Anyway Could you tell me which book should i take a look for the first time? Thank Anyway,would you like tell me where should i pick up that book"Database Programming Make Easy"? hi i am already design the code using 2005 for insert data in the table , but when i am again run that program then all the previous value of the table will delete and again newly entry value are store in table my code: Imports System. Ole Db Public Class Form1 Dim con As New Ole Db Connection("Provider=Microsoft.
I started in from beginner,but I don't where should i begin. ...adding record in table updating retrieving and deleting..in advance... Startup Path & "\raghu1stdb.mdb") 'Dim da As Ole Db Data Adapter Dim da As New Ole Db Data Adapter("select * from table1", con) 'Dim x As String = "select *from table1" ' da = New Ole Db Data Adapter(x, con) Dim ds As New Data Set, dt As New Data Table, dr As Data Row Dim i As Integer Dim bm As Binding Manager Base : Dim cb As Ole Db Command Builder Dim cm As Ole Db Command Private Sub Form1_Load(By Val sender As System. Select Command = New Ole Db Command(x, con) da = New Ole Db Data Adapter(x, con) ds = New Data Set da.
Applications communicate with a database, firstly, to retrieve the data stored there and present it in a user-friendly way, and secondly, to update the database by inserting, modifying and deleting data. An application accesses data either through a dataset or a data reader.
Various components of the data provider retrieve data for the application and update data.
NET generally provides us with all the tools we require.
The best way normally to start learning how to make such systems is to learn basic CRUD with database. We assume that you can create a ms access database. You then specify the path to the database in the connection string in our code. Ole Db Public Class Form1 'GLOBAL DECLARATIONS Dim con String As String = "Provider=Microsoft. OLEDB.4.0; Data Source=C:/Users/Sedan/Documents/Data Bases/people DB.mdb;" Dim con As Ole Db Connection = New Ole Db Connection(con String) Dim cmd As Ole Db Command Dim adapter As Ole Db Data Adapter Dim dt As Data Table = New Data Table() Private Sub Form1_Load(sender As Object, e As Event Args) Handles My Base.
When a connection is established with the database, the data adapter creates a dataset and stores data in it. Click Dim connection As Sql Connection = New sqlconnection() connection.
After the data is retrieved and stored in a dataset, the connection with the database is closed. The dataset works as a virtual database containing tables, rows, and columns. Connection String = "Data Source=KABIR-DESKTOP; _ Initial Catalog=test DB; Integrated Security=True" connection. Tables(0) End Sub End Class When the above code is executed and run using Start button available at the Microsoft Visual Studio tool bar, it will show the following window: Clicking the Fill button displays the table on the data grid view control: We have discussed that the Data Set components like Data Table, Data Column and Data Row allow us to create tables, columns and rows, respectively.
