name of the new network. Although this lists all networks known to the
LNS Object Server (i.e. the Network collection), you should note that the
network management example can only manage networks created with
the example application. For source code information, see
LcaHelper::GetNetworks(void). For selection and initialization
steps see CDlgInitializationGeneral::InitDatabaseName() from
the dlginitializegeneral.cpp file.
4. Once you have selected a client type, a network interface and a network,
you need to specify the licensing mode, as described in Chapter 4 of this
document. To select the licensing mode, select the License tab on the
dialog shown in Figure C.1. You will then be able to select either
Standard Mode or Demonstration Mode. If you select Standard Mode, you
will need to enter the customer ID and customer key.
5. Click Set Now to save your changes. This will reinitialize the LNS Object
Server, if necessary. For source code information on this, see
OpenObjectServer in the LcaHelper.cpp file.
6. Now, select the General tab to return to the dialog shown in Figure C.1.
If you selected a new network in step 3, click the Create button (or the
Add button if you are running as a Lightweight client). This creates an
example network if you are running as a LNS Full client using the
Networks collection, or adds an entry to the global database if you are
running as a Lightweight client.
For Local clients, or Full clients using the RemoteNetworks collection, a
"template network" is created called __LNS320TEMPLATE that will be
used as a basis for all future networks. This network is created in the
<LNSDIR>\lm\db\lns32 folder, where <LNSDIR> represents the target
directory you have chosen to install LNS to. The template network
contains device and connection description templates. To generate an
example network, a backup of this "template network" is created and
then imported with the network name you had specified. The network is
first opened with the system management mode set to
lcaMgmtModeDeferConfigUpdates to prevent the propagation of
