Creating Components Dynamically

When using Visual Studio .NET, the Agent and Manager components can also be added as a reference. In this case there are a few extra steps you must take, namely:

You must instantiate your own event handlers.
You must create and add a licenses.licx file to the project.

Use the following steps to add the Agent and Manager components as a reference within Visual Studio .NET:

Start Visual Studio .NET.
From the File menu, choose New, then choose Project.
From the resulting dialog box, choose either Visual C# Projects or Visual Basic Projects then choose Windows Application. Specify a name and a location for the project, then click OK.
Now add the Agent or Manager component as a reference. To do this right-click the References folder in the Solution Explorer and choose Add Reference. If the Solution Explorer is not visible, navigate to the View menu and choose Solution Explorer.

The following dialog will appear.

Select Dart.PowerSNMP.dll and click OK.
Now you must add a licenses.licx file to the project. (See the topic "Creating A Licenses.licx File" for more information).

Now make a quick application to test. Drag a button onto the form and insert the following code:

[C#]
using Dart.PowerSNMP;

private void button1_Click(object sender, System.EventArgs e)
{
        Manager manager1 = new Manager();
        // Create a GetRequest message
        GetMessage req = new GetMessage();
        // Add an intrinsic MibObject (to get the system description)
        req.Variables.Add(new Variable(new Dart.PowerSNMP.MibObject.sysDescr()));
        // Send a broadcast request to default port 161 and collect all responses
        ResponseMessage[] responses = manager1.GetResponses(req);
        foreach (ResponseMessage response in responses)
                // Add the system description into listBox1
                listBox1.Items.Add(response.Variables[0].Value);
}

Navigate to the Debug menu and choose Start. The application will compile and execute. Click the button and you should see a list of network agents in the listbox.
Note: This example shows usage without events. For most applications you will have to create your own event handlers. To do this, see the "Using Events" topic.
