Ejemplos

En el ejemplo de código siguiente se implementa un temporizador de intervalo simple, que establece una alarma cada cinco segundos. Cuando se produce la alarma, muestra MessageBox un recuento del número de veces que se ha iniciado la alarma y pregunta al usuario si el temporizador debe seguir ejecutándose.

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();
      }
   }

};
