数据库中存有图片,三维模型等信息,我在asp实现下载这些信息功能,通过在一个页面(如A.aspx)中"下载"按钮,把参数传到另一个页面中(如DownLoad3DFiles.aspx)进行处理,现在实现了下载功能,可是下载完后这个DownLoad3DFiles.aspx页面却没有消失~~
现在问题是:::怎样才能在下载完的同时DownLoad3DFiles.aspx也消失?或者DownLoad3DFiles.aspx根本不出现~~

在A.aspx中传到DownLoad3DFiles.aspx的程序如下:
Response.Write(String.Format("<script language=JavaScript>window.open('DownLoad3DFiles.aspx?graphcode={0}&number={1}&Producted_3Dgraph={2}','', " + " 'height=330,width=560,status=no,location=no,toolbar=no,directories=no,menubar=no')</script>", graphcode, number_3D, Producted_3Dgraph));


非常感谢各位!!!!!

DownLoad3DFiles.aspx页面下载数据的代码贴出来瞧瞧...

感谢回帖!希望能得到您的帮助!
程序如下:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using database;
using System.Data.SqlClient;

public partial class ProductManagement_DownLoad3DFiles : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
int number= Convert .ToInt32 ( Request.QueryString["number"]);
string GraphCode = Request.QueryString["GraphCode"];
string Producted_3Dgraph = Request.QueryString["Producted_3Dgraph"];

if (GraphCode != string.Empty)
{
//this.Response.ContentType = "image/jpeg";
string strSQL;

strSQL = "select GraphBody, FileType,FileName from " + Producted_3Dgraph + " where graphcode= '" + GraphCode + "'" +
" and Number ='" + number + "'";
//strSQL += " UNION ALL select ProductJTGraph from app_private_producted where graphcode= '" + GraphCode + "'";
SqlDataReader pic_reader = database.Database.ReturnDataReader(strSQL);
while (pic_reader.Read())
{
if (pic_reader["GraphBody"] != null && pic_reader["GraphBody"].ToString() != string.Empty)
{
Response.Clear();
Response.ContentType = pic_reader["FileType"].ToString();
Response.AddHeader("content-disposition", "attachment;filename = GraphCode+ " + pic_reader["FileName"].ToString());
Response.Buffer = true;
Response.BinaryWrite((byte[])pic_reader["GraphBody"]);

}

}
}

}

掉了这两句吧

...

Response.Flush();

Response.Close();

还有

注意Response.ContentType = "application/octet-stream";必须这样设置

先看看,帖子不错.

谢谢你的回帖!
我在以下代码加上那几句后下载完后弹出的页面还是没有消失~请你再帮忙看看~
strSQL = "select "+ Query_type +" from " + Producted + " where GraphCode= '" + GraphCode + "'";
SqlDataReader pic_reader = database.Database.ReturnDataReader(strSQL);
while (pic_reader.Read())
{
if (pic_reader[Query_type] != null && pic_reader[Query_type].ToString() != string.Empty)
{
string filename = GraphCode;
if(Query_type=="TwoDimBlueprint") filename += "test.dwg";
else if(Query_type=="Product2DimGraph") filename += "test.jpeg";
else if (Query_type == "ProductJTGraph") filename += "test.jt";
Response.Clear();
//==========================================
Response.ContentType = "application/octet-stream";

Response.AddHeader("content-disposition", "attachment;filename="+filename);
Response.Buffer = true;
Response.BinaryWrite((byte[])pic_reader[Query_type]);
//==========================================
Response.Flush();

Response.Close();
}
}

有可能跟你打开窗口的方式有关吧，你试试直接在下载按钮事件里
Response.Redirect('DownLoad3DFiles.aspx?.....);
