Web Forms :: Uploading And Downloading Files From A List Type?

Mar 2, 2011

I am using an ASP.NET FileUpload to upload files to the server. How to upload it to the rootfolder of my project. 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.

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#.

Uploading To And Downloading Files From The Server?

Nov 20, 2010

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?

Web Forms :: Downloading An Xml File In Web App Is Of Type .aspx?

Oct 14, 2010

Ive created a Web App where it is possible to download an xml file from the server to the client. It works just fine except that the Save Dialog recognizes the file being dowloaded as of type .aspx and the name of the file as being the name of the page I' on. The page is called Download.aspx and it contains a button that when clicked executes the following code:

[Code]....

The save dialog appears and says:

Name: Download.aspx

Type: ASP.NET Server Page, 1,16KB

From: 127.0.0.1

If I download the file and open it it contains the correct Xml file content and nothing else, so it is working correctly. It just annoys me that it appears to the user that he is downloading the aspx site (and it shows up as such in windows explorer as well) rather than the xml file which is the actual content.

Web Forms :: Time Out Downloading Large Files?

Jun 1, 2010

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);..................

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">

Downloading Files In MVC Web Applications?

May 6, 2010

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.

C# - Downloading Multiple Files Using Ihttphandler?

Oct 20, 2010

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)

Web Forms :: Uploading Multiple Files In 1.1?

Sep 23, 2010

I am trying to make a web application which copies the existing functionality of a windows forms application using Visual Studio 2003. This windows application takes multiple (I am talking at least 30) text files and joins them together into one text file which can then be feed into a Mainframe system in the correct format. I have written web applications before that uploads images and pdfs but the key thing is it was always only one or two files at a time, so this was easy to do with the HTML fileupload control.

What I want to do is to be able to open a directory on the local computer and either automatically, or give the user the chance to multi select (I dont think this is possible) all of the 30 or so files they wish to upload. Once its been uploaded I can do the processing to join the files and create my new one etc. All the examples I have seen on the web, you have to select the files one by one to add to a list box and then they can all be uploaded but this wont be acceptable to my users...

Web Forms :: Uploading Files From One Site To Another?

Aug 24, 2010

I need to upload files from one site to another and I thought about using the WebClient class and FileUpload method from the System.Net namespace. I read the MSDN documentation and it seems an easy task to achieve but something is going on wrong. For now, I am only testing with the following simple code to upload a file to a test web server in our office which uses HTTP port 8080 instead of 80:

[Code]....

The code above issues the following exception: "The remote server returned an error: (404) No Found." I have made sure that both paths are correct.

Also, does the UploadFile method saves the file physically in the hard disk (I suppose so) or does it load it into the server's memory?

How To Create A HttpHandler For Downloading Files From The Server

Sep 22, 2010

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?
