Hello IG,
It's not so much a security issue as it is the following: A master file contains all the records, once an item from that master file has been selected it is "copied" to a new "temp" file for use in the program. Once the temp file has out lived its use the items in the master file are able to be selected again. The issue is how do I make the items selected from the master file remain un-selectable until the temp file has been removed? Also the files in use are only a few KB each. Thanks for the ideas and suggestions.
