i don´t think my client lends me his clipper application, he just ask me for modifying his tables and delete the registers. But the two ways i have to make it posible it´s by using visual fox pro 6.0 or visual studio.net 2003. But i jus use visual fox. The matter is with the *.ntx file. I jus want to modify the tables without damage their structures. But you tell me that my client can regenerate the *.ntx file with the project indexes. That will be OK because I can tell my cliente to do that. Just tell me how to modify the tables, save changes and later my client regenerate the index files by his own. Thanks
