I created a simple C#
app that uses the beep console. I want to add a stop button to stop the beeping, but once the app starts to run it doesnt let me hit a close/button button. Below is the code i have.
private void button1_Click(object sender, EventArgs e)
{
int int1, int2, hours;
int1 = int.Parse(txtbox1.Text);
int2 = int.Parse(txtbox2.Text);
hours = ((60 / int1) * int2);
for (int i = 0; i <= hours; i++)
{
Console.Beep();
Thread.Sleep(int1 * 60000);
}
}
The reason is that you execute button1_Click
in the GUI thread. When you call this method the thread will be stuck there for quite some time because you make it sleep.
If you remove Thread.Sleep(int1*60000);
you will notice that your application is unresponsive until it is done beeping.
You should try to use a Timer
instead. Something like this should work (this is based on the Windows.Forms.Timer
):
private Timer timer = new Timer();
And set it up
timer.Tick += OnTick;
timer.Interval = int1 * 60000;
...
private void OnTick(object o, EventArgs e)
{
Console.Beep();
}
In your buttonclick you are now able to start and stop the timer:
timer.Start();
or
timer.Stop();
I would use a timer in this case, the reason why you can't close the form is because you are calling a sleep on the form thread from what I understand. Calling a sleep on the form thread will give the impression the app has crashed.
Here is a quick sample code I built in c#, it will beep the console at the time given. I hope it helps.
private void button1_Click(object sender, EventArgs e)
{
timer1.Tick += new EventHandler(timer_dosomething);
timer1.Interval = 60000;
timer1.Enabled = true;
timer1.Start();
}
private void button2_Click(object sender, EventArgs e)
{
timer1.Stop();
}
void timer_dosomething(object sender, EventArgs e)
{
Console.Beep();
}
