See more:

I have tried Timer control in Dynamic but it throws an error as "An unhandled exception of type 'System.NullReferenceException' occurred in ConsoleApplicationworking.exe"
"Additional information: Object reference not set to an instance of an object"

C#

private Timer Tims;
protected void SetControl()
       {
         new Timer();
         Tims.Tick += new EventHandler(timer1_Tick);
       }

private void StartBtn_Click(object sender, EventArgs e)
       {

           if (Stimer != 0)
           {
               Tims.Interval = Stimer;
               Tims.Enabled = true;
               Tims.Start();
           }
           else
           {
               MessageBox.Show("Select TimerInterval");
           }

       }

Kindly solve this problem.

What I have tried:

C#

int Stimer=1000;(From User)
 private Timer Tims;
 protected void SetControl()
        {
          new Timer();
          Tims.Tick += new EventHandler(timer1_Tick);
        }

 private void StartBtn_Click(object sender, EventArgs e)
        {

            if (Stimer != 0)
            {                
                Tims.Interval = Stimer;
                Tims.Enabled = true;
                Tims.Start();
            }
            else
            {
                MessageBox.Show("Select TimerInterval");
            }

        }

Tims= new Timer(); instead of simply new Timer();.

Done, thanks.

The previous comment is the answer to your question, but for future reference, if you get an error, it tells you exactly what is happening. And if you pay attention to what line of code is causing the error you would soon see that you are trying to reference something that is null, which is a very, very easy problem to fix on your own.

Solution 1

This is probably just a clerical error.

Your code is:

C#

new Timer();

instead of:

C#

Tims= new Timer();
