Hi,
Thank you for reply.
I would like to ask some other questions, very sorry for my "troublesism".

1. I try to use VB as GUI service and VFP as middle tier and data store in my project. Should I SET PATH everytime once I initialite my business class?

2. Do I need to OPEN DATABASE everytime?

3. I would like to pass some parameter in CREATEOBJECT() to my class. How could I know the parameter passed in corrected (e.g. PATH) instead of using another method or property to detect it once intialised?

Thank you.
