How to read a Hyperion bqy fille in Visual Basic 2012?

Question

Code
Dim objBqyApp As BrioQry.Application
objBqyApp = New BrioQry.Application

Unable to cast COM object of type 'System.__ComObject' to interface type 'BrioQry.Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{5D2B9A02-4F48-11D2-B1A6-00104B67DFD5}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."

Answer 1

Dim obj As New BrioQry.Application 
Dim doc As BrioQry.Document 
Dim querysection As BrioQry.Section 

Set doc = obj.Documents.Open("C:\Program Files\Brio\BrioQuery\Sandbox.bqy") 
Set querysection = doc.Sections.Item("Query")

Wrong, is is the code for Visual Basic 6.0. When I try to run it in VB.Net I get the error on the line

Dim objBqyApp as New BrioQry.Application

I need to know the code changes for VB.Net and if there is a dll or reference change
