Gets the primary display.
(in System.Windows.Forms.dll)
Visual Basic (Declaration)
Public Shared ReadOnly Property PrimaryScreen As Screen
Dim value As Screen
value = Screen.PrimaryScreen
public static Screen PrimaryScreen { get; }
public:
static property Screen^ PrimaryScreen {
Screen^ get ();
}
public static function get PrimaryScreen () : Screen
For a single display system, the primary display is the only display.
The following code example demonstrates the use of PrimaryScreen property and the GetWorkingArea method. This method requires a form containing a button named Button1
' This method will adjust the size of the form to utilize
' the working area of the screen.
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
' Retrieve the working rectangle from the Screen class
' using the PrimaryScreen and the WorkingArea properties.
Dim workingRectangle As System.Drawing.Rectangle = _
Screen.PrimaryScreen.WorkingArea
' Set the size of the form slightly less than size of
' working rectangle.
Me.Size = New System.Drawing.Size(workingRectangle.Width - 10, _
workingRectangle.Height - 10)
' Set the location so the entire form is visible.
Me.Location = New System.Drawing.Point(5, 5)
End Sub
// This method will adjust the size of the form to utilize
// the working area of the screen.
private void Button1_Click(System.Object sender, System.EventArgs e)
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System.Drawing.Rectangle workingRectangle =
Screen.PrimaryScreen.WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this.Size = new System.Drawing.Size(
workingRectangle.Width-10, workingRectangle.Height-10);
// Set the location so the entire form is visible.
this.Location = new System.Drawing.Point(5, 5);
}
// This method will adjust the size of the form to utilize
// the working area of the screen.
private:
void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
{
// Retrieve the working rectangle from the Screen class
// using the PrimaryScreen and the WorkingArea properties.
System::Drawing::Rectangle workingRectangle = Screen::PrimaryScreen->WorkingArea;
// Set the size of the form slightly less than size of
// working rectangle.
this->Size = System::Drawing::Size( workingRectangle.Width - 10, workingRectangle.Height - 10 );
// Set the location so the entire form is visible.
this->Location = System::Drawing::Point( 5, 5 );
}
and the GetWorkingArea method.
