Example

The following example demonstrates sending an inform message.

C#	Copy Code
private void button1_Click(object sender, EventArgs e) { //Send an Inform request on a worker thread manager1.Start(sendInformRequest, null); } private void sendInformRequest(ManagerSlave slave, object state) { //Create an inform message and send it to a manager InformMessage inform = new InformMessage(); inform.Version = SnmpVersion.Two; //The inform includes this manager's uptime inform.Variables.Add(manager1.Mib.CreateVariable(NodeName.sysUpTime, manager1.AuthoritativeEngine.Time.ToString())); slave.GetResponse(inform, myManagerAddress, 162); }

Copy Code

private void button1_Click(object sender, EventArgs e)
{
  //Send an Inform request on a worker thread
  manager1.Start(sendInformRequest, null);
}

private void sendInformRequest(ManagerSlave slave, object state)
{
  //Create an inform message and send it to a manager
  InformMessage inform = new InformMessage();
  inform.Version = SnmpVersion.Two;

  //The inform includes this manager's uptime
  inform.Variables.Add(manager1.Mib.CreateVariable(NodeName.sysUpTime, manager1.AuthoritativeEngine.Time.ToString()));
  slave.GetResponse(inform, myManagerAddress, 162);
}

Visual Basic	Copy Code
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click 'Send an Inform request on a worker thread manager1.Start(AddressOf sendInformRequest, Nothing) End Sub Private Sub sendInformRequest(ByVal slave As ManagerSlave, ByVal state As Object) 'Create an inform message and send it to a manager Dim inform As InformMessage = New InformMessage() inform.Version = SnmpVersion.Two 'The inform includes this manager's uptime inform.Variables.Add(manager1.Mib.CreateVariable(NodeName.sysUpTime, manager1.AuthoritativeEngine.Time.ToString())) slave.GetResponse(inform, myManagerAddress, 162) End Sub

Visual Basic

Copy Code

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click
  'Send an Inform request on a worker thread
  manager1.Start(AddressOf sendInformRequest, Nothing)
End Sub

Private Sub sendInformRequest(ByVal slave As ManagerSlave, ByVal state As Object)
  'Create an inform message and send it to a manager
  Dim inform As InformMessage = New InformMessage()
  inform.Version = SnmpVersion.Two

  'The inform includes this manager's uptime
  inform.Variables.Add(manager1.Mib.CreateVariable(NodeName.sysUpTime, manager1.AuthoritativeEngine.Time.ToString()))
  slave.GetResponse(inform, myManagerAddress, 162)
End Sub

Remarks

This message is used to send variables from one manager to another. A ResponseMessage containing the same variables is used to acknowledge the receipt of the information.
