My window has onstart method as:
protected override void OnStart(string[] args)
{
// Interval in milliseconds
string myInterval = System.Configuration.ConfigurationManager.AppSettings["ServiceInterval"].ToString();
double interval = Convert.ToDouble(myInterval);
// Create timer object
MyTimer = new System.Timers.Timer(interval);
MyTimer = new System.Timers.Timer();
// Set to run more than once
MyTimer.AutoReset = true;
MyTimer.Enabled = true;
// Delegate to handle the timer event
MyTimer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
// Start the timer
MyTimer.Start();
// Prevents garbage collection from occuring in long running methods
GC.KeepAlive(MyTimer);
// TODO: Add code here to start your service.
//code for date check
eventLog1.WriteEntry("ExactService started");
}
I want to Have my OnStart method kick off a background thread where a separate class is instantiated that has the methods i want for my business logic.
how to do this.
I am doing so coz the window service is not working properly :
