以下黄色代码的功能怎么实现不了呢？一直报错

If e.Table.Current IsNot Nothing Then
    Dim dr As DataRow = e.Table.Current.DataRow
    Dim wz As Integer = Tables("ShuDaShuJuZiDian").FindRow(dr)
    If wz >=0 Then
        Tables("ShuDaShuJuZiDian").Position = wz
    End If
    If Tables("ShuDaShuJuZiDian").current.Isnull("审核") = True
        e.form.strips("主菜单").Items("Edit").items("ShenHe").Enabled = False
        e.form.strips("主菜单").Items("Edit").items("QuXiaoShenHe").Enabled = True
   Else
       
        e.form.strips("主菜单").Items("Edit").items("ShenHe").Enabled = True
        e.form.strips("主菜单").Items("Edit").items("QuXiaoShenHe").Enabled = False
    End If
End If

以下生成菜单的代码，在AfterLoad事件中生成

Dim mnu As Winform.Strip
Dim itm As WinForm.StripItem
mnu = e.Form.Strips.Add("主菜单",StripTypeEnum.MainMenu)
mnu.Items.Add("File","文件(&F)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("Edit","编辑(&E)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("ShenHeShenPi","审核审批(&S)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("homepage","首页(&H)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("pageup","上页(&A)","",StripItemTypeEnum.MenuItem)

mnu.Items.Add("lastpage","末页(&L)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("MuLuShu","打开目录(&M)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("GengXing","更新(&G)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("Option","选项(&O)","",StripItemTypeEnum.MenuItem)
mnu.Items.Add("Help","帮助(&H)","",StripItemTypeEnum.MenuItem)
\'在主菜单右侧增加一个按钮

mnu.Items("Home").DisplayText = False
mnu.Items("Home").DockToRight = True \'靠右停放
\'为文件菜单增加项目

\'为常用项目增加快捷键
itm.Items("New").ShortcutKeys = Keys.Control Or Keys.N
itm.Items("Open").ShortcutKeys = Keys.Control Or Keys.O
itm.Items("Save").ShortcutKeys = Keys.Control Or Keys.S
itm = mnu.Items("Edit")
itm.Items.Add("AddNew","新增","new.ico",StripItemTypeEnum.MenuItem)
itm.Items.Add("ShanChu","删除","Open.ico",StripItemTypeEnum.MenuItem)
