❔ What did I do wrong with this task formation?

I want to make an infinite method that generates a random number for a "slot machine". I also have to be able to stop it upon click of a button to finalize a number.
The vital code is this:

        public async Task Numbers(TextBox textbox, CancellationToken token)
        {
            Random rnd = new Random();
            while (token.IsCancellationRequested == false)
            {
                textbox.Text = rnd.Next(1, 10).ToString();
                await Task.Delay(100);
            }
        }

        public async void Check(TextBox textbox, Button button)
        {
            CancellationTokenSource cts = new CancellationTokenSource();
            if (button.Text == "Launch")
            {
                Task.Run(() => Numbers(textbox, cts.Token), cts.Token);
                button.Text = "Stop";
            }
            else if (button.Text == "Stop")
            {
                cts.Cancel();
                button.Text = "Launch";
            }
        }

        public async Task Numbers(TextBox textbox, CancellationToken token)
        {
            Random rnd = new Random();
            while (token.IsCancellationRequested == false)
            {
                textbox.Text = rnd.Next(1, 10).ToString();
                await Task.Delay(100);
            }
        }

        public async void Check(TextBox textbox, Button button)
        {
            CancellationTokenSource cts = new CancellationTokenSource();
            if (button.Text == "Launch")
            {
                Task.Run(() => Numbers(textbox, cts.Token), cts.Token);
                button.Text = "Stop";
            }
            else if (button.Text == "Stop")
            {
                cts.Cancel();
                button.Text = "Launch";
            }
        }

        public async Task Numbers(TextBox textbox, CancellationToken token)
        {
            Random rnd = new Random();
            while (token.IsCancellationRequested == false)
            {
                textbox.Text = rnd.Next(1, 10).ToString();
                await Task.Delay(100);
            }
        }

        public async void Check(TextBox textbox, Button button)
        {
            CancellationTokenSource cts = new CancellationTokenSource();
            if (button.Text == "Launch")
            {
                Task.Run(() => Numbers(textbox, cts.Token), cts.Token);
                button.Text = "Stop";
            }
            else if (button.Text == "Stop")
            {
                cts.Cancel();
                button.Text = "Launch";
            }
        }

        public async Task Numbers(TextBox textbox, CancellationToken token)
        {
            Random rnd = new Random();
            while (token.IsCancellationRequested == false)
            {
                textbox.Text = rnd.Next(1, 10).ToString();
                await Task.Delay(100);
            }
        }

        public async void Check(TextBox textbox, Button button)
        {
            CancellationTokenSource cts = new CancellationTokenSource();
            if (button.Text == "Launch")
            {
                Task.Run(() => Numbers(textbox, cts.Token), cts.Token);
                button.Text = "Stop";
            }
            else if (button.Text == "Stop")
            {
                cts.Cancel();
                button.Text = "Launch";
            }
        }

the function Numbers() doesnt work when a part of task. if i put it as is it works.

valera456OP•6/19/23, 3:29 PM

what am i supposed to do then

valera456OP•6/19/23, 3:32 PM

i repurposed it to

       CancellationTokenSource cts1 = new CancellationTokenSource();
        CancellationTokenSource cts2 = new CancellationTokenSource();
        CancellationTokenSource cts3 = new CancellationTokenSource();
        public async Task Numbers(TextBox textbox, CancellationToken token)
        {
            Random rnd = new Random();
            while (token.IsCancellationRequested==false)
            {
                textbox.Text = rnd.Next(1, 10).ToString();
                await Task.Delay(100);
            }
        }
        public async void Check(TextBox textbox, Button button, CancellationTokenSource cts)
        {
            if (button.Text=="Пуск")
            {
                var task = Task.Run(()=>Numbers(textbox, cts.Token),cts.Token);
                button.Text = "Стоп";   
            }
            else if (button.Text=="Стоп")
            {
                cts.Cancel();
                button.Text = "Пуск"; 
            }
            if (button1.Text=="Пуск" && button2.Text == "Пуск" && button3.Text == "Пуск")
            {
                textBox1.Text = Determine(textBox2, textBox3, textBox4);
            }
        }
        public Form1()
        {

It still does not display any numbers on initial press.

valera456OP•6/19/23, 3:37 PM

i dont know? lemme see

valera456OP•6/19/23, 3:39 PM

i did

if (task.Status==TaskStatus.Running)
                {
                    MessageBox.Show("Yes");
                }

if (task.Status==TaskStatus.Running)
                {
                    MessageBox.Show("Yes");
                }

valera456OP•6/19/23, 3:40 PM

its not showing anything so its not running

valera456OP•6/19/23, 3:40 PM

but when i try to do task.Start() it says that its running on promise-style

valera456OP•6/19/23, 3:41 PM

so when does it run?

Original message was deleted

valera456OP•6/19/23, 3:43 PM

what do i check for exactly? in the locals or?

valera456OP•6/19/23, 3:45 PM

yes it does stop at the breakpoint. and it does get deeper into the actual number set of a textbox.

valera456OP•6/19/23, 3:46 PM

the application does not reflect that for some reason

valera456OP•6/19/23, 3:47 PM

by that i mean that no numbers are showing (they are showing if i call numbers() without the task)

valera456OP•6/19/23, 3:53 PM

so i have to out an int for that?

valera456OP•6/19/23, 4:06 PM

its now working correctly! thanks

Was this issue resolved? If so, run

/close

/close

otherwise I will mark this as stale and this post will be archived until there is new activity.
