    Hi how can i make a windows form button work for on and off ? So when I click it the first time it turns my speech synthesis on and the next time i click it turns it off ? This is what i have tried but it doesn't work :(

    private void button1_Click(object sender, EventArgs e)
        {
            SpeechSynthesizer SS = new SpeechSynthesizer();
            bool onOff = true;

            if (onOff == true)
            {
                SS.Speak(forReading.Text);
            }
            else if (onOff == false)
            {
                SS.Dispose();
            }
            
        }

    forReading.Text is my textbox to read from.

    I thought maybe using a bool(onOff) may be the way but I have no experience so im only guessing

    Hi,

    move the bool onOff outside the methods body, to make it a class level variable to make it keep the value you set:

    bool onOff = true;

private void button1_Click(object sender, EventArgs e)
        {
            SpeechSynthesizer SS = new SpeechSynthesizer();
            
            if (onOff == true)
            {
                SS.Speak(forReading.Text);
            }
            else if (onOff == false)
            {
                SS.Dispose();
            }
            
           //maybe set/reset onOff here too
        }

    Regards,
