Que muestra una forma de Windows en un monitor secundario?

Question

Estoy tratando de establecer un formulario Windows en el monitor secundario, de la siguiente manera:

private void button1_Click(object sender, EventArgs e)
{
    MatrixView n = new MatrixView();
    Screen[] screens = Screen.AllScreens;
    setFormLocation(n, screens[1]);
    n.Show();
}

private void setFormLocation(Form form, Screen screen)
{
    // first method
    Rectangle bounds = screen.Bounds;
    form.SetBounds(bounds.X, bounds.Y, bounds.Width, bounds.Height);

    // second method
    //Point location = screen.Bounds.Location;
    //Size size = screen.Bounds.Size;

    //form.Left = location.X;
    //form.Top = location.Y;
    //form.Width = size.Width;
    //form.Height = size.Height;
}

Las propiedades de los límites parecen correctas, pero en los dos métodos que he probado, esto maximiza la forma en el monitor principal. ¿Alguna idea?

Answer 1

Trate de ajuste de parámetros WindowStartUpLocation como "manual" dentro de su método SetFormLocation.

Answer 2

this.Location = Screen.AllScreens[1].WorkingArea.Location;

este es el formulario de referencia.

@ respuesta de Gengi es sucinta y funciona bien. Si se maximiza la ventana no se mueve la ventana. Este fragmento de código que resuelve (aunque sospecho que las ventanas de dimensiones "normales" deben ser menores que las nuevas dimensiones de la pantalla para que esto funcione):

    void showOnScreen(int screenNumber)
    {
        Screen[] screens = Screen.AllScreens;

        if (screenNumber >= 0 && screenNumber < screens.Length)
        {
            bool maximised = false;
            if (WindowState == FormWindowState.Maximized)
            {
                WindowState = FormWindowState.Normal;
                maximised = true;
            }
            Location = screens[screenNumber].WorkingArea.Location;
            if (maximised)
            {
                WindowState = FormWindowState.Maximized;
            }
        }
    }

¿Está seguro screens[1] es su secundaria? screens[0] darle una oportunidad. Su código es básicamente correcto.

Ok, he comprobado, que tendrá que hacerlo después del show ():

n.Show();
setFormLocation(n, screens[1]);

lo que da una parpadeo no deseado. Sin embargo, es probable que pueda hacer:

n.SetBounds(-100, -100, 10, 10);  // or similar
n.Show();
setFormLocation(n, screens[1]);

Answer 5

He utilizado este para una aplicación XNA 4 Dual Screen (Pantalla completa Ventana XNA Game + WinForm)

En el método Form_Load (), coloque el código siguiente:

var primaryDisplay = Screen.AllScreens.ElementAtOrDefault(0);  
var extendedDisplay = Screen.AllScreens.FirstOrDefault(s => s != primaryDisplay) ?? primaryDisplay;

this.Left = extendedDisplay.WorkingArea.Left + (extendedDisplay.Bounds.Size.Width / 2) - (this.Size.Width / 2);
this.Top = extendedDisplay.WorkingArea.Top + (extendedDisplay.Bounds.Size.Height / 2) - (this.Size.Height / 2);

Answer 6

Para mostrar la forma en la pantalla secundaria:

    Screen primaryFormScreen = Screen.FromControl(primaryForm);
    //Use this if you are looking for secondary screen that is not primary
    Screen secondaryFormScreen = Screen.AllScreens.FirstOrDefault(s => !s.Primary) ?? primaryFormScreen;
    //Use this if you are looking for screen that is not being used by specific form
    Screen secondaryFormScreen = Screen.AllScreens.FirstOrDefault(s => !s.Equals(primaryFormScreen)) ?? primaryFormScreen;
    //Putting the form on the other screen
    secondaryForm.Left = secondaryFormScreen.Bounds.Width;
    secondaryForm.Top = secondaryFormScreen.Bounds.Height;
    //Recommended to use, You can change it back later to the settings you wish
    secondaryForm.StartPosition = FormStartPosition.Manual;
    secondaryForm.Location = secondaryFormScreen.Bounds.Location;
    Point p = new Point(secondaryFormScreen.Bounds.Location.X, secondaryFormScreen.Bounds.Location.Y);
    secondaryForm.Location = p;
    secondaryForm.Show();

Si usted está mirando adelante para una pantalla específica, puede recorrer en "Screen.AllScreens" y utilizar el proceso anterior.

Answer 8

  Screen[] screens = Screen.AllScreens;
                sc aoc = new sc();
                aoc.Show();
    aoc.Location = Screen.AllScreens[INDEX OF YOUR AVAILABLE SCREENS TARGET].WorkingArea.Location;

  

PARA ventana maximizada ESTADO

aoc.WindowState = FormWindowState.Maximized;

  

PARA CUALQUIER posición x, y

aoc.Location = new Point(TARGET X POSITION, TARGET Y POSITION);
