CEDBASEINFO (Windows Embedded CE 6.0)

  • Artigo

1/6/2010

This structure contains information about a database object. This structure is used by the CeSetDatabaseInfo and CeCreateDatabaseExfunctions.

Syntax

typedef struct {
  DWORD dwFlags;
  WCHAR szDbaseName[CEDB_MAXDBASENAMELEN];
  DWORD dwDbaseType;
  WORD wNumRecords;
  WORD wNumSortOrder;
  DWORD dwSize;
  FILETIME ftLastModified;
  SORTORDERSPEC rgSortSpecs[CEDB_MAXSORTORDER];
} CEDBASEINFO;

Members

  • dwFlags
    This member is one or a combination of the following flags.

    Flag Value Description

    CEDB_VALIDNAME

    0x0001

    The szDbaseName member is valid and should be used.

    CEDB_VALIDTYPE

    0x0002

    The dwDbaseType member is valid and should be used.

    CEDB_VALIDSORTSPEC

    0x0004

    The rgSortSpecs member is valid and should be used.

    CEDB_VALIDMODTIME

    0x0008

    The ftLastModified member is valid and should be used.

    CEDB_VALIDDBFLAGS

    0x0010

    This flag should be used in combination with the following flag to set the compression state of the database.

    CEDB_VALIDCREATE

    0x0017

    (CEDB_VALIDNAME | CEDB_VALIDTYPE | CEDB_VALIDSORTSPEC | CEDB_VALIDDBFLAGS)

    CEDB_NOCOMPRESS

    0x00010000

    The database is not compressed. If this flag is used with CeSetDatabaseInfoEx, new or modified records in a compressed database are uncompressed. If this flag is used with CeCreateDatabaseEx, the database is not compressed.

    By default, all databases are compressed. If you want to change the compression, it should be done at creation time.
  • szDbaseName
    Null-terminated string that contains the name of the database. The string can have up to 32 characters, including the terminating null character. This member must be set when used for CeCreateDatabaseEx.
  • dwDbaseType
    Specifies the type identifier for the database.
  • wNumRecords
    Returns the number of records in the database.
  • wNumSortOrder
    Number of sort orders active in the database. Up to four sort orders can be active at a time.
  • dwSize
    Specifies, in bytes, the size of the database.
  • ftLastModified
    Returns the last time this database was modified.
  • rgSortSpecs
    Array containing the sort order descriptions. Only the first n array members are valid, where n is the value specified by the wNumSortOrder member. If no sort orders are specified for CeCreateDatabaseEx or when CEDB_VALIDSORTSPEC is not specified, then a default sort order is assigned to the database.

Remarks

For Windows Embedded CE versions 2.10 and later, dwFlags has additional meaning, but is still compatible with previous versions. The high-order word of dwFlagsspecifies additional database properties.
