以下是引用片段:

其代码如下:
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        '在此处放置初始化页的用户代码
        If Not Page.IsPostBack Then
            Dim cnn As New Sql2000DB
            Dim tmpda As New DataTable
            Dim strQr As String
            '如果当前这个学生已经有了选题信息 则显示否则的话  显示学生信息
            tmpda = cnn.GetData("select * from Send_StudentBY,Send_Student,Send_TeacherTM where Send_StudentBY.tmid=Send_TeacherTM.tmid and Send_StudentBY.xsid=Send_Student.id and  Send_Student.id='" & Session("id") & "'")
            If tmpda.Rows.Count > 0 Then
                Me.txtXm.Text = tmpda.Rows(0)("ID")
                Me.txtBykt.Text = tmpda.Rows(0)("xm")
                Me.txtZddf.Text = tmpda.Rows(0)("bj")
                Me.txtPjdf.Text = tmpda.Rows(0)("tmmc")
                strQr = tmpda.Rows(0)("qrbz")
            Else
                tmpda = cnn.GetData("select * from Send_Student where Send_Student.id='" & Session("id") & "'")
                Me.txtXm.Text = tmpda.Rows(0)("ID")
                Me.txtBykt.Text = tmpda.Rows(0)("xm")
                Me.txtZddf.Text = tmpda.Rows(0)("bj")
            End If
            '显示所有可以选择的毕业设计题目列表
            Me.DataGrid1.DataSource = cnn.GetData("select * from Send_TeacherTM,Send_Teacher where Send_TeacherTM.jsh=Send_Teacher.id and Send_TeacherTM.qrbz<>'教师确认'")
            Me.DataGrid1.DataBind()
            If strQr = "教师确认" Then
                Me.DataGrid1.Columns(4).Visible = False
            End If
        End If
    End Sub
