首先，我建了个窗体，放了一个按扭控件，把打开连接EXECL的代码都放在该按扭的click事件里了，你可以根据需要改动。
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _
"Data Source=E:\myexl.xls;" _
"Extended Properties=Excel 8.0;"
’这里面，E：\myexl.xls换成你自己的excel文件完整路径
Dim objConn As New OleDbConnection(sConnectionString)
objConn.Open()
MsgBox("成功打开连接") ’这句我用来测试能不能连接的，
’下面将建立查询命令
Dim objCmdSelect As New OleDbCommand("SELECT * FROM [11$] where 姓名='李三'", objConn)
'11j是我测试用的sheet名，你换成你自己的，注意格式
'程序默认Excel表的第一行内容为字段名，你换成你自己的内容，并建
'立查询条件
'下面将根据查询条件打开连接。
Dim objAdapter1 As New OleDbDataAdapter()
objAdapter1.SelectCommand = objCmdSelect
'下面将打开的数据放在dataset中
Dim objDataset1 As New DataSet()
objAdapter1.Fill(objDataset1, "XLData")
’下面将数据传给DataGrid1控件
DataGrid1.DataSource = objDataset1.Tables(0).DefaultView
' Clean up objects.
objConn.Close()
End Sub
当然能，把你不分页的程序贴出来，我给你修改嘛。
主要就是利用rs.PageSize等实现，在你程序的下面语句：
rs.open sqlc,conn,1,1
之后，添加下面的代码可以控制显示的记录范围：
rs.PageSize = 10 'pagesize属性指定了每页要显示的记录条数
rs.AbsolutePage = Page '把页码赋给absolutepage属性从而知当前页的首条记录号
上的PAGE是调用是带过来的参数，没有参数时指定为1，表示显示第一页。
你可以这样,如果你用 dataGridview 时不是也要查询表嘛,
我们用datatable/dataset 保存你查询的结果,
然后就可以一条条显示,记录住当前显示的row(行)
eg:你的查询保存 datatable1
第一条时,
我们就来个 dim dtrow as datarow=datatable.rows(0)
textbox1.text=dtrow.item("字段名")'
...
都是如此
当然也是可能绑定的
CurrencyManager 用于管理显示的行数
textbox.DataBindings.add("属性",data,"字段")

有两个表order(orderid,ordername,totalprice), orderdetail(orderid,productid,productname,price) 已经建立一对多
关联(orderid). 用VB.NET建立一个窗体, 用于主表和明细表的数据录入及更新.
在窗体上增加两个sqldataadapter,分别选择order和orderdetail表, 并生成数据集,在DATASET中建立关联(orderid) 主表中:ORDERID,ORDERNAME 绑定在两个TEXTBOX文本框中,用于接受用户的输入,totalprice接受明细表中price
的汇总值.
明细表绑定到一个DATAGRID控件, datasource:dsorder; datamember:order.orderorderdetail建立的关联名称
问题: 在主表中新增一个记录,用户录入orderid和ordername后,进入明细表的录入,用户录入productid, productname, price后,提示 “明细orderID列不允许空值，要更正该值吗？” 是什么原因?
用于连接主表的明细orderID如果输入跟主表一样的orderID时提示“ForeignKeyconstraint 要求在交叉表中存在子键值。要更正该值吗？”
只有录入主表中的orderid和ordername后, 先更新主表数据源,才可以编辑更新明细表,这是为什么? 请问,有没有其他更好的方法, 实现主表和明细表的新增记录同时更新呢? 谢谢关照！ 网友：方宇 回复：
