May 6, 2010I'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.

Nov 20, 2010I 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 :: Time Out Downloading Large Files?
Jun 1, 2010I 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];

How To Create A HttpHandler For Downloading Files From The Server
Sep 22, 2010I 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?

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.

View 4 RepliesVS 2012 - Generic Handlers For Downloading Files

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.

Prevent Unauthorized Downloading Of Audio Files From A Server?
Mar 2, 2010For 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.

Httpresponse - Why Are .docx Files Being Corrupted When Downloading From A Webpage
Mar 19, 2010I 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.
