Doesn't DmOpenDatabase (and about all of the other DmMgr functions) usually generate a fatal alert when given an invalid cardNo and dbID? One alternative is to use DmGetDatabase() to iterate through all of the databases on the device and stop if you find one with a matching dbID. __________________________________ Do you Yahoo!? Yahoo!
