Assuming this is an untrappable error, you could check for the existance of the cdx with file(), then use low-level file functions to check and reset the byte(s) that indicate that the dbf has an associated cdx for those that are missing. Then reindex them.

>I had my application written using vfp5a. However, some of index are often out of synch, so I had to delete the index (CDX) files and do a indexing again. However, when I delete it then index it again in my code, it is working okay, However, when I manually delete it using window explorer, it will give me error when my program open the file and report of invalid *.idx file.
