Calculate A Download And Up Load Speed For Internet?
Jan 4, 2012
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 ???

I have very well knowledge about vb.net but I am suffering from 32 bit code and 64 bit code problem. I had done the code for how to check internet connection but it display's LAN connection but it doesn't shows that the Internet access, so I can't understand that what can I do to solve this problem and also I want to calculate internet speed, I put the 64 bit code but it displays the LAN speed but I want to display internet access speed.
The code is:
Imports System.Net.NetworkInformation
If NetworkInterface.GetIsNetworkAvailable Then
lblstatus.ForeColor = Color.Green
lbltype.ForeColor = Color.Green

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"

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 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]

I 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?

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.

I 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.

I'd like to write a simple application in VB.Net using VB.Net Express 2008 (uses .Net 3.5), but it's a bit slow to start on my average computer.
1. When starting a .Net application while no other was loaded before using the same version of the framework, I guess Windows must load the whole framework from disk into RAM. Using eg. Process Explorer, how can I check if the framework is already up and running?
2. Is there a way to speed things up? Is there a way to load the framework at boot time? Pre-compile the application to avoid JIT compiling (provided it makes a difference for a small application)? Other tricks to know?
3. Out of curiosity, is Mono smaller/faster than MS.Net? I don't need more than the basic, run-of-the-mill controls.

I'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.
