邮件已经发生，请查收。记得给分哈
你选中一条数据的时候把这条数据的ID也给取出来、点击修改把你去到的ID跟页面上三个TEXT框中的值同时转到后台进行修改、删除也是把你选中这行的ID传到SQL里
引用 Microsoft ActiveX Data Objects 2.8 Library
或者加入microsoft ado data control
定义数据库连接
Dim Cnn As New ADODB.Connection
定义操作记录
Dim Res As New ADODB.Recordset
开始使用
If Res.State = 1 Then Res.Close
Res.CursorLocation = adUseClient
Res.Open "SELECT * From 发票表", Cnn, adOpenDynamic, adLockReadOnly
删除用res.Delete
添加用res.AddNew
res.Fields("序号") = Trim(Res.Fields("序号"))
...
res.Update
更新用Res.Update "序号", 111
列：
'写入产品信息
Sub WriteFP()
'On Error Resume Next
Dim SyBaseRes As New ADODB.Recordset
PB.value = 0
Res.Open "SELECT Count(*) From ICSaleEntry INNER JOIN t_Item ON ICSaleEntry.FItemID = t_Item.FItemID INNER JOIN t_MeasureUnit ON ICSaleEntry.FUnitID = t_MeasureUnit.FMeasureUnitID", SQLServer, adOpenDynamic, adLockReadOnly
Text2.Text = "当前共 " Val(Res.Fields(0)) "条数据"
PB.Max = Val(Res.Fields(0))
If Res.State = 1 Then Res.Close
Res.Open "SELECT ICSaleEntry.FDetailID AS 序号,ICSaleEntry.FInterID AS 物料编号, t_Item.FName AS 产品名称,ICSaleEntry.FAuxPrice AS 单价, ICSaleEntry.FAuxQty AS 数量,ICSaleEntry.FAmount AS 原币, ICSaleEntry.FStdAmount AS 本币,t_MeasureUnit.FName AS 单位 FROM ICSaleEntry INNER JOIN t_Item ON ICSaleEntry.FItemID = t_Item.FItemID INNER JOIN t_MeasureUnit ON ICSaleEntry.FUnitID = t_MeasureUnit.FMeasureUnitID", SQLServer, adOpenDynamic, adLockReadOnly
Do While Not Res.EOF
If SyBaseRes.State = 1 Then SyBaseRes.Close
SyBaseRes.Open "select * from 物料表 where 序号='" Res.Fields("序号") "'", Cnn, adOpenDynamic, adLockOptimistic
If SyBaseRes.EOF Then
Text2.Text = Text2.Text + vbCrLf + "正在添加: " Trim(Res.Fields("序号"))

SyBaseRes.Update "单位", Trim(Res.Fields("单位"))
SyBaseRes.Update "数据库名", Trim(Text1.Text)
End If
PB.value = PB.value + 1
Res.MoveNext
DoEvents
Loop

Set SyBaseRes = Nothing
End Sub
网络希望不要用ACCESS用ASA（就是sybase那个太强了）
sQueryString是SQL（增删查改）语句
public
Boolean
ExecSQL(string
sQueryString)
{
SqlConnection
con
=
new
SqlConnection(ConfigurationManager.AppSettings["conStr"]);
con.Open();
SqlCommand
dbCommand
=
new
SqlCommand(sQueryString,
con);
try
{
dbCommand.ExecuteNonQuery();
con.Close();
}
catch
{
con.Close();
return
false;
}
return
true;
}
}
建立一个类，明自己取，然后调用就是了
例如：
类
BC=NEW
类（）；
STRING
ist="INSERT
INTO
XX(1,2,3)VALUES(A,B,C)";
BC.ExecSQL（ist）;
就可以了
一般是将access数据库绑定到datagridview中，要添加数据只需要datagridview1.Item(3, 0).Value=XXX这种就行了，删除修改同理。保存到access是你已经有了一个access表吧？不然字段都要新建的。如果要保存到数据库的话就调用sql语句链接数据库了，我找个以前的代码 Dim OleDbConn As OleDbConnection = New OleDbConnection("provider=microsoft.jet.oledb.4.0;data source=保存信息\保存信息.mdb;persist security info=false")
OleDbConn.Open()
Dim adapter As New OleDbCommand("insert into 受检单位信息(检测日期,测量器具) values(#" + DateTimePicker1.Value + "#,'" + 测量器具 + "')", OleDbConn)
adapter.ExecuteNonQuery()
