I'm checking to see if a UPC field was changed to a duplicate record. I thought that the easiest way to do this would be to check the OLDVAL() of the field in the Valid method of the textbox, and if it changed, use INDEXSEEK to see if the new value was already in the table. However, OLDVAL() is returning the numeric equivalent of the character field, which is not exactly ideal. Is this a VFP bug/misfeature, or do I just need to go downstairs and load up on coffee?
Thanks. _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
