Very interesting article Herve, though I found it tweaking my curiosity from another angle.

Spent a few days leisurely trying to coerce VB(6) into creating a 'special' extended stored proc DLL which SQL Server could call, as a registered, external stored procedure, just as you're doing here. But eventually my efforts came to a halt as it appeared that it would be necessary to either create an instance of the DLL using sp_OACreate (which I could implement, but didn't want to do for various reasons), or write a DLL with the header that SQL Server expects using Visual C++ (which I've not got).

Question is....does SQL Server 2000 interface with 'normal' DLLs (unlikely)

-or-

is MSVBVM60.DLL 'SQL Server ready' with the header.

Or is it simply that I'm being dim? (probably) 😀
