I am creating an update program to go inside of another program I am designing, and I was curious as of how to download the new (updated file) from the internet. Here is the code I have so far.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Okay, I will be passed in an internet address that resolves to a file of some type (.xml, .zip, .mp3, whatever). From inside my VB .NET 2005 program, I need to transfer the file down to the local machine... preferably with events so I can update the screen to show download progress. I also need a way to detect if the file specified by the user actually exists, and retrieve it's file size and compute an estimated download time.
View 1 RepliesI have looked at many other examples that show how download a file from the internet however, these examples don't work because the website I want to download these files from is secure so I don't know how to do this. I am using visual basic express 2008.

View 3 RepliesI need to download files from internet without using FTP, here's my idea:To check version of the program and also download updates.So firstly, when the user enters the splash screen there is a timer which will check updates (downloadTimer) so then downloadTimer starts to download this txt file http://localhost/version.txt and then when its downloaded (and replaced the old one that was on the computer already) and then after that, read the file. If the version.txt contains version 1.0 then pass the check and splash screen closes, main form opens, else then msgbox ("Please Wait!" & vbcrlf & "Downloading updates") and then download updates with the same way from downloading version.txtOh! and also when the file is downloaded (version.txt) save it to "c:programMyApplicationversion" downloading the file without using FTP (if there isn't any other way i could use FTP).File reading could be made with an IO.FileStream thingy.So how do i do the download part?

View 3 RepliesI'm trying to create a simple file downloader (with GUI). I'm pretty new to Vb.net and I didn't find any usefull information about this in the books I own. All tutorials in the wild are making me more frustrated, since the snippets I use, in most cases, are different classes.What should I use? HttpWebRequest/HttpWebResponse or FileWebRequest/FileWebResponse?How do I save the ResponseStream to a file ?Is it possible to use ResponseStream to define the kind of File (FileInfo) Class to get basic file information (size, extension, etc) is it generally neccessary, if GetResponse().headers gives you most of this info ?
My code, which sucks, because I do not know how to realize the saving....
Private Sub btn_downloader_Click(ByVal sender...) Handles btn_downloader.Click
'e.g http://codeigniter.com/download.php'
Dim fileUrl As String = txtBox_url.Text
Dim webUri = New Uri(fileUrl)
[code]....
but I don't know what the buffer is and what it is for. Should I set some static values or any dynamic which deppends on Stream-data ?
How do i exactly check internet connection speed.I have searched around google and found out a method w/c will Download a file like 1mb size, then it will calculate the speed.
View 1 RepliesI'm working on a website in which a user enters a name and then presses a button that prompts the server to create a pdf file according to the information provided, and then sends the file to the user.
I'm testing the website on my laptop without IIS.I needed the pdf to be hebrew and couldn't find a pdfwrite with vb on hebrew; instead, I create a MS Word document and then convert it to pdf using the code below.
This works fine on Firefox, Chrome, and Safari, but on Internet Explorer the page disconnects before the download. It disconnects when the create word statement is executed.

i have a program that calculate a download and up load speed for internet , and i'm doing this by the following for download
1. but the whole code in a timer with interval 1 second
2. calculate the total byte recieved and store it in a variable (s)
3. calculate the new value of total byte received and store it in (s1)
4. s2=s1-s
5. s2 represent the difference in an interval within 1 second is that a download speed ?
i test it with downloading some files from internet using mozilla firefox the values is so close to each other but is that the right way to measure the speed ???
When I click programmatically on a Download link in a webpage, IE 9 does not allow me to automatically download, I have to click on Open, Save or Cancel.
How can I make the selection (Open, Save or Cancel) programmatically?
At the moment I am using the sendkeys command, but, as we know, it is not reliable.
I also do not want to program a mouse click because it is cumbersome and because even in full screen one has to factor in the zoom factor.
I am using SHDocVw.InternetExplorer
The Webbrowser will also do.
My idea is that i want to create a auto-shutdown app that will allow me to auto-shutdown after downloads have completed using IE6. Third part download managers have these built in for example however i would like to make one for IE download dialog. Any ideas on how do start. Detect when a download is active, set time, autoshutdown etc.

I'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
i want to monitor the speed at which my system is currently Downloading and uploading. I dont have any idea how will it can be done.
