I am doing the first steps with Mono and C #, and I stalled on a stupid
problem.
I implemented a timer that launches an event every X seconds.
Now when the procedure is called I want to change a label but I can not
because I receive this message
"` MainWindow.label2 ': An object reference is required for the nonstatic
field "
How can I fix?
// MainWindow.cs created with MonoDevelop
// User: franaria at 11:21 15/05/2008

Headers

using System;
using System.Diagnostics;
using System.IO.Ports;
using System.Net;
using System.Net.Sockets;
using System.Threading;
using System.Timers; //per la gestione dei timer
using Gtk;
using Modbus.Device;
public partial class MainWindow: Gtk.Window
{
private static System.Timers.Timer ourTimer;
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
Build ();
ourTimer = new System.Timers.Timer();
// attach to the Elapsed event.
ourTimer.Elapsed += new ElapsedEventHandler(OnTimerElapsed);
// make our timer interval 1 second
ourTimer.Interval = 1000;
//Build ();
}
protected void OnDeleteEvent (object sender, DeleteEventArgs a)
{
Application.Quit ();
a.RetVal = true;
}
protected virtual void Butt1Start (object sender, System.EventArgs e)
{
}
protected virtual void OnButton2Clicked (object sender,
System.EventArgs e)
{
if (ourTimer.Enabled == false)
{
ourTimer.Enabled = true ;
button2.Label = "Starting read";
}else
{
ourTimer.Enabled = false ;
button2.Label = "Start Timed read";
}
}
private static void OnTimerElapsed(object sender, ElapsedEventArgs e)
{
Console.WriteLine("Timer elapsed at: " +
e.SignalTime.ToLongTimeString());
//label2.Text = "Timer elapsed at: " +
e.SignalTime.ToLongTimeString();
<--- Problem
//button2.Label = "Running Timed Read";
<---
}
}
Thanks to all :blush:
