SystemSettings クラス

デバイスのユーザーインターフェイス、およびネイティブ Windows CE オペレーティングシステム設定にアクセスできるようにします。

名前空間: Microsoft.WindowsCE.Forms
アセンブリ: Microsoft.WindowsCE.Forms (microsoft.windowsce.forms.dll 内)
構文

Visual Basic (宣言)

Public NotInheritable Class
 SystemSettings

Visual Basic (使用法)

Dim instance As SystemSettings

public sealed class SystemSettings

C++

public ref class SystemSettings sealed

public final class SystemSettings

JScript

public final class SystemSettings

解説

現在、このクラスで設定できるのは、ScreenOrientation プロパティの設定だけです。

使用例

デバイスの画面の向きを、通常のゼロ度の縦表示から 90 度、180 度、270 度に順に回転し、最後にゼロ度に戻す方法を次のコード例に示します。ボタンをクリックするたびに、ScreenOrientation 列挙体を循環します。
