Trying my question again from different code editor. I can get realtime data from the api using v...

kent_finkle

...b but not the non-realtime data. Hoping the form doesn't munge the code from this editor.

    tc = GetTickCount

    While GetTickCount < tc + Milliseconds
        Sleep 1

You're not initializing Dex2 Manager correctly. You're missing a cast from Dex2Mgr class to IDex2Mgr2 interface, which is required. See VB code sample in this tutorial, Step2 - Create DEX2 object and initialize DEX2.
