MobileDevice.Hibernate Event

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Provides access to the WM_HIBERNATE message in Windows CE.

Namespace:  Microsoft.WindowsCE.Forms
Assembly:  Microsoft.WindowsCE.Forms (in Microsoft.WindowsCE.Forms.dll)

Syntax

'Declaration
Public Shared Event Hibernate As EventHandler
'Usage
Dim handler As EventHandler

AddHandler MobileDevice.Hibernate, handler
public static event EventHandler Hibernate
public:
static  event EventHandler^ Hibernate {
    void add (EventHandler^ value);
    void remove (EventHandler^ value);
}
member Hibernate : IEvent<EventHandler,
    EventArgs>

Remarks

When memory pressure from running applications is intensive, Windows CE sends the WM_HIBERNATE message to top level windows. You can respond to this event in managed code with the Hibernate event.

You can provide code in an event handler to reduce resource usage to accommodate memory pressure from other applications running on the device. This event is specific only to the current thread.

Examples

The following code example shows how to add and use an event handler for the Hibernate event.

' Connect an event handler, 
' OnHibernate, to the Hibernate event.
AddHandler MobileDevice.Hibernate, AddressOf OnHibernate
// Connect an event hander, OnHibernate, to the Hibernate event.
MobileDevice.Hibernate += new EventHandler(OnHibernate);
' Respond to the Hibernate event.
Private Sub OnHibernate(sender As Object, e As EventArgs)

 ' Add code here to release cached resources
 ' for relieving memory pressure.

End Sub
private void OnHibernate(object sender, EventArgs e)
{
   // Add code here to release cached resources
   // for relieving memory pressure.
