Connect(String,Int32) Method

Connect to a host.

[Visual Basic]
<DescriptionAttribute("Connect to a server.")>
Overloads Public Sub Connect( _
   ByVal server As String, _
   ByVal serverPort As Integer _
)

[C#]
[DescriptionAttribute("Connect to a server.")]
public void Connect( 
   string server,
   int serverPort
);

[C++]
[DescriptionAttribute("Connect to a server.")]
public: void Connect( 
   string* server,
   int serverPort
)

[C++/CLI]
[DescriptionAttribute("Connect to a server.")]
public:
void Connect( 
   String^ server,
   int serverPort
)

Parameters

server: Remote hostname or address in dot notation.
serverPort: Remote port, a number between 1 and 65535, inclusive.

Remarks

The Connect method establishes a network connection between the default local network interface/port and the device identified by remote network address/port. If no exception is thrown, the connection has succeeded and the Connected property will return true after this method returns. Once the connection has been made, you can send/receive data to/from the server.

This method always blocks until the attempted connection succeeds or fails.

Example

The following example demonstrates blocking operations using the Tcp component.

[Visual Basic]

Private Sub TcpDemo()

   ' The following code assumes that good responses are always received from

   ' the server. More robust code should check each response and handle appropriately.



   ' Connect to Echo Server

   Tcp1.Connect("myEchoServer", 7)



   ' Send some data

   Tcp1.Send("Hello Server!" + vbCrLf)



   ' Get response from the server

   Dim seg As Segment = Tcp1.Receive()

   Debug.WriteLine(seg.ToString())



   ' Send more data

   Tcp1.Send("You are a swell host" + vbCrLf)



   ' Get response from the server

   seg = Tcp1.Receive()

   Debug.WriteLine(seg.ToString())



   'Close the connection

   Tcp1.Close()

End Sub

[C#]

private void TcpDemo()

{

  // The following code assumes that good responses are always received from

  // the server. More robust code should check each response and handle appropriately.



  // Connect to Echo Server

  tcp1.Connect("myEchoServer", 7);



  // Send some data

  tcp1.Send("Hello Server!\r\n");



  // Get response from the server

  Segment seg = tcp1.Receive();

  Debug.WriteLine(seg.ToString());



  // Send more data

  tcp1.Send("You are a swell host\r\n");



  // Get response from the server

  seg = tcp1.Receive();

  Debug.WriteLine(seg.ToString());

  

  //Close the connection

  tcp1.Close();
