Net (gb.net)

This class provides constant definitions used by the rest of the classes in this component.

Most of them are linked with the Status property of Net classes. In that case:

• Error values are always negative values.

• An inactive value is always zero.

• Activity is reflected with positive values.

You can determine if there was an error, by checking whether the Status property is negative.

Constantes

Accepting	This constant shows that a remote client is trying to connect with a server socket, and that the connection is being accepted.
Active	This constant shows that a network object is working at this moment.
CannotAuthenticate	Const CannotAuthenticate As Integer = -16
CannotBindInterface	This error constant means that binding a ServerSocket to a specific interface failed.
CannotBindSocket	This constant reflects that a network socket was unable to use (bind) to a port.
CannotCreateSocket	This constant reflects that a network object was unable to create a new socket, the system did not allow the operation to be performed.
CannotListen	This constant reflects that a server socket was unable to start listening on a TCP port or a local path.
CannotRead	This constant reflects that there was an error when trying to read data from a socket or a serial port.
CannotWrite	This constant shows that there was an error when trying to write data to a socket or a serial port.
Connected	This constant reflects that a socket, acting like a client, is currently connected to a remote server.
Connecting	This constant reflects that a socket, acting like a client, is trying to connect to a remote server.
ConnectionRefused	This constant reflects that a remote server refused a connection from a client socket.
ConnectionTimeout	This constant means that there was a connection timeout.
HostNotFound	This constant reflects that an object from one of the Net classes failed to translate a host name to an IP address.
IPv4	Constant used by Format for IPv4 addresses.
Inactive	This constant reflects that a network object is doing nothing, it is inactive.
Internet	Defines an Internet domain socket.
Local	Defines a local or an Unix domain socket.
Pending	This constant reflects that a remote client is trying to connect with a server socket, and that connection must be accepted or rejected.
ReceivingData	This constant means that some data is being downloaded from the network.
Searching	Reflects that an object from one of the Net classes is trying to translate a host name to an IP address.
Unix	Defines a local or Unix domain socket.
