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();
}
Private time As New Timer()

' Call this method from the constructor of the form.
Private Sub InitializeMyTimer()
   ' Set the interval for the timer.
   time.Interval = 250
   ' Connect the Tick event of the timer to its event handler.
   AddHandler time.Tick, AddressOf IncreaseProgressBar
   ' Start the timer.
   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()
   End If
End Sub

El Increment método permite incrementar el valor de la barra de progreso en una cantidad específica.The Increment method enables you to increment the value of the progress bar by a specific amount. Este método de incrementar la barra de progreso es similar al uso de la Step propiedad con el PerformStep método.This method of incrementing the progress bar is similar to using the Step property with the PerformStep method. La Value propiedad especifica la posición actual del ProgressBar .The Value property specifies the current position of the ProgressBar. Si, después de llamar al Increment método, la Value propiedad es mayor que el valor de la Maximum propiedad, la Value propiedad permanece en el valor de la Maximum propiedad.If, after calling the Increment method, the Value property is greater than the value of the Maximum property, the Value property remains at the value of the Maximum property. Si, después de llamar al Increment método con un valor negativo especificado en el value parámetro, la Value propiedad es menor que el valor de la Minimum propiedad, la Value propiedad permanece en el valor de la Minimum propiedad.If, after calling the Increment method with a negative value specified in the value parameter, the Value property is less than the value of the Minimum property, the Value property remains at the value of the Minimum property.

Dado ProgressBar que un objeto cuyo estilo se establece en Marquee muestra una barra de desplazamiento continuamente en lugar de su Value , Increment no es necesario llamar a y generará una InvalidOperationException .Because a ProgressBar object whose style is set to Marquee displays a continuously scrolling bar instead of its Value, calling Increment is unnecessary and will raise an InvalidOperationException.
