CDaoDatabase::Create
To create a new Microsoft Jet (.MDB) database, call this member function after you construct a CDaoDatabase object.
virtual void Create(
LPCTSTR lpszName,
LPCTSTR lpszLocale = dbLangGeneral,
int dwOptions = 0
);
Parameters
lpszName
A string expression that is the name of the database file that you are creating. It can be the full path and filename, such as "C:\\MYDB.MDB". You must supply a name. If you do not supply a filename extension, .MDB is appended. If your network supports the uniform naming convention (UNC), you can also specify a network path, such as "\\\\MYSERVER\\MYSHARE\\MYDIR\\MYDB". Only Microsoft Jet (.MDB) database files can be created using this member function. (Double backslashes are required in string literals because "\" is the C++ escape character.)lpszLocale
A string expression used to specify collating order for creating the database. The default value is dbLangGeneral. Possible values are:dbLangGeneral English, German, French, Portuguese, Italian, and Modern Spanish

dwOptions
An integer that indicates one or more options. Possible values are:dbEncrypt Create an encrypted database.
dbVersion10 Create a database with Microsoft Jet database version 1.0.
dbVersion11 Create a database with Microsoft Jet database version 1.1.
dbVersion20 Create a database with Microsoft Jet database version 2.0.
dbVersion30 Create a database with Microsoft Jet database version 3.0.
If you omit the encryption constant, an unencrypted database is created. You can specify only one version constant. If you omit a version constant, a database that uses the Microsoft Jet database version 3.0 is created.
警告
If a database is not encrypted, it is possible, even if you implement user/password security, to directly read the binary disk file that constitutes the database.
Remarks
Create creates the database file and the underlying DAO database object and initializes the C++ object. The object is appended to the associated workspace's Databases collection. The database object is in an open state; do not call Open after Create.
备注
With Create, you can create only Microsoft Jet (.MDB) databases. You cannot create ISAM databases or ODBC databases.
