Connections to existing databases are added to the Workspace by using a
right mouse-button context sensitive menu option 'Add Connection...' which
invokes the Add/Modify Database connection dialog box. They can be
modified later by selecting the 'Edit...' option from the menu.
The Add Connection dialog box show below is show when the 'Add
Connection...' menu option is selected from the Database connection editor,
and the identical Modify Connection dialog box when the 'Edit' menu is
selected.
For convenience, a unique Connection name is created automatically. This
can be changed to give a more meaningful description of the connection, if
required.
Enter the database file to be used as a Data Source, or locate using the
Browse button. The following data source file types are supported:
• MS-Access Files (*.mdb)
• MS-Excel Files (*.xls)
• Text Files (*.txt, *.csv)
• FoxPro Files (*.dbf)
• Data Source Names (*.dsn)
A Data Source Name file stores information about a database connection in a
file. See Creating a Data Source Name file for more information.
Note: Connecting to CSV or Text files is slightly different from an actual
Database connection. Only the 'Directory' that contains the required files
should be supplied as a Data Source - if a file is selected, the connection will
fail. The actual file to be used is specified later when configuring the
Recordset. For example, if a collection of text or csv files are contained in the
directory C:\Text then a valid connection 'Data Source' is "C:\Text\".
Note: Connections to CSV or Text files using the Provider installed with ADO
version 2.0 are read only. Records can not be added or amended. To create a
read/write connection to a CSV or Text file see chapter 12, Creating a Read/
Write connection to CSV/Text file.
Note: Connections to Excel files using the Provider installed with ADO version
2.0 are read only. Records can not be added or amended. To create a read/
write connection to an Excel file see chapter 12, Creating a Read/Write
connection to an Excel file.
