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?

Similar to the CSV file which can be downloaded from [url] . How can I downloada file which requires authentication? I can simply use My.Computer.Network.DownloadFile[url] To download the file which is available in public. I tried setting the username and password as per the MSDN documentation but all I get is the HTML content of the login page.

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:

How to create a login page using visual basic which will save the information I put into my Username box and my Password box in a separate text file on my computer? I have seen various tutorials on how to make a login page that will ONLY accept the username and password info that you have put in the code, I'm looking for a bit of code that will allow any info entered into these boxes to be saved and stored as a txt file.

I am trying to create a small program that checks [URL] for a work order every minutes. While I don't know of any API that I can use, I think it would be easy enough to simply check the page and see if there are any new work orders listed. The question I have is how to access the work order page. Every a few minutes field nation logs you out of their website. At that point I am required to log back in again to access my account. How can I automate or bypass this process so that my program and regularly check for new workorders?

It is simply a "Y" in the road. If they are Company A, then I want to send the username and password over to that website and log them in as if they typed it in there. If they are Company B, then the same thing but with a different website. I do not know the term for this, so the google results are not very pretty.I can not do this with a query string (not that I'd want to anyway) as I do not want the username/pw to be visible.Here is the other weird thing. This can be done via a simple HTML <FORM> and Submit button as I have tested it. But I want to do it all in VB.NET code. How is it that it is possible with some simple HTML but not possible in VB.NET? I guess it could be a security thing, right? What do the good guys like us do when we legitimately just want our employees to go to one login page, enter their username/pw, and then (based on their username) send them to either pageA.aspx or PageB.aspx which receives their username/pw that they only entered once before on the first page?

So i've been working on a page for a project where the person logs into a login page and then can see a list from the database of employees. everything is working except for one problem. If someone puts in a username and password, username= a and password=b, for example it still allows that individual to view the next page and doesn't throw the error that i have enbedded on the login page to say sorry you have the incorrect password/username. The working code that i have so far is below:

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?

all I want is a function like this:
[URL] but then with the option to provide username & password. I have managed to do this with the webbrowser, first logging in then go to webpage and get source code but this takes much longer than just getting the source code...
Is there any way to do this? I found this:
[URL]
I tried with &username=...&password=... in the URL but it didn't work

I can't seem to figure this out. Below is some HTML on a webpage after I've logged in. The HTML is generated by javascript, and not sure how to do the same thing they do.On the site I simply click the "Georgia KMA" cell in the table that pops up, then click "OK" button at bottom.I've gotten the login done, now I'm stuck, can't get a "Click" to occur in the cell. I've got the javascript up and can't identify for sure what handling the click input.What I'm doing is writing vbscript to automate a file download.I don't have access to modify the site in any way.I have verified by using a msgbox that the DIV item 107 is the correct item for what I want. with this code it doesn't highlight the cell so when I click OK it doesn't do anything but tell me to select one of the listed items.
My Code so far:
'code to halt internet explorer
Sub WaitForLoad(obj)

This 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?

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.
