Send Feedback

This function is used to remove properties from a database.

This function does not work with CEDB databases. For more information about CEDB, see CEDB Reference.

BOOL CeRemoveDatabaseProps(PCEGUIDpGuid,CEOIDoidDb,DWORDcProps,CEPROPID*prgProps);

Parameters

  • pGuid
    [in] The CEGUID of the mounted volume in which the database identified by the oidDb parameter resides. You can mount a volume by using the CeMountDbVolEx (EDB) function.
  • oidDb
    [in] The OID of the database from which to remove the property IDs. This database must exist in the volume specified by the pGuid parameter. This OID must have been generated by the CeCreateDatabaseWithProps (EDB) function.
  • cProps
    [in] The number of property IDs in the prgProps array.
  • prgProps
    [in] The array of property IDs to remove from the database.

Return Values

TRUE indicates success. FALSE indicates failure. To get extended error information, call GetLastError. The following table lists possible values returned by GetLastError:

Return Value Description
ERROR_INVALID_PARAMETER Indicates one of the following:
  • pGuid is NULL.
  • oidDb is NULL.
  • cProps is 0.
  • prgProps is NULL.
  • One of the property IDs in the prgProps array has an invalid CEVT_xxx data type.
ERROR_NOT_FOUND Indicates one of the following:
  • The volume specified by pGuid does not exist.
  • The database specified by oidDb does not exist in the specified volume.
  • One of the property IDs specified in the prgProps array does not exist in the database.
ERROR_ACCESS_DENIED Indicates that the property is part of an active sort order.
ERROR_SHARING_VIOLATION Indicates that another thread currently has the database open.

Remarks

At some point, a client may decide that there are properties in a database that are no longer used. When this occurs, the client can use this function to remove those properties and clean up the database, potentially resulting in a volume size reduction.

This function succeeds only if the database is not open and the property is not part of an active sort order.

Properties are added to a database by using the CeAddDatabaseProps (EDB) function.

Requirements

OS Versions: Windows CE 5.0 and later.
Header: Windbase.h.
Link Library: Coredll.lib.
