hi guys,
i have a problem please, i want to run a timer with 20 milliseconds interval but a method (methodA) calls it and start it. it is needed that timer should complete its task after 10 execution ( means that the total time will be 200 millisecond for a task).

i want that methodA should wait for the 10 execution of the timer please.

any idea please, or what could be the best proper solution.

thanks

Why not set the timer for 200ms??

Muhammad Tufail 1979 4-Jul-14 11:42am

cause 200ms are for the whole task. the task is to move an object (i.e picture) from one place to another place in the panel within 10 interval and thus the time will be for each move should be 20ms.

I hope you don't want an accurate 20ms, because the timer is unlikely to give you that.

could you please explain me a bit more. Actually i want to keep the time constant (i.e 20ms) for each iteration, so thus the moving of picture will be smooth.

Okay so what is the specific question here? Can you not implement a timer? Set a timer interval? Count to 10? Implement an autoresetevent?

yes please, i can implement timer, and to set its interval time 20 ms and a counter which should count for it up to 10. but i don't know how methodA ( which is the caller or the starter of this timer) should wait until timer completes 10 execution of 20ms.

What do you mean you don't know how? You have already been told this. http://www.codeproject.com/Questions/787004/how-to-synchronize-nested-thread-with-its-parent-o?arn=0

Why? It sounds more like using a separate thread explicitly...

sorry , Sergey Alexandrovich , could you please explain a bit more.

Timers have inherent problems; in many cases using a thread is much better and straightforward. If you explain your ultimate goal, I'll try to illustrate this simple idea using your case.

Easy! Create a class level counter, set it to the number of iterations, and count it down in the Tick event:

C#

    Timer myTimer = new Timer();
    myTimer.Interval = 20;
    myTimer.Tick += new EventHandler(myTimer_Tick);
    intervalCounter = 10;
    myTimer.Start();
    }
private int intervalCounter;

void myTimer_Tick(object sender, EventArgs e)
    {
    if (intervalCounter > 0)
        {
        intervalCounter--;
        if (intervalCounter == 0)
            {
            // Do what you want
            intervalCounter = 10;
            }
        }
    }
