Has anyone had expeience with C++ and writing fail-safe code? My naive approach is to copy object values to a folder on the hard drive, so that if the program crashes, I can have key values saved. However, I am finding upon bringup, that naively creating the C++ objects all over again is wiping the crucial saved data. I am curious if anyone has done this type of coding? I would like to get in touch. Thanks Randall _______________________________________________ There are two ways to look at the problem, first is persistence, i.e. copy your objects to disk as objects. Google for C++ object persistence and you will probably find something. In Java your objects need to be created as serializable, I do not know what the equivalent in C++ is. Second is to map an object to a database, so if you change and data elements they are automatically updated in the database. There are many libraries out there for doing both approaches. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
