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 narray members are valid, where nis the value specified by the wNumSortOrdermember.

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 dwFlagsmember values that CEDB supports:

    • CEDB_SYSTEMDB

    • CEDB_VALIDMODTIME

  • EDB does not use the following fields that are used by CEDB:

    • dwSize

    • ftLastModified
