Echelon LNS DDE Server - Manual (Page 35)

DDE Server Settings
Application Name
This setting specifies the DDE Application Name of the LNS DDE Server. This is not
the filename on disk of the server. It is the name that DDE client applications need
to use in order to be able to access the LNS DDE Server. The default setting is
“LNSDDE”.
If this item is changed, the server will need to be stopped and restarted in order for
the change to have an effect. A series of dialogs will help you through the restart
process.
Register DDE Share Name
By default, the LNS DDE Server creates a DDE share name specifically for itself. In
some instances, this has caused conflicts with applications that set up application-
specific shares. This option allows you to turn off the generation of DDE Share
names by the LNS DDE Server.
NetDDE Being Used
This setting influences how quickly the LNS DDE Server responds back to a DDE
client when the client initially requests a value. Under normal circumstances the
server may wait up to a minute before it responds back to a client that it is unable to
deliver a valid value. When this option is checked, the server will report back
immediately, usually with a timeout.
This option is provided for applications to allow them to bypass network delays when
operating over a network using the NetDDE protocol. Although the server will
initially report a timeout, the server will subsequently report an actual value when
available, and most clients will handle this update correctly.
This option should be selected for DDE client applications using the DDEML API.
The DDEML API requires immediate notification when setting up an advise,
otherwise the DDEML API may disconnect the conversation if it takes more than 60
seconds for the LNS DDE Server to retrieve the point value. When this option is
selected, the LNS DDE Server will send the client an immediate notification for each
advise request made.
This setting should not be enabled for most networks, even when a client operates
over a network using NetDDE.
See Using NetDDE in the LNS DDE Server Help File for more information.
