Solution 1

Try:

Using con As New SqlConnection(strConnect)
	con.Open()
	Using com As New SqlCommand("SELECT dbo.MyFunctionName()", con)
		Using reader As SqlDataReader = com.ExecuteReader()
			While reader.Read()
				Dim i As Integer = CInt(reader(0))
                                Dim b As Boolean = i = 0
				...
			End While
		End Using
	End Using
End Using

I thought you didn't touch VB.Net. :-)
It was almost flawless, but alas, this construct won't work: Dim b As Boolean = i = 0
I'd recommend: Dim b As Boolean = IF(i = 0,True,False)

Are you sure?

    Sub Main()
        Dim i As Integer = 0
        For i = 0 To 2
            Dim b As Boolean = i = 0
            Console.WriteLine(b)
        Next
        Console.ReadLine()
    End Sub

Results:
True
False
False

I'm stumped!
It's one of these things I've "known" since forever. I'll have to check if I've always been wrong or if they have changed it.
