SystemSettings Class

Provides access to user interface and native Windows CE operating system settings on a device.

Namespace: Microsoft.WindowsCE.Forms
Assembly: Microsoft.WindowsCE.Forms (in microsoft.windowsce.forms.dll)

public sealed class SystemSettings
public final class SystemSettings
public final class SystemSettings
Not applicable.

Currently, this class provides settings for the ScreenOrientation property only.

The following code example demonstrates how to rotate the screen orientation of a device from the normal portrait view at zero degrees to 90, then to 180, then to 270, and then back to zero degrees. Each button click cycles through the ScreenOrientation enumeration.

using System;
using System.Drawing;
using System.Collections;
using System.Windows.Forms;
using System.Data;
using Microsoft.WindowsCE.Forms;

namespace SystemSettingsTest
public class Form1 : System.Windows.Forms.Form
 private System.Windows.Forms.Button button1;
 private System.Windows.Forms.MainMenu mainMenu1;
 private System.Windows.Forms.StatusBar statusBar1;

 // Set a variable to be incremented by button clicks
 // that will change the orientation by rotating
 // through the ScreenOrientation enumeration.
 int x = 0;

 public Form1()

  this.MinimizeBox = false;

  // Set the screen orientation to normal
  // and display the value on the status bar.
  SystemSettings.ScreenOrientation = ScreenOrientation.Angle0;
  this.statusBar1.Text = SystemSettings.ScreenOrientation.ToString();

 protected override void Dispose( bool disposing )
  base.Dispose( disposing );
 #region Windows Form Designer generated code
 private void InitializeComponent()
  this.mainMenu1 = new System.Windows.Forms.MainMenu();
  this.button1 = new System.Windows.Forms.Button();
  this.statusBar1 = new System.Windows.Forms.StatusBar();
  // button1
  this.button1.Location = new System.Drawing.Point(16, 128);
  this.button1.Text = "Rotate";
  this.button1.Click += new System.EventHandler(this.button1_Click);
  // Form1
  this.Menu = this.mainMenu1;
  this.Text = "Orientation Demo";
 static void Main()
  Application.Run(new Form1());

  // Each click event changes the screen orientation, as determined
  // by the variable x, which increments from 0 to 3 and then back
  // to 0. Four clicks cycle through the ScreenOrientation enumeration.

 private void button1_Click(object sender, System.EventArgs e)

   case 0:

    // Pass a value for the ScreenOrientation enumeration
    // to the SetOrientation method, defined below,
    // and increment x so that the next button
    // click rotates the screen orientation.
   case 1:
   case 2:
   case 3:
    x = 0;
    x = 0;

  // Set the orientation to a value of the
  // ScreenOrienation enumeration and update the
  // status bar with the current angle.
 private void SetOrientation(ScreenOrientation so)
  // Set the requested orientation.

  SystemSettings.ScreenOrientation = so;

  this.statusBar1.Text = SystemSettings.ScreenOrientation.ToString();
