Error: Invalid Index Descriptor
Question:
How come I get the error "Invalid Index Descriptor"
when opening my FoxPro 2.5 table?
Answer:
This error occurs when the production index (.CDX) associated
the table has an index tag which has an expression which the BDE
cannot evaluate. The solution is to delete the tag using FoxPro
create an eqivalent index that the BDE can understand.
For example, FoxPro has a function called ALLTRIM() which the BDE
cannot evaluate. A index that causes a problem might be created
as following in FOXPRO:
INDEX ON ALLTRIM(Field) TAG mytag
Instead, the following index could be created instead:
INDEX ON LTRIM(RTRIM(Field)) TAG mytag
