UnhandledEvent in VB.NET WinForm

[Ghini76]

Hi Skrusty and congratulations for the work!
I'm running tests with VS2013 and VB.NET Framework 4.0, but I have a problem with the lines:

private ManagerConnection manager = null;
manager = new ManagerConnection (address, port, user, password);
manager.UnhandledEvent + = new ManagerEventHandler (manager_Events);

in VB.NET I translated thus:

 Private Sub Chiama2 ()
     Dim Manag As AsterNET.Manager.ManagerConnection = New AsterNET.Manager.ManagerConnection (My.Settings.Asterisk_host, My.Settings.Asterisk_port, My.Settings.Asterisk_usr, My.Settings.Asterisk_psw)
     Manag.UnhandledEvent = New Manager.ManagerEventHandler (AddressOf Event)
 end Sub

 Private Sub Event ()
      'event handling code
 end Sub

The problem is that "Manag.UnhandledEvent" is not a valid property ...
can you tell me why or how to fix it?

thanks a lot

Ghini

Are you using Source, Release or Nuget and can you confirm the version you're running please?

I'm not very up on VB.NET, but the events that exist on the ManagerConnection class will exist for both VB.NET and C#.

https://github.com/skrusty/AsterNET/blob/master/Asterisk.2013/Asterisk.NET/Manager/ManagerConnection.cs#L166

I ran an example through a c# to vb.net converter and got this. Maybe this will help?

C#

var manager = new ManagerConnection(address, port, user, password);
manager.UnhandledEvent += new ManagerEventHandler(manager_Events);

VB.NET

Dim manager = New ManagerConnection(address, port, user, password)
manager.UnhandledEvent += New ManagerEventHandler(manager_Events)

Hi Ben,

thanks for yopur reply.
I’m using Version 1.0.1 downloaded by NuGet.
In the dropdown missing property UnhandledEvent to assign the event handler…. L

Thanks Fabrizio

Have you tried doing this as per my example above?

[Ghini76]

Yes, but as I said "UnhandledEvent" is not present in the autocompletelist of methods / properties...
I tried it in C# and everything works ...

Hi Ben,

I am having same problem with missing "UnhandledEvent".

any ideas would be appreciated

Do you know of any resources for asternet with vb.net?

Thanks,

DD

I will fire up vs later and have a play with VB.NET. any suggestions welcome as the code for this and all other events is the same!

[garysprice]

there are 2 ways of handling asternet events vb.net. that I know of and use - there maybe more but...

1. 'probably put into your form.load
   'you will have to add handlers for all event manually though. I prefer 2nd option...

Dim Manag As New AsterNET.Manager.ManagerConnection("xxx", xxx, "xxx", "xxx")
AddHandler Manag.UnhandledEvent, AddressOf evManagerUnhandled

Private Sub evManagerUnhandled(sender As Object, e As AsterNET.Manager.Event.ManagerEvent)
'your code goes here
End Sub

2. 'declare the manager as private/public with events

Private WithEvents Manager As New AsterNET.Manager.ManagerConnection("xxx", xxx, "xxx", "xxx")

Private Sub evManagerUnhandledEvent(sender As Object, e As AsterNET.Manager.Event.ManagerEvent) Handles Manager.UnhandledEvent
'your code goes here
End Sub

Here is what I have done in the past

Private Delegate Sub delUnhandled(e As Asterisk.NET.Manager.Event.ManagerEvent)

Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load
     Mancon= New ManagerConnection("xxx", xxx, "xxx", "xxx")
     AddHandler Mancon.UnhandledEvent, AddressOf managerUnhandledEvent
End Sub


Private Sub managerUnhandledEvent(sender As Object, e As Asterisk.NET.Manager.Event.ManagerEvent)
    If InvokeRequired Then
        Me.BeginInvoke(New delUnhandled(AddressOf unhandledEvent), New Object() {e})
    Else
        unhandledEvent(e)
    End If
End Sub


Private Sub unhandledEvent(e As Asterisk.NET.Manager.Event.ManagerEvent)
    'do stuff
End Sub

Hi Guys,

Thanks for your input, much appreciated

as previously suggested, I am now using the following, whic exposes all the
events:
Private WithEvents mgr As New ManagerConnection("192.168.0.198", 5038,
"admin", "amp111")

and then:
Private Sub mgrQueue(ByVal sender As Object, ByVal e As NewStateEvent)
Handles mgr.NewState

    txtMsg.Text += "*** " + e.CallerId + " * " + e.CallerIdNum + " ***"

End Sub

unfortunately, it gets fired multiple times, only the first firing has true
caller info

would using your suggested code fix this?

once again, appreciated.

You'll get a NewState event each time a channel enters a new state! Depending on the state, depends on what information is returned as part of it.

Are all the events for the same channel?

Not sure technically this is an issue. AMI is about state modelling, you can't assume an event is atomic in it's own right but part of a sequence of events describing the state of a channel, for example.

[dgrah]

Check e.Channel, e.ChannelState and e.ChannelStateDesc to see what the New State is about.
