The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Do you want to display an elapsed time? Say the time spent on the activity driving the progress bar so far?

Hi NurveTech;

Place a Timer control on to the form and set its Interval property to 1000 and its Enable property to false which should be the default. The when you need to start the progress bar turn on the timer with a statement like this.

        timer1.Enabled = true;

This event will be called once a second.

        private void timer1_Tick(object sender, EventArgs e)
        {
            // Update progress bar
            progressBar1.Increment(1);
            if (progressBar1.Value == progressBar1.Maximum)
            {
                progressBar1.Value = 0;
            }
        }

        // The to turn off the progress bar stop the timer like this.
        timer1.Enabled = false;

Now be aware that this code will not work well if you are doing a long process if the process does not do a Application.DoEvents(); or the process is running in a separate thread.

I want to display a timer that goes up every second so it looks like

0:1...0:23...0:56...1:13

after it gets to 60 seconds i want it to increase the minute by one, then start the second count over again.

This should do what you need.

using System.Diagnostics;
using System.Timers;

        private delegate void SetLabelDelegate();
        private string TimeInString = String.Empty;
        private Stopwatch sw = new Stopwatch();
        private System.Timers.Timer timer1 = new System.Timers.Timer();

        private void Form1_Load(object sender, EventArgs e)
        {
            timer1.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
        }

        private void OnTimedEvent(object source, ElapsedEventArgs e)
        {
            TimeInString = sw.Elapsed.Minutes.ToString("00") + ":" +
                sw.Elapsed.Seconds.ToString("00");
            SetLabel();
        }

        private void SetLabel()
        {
            if (label1.InvokeRequired)
            {
                SetLabelDelegate setlabel = new SetLabelDelegate(SetLabel);
                this.Invoke(setlabel);
            }
            else
            {
                label1.Text = TimeInString;
            }
        }


Use this code when you want to start the timing.

            sw.Reset();
            TimeInString = "0:0";
            sw.Start();
            timer1.Enabled = true;

And use this code when you want to stop the timer.

            sw.Stop();
            sw.Reset();
            timer1.Enabled = false;

Use a Timer control (System.Windows.Forms.Timer).
Set the Interval property to 1000 (melliseconds) and place your code inside the Timer.Tick event handler.
Call the Timer.Start method to start the timer.
