CeSetDatabaseInfoEx (CEDB) (Windows CE 5.0)
This function sets various database parameters, including the name, type, sort-order descriptions, and compression of the database. This function is obsolete. Applications should call CeSetDatabaseInfoEx2 (CEDB) instead.
This function does not work with EDB databases. For more information on EDB, see EDB Functions.
A RAPI version of this function exists called CeSetDatabaseInfoEx (RAPI).
BOOL CeSetDatabaseInfoEx( PCEGUID pceguid,CEOID oidDbase,CEDBASEINFO* pNewInfo);
Parameters
- pceguid
[in] Pointer to the CEGUID that contains the globally unique identifier of a mounted database volume or of the object store. Use CREATE_SYSTEMGUID to obtain the GUID of the object store. - oidDbase
[in] Object identifier of the database for which parameters are to be set. - pNewInfo
[in] Pointer to a CEDBASEINFO structure that contains new parameter information for the database. The wNumRecords member of the structure is not used.
Return Values
TRUE indicates success. FALSE indicates failure. To get extended error information, call GetLastError. The following table lists possible values for GetLastError.
| Value | Description |
|---|---|
| ERROR_INVALID_PARAMETER | Indicates that a parameter was invalid. |
| ERROR_DISK_FULL | Indicates that the object store or mounted volume is full and any size changes required could not be accommodated. Changing sort orders can minimally change the size of the stored records. |
| ERROR_SHARING_VIOLATION | Indicates that the CeSetDatabaseInfoEx function tried to remove a sort order that is being used by a currently open database. For Windows 3.0 and later, this indicates that CeSetDatabaseInfoEx was called on an open database. |
Remarks
Use CeSetDatabaseInfoEx to change the database parameters passed in while creating the database. Changing the sort order or compression of a database is a very expensive operation, possibly taking a few minutes. Before calling this function, warn the user that this is a lengthy process. You cannot change the sort order if someone else has this file open.
For Windows CE 3.0 and later, the sort orders of a database cannot be changed while a handle to that database remains open.
Changing the compression of a database affects only new and modified records.
If you attempt to change the information for an existing database and pass the CEDB_VALIDNAME flag in the dwFlags member of the CEDBASEINFO structure, you will receive an error stating that there is an existing database with that name. If you do not want to change the database name, you should not set the CEDB_VALIDNAME flag. Only the flags for the parameters that are changing should be set. For parameters that are not changing, you should not set the corresponding CEDB_VALID* flag.
Requirements
OS Versions: Windows CE 2.10 and later.
