It would help also. I also suggest to implement artificial tests like constantly emulating user actions in your program. Once it helped me to find the cause of the same corruption error. It would be some dev-only menu item that activates a loop constantly reading randomly and writing randomly until specially interrupted. While the program reads and writes you check PRAGMA integrity_check; from time to time and stop if result shows corruption. If you can't reproduce the problem on your machine you can send specially prepared version to the user and ask him to perform the similar actions Max Vlasov, maxerist.net _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
