error creating timer_elapsed handler.

[hazz]

Why do I get this error for this simple console app. It is complaining about
the 'timer1_Elapsed ' argument in
System.Timers.E lapsedEventHand ler(timer1_Elap sed);

An object reference is required for the nonstatic field, method, or property
'TestTimerInter valFromConfig.C lass1.timer1_El apsed(object,
System.Timers.E lapsedEventArgs )'
using System;
using System.Configur ation;
using System.Windows. Forms;
using System.Timers;
namespace TestTimerInterv alFromConfig
{
class Class1
{
public System.Timers.T imer timer1;
[STAThread]
static void Main(string[] args)
{
System.Timers.T imer timer1 = new System.Timers.T imer();
timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(timer1_Elap sed);
double interval =
Convert.ToDoubl e(System.Config uration.Configu rationSettings. AppSettings["interval"]);
timer1.Interval = interval;
timer1.Enabled = true;
}
private void timer1_Elapsed( object sender,
System.Timers.E lapsedEventArgs e)
{
MessageBox.Show ("Refresh the queue with a new view !");
}
}
}

Thanks, -Greg

hazz,
Since your Main method is static, so too must be your timer1 object and the
timer1_Elapsed handler. In a static method there is no class instance
object, so you need to make your other class objects and methods static too.

If you had created a separate class and were using an instance of the class,
that would be different.

Thank you Peter. That makes sense. I'm experimenting. -Greg

Thanks Peter. I got the configurable timer interval service to work !
I moved all the code to the onstart and made the timer and interval
static at the class level
Relevant code is below.
Thanks again. -Greg

public class Service1 : System.ServiceP rocess.ServiceB ase
{
static public System.Timers.T imer timer1;
static double interval;
***code **
protected override void OnStart(string[] args)
{
try
{
System.Timers.T imer timer1 = new System.Timers.T imer();
timer1.Elapsed += new
System.Timers.E lapsedEventHand ler(timer1_Elap sed);
interval =
Convert.ToDoubl e(System.Config uration.Configu rationSettings. AppSettings["interval"]);
timer1.Interval = interval;
timer1.Enabled = true;
}
catch(Exception ex)
{
MessageBox.Show ("In OnStart Component" + ex.ToString());
}
