Jason,
Exporting the functions applies only to API type DLLs that you make with C/C++. You gain access to these functions using the DECLARE command. VFP DLLs are COM objects, they are accessed by oSomeServer = createobject( "YourDLLFileName.YourOLEPublicClassName" ). All methods/properties of the class that are marked as public will be available to the client using your COM object.
>You may also have a problem with there not being an entry point into the DLL. You have to export the functions/methods specifically. It is the end of the day, and the specifics are eluding me at the moment. I'll post a specific answer in a little while. Tomorrow morning at the latest.
