If the backup bit is set for a database, during HotSync it is saved on the desktop as a PDB file. An app on the desktop can read that PDB file. Also, if you write a conduit for the application, the conduit can read records from the database on the handheld (and on the desktop) during the sync. > Joe wrote, "...and the person who receives the PDB has the > same app on his handheld, and if the version number of your > PDB is higher than the version number of their PDB...". > I am not clear about the "version number".

The version number I was referring to is a sequential number that is stored in a database to indicate which revision of the database it is. (Many databases just use 0.) This revision number can be used to manage multiple versions of a database. You can retrieve this number with DmDatabaseInfo() and you can set it when you build the database or change it with DmSetDatabaseInfo(). I believe one of the Epstein's published the arcane rules by which the OS decides which databases will overwrite which other database, so you might want to search the archives. The simplest rule is that a higher version numbered db will overwrite a lower numbered db. ...
