Web Forms :: Viewing And Downloading Existing Files
Jan 21, 2010
I want to view the existing files in a directory which is "~/Images". Now the code below works fine and it shows the files (with its name and other details) in this directory very well in a data grid. The name is a hyperlink, but when I click on it, it tries to view the file in "~" (i.e current working directory) instead of "~/Images" and therefore reports the server error as - "file not found".
Also, how to implement if I want the save as option when I click on the file, so that I could save it directory locally instead of viewing it in browser?
VB Code-
Imports System.IO
Partial Class uploaddoc
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dirInfo As New DirectoryInfo(Server.MapPath("~Images"))
articleList.DataSource = dirInfo.GetFiles("*.gif")
articleList.DataBind()
End Sub
End Class
HTML (ASP.NET) Code -
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="uploaddoc.aspx.vb" Inherits="uploaddoc" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I used this sample to work around the issue we were having with large files. [URL] Unfortunately, when I attempt to download large files of 30MBs or more, the download times out and the user gets a partial download. It doesn't seem to be a consistant percentage of the download either. I attempted to download a 50MB file and got to 33MB. When trying a 30MB file, I downloaded 24MB.Below is my code.
if (File.Exists(strFilePath))
{
fileName = System.IO.Path.GetFileName(strFilePath);
Response.Clear();
system.IO.Stream iStream = null;
byte[] buffer = new Byte[10000];
int length;
long dataToRead;
try
{
iStream = new System.IO.FileStream(strFilePath, System.IO.FileMode.Open,
System.IO.FileAccess.Read, System.IO.FileShare.Read);
dataToRead = iStream.Length;
//FileInfo file = new FileInfo(strFilePath);
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Length", iStream.Length.ToString());
Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName.Replace(" ", string.Empty));
while (dataToRead > 0)
{
if (Response.IsClientConnected)
{
length = iStream.Read(buffer, 0, 10000);..................

I want to add the files to a collection or list of files to be shown on the webpage in the form of gridview. Each file should have a link to itself in the list So that it could be downloaded by the click-if desired. The gridview will also have a delete column so that I can delete any of the corresponding file-as desired.

I have some images and text files that are used by web pages that are available to anonymous users and therefore those files can be viewed directly from a browser.
Is there a way to avoid this and allow the files to be viewed only when a page in the web site calls it ?

I'm new to this forum, infact this is the first forum i hav ever joined. I need some help urgently as i'm reaching the deadline of my project.I created an asp.net website, where administrator will upload files to SQL database which is connected to the webpage. From the web page there will be a download link to download those uploaded files. I have been successful in uploading files to the database. But nothing is striking in my mind regarding how to download files directly from database using asp.net C#.

I'm working on a project that requires the ability to let a user download a pdf from a static location on the server. I'm reading the instructions from this website, it's an old post and I notice they specify in an update that Microsoft's MVC framework has long since included and Action Result that allows the same functionality they discuss thus rendering it obsolete, I've looked a bit online but haven't been able to find any resources that discuss this built-in functionality.

I am working on some project where I am needed to allow users to upload files, but only in pdf and .doc format. Now I know how to let users upload files, but I do not know how to check whether an uploading files is pdf and .doc or not. How could I know that? And how could I know the size of each file, for the file should be no greater than 3 MB?
Also, I have alloted a separate folder for the files that are uploaded by users. I have one page that displays the links to download the files in that folder. I needed to know how could I keep the track of the folder, for the files get uploaded every time? Or in other words, how could my 'downloads page' know about the files in that folder and create links for each file in that folder for the download? Also, if I create a link of a file for downloading purposes, will the file be downloaded when one clicks the link?

I'm working on a reporting script which runs a number of reports (pdf) on button click. The reports are created on the web server then I'd like the user to be given the option to download the files. I have worked out the script for downloading one file from the server. But I'm not sure how to download multiple files? (there will probably be about 50)
After I run one report I redirect the user to a http handler script.
Response.Redirect("Download.ashx?ReportName=" + "WeeklySummary.pdf");
public class Download : IHttpHandler {
public void ProcessRequest(HttpContext context)
{
[Code]....

I created a HttpHandler for downloading files from the server. It seems it is not handling anything...I put a breakpoint in the ProcessRequest, it never goes there.
public class DownloadHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
//download stuff and break point
}
}
It never stops there, as mentioned. I also registered it in the web.config.
<add verb="*" path="????" type="DownloadHandler" />
I am not sure about the path part of that entry. What do I have to enter there? I am downloading txt files, but the URL does not contain the filename, I somehow have to pass it to the handler. How would I do this? Session maybe?

I am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL.

I'm experiencing some strange behavior when using generic handler for downloading files from database to client using my web application.
Basically, everything works just fine in Chrome. But, when using Firefox the PDF documents don't get displayed entirely. Once downloaded to hard drive, they work fine. Excel documents get corrupted and users need to repair them in order to use them.
Below is the generic handler I use to download selected documents:
vb.net Code:
Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
Dim documentID As Int32
If Not context.Request.QueryString("documentID") Is Nothing Then
documentID = Convert.ToInt32(context.Request.QueryString("documentID"))

For a church website I'm managing, there is a need to place audio files (sermons) on the website. There will be two categories of audio files; one will be a sample size of the audio file, around 5 minutes in length. The other will be the full-length of the sermon (30-50 +/- minutes).
I have decided the best setup would be to place the audio files on the server. I would then store the audio information, as well as the path to the audio file, in a database. I had thought about placing the audio files in the database as a BLOB, but it seemed inefficient. My concern, is with tools like Mozillza plug-in "Download Helper" , it is so easy to simply grab the media files off the server. This would not be a big deal, except we want to sell the full-length audio files. I am running ASP.NET 3.5 on IIS 7.

I have this following code for bringing page attachments to the user:
[code]...
The problem is that all supported files works properly (jpg, gif, png, pdf, doc, etc), but .docx files, when downloaded, are corrupted and they need to be fixed by Office in order to be opened.
At first I didn't know if the problem was at uncompressing the zip file that contained the .docx, so instead of putting the output file only in the response, I saved it first, and the file opened successfully, so I know the problem should be at response writing.
