How you setup and call a DLL from VFP 3.0 depends on what version of Windows you're using. If it's Win 3.1x then you must use the RegFN()/CallFN functions in Foxtools. If it's 32 bit Windows (95, NT) then you can use the DECLARE - DLL syntax, and call the function as you would any other. You can still use the RegFN/CallFN syntax, but I personally feel that the DECLARE syntax is a lot more understandable. If you can let me know the function(s) you're interested in calling and the platform, I'll see what I can do to help.
