SystemState Class

3/29/2010

Gives the ability to get the current value of a system state as well as the ability to be notified when that state changes

Namespace: Microsoft.WindowsMobile.Status
Assembly: Microsoft.WindowsMobile.Status (in microsoft.windowsmobile.status.dll)

Syntax

public class SystemState : StateBase, IDisposable

'Declaration
Public Class SystemState
    Inherits StateBase
    Implements IDisposable

Remarks

When defining an instance of SystemState that is going to handle the Changed event, make sure that the instance is defined globally in the class where the event will be handled. If it is defined in a method, it will be up for garbage collection after it goes out of scope.

public class MyClass
{
    SystemState state; // defined globally to class
    private void Form1_Load(object sender, EventArgs e)
    {
        // SystemState state;  // This instance will go out of scope if defined here

        state =  new SystemState(SystemProperty.OwnerName);
        state.Changed += new ChangeEventHandler(state_Changed);
    }
}
