Hello
I am having a problem in simulating a queue that have one server
I need to make a queue of circles that arrive according to an arrival rate
then the circles will move one a time to the server for a service time and disappear I don't know how to do this
Can any one help even by giving hints
I started by making multiple circles using a for loop, but how can I use the timer for each circle to move according to the arrival rate
and how to make the circles stop at the server??

Thanks

Remember that we don't know what you talk about, we don't see your screen, we can't read your mind.
reread the question, if you understand because you have a knowledge that is not written down on the question, you need to refine the question.
A queue of circle means nothing to us.

Voted #1: This is not a solution, but a question for the user, and should be a comment.

Hi Bill,
I don't like the 1, but I am happy of the message, At least I can understand the reason of 1.
More like an advice than a question, I would say.
Do you have knowledge about 'queue of circles' ?

Solution 1

.NET offers a pre-made FIFO queue... Queue Class (System.Collections)[^]

If I define a new queue
Queue q = new Queue();
q.Enqueue(??);
Do I need to define a class called circle and pass it as an object
How can I enter circle to the queue ??

Kornfeld Eliyahu Peter 10-Apr-18 2:16am

Yes. You should have a class that representing your circle and than you can use Queue to store it...
public class Circle {};
Circle oCirc = new Circle();
Queue<circle> oQueue = new Queue<circle>();
oQueue.Enqueue(oCircle);

I have a question about the timer shall I need a timer to move each circle or one timer for all cause when I try to move with timer all the circles move??

Kornfeld Eliyahu Peter 10-Apr-18 11:10am

Why timer - two separate processes/threads...
One - to receive incoming circles and push them on the queue
Two - to pull out circles one-by-one...

private void Form1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
for (int i = 0; i <= 5; i++)
{
ellipse = new MyEllipce(wid, y);
ellipses.Enqueue(ellipse);
ellipse.Draw(g, wid, y);
wid += 20;
}

I made this code in a for loop because I have a number of customer, but how to make each circle appear after a specific arrival time
and how to dequeue from the queue each time I use dequeue it move a circle to a position, but don't remove it from the queue
