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 ChangeEventHandler

Private Sub PhoneInfo_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim statePowerBatteryStrength As New
SystemState(SystemProperty.PowerBatteryStrength)
AddHandler statePowerBatteryStrength.Changed, AddressOf
ChangedPowerBatteryStrength
End Sub

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

Method 'Private Sub ChangedPowerBatteryStrength()' does not have the same
signature as delegate 'Delegate Sub ChangeEventHandler(sender As Object,
args As Microsoft.WindowsMobile.Status.ChangeEventArgs)'.

Make shure that the ChangedPowerBatteryStrength() accepts the same
types of parameters as the ChangeEventHandler delegate.

In your case you have to add: sender As Object,
args As Microsoft.WindowsMobile.Status.ChangeEventArgs
