View 1 RepliesWe recently started playing with a vb.net 2008 WebClient on a Windows 7/64 workstation to download files from a web site to the local machine.It works except that we cannot detect if the URL is invalid. It doesn't throw an error. If we use Async it does trigger the Download Complete event but there was no file since the URL was incorrect.Is there a way to detect an incorrect URL?I also noticed that the events does not give you either the URL or the file?

View 2 RepliesI've been trying for a while to use a method I've found on the net to login to a webpage then download zip files off the page.Here is what I am doing:
Code:
strURL = "https://www.someurl.com/"
Client = New WebClient()
[code].....
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.
I have a weird bug with webclient. I made an app a while ago which uses webclient to download a small thumbnail image.. and I rememeber when I first made it, the first time webclient was used to download the image it always took 15 sec+ to download it, but after the first it always downloaded quickly (in like 1 sec) .. but then the problem went away for me and it always downloaded fine.but now someone else who uses my app is having the slow image download problem apparently around 50% of the time it downloads the thumbnail images. so does anyone know what might be causing this? As I said, I don't have the problem any more on my comp - but I don't know why :s

Well an alternative way is by just showing the connection speed which is:
Dim AllNetConn() As NetworkInterface = NetworkInterface.GetAllNetworkInterfaces
Dim IntConnSpeed As Integer = AllNetConn(0).Speed / 1024
Dim StrConnSpeed As String = IntConnSpeed & " Kbps"

But i need something more specific like the download/upload speed.. I know that i could make my program download a file with the size of 100kb and measure how much time it took to download but i dont know how to measure the time...
Is it possible to control the download speed in vb.net
For example if the client downloading speed is 45kb per sec can i change to 40kb per sec.
i want this to only effect my application and not the web browser or any other applications.
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?

I have a ftp download in a background session that updates to a progressbar, file download takes about 2 minutes and it works great, gives me the length that has been downloaded, total size, and the bytes remaining.I thought it would be cool to have the speed show as well but not sure I have all the info to work with, or how exactly to do it. This is my loop, and what I do have works fine just want to have the speed show as well if possible:[code]
View 5 RepliesI'm trying to code a program that can download multiple files at once (on different threads of course).I have created a custom listview component that will allow me to add a progressbar directly to it.What my real question is, how can i take a url given by the user from an input box and create a new webclient to handle the download asynchronously and also report the progress without disturbing all of the other downloads in progress?
View 10 RepliesI created a software which download files from the web. I also added a progress bar which shows the download progress. Every thing works fine.
Now:
- How can I add a label that will calculate the time left for the file to be downloaded and another label that will tell the speed of the download?
- Would it also be possible to add a label which calculates the size of the file that is begin downloaded?
Here is what I declared:
Imports System.Net
Public Class Form1
Dim WithEvents Download As New WebClient
Dim WithEvents Download1 As New WebClient
Friend WithEvents Label1 As System.Windows.Forms.Label
Here is what I have under the download button:
Download.DownloadFileAsync(New Uri("URL" & ComboBox1.Text & ".rar"), Textbox1.Text & "" & ComboBox1.Text & ".rar")
And here is what I have under Download_DownloadProgressChanged:
ProgressBar1.Value = e.ProgressPercentage
Label1.Text = e.ProgressPercentage & "%"
If ProgressBar1.Value = 100 Then
MsgBox("Download Completed!", vbInformation, "Info")
Label1.Text = "0%"
how to limit the transfer rate (for example, a limit of 120KB/s) of an upload or download through a Visual Basic program?
