Part 6: Windows Mobile application 189 CEDB The CEDB format is a database format that can be used on the mobile devices (Pocket PC). A CEDB database corresponds to a ".CDB" file. A CEDB database can contain several data files (also called "tables"). Two types of CEDB databases are available: • the standard CEDB databases , that correspond to the databases found by default on the mobile device. These databases contain the following data files: "Tasks", "Contacts", "Appointments", ... • the other CEDB databases (called custom databases), that correspond to the Access databases (".MDB" file) previously exported from a PC. Remark: When an Access database (".MDB" file) is copied onto a mobile device (via the file explorer), this database is automatically changed into a CEDB database (".CDB" file). A CEDB database can be handled: • from a WINDEV Mobile application. • from a WINDEV application. These operations are performed by the cdbXXX functions of WLanguage. Remark Caution : From Windows Mobile 5 onwards, a standard database (tasks, contacts, appointments, etc.) can no longer be accessed from a Window application (and therefore from a standard WINDEV application). CEDB databases can be accessed from the PC, from the simulator, from the mobile device. Standard databases can be accessed from the mobile device only. Remark Caution : The structure of CEDB databases is not adapted to the process of large data amount. Therefore, we recommend that you use HFSQL databases. Furthermore, HFSQL allows you to benefit from all features available in WINDEV Mobile (RAD, file link, ...). Remark During the test (in simulation mode) of a WINDEV Mobile application that handles a CEDB database, the database used is found on Pocket PC . AS/400 This database format is accessible via a Native Connector (also know as Native Access) by Windows Mobile applications. To use this Native Connector, a module is required in addition to WINDEV Mobile. Contact PC SOFT Sales Department for more details.
