Hi Silvio,

Once again thank you for your engagement.
Upgrade to 6.0.9 did solve my problem with the
Coroutine.Start.

Hi THWI,
 
So, the errors you were getting are in fact compilation errors?
I did test with DeVForce6.0.9.
Did upgrading to 6.0.9 solved your issue?
 
Regards,
   Silvio.

Hi Silvio and many thanks for your reply.
 
As you tell me that the code snippet compiles ok at your computer, I checked out my version of DevForce.
My version is 6.0.8, and I suppose I will need 6.0.9 which contains additional overloads of Croutine.Start.
 
Regards THWI.

 Hi THWI,

The snippet you provided looks ok.
It also executes without problems here.
Here's a simple solution with your snippet where everything works fine: uploads/892/VBCoroutine.zip
 
Are you getting this error during compilation or at runtime? What version of DevForce are you running?
 
Can you upload a simple solution reproducing the issue?
 
Silvio.

Has implemented exactly as described, but get this error:
 
Error 3 Overload resolution failed because no accessible 'Start' can be called without a narrowing conversion:
 'Public Shared Function Start(
  coroutine As System.Func(Of System.Collections.Generic.IEnumerable(Of IdeaBlade.EntityModel.INotifyCompleted)),
  [completedHandler As System.Action(Of IdeaBlade.EntityModel.CoroutineOperation) = Nothing])
  As IdeaBlade.EntityModel.CoroutineOperation':
  Argument matching parameter 'coroutine' narrows

   to   'System.Func(Of System.Collections.Generic.IEnumerable(Of IdeaBlade.EntityModel.INotifyCompleted))'. 
 
MY CODE IS AS FOLLOWS:
Can someone tell me whats wrong.
 
Function LoadAll(ByVal manager As myEntityManager) As IEnumerable(Of Func(Of INotifyCompleted))
 
' List of asynchronous functions for the Coroutine to execute serially
Dim funcList = New List(Of Func(Of INotifyCompleted))
 
' Get all
Dim loadFnc As Func(Of INotifyCompleted) = _
Function()
    Return manager.Customers.ExecuteAsync() ' return an INotifyCompleted
End Function
 
funcList.Add(loadFnc)
 
' return the list
Return funcList
 
End Function
 
 
 
' Sequence from my main routine
 
Dim op = Coroutine.Start(LoadAll(_eMgr))
AddHandler op.Completed, _
  Sub(s As Object, e As CoroutineCompletedEventArgs)
    If e.CompletedSuccessfully Then
      Debug.Write("All were loaded")
    Else
      Debug.Write(e.Error.Message)
    End If
  End sub
