Timer::Start Method ()

 

Starts the timer.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public:
void Start()

You can also start the timer by setting the Enabled property to true.

The following code example implements a simple interval timer, which sets off an alarm every five seconds. When the alarm occurs, a MessageBox displays a count of the number of times the alarm has started and prompts the user whether the timer should continue to run.

public ref class Class1
{
private:
   static System::Windows::Forms::Timer^ myTimer = gcnew System::Windows::Forms::Timer;
   static int alarmCounter = 1;
   static bool exitFlag = false;

   // This is the method to run when the timer is raised.
   static void TimerEventProcessor( Object^ /*myObject*/, EventArgs^ /*myEventArgs*/ )
   {
      myTimer->Stop();

      // Displays a message box asking whether to continue running the timer.
      if ( MessageBox::Show( "Continue running?", String::Format( "Count is: {0}", alarmCounter ), MessageBoxButtons::YesNo ) == DialogResult::Yes )
      {

         // Restarts the timer and increments the counter.
         alarmCounter += 1;
         myTimer->Enabled = true;
      }
      else
      {

         // Stops the timer.
         exitFlag = true;
      }
   }


public:
   static void Main()
   {

      /* Adds the event and the event handler for the method that will 
                process the timer event to the timer. */
      myTimer->Tick += gcnew EventHandler( TimerEventProcessor );

      // Sets the timer interval to 5 seconds.
      myTimer->Interval = 5000;
      myTimer->Start();

      // Runs the timer, and raises the event.
      while ( exitFlag == false )
      {

         // Processes all the events in the queue.
         Application::DoEvents();
      }
   }

};

int main()
{
   Class1::Main();
}
