CeFindFirstDatabaseEx (CEDB) (Compact 2013)

3/26/2014

This function opens an enumeration context for all databases in a database volume.

Syntax

HANDLE CeFindFirstDatabaseEx( 
  PCEGUID pceguid, 
  DWORD dwDbaseType
);

Parameters

• pceguid
  [in] Pointer to the CEGUID that contains the globally unique identifierof a mounted database volume. If pceguid points to the system GUID value, the object store is used as the database volume. If pceguid is NULL or set to an invalid GUID, all mounted database volumes are searched.

• dwDbaseType
  [in] Type identifier of the databases to enumerate. If this parameter is set to zero, all databases are enumerated in the volume. For Windows Embedded Compact-based devices, a volume is the object store or a mounted database volume.

Return Value

A handle to an enumeration context indicates success. INVALID_HANDLE_VALUE indicates failure. To get extended error information, call GetLastError. GetLastError may return ERROR_OUTOFMEMORY if no memory is available to allocate an enumeration context handle.

Remarks

This function returns only the handle to a enumeration context. To begin enumerating databases, call the CeFindNextDatabaseEx (CEDB) function. When an application is finished with the handle to the enumeration context, use the CloseHandle function to release the resources associated with the enumeration context. To find the databases of the desired type, specify the enumeration context handle in multiple calls to CeFindNextDatabaseEx (CEDB).

You can create a system GUID using the CREATE_SYSTEMGUID macro, and you can create an invalid GUID using the CREATE_INVALIDGUID macro.
