例子：
以下是父页的Html代码
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="main.aspx.vb" Inherits="zero.main"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>

SetCookie("SendSql",sql);
var url="child.aspx";

}
function SetCookie(name, value)
{
document.cookie = name + "=" + value;
}
</script>
</HEAD>
<body MS_POSITIONING="GridLayout" >
<form id="Form1" method="post" runat="server">
<INPUT id="Hidden1" type="hidden"

</HTML>
child 页[子页]

</HTML>
.vb文件
If Not IsPostBack Then
'Response.Write(Request.Form("Hidden1"))
Dim cookie As HttpCookie = Request.Cookies("SendSql")
If Not cookie Is Nothing Then
Response.Write(cookie.Value)
End If
End If
2。是思归大哥介绍的方法
在父页中加入一个非runat=server的form表单，用来提交隐藏控件的值到子页
<form method="post" target="_blank" id="form2">
<input type=hidden name="query">
</form>
<script language="javascript">
function searchvalue()
{
var sql="select * from companyjob";
document.all.form2.query.value=sql;
document.all.form2.action="child.aspx";
document.all.form2.submit();
}
</script>
子页的后台代码中 (.vb)
在Page_Load事件中写
Response.Write(Request.Form("query"))
