定时器控制使用动态控制 [英] Timer control using dynamic control

问题描述

我在Dynamic中尝试过Timer控件但它会抛出一个错误，因为ConsoleApplicationworking.exe中发生了'System.NullReferenceException'类型的未处理异常

附加信息：对象引用未设置为对象的实例

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"

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");
           }

       }

亲切解决这个问题。



我的尝试：

Kindly solve this problem.

What I have tried:

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");
            }

        }

推荐答案

这可能只是一个文书错误。



您的代码是：

This is probably just a clerical error.

Your code is:

new Timer();

而不是：

instead of:

Tims= new Timer();
