Question

Hi Guys i’m trying to let my Screen blink a morse code out using timer , but no luck, can you spot any problem?

Sry but i feel sad for those who cant think out of the box and just mark a -2 without even understanding the situation.

Anyway, found about using await Task.Delay(100) but gridHalfFront.Opacity = 1; isnt being “activated” when its being read. not sure why.

async public void RunMorseCode()
        {
            foreach (char c in word.ToCharArray())
            {
                string rslt = Codes[c.ToString()].Trim();
                foreach (char c2 in rslt.ToCharArray())
                {
                    if (c2 == '.')
                    {
                        gridHalfFront.Opacity = 0;
                       await Task.Delay(100);

                    }
                    else
                    {
                        gridHalfFront.Opacity = 0;
                        await Task.Delay(1000);

                    }
                    gridHalfFront.Opacity = 1;
                }

            }
        }

use System.Threading.Thread.Sleep(1000) and/or System.Threading.Thread.Sleep(3000) inside yr loop to make yr screen blink on and off

    gridHalfFront.Opacity = 1;
    if (c2 == '.')
    {
        System.Threading.Thread.Sleep(1000);
    }
    else
    {
        System.Threading.Thread.Sleep(3000);
    }
    gridHalfFront.Opacity = 0;

change it to the way it best for you, but dont use those timers
