VS 2008 Downloading More Than One File From Web Server?
Jul 30, 2009
I am using the web client to download a file. Which works ok.
However, now I have to download many and the number of files to download will change everyday.
I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download?
The web client could download the same file twice?
Private Sub btnStartDownload_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim client As New WebClient()
AddHandler client.DownloadProgressChanged, AddressOf client_DownloadProgressChanged

Been a while since my last posts, so i'm kinda back again ^^ Me & my friends are gonne have our annual LAN party again next weekend, and I'm usually the one in charge of taking care of things, setting up the network etc etc. One thing i've noticed over the past 4 years, is that it usually takes us a day to get everyone set up correctly, all games up to date etc etc.

I am creating a ASP.NET (VB.NET) application that must retrieve a known remote file and return it to the visitor through their browser. I am attempting to use the sample from Microsoft located here: bid=812406 and running into an error 'This stream does not support seek operations'. I'm not sure how to proceed.Here is the code with the error line marked.
Dim ftpWebReq As Net.FtpWebRequest = CType(Net.WebRequest.Create(path), Net.FtpWebRequest)
ftpWebReq.Method = Net.WebRequestMethods.Ftp.DownloadFile
ftpWebReq.KeepAlive = False

I'm working a program, which will download files from my server. But I need, program will download random files from text file on server, for example: I have [URL].
In links.txt are these links:
[URL] .....
If I run a program, it will download first link, after finish download it will download fifth link, second link etc. Downloading of one link works fine for me, but I need download more links...
Code:
theRequest = WebRequest.Create("[URL]")
So I need: theRequest = WebRequest.Create("RANDOM LINK")

I'm downloading a file asynchronously so that it doesn't stall the UI. I'm using a very basic WebClient and calling .DownloadFileAsync.The file I'm downloading is required for additional tasks after it has been downloaded. The issue that I'm running into is that, since the file is being downloaded on another thread, execution on the main thread continues while the file hasn't finished downloading.Is there any way to pause execution while the file is being downloaded? Or is there a better method?

I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

I have developed a VB.NET program using a strongly typed dataset. This dataset has its connection to a SQL Server 2008 R2. The software should now be additionally used offline. The database should be exported to a *.sdf database. If no connection to the SQL server is produced, the software have to try to connect to the *.sdf database.I would like to achieve:
1. Export the data in the SQL Server 2008 R2 database to a local *.sdf file.
2. This *.sdf file has to work as an alternate connection string in the strongly typed dataset.

I am trying to download a file off my web server (easy) but the file its downloading is the updated version of the file running. I finally was able to program my automatic update software the program simply downloads a .txt file from my web server, reads it, and if the the version = (new version here) then download. If not, then go to another form. The problem I am getting though, is when the version is outdated, the file will go to download the new .exe and it gets and error saying "File already exists"

I've got a code in VB that will download a txt file from a website. The problem is I want this file to be downloaded into whatever folder that my program is in. for example, if my program was in C:
andom_folder then I would want this txt file downloaded to C:
andom_folder
Here is some of my
My.Computer.Network.DownloadFile _
("http://www.mywebsite.com/test.txt", _
"define where file should go here")
But in the spot to put where to place the file, I can't just put C:andom_folder because individual users may have this program installed in other parts of there computer.

I'm trying to save this picture from a website automatically, but the problem is there is no file extension. I tried the following code, but it always gives me an error:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
My.Computer.Network.DownloadFile("http://www.hackthissite.org/missions/prog/2/PNG/", "C:PNG.bmp")
End Sub
Error: An exception occurred during a WebClient request.
P.S - I believe the reason it doesn't have an extension is because the picture changes each time the url is loaded (probably through a php code). I'm not too sure on the specifics, but the lack of an extension is what I am having problems with.

I am trying to download a zip file(which contains 4 text files) from a secure website and getting html page in return. If I do it manually I get the zip file. I am using visual basic express. I am very new to .net programing. why I am getting html page instead of the zip file. The manual process is to login, click ebill tab and select the month from list and click download button, which then open up the save dialog box with the zip file name.
