Hi folks,

The new version of SpiderBasic is available on your online account and brings some nice new features, and many bug fixes !

- Database library, based on sqlite (client side)
- Added #PB_LocalStorage support for CreateFile(), OpenFile() and ReadFile() to easily create persistent files
- Added #PB_HTTP_Put, #PB_HTTP_Patch, #PB_HTTP_Delete support for HttpRequest()
- Added ExportFileMemory() to return the full file content as a memory buffer
- Added 'End' keyword support to quit an application

Have fun and don't hesitate to report anything wrong so we can have a great release !

C'est bon à savoir !

Autre info intéressante, pour conserver une base de données vous pouvez utiliser les nouvelles fonctions dédiées aux fichiers

Et Fred (l'auteur de PureBasic et SpiderBasic) complète l'information

To understand how the database works: it's always created in memory and stay in memory. You have to use the regular file functions to persist it. You can persist any files now, not just database.

Pour comprendre comment les bases de données fonctionnent, il faut savoir qu'elles sont toujours créées en mémoire et restent en mémoire. Il faut utiliser les fonctions dédiées aux fichiers pour rendre les bases de données persistantes.
vous pouvez rendre persistant n'importe quel fichier, pas uniquement les bases de données.
