Offset Property

The offset into the buffer.

[Visual Basic]
Public ReadOnly Property Offset As Integer

[C#]
public int Offset {get;}

[C++]
public: __property int get_Offset();

[C++/CLI]
public:
property int Offset {
   int get();
}

Return Type

An integer representing the offset into the buffer.

Remarks

Use this property to access offset parameter of the Receive and Send methods.

When using the Tcp component, using Tcp.Send or Tcp.Receive will return a Segment object. The buffer offset is available through Segment.Offset.

When using the Udp component, using Udp.Send or Udp.Receive will return a Datagram object. The buffer offset is available through Datagram.Offset.

Use this property to properly access the data available in Segment.Buffer or Datagram.Buffer.

When using other PowerTCP components, a Segment or Datagram object (which one depends on if TCP or UDP is used as the transport protocol) is made available to describe data sent or received, often in a Trace event. The Segment.Offset or Datagram.Offset property contains the offset into the buffer.

Example

The following example demonstrates connecting to a server while specifying a local interface to use.

[Visual Basic]

' Connect to the server, specifying the local interface to use

Tcp1.Connect("atropos", 13, "192.168.0.83", 8888)



' Since connection was to DAYTIME port (13), simply receive the time

Dim seg As Segment = Tcp1.Receive()



Debug.WriteLine("Time reported by server: " + seg.ToString())

[C#]



// Connect to the server, specifying the local interface to use
tcp1.Connect("atropos", 13, "192.168.0.83", 8888);


// Since connection was to DAYTIME port (13), simply receive the time
Segment seg =
tcp1.Receive();



Debug.WriteLine("Time reported by server: " + seg.ToString());
