Hi All, don't know where this message belongs so I'll start here. I am gradually migrating an old DOS Fox app to a C# Winforms one, most of the functionality is now in the new one except for adding new claims ( it's a liquidation app and there are very few new claims - think 2 a year ) so my client doen't want me to rewrite the "add new claims" function as it's does hideously complicated validation. What they have asked me to do, is ; periodically compare the DOS tables with the new SQL ones - and if any new records exist - pull them into SQL Server. Before I go down the wrong road - has anyone here done this sort of thing ? should I use SQL server or a C# prog to periodically check the tables ?
