Hi

I built a windows service program which needs to keep on checking data in mssql db for every minute.

In Modules.Systems.UpdateProcess, there have another 2 functions need to connect to different tables in the same DB.

If I set timer2, timer3 and interval = 360000, will they be crashed? as all 3 objects connect to DB in the same time.  

Modules.Systems.UpdateProcess UP = new Modules.Systems.UpdateProcess();
            this.timer1 = new System.Timers.Timer();
            this.timer1.Interval = 360000; 
            this.timer1.Elapsed += new ElapsedEventHandler(UP.UpdateBalance);

I don't see a problem with this. It should connect and query the database fine.

This is because SQL server can handle multiple connection from the same application or from multiple applications

Yes, I set different connection, but the problem is the code in 2nd and 3rd timers did not execute.
private System.ComponentModel.IContainer components = null;
 
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
 
        private void InitializeComponent()
        {
            components = new System.ComponentModel.Container();
            this.eventLog1 = new System.Diagnostics.EventLog();
            ((System.ComponentModel.ISupportInitialize)(this.eventLog1)).BeginInit();
            Modules.Systems.Process UP1 = new Modules.Systems.Process();
            Modules.Systems.Process UP2 = new Modules.Systems.Process();
            Modules.Systems.Process UP3 = new Modules.Systems.Process();
 
            this.eventLog1.Log = "Log";
            this.eventLog1.Source = "LogSource";
            this.timer1 = new System.Timers.Timer();
            this.timer1.Interval = 360000; 
            this.timer1.Elapsed += new ElapsedEventHandler(UP1.UpdateClientABalance);
            this.timer2 = new System.Timers.Timer();
            this.timer2.Interval = 360000; 
            this.timer2.Elapsed += new ElapsedEventHandler(UP2.UpdateClientBBalance);
            this.timer3 = new System.Timers.Timer();
            this.timer3.Interval = 360000;
            this.timer3.Elapsed += new ElapsedEventHandler(UP3.UpdateClientCBalance);
 
            ((System.ComponentModel.ISupportInitialize)(this.eventLog1)).EndInit();
            this.ServiceName = "Processing";
 
        }
 
        private System.Timers.Timer timer1;
        private System.Timers.Timer timer2;
        private System.Timers.Timer timer3;
        private System.Diagnostics.EventLog eventLog1;

Insert the following statements near the end of the InitializeComponent() routine (but before the (System.ComponentModel.ISupportInitialize ...) statement):
this.timer1.start();
this.timer2.start();
this.timer3.start();
