Re: PL/SQL extenrla procedures (8i 8.1.6.0 WinNT DLLs)

;-) Well, if the server is *this machine* .. me ? Your reply would obviously explains why Createfile doesn't work :-| By the way, according to the documentation, PL/SQL external procedures don't support remote calls, so could *never* be executed on another machine.

As I've had no constructive responses from two forums, I have to assume the worst .. that EXTPROC.EXE doesn't support the Windows API - probably doesn't handle windows messages. Which means that you can use it for toy-town DLLs, but little else.
