I am using below code to display time left in hh:mm:ss format for example if duration is 30min, it will show like this 00:30:00 and after 1 min it will show 00:29:00, how can i also display the remaining seconds and decrease them accordingly.,
Edit
I tried timer1.Interval = 1000; and
examTime = examTime.Subtract(TimeSpan.FromSeconds(1));
But its not showing me seconds reducing each second, How do i do it ?
public SubjectExamStart()
{
InitializeComponent();
examTime = TimeSpan.FromMinutes(double.Parse(conf[1]));
label1.Text = examTime.ToString();
timer1.Interval = 60 * 1000;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (sender == timer1)
{
if (examTime.TotalMinutes > 0)
{
examTime = examTime.Subtract(TimeSpan.FromMinutes(1));
label1.Text = examTime.ToString();
}
else
{
timer1.Stop();
MessageBox.Show("Exam Time is Finished");
}
}
}
Instead of Subtracting TimeSpan.FromMinutes you need to subtract from TimeSpan.FromSeconds
public SubjectExamStart()
{
InitializeComponent();
examTime = TimeSpan.FromSeconds(double.Parse(conf[1]));
label1.Text = examTime.ToString();
timer1.Interval = 1000;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (sender == timer1)
{
if (examTime.TotalMinutes > 0)
{
examTime = examTime.Subtract(TimeSpan.FromSeconds(1));
label1.Text = examTime.ToString();
}
else
{
timer1.Stop();
MessageBox.Show("Exam Time is Finished");
}
}
}
If you want to format the Time Span value while assigning to Label... You can use below..
label1.Text = examTime.ToString(#"dd\.hh\:mm\:ss");
To do this properly, you will need to keep a track of when the timer was started
DateTime examStartTime;
System.Windows.Forms.Timer runTimer;
TimeSpan totalExamTime = new TimeSpan(1, 30, 0); // Set exam time to 1 hour 30 minutes.
if (runTimer == null)
runTimer = new System.Windows.Forms.Timer();
runTimer.Interval = 200;
runTimer.Tick -= new EventHandler(runTimerTick);
runTimer.Tick += new EventHandler(runTimerTick);
examStartTime = DateTime.Now;
runTimer.Start();
Then in the event handler you can do:
public void runTimerTick(object sender, EventArgs e)
{
TimeSpan currentExamTime = DateTime.Now - examStartTime;
if (currentExamTime > totalExamTime)
{
MessageBox.Show("Exam Time is Finished");
runTimer.Stop();
runTimer.Tick -= new EventHandler(runTimerTick);
runTimer.Dispose();
}
}
I hope this helps.
try this hope this will work for u
set timer interval=1000
minremain=1200000; //Should be in milisecond
timerplurg.satrt();
private void timerplurg_Tick(object sender, EventArgs e)
{
minremain = minremain - 1000; //substring One second from total time
string Sec = string.Empty;
if (minremain <= 0)
{
lblpurgingTimer.Text = "";
timerplurg.Stop();
return;
}
else
{
var timeSpan = TimeSpan.FromMilliseconds(Convert.ToDouble(minremain));
var seconds = timeSpan.Seconds;
if (seconds.ToString().Length.Equals(1))
{
Sec = "0" + seconds.ToString();
}
else
{
Sec = seconds.ToString();
}
string Totaltime = "Remaing Second: " + Sec;
lblpurgingTimer.Text = Totaltime;
}

I just want to ask that if I can make a stopwatch with C# I tried:
private void button2_Click(object sender, EventArgs e)
{
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
int st = 00;
int m = 00;
string stime = "00:00";
if(st == 60)
{
m++;
st = 00;
}
else
{
st++;
}
if (m == 60)
{
m = 00;
}
if(st < 10)
{
st = 0 + st;
}
if(m < 10)
{
m = 0 + m;
}
stime = m.ToString() + ":" + st.ToString();
label3.Text = stime;
}
this but it didn't worked. My timer is setted up and the interval of the timer is 1000ms. Can someone help me?
It looks to me, that you are more likly to make a watch rather than a stopwatch?
If you're making a stopwatch, I think you need a field/property in your class that holds the starting time:
private DateTime _start;
private void button2_Click(object sender, EventArgs e)
{
_start = DateTime.Now;
timer1.Start();
}
and then in timer1_Tick you can do:
private void timer1_Tick(object sender, EventArgs e)
{
TimeSpan duration = DateTime.Now - _start;
label3.Text = duration.ToString(<some format string>);
}
It seems that your current code in timer1_Tick only has local variables and therefore always will produce the same time? :-)
I have a script based on the countdown timer. I want that when the time reaches 0, the timer stop and a message appear. The code id this:
public partial class simulare : Form
{
private admin admin;
Timer timer = new Timer();
public simulare(admin admin)
{
InitializeComponent();
this.admin=admin;
label2.Text = TimeSpan.FromMinutes(0.1).ToString();
}
private void simulare_Load(object sender, EventArgs e)
{
var startTime = DateTime.Now;
timer = new Timer() { Interval = 1000 };
timer.Tick += (obj, args) =>
label2.Text = (TimeSpan.FromMinutes(0.1) - (DateTime.Now - startTime)).ToString("hh\\:mm\\:ss");
timer.Enabled = true;
timer.Start();
if (condition)
{
timer.Stop();
MessageBox.Show("Done!");
}
}
}
I tried those conditions, but unsuccessful:
if (timer.ToString() == TimeSpan.Zero.ToString())
if (label2.Text.ToString() == TimeSpan.Zero.ToString())
if (label2.Text == TimeSpan.Zero)
You could extract the calculation and assign the result to a TimeSpan variable, then check if the Seconds in that TimeSpan variable are equals to zero
void simulare_Load(object sender, EventArgs e)
{
var startTime = DateTime.Now;
timer = new System.Windows.Forms.Timer() { Interval = 1000 };
timer.Tick += (obj, args) =>
{
TimeSpan ts = TimeSpan.FromMinutes(0.1) - (DateTime.Now - startTime);
label1.Text = ts.ToString("hh\\:mm\\:ss");
if (ts.Seconds == 0)
{
timer.Stop();
MessageBox.Show("Done!");
}
};
timer.Start();
}
First off, checking anything in the Load event isn't going to work. That code only runs once (on form load).
So you need a more complex tick event, which I would put into an actual function instead of a lambda:
private int countDown = 50; //Or initialize at load time, or whatever
public void TimerTick(...)
{
label2.Text = (TimeSpan.FromMinutes(0.1) - (DateTime.Now - startTime)).ToString("hh\\:mm\\:ss");
countDown--;
if (countDown <= 0)
timer.Stop();
}
I use an int counter here since checking against a view property (the text in this case) isn't a very good design/practice. If you really want a TimeSpan, I would still save it off instead of checking directly against the Text property or a string.
I made this code, but there is a delay between the time loop showing on the screen and the exact elapsed time.
Timer t = new Timer();
int time = 15;
string timestr;
t.Interval = 1000;
t.Tick += new EventHandler(Time);
void Time(object sender, EventArgs e)
{
if (time == 0)
{ time = 15; }
if (time != 0)
{
time--;
timestr = time.ToString();
label.Text = timestr;
}
}
My guess is that you are off by one second since the timer won't fire its first event until that interval value is reached.
A quick fix would be to fire the event yourself when you start it:
t.Start();
Time(t, EventArgs.Empty);
I think you need to try this. Add the line Application.DoEvents() just before the end of Time function.
void Time(object sender, EventArgs e)
{
if (time == 0)
{ time = 15; }
if (time != 0)
{
time--;
timestr = time.ToString();
label.Text = timestr;
}
Application.DoEvents();
}
I created a function that gets number of milliseconds and then runs the progress bar but the result is that the progress bar run less time than defined.
this.timerProgress.Tick += new System.EventHandler(this.timerProgress_Tick);
public void AnimateProgBar(int milliSeconds)
{
if (!timerProgress.Enabled)
{
this.Invoke((MethodInvoker)delegate { pbStatus.Value = 0; });
timerProgress.Interval = milliSeconds / 100;
timerProgress.Enabled = true;
}
}
private void timerProgress_Tick(object sender, EventArgs e)
{
if (pbStatus.Value < 100)
{
pbStatus.Value += 1;
pbStatus.Refresh();
}
else
{
timerProgress.Enabled = false;
}
}
using AnimateProgBar(100), will end up creating a Interval of 1 millisecond.
timerProgress.Interval = milliSeconds; //do not divide by 100
this.timerProgress.Tick += new System.EventHandler(this.timerProgress_Tick);
public void AnimateProgBar(int milliSeconds)
{
if (!timerProgress.Enabled)
{
this.Invoke((MethodInvoker)delegate { pbStatus.Value = 0; });
timerProgress.Interval = milliSeconds; //do not divide by 100
timerProgress.Enabled = true;
}
}
private void timerProgress_Tick(object sender, EventArgs e)
{
if (pbStatus.Value < 100)
{
pbStatus.Value += 1;
pbStatus.Refresh();
}
else
{
timerProgress.Enabled = false;
}
}
A call to AnimateProgBar(1000) will result in the following calculation: 1000 / 100. That equals 10.
The Timer interval is already in milliseconds. So you're effectively setting the interval to 10ms.
I would like to know how to create a label that adds sum + 1 every 5 seconds? I've tried with an if loop but unfortunately it resets one second later.
Thank you in advantage for your attention
using System.Diagnostics;
// using system.diagnotics voor stopwatch
namespace WindowsFormsApplication7
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private Stopwatch sw = new Stopwatch();
private void button1_Click(object sender, EventArgs e)
{
timer1.Enabled = true;
sw.Start();
if (timer1.Enabled == true) { button1.Text = "stop"; }
else { button1.Text = "false"; sw.Stop(); }
}
private void timer1_Tick(object sender, EventArgs e)
{
int hours = sw.Elapsed.Hours;
int minutes = sw.Elapsed.Minutes;
int seconds = sw.Elapsed.Seconds;
int sum = 0;
label1.Text = hours + ":" ;
if (minutes < 10) { label1.Text += "0" + minutes + ":"; }
else { label1.Text += minutes + ":"; }
if (seconds < 10) { label1.Text += "0" + seconds ; }
else { label1.Text += seconds ; }
if (seconds ==5) { sum = sum +=1; }
label2.Text = Convert.ToString(sum);
}
}
}
sum should be a class field. Also you can use custom format string for elapsed TimeSpan.
int sum = 0;
private void timer1_Tick(object sender, EventArgs e)
{
// int sum = 0; local variable will be set to zero on each timer tick
label1.Text = sw.Elapsed.ToString(#"hh\:mm\:ss");
// btw this will not update sum each five seconds
if (sw.Elapsed.Seconds == 5)
sum++; // same as sum = sum +=1;
label2.Text = sum.ToString();
}
Your current implementation will increase sum only if current elapsed timeout's second value is five. Which could never happen (depending on your timer interval). If you have timer interval set to 1000 milliseconds, then you can increase sum on each tick, but set label2.Text = (sum % 5).ToString().
every time your stopwatch TICKS, sum is inside TICK and it will reset and start from
int sum=0;
so try to make sum variable GLOBAL outside timer1_Tick event and it will continue increasing.
You will have to move sum out of the timer callback as you are setting it to 0 each time the timer elapses
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private int sum = 0;
private DateTime lastUpdate;
private Stopwatch sw = new Stopwatch();
private void timer1_Tick(object sender, EventArgs e)
{
label1.Text = string.Format("{0:00}:{1:00}:{2:00}",
sw.Elapsed.Hours, sw.Elapsed.Minutes, sw.Elapsed.Seconds);
if (DateTime.Now >= lastUpdate.AddSeconds(5))
{
sum++;
lastUpdate = DateTime.Now;
label2.Text = sum.ToString();
}
}
private void button1_Click(object sender, EventArgs e)
{
if (timer1.Enabled == true)
{
sw.Stop();
button1.Text = "stop";
}
else
{
sum = 0;
lastUpdate = DateTime.Now;
timer1.Enabled = true;
sw.Start();
button1.Text = "Start";
}
}
