private void button1_Click(object sender, EventArgs e) { //Add variable to agent agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace"); agent1.Variables.Values.Add(agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace")); //Start listening for requests agent1.Start(agent1_MessageReceived, null); } private void agent1_MessageReceived(Agent agent, RequestMessage request, object state) { //Create and send a response whenever a request is received agent1.Send(agent1.CreateDefaultResponse(request), request.Origin); } | |
| Visual Basic | Copy Code |
|---|---|
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click 'Add variable to agent agent1.Variables.Values.Add(agent1.Mib.CreateVariable(NodeName.sysContact, "Kara Thrace")) 'Start listening for requests agent1.Start(agent1_MessageReceived, Nothing) End Sub Private Sub agent1_MessageReceived(ByVal agent As Agent, ByVal request As RequestMessage, ByVal state As Object) 'Create and send a response whenever a request is received agent1.Send(agent1.CreateDefaultResponse(request), request.Origin) End Sub | |
Remarks
This method provides a convenient means for receiving SNMP request messages on a worker thread, and should be used to receive and respond to SNMP requests.
The state parameter can be null when no state information is passed to the worker delegate function.
Unhandled exceptions occurring on the worker thread are caught and reported in the ComponentBase.Error event.
