I am very fairly new to web programming. I am attempting to download an excel from an ASP.net website. IT does not need authentication, however I am unable to debug the URL as firebug would just not how me the request URL. Searched high and low.
Website: [URL]
Actions: I click "Summary Download" button to download the excel.
I have no idea where the onClick() goes.
I'd like to create a asp.net download page. I receive the file from a dataservice as a byte array. The file size can be up to 10gb. So I need to transfer the file "in parts".
Here is my code:
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", _
"attachment; filename=" & HttpUtility.UrlEncode(file.Name))
[code]....
The code snippet works but I have a big problem. The download already starts before the user confirmed the browser download dialog. If the user waits 5min he has already downloaded the 10gb file without accepting it.
I've been using this simple code to download a URL to a file :-
Code:
Shared Function DownloadFile(ByVal URL As String, ByVal LocalDest As String) As Boolean
Try
Dim wc As New System.Net.WebClient
Dim u As New Uri(URL)
[code]....
Then simply load the file in to a string and find the data that I need.
1. Is there a more efficient way of downloading a web page directly into a string without having to save the file physically to my hard drive?
2. Can I specify a timeout somewhere?
I want to request a page(file) of information from a web server using VB code running on a PC. What is a simple piece of code which does this and/or the libraries/calls I need to use.

View 3 RepliesThis code makes the the download dialogue open for the file I want downloaded .
Response.ContentType = "application/octet-stream"
Response.AppendHeader("Content-Disposition", "attachment; filename=" & FileName)
Response.TransmitFile(Server.MapPath("~/Admin/EmailLists/" & FileName))
Response.End()
After the download dialogue opens I need a series of changes to happen on the page, but I have noticed all the code after this code will not run. Anyone know how I can make the page changes occur AND get the download dialogue to pop up?
i want to download a file from a SSL web to my local(C:)
[URL]
Scenario: from the web browser(Internet Explorer), i required to login to the site in order to download the file.
in the vb program i pass in this url to download the file (include my password and username): [URL] but what has been downloaded to my C: is the login page(in myfile.txt) but when i use the url on the web browser[URL] i managed to get the file (the actual file).
Question: is there anyway that i can download the file from a login page?
Dim wc As New System.Net.WebClientGamerTag.Replace(" ", "+")wc.Credentials = New System.Net.NetworkCredential(Email, Password, "http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=" & GamerTag)Dim fx As New System.IO.StreamReader(wc.OpenRead("http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=Dark Slipstream" & GamerTag))Dim str As String = fx.ReadToEndfx.Close()
The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.
In a loop, I need to read a list of URLs from a text file, download the web page, and search for a bit of text using a regex. I used the following code, which triggers the error "WebClient does not support concurrent I/O operations.":

I am developing a website in ASP.Net and VB.Net to allow users to upload and download files from and to an FTP site and my desktop.
I have successfuly got the upload side working.
As far as the download part is concerned, I have so far got it so that when the user goes to the download page, the FTP file list appears so you can see the files that are currently residing on the FTP site.
I was wondering if there is a way that I can program my site so that the user can select one of the files and click on the 'Download' button that I have?
Here is my code so far:

I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?

In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

I am writing a report to an excel template and am trying to insert a page break into the report. Part of my code is included:
Imports msWE = Microsoft.Office.Interop
Dim Rnge As msWE.Excel.Range = excelApp.Range("A20:M20")
Dim excelApp As New msWE.Excel.ApplicationClass
excelApp.Worksheets.HPageBreaks.Add(Rnge)
Now the pagebreak code executes but it does nothing. Its almost as if it is being ignored. Also I have heard that using Microsoft.Office.Interop is not a good idea as it is slow and unstable.
