Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el Increment método y la Value propiedad para incrementar el valor de un ProgressBar en el Tick evento de Timer .The following code example demonstrates how to use the Increment method and the Value property to increment the value of a ProgressBar in the Tick event of a Timer. En el ejemplo también se muestra la Value propiedad en un StatusBarPanel para proporcionar una representación textual de ProgressBar .The example also displays the Value property in a StatusBarPanel to provide a textual representation of the ProgressBar. Este ejemplo requiere que tenga un ProgressBar control, denominado progressBar1 , y un StatusBar control que contenga un StatusBarPanel , denominado statusBarPanel1 .This example requires that you have a ProgressBar control, named progressBar1, and a StatusBar control that contains a StatusBarPanel, named statusBarPanel1. Timer, Denominado time , debe agregarse al formulario como miembro.The Timer, named time, must be added to the form as a member.

private:
   Timer^ time;

   // Call this method from the constructor of the form.
   void InitializeMyTimer()
   {
      // Set the interval for the timer.
      time->Interval = 250;

      // Connect the Tick event of the timer to its event handler.
      time->Tick += gcnew EventHandler( this, &Form1::IncreaseProgressBar );

      // Start the timer.
      time->Start();
   }

   void IncreaseProgressBar( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      // Increment the value of the ProgressBar a value of one each time.
      progressBar1->Increment( 1 );

      // Display the textual value of the ProgressBar in the StatusBar control's first panel.
      statusBarPanel1->Text = String::Concat( progressBar1->Value, "% Completed" );

      // Determine if we have completed by comparing the value of the Value property to the Maximum value.
      if ( progressBar1->Value == progressBar1->Maximum )

      // Stop the timer.
      time->Stop();
   }
private Timer time = new Timer();

// Call this method from the constructor of the form.
private void InitializeMyTimer()

   // Set the interval for the timer.
   time.Interval = 250;
   // Connect the Tick event of the timer to its event handler.
   time.Tick += new EventHandler(IncreaseProgressBar);
   // Start the timer.
   time.Start();
}

private void IncreaseProgressBar(object sender, EventArgs e)

   // Increment the value of the ProgressBar a value of one each time.
   progressBar1.Increment(1);
   // Display the textual value of the ProgressBar in the StatusBar control's first panel.
   statusBarPanel1.Text = progressBar1.Value.ToString() + "% Completed";
   // Determine if we have completed by comparing the value of the Value property to the Maximum value.
   if (progressBar1.Value == progressBar1.Maximum)
      // Stop the timer.
      time.Stop();

   time.Start()
End Sub


Private Sub IncreaseProgressBar(ByVal sender As Object, ByVal e As EventArgs)
   ' Increment the value of the ProgressBar a value of one each time.
   ProgressBar1.Increment(1)
   ' Display the textual value of the ProgressBar in the StatusBar control's first panel.
   statusBarPanel1.Text = ProgressBar1.Value.ToString() + "% Completed"
   ' Determine if we have completed by comparing the value of the Value property to the Maximum value.
   If ProgressBar1.Value = ProgressBar1.Maximum Then
      ' Stop the timer.
      time.Stop()
