Event Handling

[Morten Fagermoen]

Hello!

I would like to make an event handler in a VB.NET 2005 project to check if
the battery state changes on my Windows Mobile 5 device. But I don't manage
to make this work, does anyone have an example for me?

Her is a cut from my code:

Public Shadows Event Changed As ChangeEventHand ler

Private Sub PhoneInfo_Load( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Dim statePowerBatte ryStrength As New
SystemState(Sys temProperty.Pow erBatteryStreng th)
AddHandler statePowerBatte ryStrength.Chan ged, AddressOf
ChangedPowerBat teryStrength
End Sub

Private Sub ChangedPowerBat teryStrength()
ShowInfo()
End Sub
*************** *
The statement ....,AddressOf ChangedPowerBat teryStrength gives me an error
that says:

Method 'Private Sub ChangedPowerBat teryStrength()' does not have the same
signature as delegate 'Delegate Sub ChangeEventHand ler(sender As Object,
args As Microsoft.Windo wsMobile.Status .ChangeEventArg s)'.

Re: Event Handling

Make shure that the ChangedPowerBat teryStrength() accepts the same
types of parameters as the ChangeEventHand ler delegate.

In your case you have to add: sender As Object,
args As Microsoft.Windo wsMobile.Status .ChangeEventArg s
