How Do I Find Data Column And Get Data From That Selected Column

 Try



            'Dim Cmd As OleDb.OleDbCommand
            Dim Con As OleDb.OleDbConnection
            Dim Sql As String = Nothing
            'Dim Reader As OleDb.OleDbDataReader
            Dim ds As New DataSet()
            Dim adapter As New OleDbDataAdapter()


            Con = New OleDb.OleDbConnection(DBpath)

            Sql = "SELECT Users.* from Users where LoginID=" & "'" & TextBox1.Text & "'"

            'Cmd = New OleDb.OleDbCommand(Sql, Con)
            adapter.SelectCommand = New OleDbCommand(Sql, Con)
            Con.Open()

            adapter.Fill(ds, "Users")
            Dim item As DataTable = ds.Tables(0)
            DataGridView1.DataSource = ds.Tables("Users")

            Console.WriteLine("Table name: {0}", item.TableName)
            Console.WriteLine("Its columns are:")

            
            For Each col As DataColumn In item.Columns
                If col.ColumnName.Substring(col.ColumnName.Length - 3) = "Upd" Then
-----HERE I GOT TO FIND THE FIELDS I WANT BUT NEED TO PICK the value of that field_______
                    'If row(col.ColumnName).Item.ToString = "yes" Then
                    
                        Console.WriteLine("{0}" & vbTab & "{1}", col.ColumnName, col.DataType)                    End If
                End If
            Next
           






            Con.Close()






        Catch ex As Exception
            MsgBox(ex.Message)
        End Try


    End Sub
