File Download Via External Link - How To Implement
Oct 18, 2010
I have a web application which consists of many aspx pages ... one of them shows a grid with rows that can be exported to a file via button click. This works fine. Now I want to have that feature which allows a user to access an external link to this page (or another) and to export to a file and download. I dont need any information on the page, just the file download. How could I do this also including security features like encryption?
First,I uploaded a file in a external server and got a url from that server.Now i want to download that uploaded file from the external server through that url which i got from that server through asp.net and c#.I wrote a c# code to download that file, but during that process i got an exception "Exception of type 'System.OutOfMemoryException' was thrown".The following is the c# code which i wrote to download:
I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request.
There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service.
I have some information I am pulling from my db into a table. Can anyone direct me to a tutorial that shows how to dynamically create a file and allow a user to download that file with the table contents. All this must be dynamic.
i was just wondering how one would approach creating a link that would be active for 24 hours for a user... ie i have in the db a time of confirmation and then wanted to make a download active for them for 24 hours and deactivate it post then.
On daily basis, I am saving a file in my PC. The name of the file is same but with different date including date. What I required to just there should be a gridview with hyperlink button(Download File) columns like this:
ReportDate Extent Status HostedOn HostedBy DownloadFile 24/Mar/2010 0700 Hrs Daily Not Added -- DownloadFile 23/Mar/2010 0700 Hrs Daily Added 23/Mar/2010 James DownloadFile 22/Mar/2010 2100 Hrs Daily Added 22/Mar/2010 Mike DownloadFile 22/Mar/2010 0700 Hrs Daily Added 22/Mar/2010 James
When user click "DownloadFile" button then it should go to particular folder in server and download file. he task is very important and urgent for me.
mov is a quicktime file, my server has the mimetype: video/quicktime .......... but as I read, this code forces the save as download box which is exactly what i want :) now, here's the catch, i the file I am fetching is NOT on the physical path... it is on a completely different server:Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click Response.Clear() Response.ContentType = "x-msdownload" Response.AppendHeader("Content-Disposition", ("attachment; filename=mydownload.mov")) Response.TransmitFile("http://myOTHERserver.com/files/mydownload.mov") Response.End() End Sub
Obviously this doesn't work since TransmitFile requires that the file be on your physical path, so how do i do this? Someone said you must use the stream method. Do you have any sample code I could try? I've tried the HTTPStreamReader object but it's giving me issues, so I would love to find out if there is anyway this might work. Now here's some more important information: this are HUGE video files.. we are creating a downloads page... written in asp.net -- so you create an account using the .net membership class, then you select the file you want, go through a form where you enter your billing info and then after you pay a certain fee (this is already implemented), you go to your "downlaods" area in your account... there you have access to the files......... the reason i'm doing this is because i want to hide the download link, which will be something likehttp://myOTHERserver.com/2340987sdfkjhalsdlkjh23 ... (something really crazy)....... we don't want people seeing this on the status bar (Therefore hiding the download link is ESSENTIAL)........ the files are a good 500MB each approximately; so i would love to hear all of your suggestions as to making the streamreader work for me and how long would it take for the streamreader to READ the file........
I am trying to create a link that is distributed via eMail. This link will direct the user to a View inside my MVC2 application. I will need to pass 2 parameters with this link. Background: The eMail is an invitation. The user will click the link inside the eMail to RSVP for a meeting. When the link is clicked I want the user to be directed to a certain controller action/view. The parameters will be an eMail address (string) and a meeting ID (int).
The controller action will use the parameters to process logic that determines what the view will display. An example using the following would be perfect:
I'm trying to build a link to an external website using some properties of my model class in my view page, e.g. I want it to render as something like -[URL]where post-id would be pulled from the model (I'm using a strongly typed view model here - I can't use ViewData as there's a list of items being pulled back all of which need seperate links).I tried doing < a href="<% model.PermaLink(); %>">, where PermaLink is just some string, however the value doesn't get picked up.If I try < a href="<%= model.PermaLink %>">, I get an error - CS1502: The best overloaded method match for 'System.IO.TextWriter.Write(char)' has some invalid argumentsIs there any way to do this? I tried adding the runat="server" attribute, however this just linked to my local site and controller/model actions.
am trying to get one of the webforms in my application to link to another website, outside of my application. I can get the page to load as a new webpage in my browser easily but I need to keep my masterpage in view.
I want to add some information, like an adress, in the header of an collapsible panel. I want to add a link to google maps to it in the header. But if i click on the Link, the panel collapses/expands but the click on the link will be ignored. I guess the click on the panel overrides the link :/
I am trying to implement a website that was developed on a test server and make it go live. I am running into an issue with a function within the DB that decrypts a password. Here is the function
I am using Web Expression and Access database to build an aspx page.I am displaying records using listview Tiled option and DataPager is enabled also which is creating multiple pages.
I'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?
I'm customizing a NopCommerce store, and am using a gridview to display and sort the products. All that works well. I like how the external pager (user control) works with the gridview, with one exception -- it uses the hyperlink control, so I lost viewstate, which I need to retain for both the search page and to retain the gridview sort options. Based on the page selected (from the pager control), I query the database and rebind the gridview. So, I switched the user control to use LinkButtons instead of Hyperlinks. This is the sample code for one of the buttons:
[Code]....
I set a breakpoint inside the lbCommandClick method, but it never gets hit. Reading other posts tells me that I would have to add the dynamic controls in the OnLoad method, but since this all happens based on other data on the page (say search results), I don't think I can do it onLoad. However, the link buttons do work to cause a postback, and my viewstate is saved correctly. The only problem is that I do not know which button was clicked. I could check Request.Params["__EVENTTARGET"] onLoad, but that is kind of a hack -- I'd much rather be able to set the event handler in the user control and use the CommandArgument property. But, what I have tried so far fails.
Especially one that would allow me to set the EventHandler in the User Control? (e.g. OnlbCommand="PagerLBPageChange" )
I want people to download files, EXE & DOCs from my website but I want to track the download, therefore I don't want them to now the real url so they won't be able to go there directly to download
