Hi Kevin,

Thanks for the info.

I have a class called MymmPickListBusinessObject which inherits from mmPickListBusinessObject in my business object project. I have a factory method in my Windows application that overrides CreatePickListBusinessObject.


I just want to call MymmPickListBusinessObject when users click on certain mmpicker controls. Someone how the click event of mmpicker control doesn't that triggered when the user clicks on the control. I am having trouble to know which class to return from the factory i.e Return MyBase.CreatePickListBusinessObject() or
Return New MymmPickListBusinessObject


I am basically looking for an event or method or property that I can call so I can flag which class to call from the factory.

Public Overrides Function CreatePickListBusinessObject() As  OakLeaf.MM.Main.Business.mmPickListBusinessObject
                if Flag = "local" then
                  Return MyBase.CreatePickListBusinessObject()
                else
                      Return New MymmPickListBusinessObject
                end if
    End Function

Question 2: I have different Windows application that calls the same WCF Service and have followed the instructions in the dev guide. I have the following key in the app.config file

     <add key="DefaultDataAccessMode" value="wcf" />

and have a factory method in my windows application

                Public Class Factory
    Inherits OakLeaf.MM.Main.Windows.Forms.mmFactoryDesktop

    Public Overrides Function CreateDataAccessObject(ByVal dataAccessClassName As String) As OakLeaf.MM.Main.Data.mmDataAccessBase

        If mmAppBase.DefaultDataAccessMode = mmDataAccessMode.Local Then
            Return MyBase.CreateDataAccessObject(dataAccessClassName)
        Else
            Dim binding As New WSHttpBinding()
            binding.MaxReceivedMessageSize = 147483647
            Dim address As New EndpointAddress("http://ykhanlt/OSPService/Service.svc/mex")
            Return New mmDataAccessWCFSql(binding, address)
        End If

    End Function
End Class

I get the following message "The ConnectionString property has not been initialized"
below is the stack when I try to access data remotely.
