hi this small exmple to bulid database

i am saeed alhosni from Oman.
let's start.
create database with Microsoft access "People.mdb"
with password =hand
put the database in Debug folder in new vb project(the next one)
create table name it"LifePeople" with two cluoms one "hi" second "hii"
open visual studio 2005.
start new project
add new Module(name it "Connection_String"
write this code

vb.net Code:

Imports System.Data.Odbc
Imports System.Data.OleDb
Imports System
Imports System.Data
Module Connection_String
   
    Public MyPath As String = Application.StartupPath & "\People.mdb"
    Public MyPassword = "hand"
 
    Public ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & MyPath & ";Jet OLEDB:Database Password=" & MyPassword
    Public str_sqa, TableName, msg, CardNumber, UserName As String
 
 
    Public VoucherString As String
 
    
End Module

add new Class "db_operation"
write this code

vb.net Code:

Imports System
Imports System.Data

    'OleDbDataAdapter and OleDbConnection, to select rows from an Access database.

    End Function
 
End Class

add to the form
-2 textbox
-one datagridview

add this code to the form1 load

vb.net Code:

dim intCtrCard as integer
Try
            Dim get_Data As New db_operation
            str_sqa = "SELECT * From LifePeople"
            TableName = "LifePeople"
            MyTableCard = get_Data.PopulateDataset(str_sqa, TableName).Tables(0)
            intRecordCountCard = MyTableCard.Rows.Count
            Me.datagridview1.DataSource = MyTableCard            
Me.textbox1.Text = MyTableCard.Rows(intCtrCard)(0).ToString      
Me.textbox2.Text = MyTableCard.Rows(intCtrCard)(1).ToString      
 
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try

Welcome to the forums. :wave:

Do you have a question?

no but i want to benefit everyone else.
this code is working very well.
i get all lot of useful thing from this forum.
this is a gift.

There is a codebank section for stuff like this.

Moved to the CodeBank
