'将数据库DB.mdb放在Debug目录下:
Imports System.Data.OleDb
Public Class Form1
    Dim MyConnection As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Application.StartupPath & "\DB.mdb")
    Dim MyCommand As OleDbCommand
    Dim dbset As New DataSet
    Dim dataA As OleDbDataAdapter
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        MyConnection.Open()
        MyCommand = New OleDbCommand("Select * from BOOK ", MyConnection)
        dataA = New OleDbDataAdapter(MyCommand)
        dataA.Fill(dbset, "BOOK")
        DataGridView1.DataSource = dbset.Tables("BOOK")
        MyConnection.Close()
    End Sub
 end class

#2


嗯,可以用代码,就是上面这位写的。也可以自己拖个datagridview。然后配置它的datasource.这是根据配置界面可以完成。。

#3


Using cn As New SqlConnection("")
    cn.Open()
    Dim ds As New DataSet()
    Dim cmd As New SqlCommand("select * from Tb", cn)
    Dim da As New SqlDataAdapter(cmd)
    Dim builder As New SqlCommandBuilder(da)
    da.Fill(ds, "Test")
    Me.dataGridView1.DataSource = ds.Tables(0).DefaultView
End Using

#4


大家都给了你比较完整的代码,其实简单的就是分为二个部分,一部分将数据读取出来放到一个dataTable中,第二部分就是直接绑定至gridview上。

学习中。。。。。。。。

#9


            SqlCommand cmd = conn.CreateCommand();
            cmd.CommandText = "Select * from film_detail order by filmName ";
            SqlDataReader dr = cmd.ExecuteReader();
            DataTable dt = new DataTable();
            dt.Load(dr);
            gridview.DataSource =  dt;
            gridview.DataBind();
            dr.Close();
            conn.Close();
             这个一定好使,我刚用完.

VB.NET中的代码: 试试吧!

Imports system.data
imports System.Data.SqlClient
Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
   dim con as new sqlconnection("server=(local);uid=sa,pwd=sa;database=pubs")
   dim cad as new sqldataadapter("select * from authors",con)
   dim bset as new dataset
   cad.fill(bset,"authors")
   me.datagridview1.datasource=bset.Tables("authors").DefaultView
   bset.Dispose()
   cad.Dispose()
End Sub

end Class
