Which option is used to connect database with VB net?

There are various database connectivity options that can be used to connect a database with Visual Basic for Net. One popular option is the ADO.NET connection string, which uses the System.Data namespace and the IADODB interface to manage connections between a data source and an application using .NET objects (such as Tables, Views, DataSet etc).

A database connection is required to be able to work with a VB net program. A connection object is a way of manipulating a database connection. A connect string is the textual representation of the connection object.

The connect string is used to specify the particulars of the connection. The following are some of the key items that are included in the connect string:

• Database name
• User name
• Password
• Server address
• Database type
• Database connection options
• Maximum allowed connection number
• Preferred data compression
• Use default tables

The connection object can be created using the following code snippet:

Dim Conn As New SqlConnection("Data Source=server name;Initial Catalog=database name;User ID=user name;Password=password;"

& _

"Connection Timeout=30;" & vbCrLf)

Once the connection object is created, it can be used to access the database. The following code snippet shows how to connect to the database and issue a query:

Conn.Open()

Once the connection is established, the data can be accessed using the following code snippet:

Dim Data As String

Data = Conn.Execute("SELECT * FROM tableName")

# Note: while executing this statement, the system will display a message stating that the operation is successful or failed.

The connection object can be closed using the following code snippet:

Conn.Close()

There are a number of ways in which the connection object can be used. One way is to specify the connection options when creating the connection object. This can be done by setting the Connection Timeout and Connection Size properties. The following code snippet shows how to do this:

Conn.Connectionoptions = connOptions

Another way to use the connection object is to use the Open option. This can be used to connect to the server and issue a query. The following code snippet shows how to do this:

Conn.Open("data source=localhost;persist security Info=True;initial catalog=AdventureWorks;integrated security=True")

The connection object can also be used to create a Connection object. This can be done by using the New() function. The following code snippet shows how to do this:

Conn = New SqlConnection("Data Source=localhost;Persist Security Info=True;Initial Catalog=AdventureWorks;Integrated Security=True")

10. Finally, the connection object can be closed using the Close() function. The following code snippet shows how to do this:

Conn.Close()

The connect string is used to specify the particulars of the connection.
