  • Article

1/6/2010

This structure contains information about a database object. This structure is used when calling the CeCreateDatabaseWithProps (EDB), the CeSetDatabaseInfoEx (EDB), and the CeGetDBInformationByHandle (EDB) functions.

Syntax

typedef struct CEDBASEINFOEX {
  WORD wVersion;
  WORD wNumSortOrder;
  DWORD dwFlags;
  WCHAR szDbaseName[CEDB_MAXDBASENAMELEN]; 
  DWORD dwDbaseType;
  DWORD dwNumRecords;
  DWORD dwSize;
  FILETIME ftLastModified; 
  SORTORDERSPECEX rgSortSpecs[CEDB_MAXSORTORDER];
} CEDBASEINFOEX;

Members

  • wVersion
    Version of this structure. Must be set to 2.
  • wNumSortOrder
    Number of sort orders that can be active in the database. Up to 16 sort orders can be active at a time.

  • dwFlags
    One or a combination of the following flags:

    • CEDB_VALIDDBFLAGS
    • CEDB_VALIDNAME
    • CEDB_NOCOMPRESS
    • CEDB_VALIDSORTSPEC
    • CEDB_VALIDTYPE
  • szDbaseName
    Name of the database. The string can have up to CEDB_MAXDBASENAMELEN characters, including the terminating null character. This member must be set when used with the CeCreateDatabaseWithProps (EDB) function.
  • dwDbaseType
    Type identifier for the database.
  • dwNumRecords
    Number of records in the database.
  • dwSize
    Not used by EDB.
  • ftLastModified
    Not used by EDB.
  • rgSortSpecs
    Array containing sort order descriptions. Only the first n array members are valid, where n is the value specified by the wNumSortOrder member.

Remarks

The following are the differences between this structure and the CEDB equivalent:

  • In EDB, when no sort orders are specified for the CeCreateDatabaseWithProps (EDB) function or when CEDB_VALIDSORTSPEC is not specified, a default sort order is not assigned to the database. CEDB assigns a default sort order.
  • EDB does not support the following dwFlags member values that CEDB supports:
    • CEDB_SYSTEMDB
    • CEDB_VALIDMODTIME
  • EDB does not use the following fields that are used by CEDB:
    • dwSize
    • ftLastModified

Requirements

Header windbase.h
Library coredll.lib
Windows Embedded CE Windows CE 5.0 and later
