"can not return variants" when using c++ dll

P: n/a

I'm trying to call a function from a C++ dll which is declared as


This function (which I can't change) executes a SQL query and returns a
single value - whatever the query asks for: integer, string, double

My declaration for that in VB.NET 2003 is

Private Declare Auto Function ExecuteFunction Lib "database.dll" ( _
ByVal sSQL As Char) As Object

Whenever I call that function, I'm getting the "PInvoke restriction:
can not return

How can I fix that?
