David,

It sounded like a great idea, and I'm sure it is, but we must be doing something wrong, because even when declaring the functions, the DLL does not work.

Registering goes ok, but when calling the function(s), the DLL won't load.

Like I wrote, I'm no C hawk, so I hav no idea if the guy's doing it right - but he assured me he went by the book on this.

Are the any secrets we might have missed out on? Header files, libraries & stuff?

TIA

There are two different VC++ sample projects and the VFP code to access the DLLs over on my website. They are under the Samples section SpyIn and DeQuote.
