ADO.NET ODBC Connection

An instance of the OdbcConnection class in .NET Framework is supported the ODBC Data Provider. The OdbcConnection instance takes Connection String as argument and pass the value to the Constructor statement. When the connection is established , SQL Commands may be executed, with the help of the Connection Object, to retrieve or manipulate data in the database.

Once the Database activities over , Connection should be closed and release the resources . The Close() method in SqlConnection class is used to close the Database Connection. The Close method rolls back any pending transactions and releases the Connection from the Database connected by the ODBC Data Provider.

Imports System.Data.Odbc
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim cnn As OdbcConnection
        connetionString = "Driver={Microsoft Access Driver (*.mdb)};DBQ=yourdatabasename.mdb;"
        cnn = New OdbcConnection(connetionString)
            MsgBox("Connection Open ! ")
        Catch ex As Exception
            MsgBox("Can not open connection ! ")
