hello,
I am using HiveMQ broker to publish and subscribe. so I created wpf application to get the message it working fine.
and same thing I tried with ASP.net But it not working. while debugging I am able to get the data but not displaying it on form.
Is there any other way to do this on web application or am I missing some thing? Plz give some idea.
note:
and i m using
this.Dispatcher.Invoke(() =>
what is the alternative for same behaviour in asp.net.
private MqttClient mqttClient;
public MainWindow()
{
InitializeComponent();
mqttClient = new MqttClient(IPAddress.Parse(txtConnectionString.Text).ToString());
mqttClient.MqttMsgPublishReceived += client_MqttMsgPublishReceived;//event
mqttClient.MqttMsgSubscribed += client_MqttMsgSubscribed;//event
}
private void client_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)
{
this.Dispatcher.Invoke(() =>
{
lstSubscribe.Items.Add("Recevied..." + System.Text.Encoding.UTF8.GetString(e.Message));
});
}
private void client_MqttMsgSubscribed(object sender, MqttMsgSubscribedEventArgs e)
{
this.Dispatcher.Invoke(() =>
{
lstSubscribe.Items.Add("Topic " + txtTopic.Text);
lstSubscribe.Items.Add("Subscribed for id " + e.MessageId);
lstSubscribe.Items.Add(" ");
});
}
private void btnConnect_Click(object sender, RoutedEventArgs e)
{
try
{
mqttClient.Connect(Guid.NewGuid().ToString());
lstPublish.Items.Add("*** Connected");
}
catch (Exception ex)
{
lblError.Content = ex.Message.ToString();
}
}
private void btnSubscribe_Click(object sender, RoutedEventArgs e)
{
mqttClient.Subscribe(new string[] { txtTopic.Text }, new byte[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });
}
