Ok, I can't say I fully understand what you are doing here, but I think
I see some issue that may help you.
1. 'Dim BInfo(,) As Object 'passed in byref
Objects will always be passed by reference. Only native data types are
able to be passed by value.
2. NodetoSet = BINFO
This is setting NodetoSet to the same as Binfo. They both point to the
same data object now.
Hope this helps.
