Hi sbtbill,

I am going to move your post to the Sage 50 SDK forum. That forum has more active users of the SDK.

I think I'm moving forward.  Got this code to run without error in VB 2013

<Window x:Class="MainWindow"

   xmlns="schemas.microsoft.com/.../presentation"

   xmlns:x="schemas.microsoft.com/.../xaml"

   Title="MainWindow" Height="350" Width="525">

'Public Class Form1

dim ptapp as Interop.Peachserver.Application

dim ptloginSelect as Interop.PeachServer.LoginSelector

dim ptlogin as Interop.PeachServer.Login

'

ptloginselcet = New Interop.PeachServer.Loginselector()

ptlogin = ptloginSelect.GetCurrentLoginSelector()

'

ptlogin = ptlogin.GetApplication("","")

'

'End Class

</Window>

Think I still have a lot to do but it feels great to have a start.
