The Start method begins listening for client
connections on the specified local address and port number. The
server is started in its own thread and manages the client sessions
independently of the calling thread. All arguments are optional. If
a given argument is missing, then a corresponding property or
properties must be set before attempting the connection, as
follows:
LocalAddress specifies the IP address of the network
adapter that the control should use when listening for connection
requests. If this is an empty string or the special address
"0.0.0.0" is specified, the server will listen for connection on
all valid network interfaces configured for the local system. If
this argument is not specified, the control will accept connections
on the address specified by the value of the
ServerAddress property.
LocalPort specified the port number to listen for
connections on. If this argument is not provided, it defaults to
the value specified by the ServerPort
property.
Backlog specifies the maximum size of the queue used to
manage pending connections to the service. If the argument is set
to value which exceeds the maximum size for the underlying service
provider, it will be silently adjusted to the nearest legal value.
On Windows workstations, the maximum backlog value is 5. On Windows
servers, the maximum value is 200. If this argument is not
provided, the value specified by the Backlog property will
be used.
MaxClients specifies the maximum number of clients that
may connect to the server. If this argument is not provided, the
value specified by the MaxClients property will be
used. A value of zero specifies that there is no fixed limit to the
number of active client connections that may be established with
the server. This value can be adjusted after the server has been
created by calling the Throttle method.
Timeout specifies the number of seconds the control
will wait for a network operation to complete. A value of zero
indicates that the control should wait indefinitely for the
operation to complete, however it is not recommended that you use
this value. If this argument is not specified, the value of the
Timeout property will be used as the default.
Options specifies one or more socket options which are
to be used when establishing the connection. The value is created
by combining the options using a bitwise Or operator. Note that if
this argument is specified, it will override any property values
that are related to that option.

Description |
| 2 |
swOptionDontRoute |
This option specifies default
routing should not be used. This option should not be specified
unless absolutely necessary. |
| 4 |
swOptionKeepAlive |
This option specifies that packets
are to be sent to the remote system when no data is being exchanged
to keep the connection active. This is the same as setting the
KeepAlive property to a value of True. |
| 8 |
swOptionReuseAddress |
This option specifies that the
local address can be reused when the server is stopped and
immediately restarted. This is the same as setting the
ReuseAddress property to a value of True. |
| 16 |
swOptionNoDelay |
This option disables the Nagle
algorithm, which buffers unacknowledged data and insures that a
full-size packet can be sent to the remote host. This is the same
as setting the NoDelay property to a value of
True. |
| &H1000 |
swOptionSecure |
This option specifies that the
server will enable the security protocols and negotiate with the
client to establish an encrypted session. This is the same as setting the Secure property
to a value of True, and requires that a Secure Edition
license. |
