Environment.UserInteractive Property (System)

.NET Framework Class Library

Environment..::.UserInteractive Property

Gets a value indicating whether the current process is running in user interactive mode.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

Public Shared ReadOnly Property UserInteractive As Boolean

Visual Basic (Usage)

Dim value As Boolean

value = Environment.UserInteractive

public static bool UserInteractive { get; }

Visual C++

public:
static property bool UserInteractive {
    bool get ();
}

JScript

public static function get UserInteractive () : boolean

Property Value

Type: System..::.Boolean
true if the current process is running in user interactive mode; otherwise, false.

Remarks

The UserInteractive property reports false for a Windows process or a service like IIS that runs without a user interface. If this property is false, do not display modal dialogs or message boxes because there is no graphical user interface for the user to interact with.

The following code example displays whether the current process is running in user interactive mode.
