Thanks for replied Ed,
I'm using Windows98, so I think PNP driver for AGP card won't be a problem since I'll pick Diamond or Intel's AGP card (which I do not remember the type).
I hope this can help me out of C000005 Err.
I use VFP6.0 to built an accounting system for 14 different company, and none of them built in a same code, can you imagine how frustrate I am with this Err problem......, all of this problem never occured when I'm still using VFP 5.
