Process.Responding-Eigenschaft

Ruft einen Wert ab, der angibt, ob die Benutzeroberfläche des Prozesses reagiert.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

Syntax

'Declaration
Public ReadOnly Property Responding As Boolean
'Usage
Dim instance As Process
Dim value As Boolean

value = instance.Responding

public bool Responding { get; }

public:
property bool Responding {
    bool get ();
}

/** @property */
public boolean get_Responding ()

public function get Responding () : boolean

Eigenschaftenwert

true, wenn die Benutzeroberfläche des zugeordneten Prozesses auf das System reagiert, andernfalls false.

Ausnahmen

Hinweise

Wenn ein Prozess über eine Benutzeroberfläche verfügt, stellt die Responding-Eigenschaft eine Verbindung mit der Benutzeroberfläche her, um zu bestimmen, ob der Prozess auf die Benutzereingabe reagiert. Wenn die Oberfläche nicht sofort reagiert, gibt die Responding-Eigenschaft false zurück. Mit dieser Eigenschaft können Sie ermitteln, ob die Oberfläche des zugeordneten Prozesses nicht mehr reagiert.

Wenn der Prozess nicht über ein MainWindowHandle verfügt, gibt diese Eigenschaft true zurück.

Hinweis zu Windows 98, Windows Millennium Edition: Diese Eigenschaft ist auf dieser Plattform nicht verfügbar, wenn beim Starten des Prozesses ProcessStartInfo.UseShellExecute auf true festgelegt ist.

Beispiel

Im folgenden Beispiel wird eine Instanz von Editor gestartet. Anschließend werden in dem Beispiel verschiedene Eigenschaften des zugeordneten Prozesses abgerufen und angezeigt. Im Beispiel wird festgestellt, wann der Prozess beendet wird, und der Exitcode des Prozesses wird angezeigt.
