The timer in my opinion is not very accurate when it displays time from its _Tick()
Method. I am wanting to show elapsed time in minutes/seconds show the length of time a procedure takes to complete. I have used this with the Timer but have discovered it's calculations are incorrect. Which is why I wanted to ask would a StopWatch be better to show more accurately or is their a separate control that I should be using altogether?
private int timepassed = 0;
private void buttonFourteen_Click(object sender, DragEventArgs e)
{
timer2.Start();
var backgroundWorker = new BackgroundWorker();
backgroundWorker.DoWork += (s, e) =>
{
//Lengthy Procedure Goes Here
};
backgroundWorker.RunWorkerCompleted += (s, e) =>
{
timer2.Stop();
};
backgroundWorker.RunWorkerAsync();
}
private void timer2_Tick(object sender, EventArgs e)
{
timepassed++;
timedisplay.Text = timepassed.ToString();
}
Here's one way to accomplish this with a stop watch, which should be very accurate:
private readonly Stopwatch sw = new Stopwatch();
private readonly System.Windows.Forms.Timer timer = new System.Windows.Forms.Timer();
public Form1()
{
InitializeComponent();
timer.Tick += timer2_Tick;
}
private void buttonFourteen_Click(object sender, EventArgs e)
{
sw.Restart();
timer.Start();
var backgroundWorker = new BackgroundWorker();
// Simulating a 10-second process for testing
backgroundWorker.DoWork += (s, ea) => Thread.Sleep(TimeSpan.FromSeconds(10));
backgroundWorker.RunWorkerCompleted += (s, ea) => timer.Stop();
backgroundWorker.RunWorkerAsync();
}
private void timer2_Tick(object sender, EventArgs e)
{
timedisplay.Text = sw.Elapsed.ToString("g");
// Or use a custom time format (you can specify precision as well as
// delimiters between days, hours, minutes, seconds, and milliseconds):
// timedisplay.Text = sw.Elapsed.ToString(@"dd\.hh\:mm\:ss\.ff");
}
