Repeating a program

Cutch

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\\temp\\log.txt")) { File.Delete("c:\\windows\\temp\\log.txt"); }

if (File.Exists("c:\\windows\\temp\\temp2.txt")) { File.Delete("c:\\windows\\temp\\temp2.txt"); }

if (File.Exists("c:\\windows\\temp\\logbak.txt")) { File.Delete("c:\\windows\\temp\\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?
