Public Class Screen
Dim instance As Screen

Not applicable.

The constructor for this object is not public, so you cannot explicitly create a Screen object. The object is created when you call its public methods.

The following code example shows how to use various methods and properties of the Screen class. The example calls the AllScreens property to retrieve an array of all the screens connected to the system. For each returned Screen, the example adds the device name, bounds, type, working area, and primary screen to a ListBox.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnGetScreenInfo.Click

    Dim Index As Integer
    Dim UpperBound As Integer

    ' Gets an array of all the screens connected to the system.

    Dim Screens() As System.Windows.Forms.Screen = _
    UpperBound = Screens.GetUpperBound(0)

    For Index = 0 To UpperBound

        ' For each screen, add the screen properties to a list box.

        ListBox1.Items.Add("Device Name: " + Screens(Index).DeviceName)
        ListBox1.Items.Add("Bounds: " + Screens(Index).Bounds.ToString())
        ListBox1.Items.Add("Type: " + Screens(Index).GetType().ToString())
        ListBox1.Items.Add("Working Area: " + Screens(Index).WorkingArea.ToString())
        ListBox1.Items.Add("Primary Screen: " + Screens(Index).Primary.ToString())


End Sub

private void button1_Click(Object sender, System.EventArgs e)
    int index;
    int upperBound;
    // Gets an array of all the screens connected to the system.
    Screen screens[] = Screen.get_AllScreens();
    upperBound = screens.GetUpperBound(0);

    for (index = 0; index <= upperBound; index++) {
        // For each screen, add the screen properties to a list box.
        listBox1.get_Items().Add("Device Name: " + screens[index].
        listBox1.get_Items().Add("Bounds: " + screens[index].get_Bounds()
        listBox1.get_Items().Add("Type: " + screens[index].GetType().
        listBox1.get_Items().Add("Working Area: " + screens[index].
        listBox1.get_Items().Add("Primary Screen: " + 
} //button1_Click
