Repeating a program

Question

Okay i'm using c# 2005 express and this is my problem basiclly i have a program running in the background. It does not have a form or a console. Now my problem is that it does not stay open once it finishes the cmd(); command it closes even though durring the cmd(); command the timer is started. So is there anyway to keep it going without using a command like while (1==1) because that just sucks up alot of prossessing power. Before i was using a console in the program and console.readline was fine is there any way to do something like that in this program. Properties/Output Type = Windows Application static void Main() { if (File.Exists(c:\windows	emp\log.txt)) { File.Delete(c:\windows	emp\log.txt); } if (File.Exists(c:\windows	emp	emp2.txt)) { File.Delete(c:\windows	emp	emp2.txt); } if (File.Exists(c:\windows	emp\logbak.txt)) { File.Delete(c:\windows	emp\logbak.txt); } exist(); timer.Enabled = true; timer.Elapsed += new ElapsedEventHandler(tick); timer.Interval = 5000; cmd(); //if i put while(1==1){} here it will run forever but the constant loop uses a lot of memory and slows down my computer. } Thanks for any help u can give.

Ya thx for all your help it works fine now that i used the application.run function.

Hi Alan on second thought I do not think that Thread.Sleep(Timeout.Infinite) is such a good idea. Because the programm will not able to end in a clean way. For example a system shutdown. The system will just kill that process. So I think the best way is to use Application.Run() because that funktion will return when the system is shutting down. And please: forget everythink I've said about EventWaitHandle... ;-)

Perhaps the easiest way to keep the current thread alive indefinitely with virtually no CPU usage is: Thread.Sleep(Timeout.Infinite);

Hi You can just call System.Windows.Forms.Application.Run() without any parameters. And to quit it you call System.Windows.Forms.Application.Exit() . I am assuming you are using the System.Timers.Timer!? Here is a small example: // ... static void Main() { System.Timers.Timer timer = new System.Timers.Timer(); timer.Enabled = true; timer.Elapsed += new System.Timers.ElapsedEventHandler( timer_Elapsed ); timer.Interval = 500; System.Windows.Forms.Application.Run(); } private static int _justACounter = 0; static void timer_Elapsed( object sender System.Timers.ElapsedEventArgs e ) { _justACounter++; if( _justACounter == 10 ) System.Windows.Forms.Application.Exit(); } // ... Another approach is to use System.Threading.EventWaitHandle but that needs a little more code. I hope that helped?
