I would like to input an autosave feature in my C# program which will run a line of code at the end of the countdown, then restart the countdown. It will run my SaveFile(); function.
I would like this timer to be started when the user first saves/opens the document, and have it disabled if they open a new document.
You can use the Elapsed event on the System.Timers Timer.
Timer timer = new Timer(30 * 60 * 1000);
timer.Elapsed += OnTick; // Which can also be written as += new ElapsedEventHandler(OnTick);
private void OnTick(object source, ElapsedEventArgs e)
{
//Save logic
}
And don't forget to call timer.Start() when you need it.
You can also use DispatchTimer. Here's a snippet that plays one of five different videos every 5 minutes.
DispatcherTimer mediaTimer = new DispatcherTimer();
mediaTimer.Interval = TimeSpan.FromMinutes(5);
mediaTimer.Tick += new EventHandler(mediaTimer_Tick);
mediaTimer.Start();
void mediaTimer_Tick(object sender, EventArgs e)
{
nextMovie();
}
public void nextMovie()
{
if (mediaIndex >= 5)
mediaIndex = 0;
switch (mediaIndex)
{
case 0:
mediaElement1.Source = new Uri(videoFileName1, UriKind.Absolute);
break;
case 1:
mediaElement1.Source = new Uri(videoFileName2, UriKind.Absolute);
break;
case 2:
mediaElement1.Source = new Uri(videoFileName3, UriKind.Absolute);
break;
case 3:
mediaElement1.Source = new Uri(videoFileName4, UriKind.Absolute);
break;
case 4:
mediaElement1.Source = new Uri(videoFileName5, UriKind.Absolute);
break;
default:
mediaElement1.Source = new Uri(videoFileName1, UriKind.Absolute);
break;
}
mediaElement1.Visibility = System.Windows.Visibility.Visible;
mediaIndex++;
mediaElement1.Play();
}
You can use System.Timers.Timer. It also has Stop and Start methods so you can do whatever you want.
System.Timers.Timer myTimer = new Timer(30 * 60 * 1000);
myTimer.Start();
myTimer.Elapsed += new ElapsedEventHandler(myTimer_Elapsed);
void myTimer_Elapsed(object sender, ElapsedEventArgs e)
{
//your code
}

Check Length
LblLength.Text = TxtInput.Text.Length.ToString();
Make To Upper
LblUpper.Text = TxtInput.Text.ToUpper();
Make To Lower

LblRight.Text = TxtInput.Text.Substring(TxtInput.Text.Length - 3);
Show Middle Characters
LblSubscript.Text = TxtInput.Text.Substring(1, 3);
