Before you begin:

The object store is the permanently mounted RAM-based storage area that contains the built-in file system, the system registry, and property databases.

This class is subclassed from the base RAPI class. Some members of it are implemented through collections. That unfortunately makes it unusable under Visual FoxPro versions 6 and older.

Solutions based on this class:

enumerating mounted database volumes and databases in the Object Store

reading the Contacts Database

creating new database and adding records to it

My comment:

MSDN:"Databases provide storage, access, and sorting of property-set records.

The Windows CE database model is that of a small, flat structure, optimized for small, efficient storage. As such, the Windows CE database APIs do not correspond to the Win32 database APIs.

Data operations are transactioned within the object store or a database volume, which protects against data loss. If a Windows CE–based device loses power (reset or suspend/resume, where the RAM is refreshed) during a data transaction, Windows CE reverts all partial database operations to the last known good state. "

	Does not work with vfp7. Uses Try/Catch code GDIPlus.Prg uses vfp8 Createobject("collection") which is unsupported in vfp7.
