Thanks for clarifying tah, save me wasting time trying to make it work.

I'm using this effectively as a subroutine from a VFP application.

Since I have no idea what the difference is between in-process servers and out_of_process. <g> [much as I'd like to, I have no time right now], maybe I can make it into an EXE, I even forget now why I decided to make it a DLL.
