My first post... Guess that can be taken as good or bad
So.. I am using a tlb as an interop reference in a VB.Net project that works perfectly fine except for in one property and two of its methods. Other than is one, i am use about 20 or 30 other methods that work just fine.
Catch ex As Exception
the ex.message comes back with
"ByRef value type parameter cannot be null"
the deleteall method doesn't except parameters and it is meant to return a boolean.
I am thinking it is an issue with the interop data type conversion because when I use the OLEviewer the data type is variant_bool, a 2 byte value, and i know that vb.net boolean is 4 byte value, could this be it? if so, can i marshal the response? angain, if so how?
Any ideas would get of great help, my wall is getting sore from my head hitting it too often..
