TO RUN:
From the File menu, choose Open Project, and select the
VISDATA.MAK file, which is located in the \SAMPLES\VISDATA 
subdirectory of the main Visual Basic directory.

If you want to open a local database, you simply need to choose
the type of database, and a File Open dialog box will be 
displayed with the file type set to the requested data file type.

If you choose ODBC on the Open Database submenu, you will then
see the Open DataBase form.  Since you probably have no 
servers entered, you will need to enter a name for an existing 
SQL server on your network.  If you already know the user ID and 
password, you can add them as well.  The Database name is optional.  
Once you have entered this data, choose OK, and you should be
able to log on to the server.  You may get some more dialogs in 
the process.  Answer any questions you can and ask the SQL 
administrator for help if you run into problems or don't know some 
of the parameters.

Once a database is open, double-clicking a table name
will open the table in the selected form type and recordset type.
Use the Query Builder to create dynasets with selected data from
one or more tables at a time.

The table-type Recordset is always updatable.  The dynaset-type
Recordset will be updatable in most cases except on ODBC with 
no unique index, certain multiple table joins, and other SQL Select 
statements such as count(*), max(), and so forth.  The snapshot-type 
Recordset is never updatable.
