求救高人
我的代码运行哪儿有错啊？请指正，谢谢！
代码如下：
Imports System.Data.SqlClient

Public Class Webtus1
Inherits System.Web.UI.Page

Dim StuTable As Object



Function CreateDataSet(ByVal strSQL As String, ByVal FileName As String, ByVal TableName As String) As DataSet
Dim conn As New SqlConnection()
Dim cmd As New SqlCommand()

conn.ConnectionString = " Data Source=RFTU-58C014ED1B;Initial Catalog=sqldatatjj;Integrated Security=True"
conn.Open()
cmd.Connection = conn
cmd.CommandText = strSQL
Dim objAdpt As New SqlDataAdapter(cmd)

Dim DS As New DataSet()
objAdpt.Fill(DS, TableName) '表名
CreateDataSet = DS
conn.Close()
End Function


Sub DisplayDS(ByVal DS As DataSet)
Dim i, j As Integer
Dim TabRow As TableRow = New TableRow()
Dim TabCell As TableCell
For i = 0 To DS.Tables("sqldataxss").Columns.Count - 1
TabCell = New TableCell()
TabCell.Text = DS.Tables("sqldataxss").Columns(i).ToString 't
TabRow.Cells.Add(TabCell)
Next '

StuTable.Visible = True
StuTable.Rows.Add(TabRow)
For i = 0 To DS.Tables("sqldataxss").Rows.Count - 1
TabRow = New TableRow()
For j = 0 To DS.Tables("sqldataxss").Columns.Count - 1
TabCell = New TableCell()
If DS.Tables("sqldataxss").Rows(i).IsNull(j) Then
TabCell.Text = "空值"
Else
TabCell.Text = DS.Tables("sqldataxss").Rows(i)(j).ToString
End If

TabRow.Cells.Add(TabCell)
Next
StuTable.Rows.Add(TabRow)
Next
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Protected Sub BtnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs) Handles BtnSubmit.Click
Dim DS As New DataSet()
DS = CreateDataSet("select * from sqldataxss", "sqldatatjj.mdf", "sqldataxss")
Dim DTable As DataTable = DS.Tables(0)
Dim TabRow As DataRow = DTable.NewRow()
If TxtNo.Text <> "学号" Then
TabRow("学号") = TxtNo.Text
End If
If TxtName.Text <> "姓名" Then
TabRow("姓名") = TxtName.Text
End If
If TextBox1.Text <> "出生年月" Then
TabRow("出生年月") = TextBox1.Text
End If

晕，vb.....你换成sql看看在SQLServer上能不能运行成功，如果可以就换成存储过程，然后vb调用存储过程
