Sleeping without pausing the main thread

Expand Post »

Well im trying to "sleep" or make the program twiddle its thumbs for 15 seconds before continueing but without pausing the main thread.

So i thought maybe if i create a new thread and Sleep in that one that would help but no.

So then i thought the timer object but still no.

Now i dont know if the above "no"'s are because im completely stupid and cant use them or they didnt actually work.....

Heres the new thread method i stole from microsoft.

C# Syntax (Toggle Plain Text)
class Sleep
{
    static TimeSpan waitTime = new TimeSpan(0, 0, 15);
 
    public static void sSleep()
    {
        Thread newThread = new Thread(new ThreadStart(Sleeping));
        newThread.Start();
 
        if (newThread.Join(waitTime + waitTime))
        {
            //
        }
        else
        {
            //
        }
    }
    static void Sleeping()
    {
        Thread.Sleep(waitTime);
    }
}
class Sleep
{
    static TimeSpan waitTime = new TimeSpan(0, 0, 15);

    public static void sSleep()
    {
        Thread newThread = new Thread(new ThreadStart(Sleeping));
        newThread.Start();

        if (newThread.Join(waitTime + waitTime))
        {
            //
        }
        else
        {
            //
        }
    }
    static void Sleeping()
    {
        Thread.Sleep(waitTime);
    }
}

That didnt work for me (it paused the main thread)

If someone could show me how to use the timer correctly that would be much appriciated.

Re: Sleeping without pausing the main thread

I don't understand your problem. You're trying to make your program 'sleep' without pausing the main thread? That's not really a sleep because sleep would be a blocking call. If what you need is a timer, then use the Timer class. Here is how it looks in short:

C# Syntax (Toggle Plain Text)
 
Timer mTimer = new Timer(TIMEOUT_VALUE);
mTimer.Elapsed += new ElapsedEventHandler(TIMEOUT_METHOD);
mTimer.Start();
                
Timer mTimer = new Timer(TIMEOUT_VALUE);
mTimer.Elapsed += new ElapsedEventHandler(TIMEOUT_METHOD);
mTimer.Start();

Here is the signature for TIMEOUT_METHOD

C# Syntax (Toggle Plain Text)
 
public void MyMethod(object source, ElapsedEventArgs e)
{ }
            
public void MyMethod(object source, ElapsedEventArgs e)
{ }

This method will execute when your timer ends. The timer will then restart automatically when the call to this method completes.

Re: Sleeping without pausing the main thread

Timer is also a component on your toolbar - with other examples on how to use it in your helpfile.

Re: Sleeping without pausing the main thread

Perhaps if you let the main thread spawn a new thread. You could pause the new thread and let the main thread continue?
