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:
double dlsize=0;
string Url = "http://www.sample.com/download.zip"; \File Size: 75MB
int lastindex = Url.LastIndexOf("/");
string TempUrlName = Url.Substring(lastindex + 1, Url.Length - (lastindex + 1));[code]....

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.

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

here's the code so far:
[Code]....
[Code]....
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:
Controller action / View name: RSVPmeeting
Parameter: AttendeeEMail (string)
Parameter: MeetingID (int)

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.

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'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" )
