哪位帮我看看下面的代码啊？datagridview 批量更新问题。
Imports System.DataImports System.Data.OleDb
Module Module1
Public DatabasePath = Apppath & "\1.mdb;"
Dim ConnStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & DatabasePath & ""
Dim Conn As OleDbConnection
'如果要从数据库里取出数据显示在Datagridview上，那么如此使用：
'Dim SQLStr As String = "select * from xxx"
'DataGridView1.DataSource = FillDataSet(SQLStr).Tables(0)
#Region "填充返回dataset"
Public Function FillDataSet(ByVal SQLStr As String) As DataSet
Try
Conn = New OleDbConnection(ConnStr)
Conn.Open()
Dim da As OleDbDataAdapter = New OleDbDataAdapter(SQLStr, Conn)
Dim ds As DataSet = New DataSet
da.Fill(ds)
Return ds
Catch ex As Exception
MsgBox(ex.Message.ToString, MsgBoxStyle.Information, "提示")
FillDataSet = Nothing
Finally
Conn.Close()
End Try
End Function
#End Region
#Region "批量更新dataset"
Public Function Fillupdata(ByVal SQLStr As String) As DataSet
Try
Conn = New OleDbConnection(ConnStr)
Conn.Open()
Dim da As OleDbDataAdapter = New OleDbDataAdapter(SQLStr, Conn)
Dim ds As DataSet = New DataSet
'da.Fill(ds)
da.Update(ds)
Return ds
Catch ex As Exception
MsgBox(ex.Message.ToString, MsgBoxStyle.Information, "提示")
Fillupdata = Nothing
Finally
Conn.Close()
End Try
End Function
#End Region
我在form1上有一个 datagridview用来显示数据库中表"库存"的内容。
Dim SQLStr As String = "select * from 库存"
DataGridView1.DataSource = FillDataSet(SQLStr).Tables(0)
然后我更改了datagrivew中的数据，请问怎么批量更新到access数据库中啊？
上面的 批量更新dataset
Fillupdata代码正确吗？在form1的button中怎么调用啊？ --------------------编程问答-------------------- Dim ds As New DataSet()
Dim sda As SqlDataAdapter
Dim scb As New SqlCommandBuilder(sda)
sda.Update(ds)
Me.dataGridView1.DataSource = ds.Tables(0) --------------------编程问答--------------------

Fillupdata代码正确吗？在form1的button中怎么调用啊？ --------------------编程问答-------------------- 使用OleDbCommandBuilder批量更新,需要数据库有主键字段，搜下网上很多的。
Dim MyCommandBuilder As New OleDbCommandBuilder
MyCommandBuilder = New OleDbCommandBuilder(da)
da.Update(ds, "tablename") --------------------编程问答-------------------- 沒有用過DatagridView，一直用FlexGridC1
因為，我一直用的是vb.net 2003

能帮我写个详细的吗？根据我上面的信息。谢谢 --------------------编程问答-------------------- 在线等待啊！
