Imports System.IO
Imports System.Data.SqlClient
Public Class Form1
Dim str As String = "PATH OF DATABASE"
Dim scon As SqlConnection
Dim scom As SqlCommand
Dim sql As String
Dim sda As SqlDataAdapter
Dim sds As DataSet
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
scon = New SqlConnection(str)
sql = "select *from info"
scom = New SqlCommand(sql, scon)
sda = New SqlDataAdapter(scom)
sds = New DataSet
sda.Fill(sds)
DataGridView1.DataSource = sds.Tables(0)
End Sub
Private Sub DataGridView1_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEndEdit
Dim i As Integer
i = DataGridView1.CurrentRow.Index
scon = New SqlConnection(str)
sql = "update info set sname='" & DataGridView1.Item(1, i).Value & "',mob=" & DataGridView1.Item(2, i).Value & " where id=" & DataGridView1.Item(0, i).Value & ""
scom = New SqlCommand(sql, scon)
scon.Open()
scom.ExecuteNonQuery()
scon.Close()
End Sub
End Class
