The two ways I have tried it are:
1/ same box, same program, 2 accounts (via winxp fast user switching)... The 1st one opens the program, the second one opens the program and tries to insert a new adress. No constant polling of the database is done etc??
2/ 2 computers, common share on windows server... 1 person opens the program on 1 client, 2nd person on 2nd client, 2nd tries to insert an adress...
Both setups give 'database is locked'.
:S
Sorry for the long delay (no internet for 4 days -> arrgh).

Hi,Sqlite minor versions should have compatible database formats, so if you're having crashes, there's probably a problem somewhere else.
1/ I am currently using 2.8.13 and I wanted to upgrade it to 2.8.15... Now when I do that, my program crashes when I try to open (sqlite_open) the database on the following function:
rc = sqliteBtreeFactory(db, zFilename, 0, MAX_PAGES, &db->aDb[0].pBt);
Is that "normal" behaviour (for instance: no binary compatibilities between 2.8.x versions?). Of course that would be better then to immediatly upgrade to 3.0 if i have to convert all the databases ofcourse. But then the same question stays... Is there compatibility between those versions? (again I mean: just update the source & I can still work on the same databases without doing something special).
2/ I use wxSQLite to access databases. When 1 person has my program open (just open, that means not doing anything). Then another person opens a program from a different location, and access the same databases. He can read it without a problem, but he can't do any insert/update/delete ? (so I think he can acquire readlock, but no writelock). [using 2.8.13]. Is this a feature or a bug? (as far as I understood, sqlite locks the database file when it is needed, but not all the time?).
Could someone answer those questions, I would be very gratefull.
BTW, if I am unclear somewhere, please request more information!

For the other question, how are the two people accessing the database file? NFS, samba, or just different terminals on the same box? This
can make a difference, as locking on network filesystems has varying levels of success(although it is never reccomended).
