Hi all, The concept presented below involves loading the DB into memory. My question has to do with the impact on the users computer, if the memory is reserved for this function. I'm using Delphi 5. The database could be as much as 200 MB. The users could be using Win 2000, XP, or Vista. 1. Does Delphi 5 handle large TStringLists adequately? 2. Will the DB take away from RAM or will Delphi 5 page it out to disk? 3. Are the any quirks in the operating systems that I should know about?
Many thanks for any details on these issue, Gerry B.
