Re: question... no field names?

texte = >If you >delete a column from the .hdr file, the column in the table is deleted >(please verify this!!!!!).No, the column is not deleted in the .db file when you delete a field name (and the tab character next to it) from the .hdr file. Instead, you'll just end up having some of your field names in the wrong columns.The rule to remember when messing with .hdr files is that you can add a tab then a new field name to the end of the list of field names in the .hdr file, but you cannot remove any field names (and associated tab characters) and expect that the corresponding field data will be removed from the .db file -- because it will not be removed.In other words, never delete a field name from a .hdr file unless you *also* delete that field manually from every record in the .db file. That's the rule I use to insure that I do not screw up my db formats ...
