主题：下面这些代码有错吗？

I f e.sender.S electedIndex = 0 Then

Dim tb As WinForm.Table = e.Form.Controls("Table1")
Dim lvw As WinForm.ListView = e.Form.Controls("ListView1")
Dim txtb As WinForm.TextBox = e.Form.Controls("TextBox1")
txtb.Text=lvw.Rows(0)("工程名称")
Dim cmd As  SQLCommand
''cmd.C
cmd.CommandText="s elect 序号,项目名称,内容 from {工程概况} where {工程概况}.工程名称='"& txtb.Text &"'"
Tables("具体项目指标_Table1").Fill(cmd.CommandText,"外部数据sql2008",True)
End If

想让“具体项目指标_Table1”sqlquerry的表显示显示select语句的结果
