AFAIK you can not create a table with varchar field with older VFPOLEDB driver. You must download and install the lastes OLE DB driver for VFP, because before VFP9 there is no such type of field.

Also, the unique field obviously speeds up scans alot because of the cdx index, but will vb.net automatically create this index? I need to use a table that wont require a driver that does not come with a clean install of win2k, so I figured a dbf would be the fastest.
