Steve,

You probably don't have the environment setup right. Remember your DLL is going to fire up with all the default SET values. For example here's some code from a server I'm working on:

close database all
set talk off
set safety off
set exclusive off
set deleted on
set century on
set century to 19 rollover 95
set multilocks on
set console off
set resource off

on shutdown *

local lcDrive

if ( "DFSD" $ getenv( "machine" ) )
   if ( "Pentium-II" $ getenv( "machine" ) )
      lcDrive = "e:"
   else
      lcDrive = "h:"
   endif
else
   lcDrive = "c:"
endif

set default to (lcDrive + "\vfp5app\project")

Is the database already open in another VFP session?

>I'm getting a "File Access denied" error message from within my DLL when trying to issue the VFP "OPEN DATABASE" command. I have successfully created the DLL with various class definitions in it and can instantiate objects using it. Are there certain VFP commands that a DLL will not process? My test program makes sure that the database is closed.
