tracking internet usage

[sherlockturtle]

Is there a way to get how many bites downloaded/uploaded to the internet since I opend my program? I want to track that.

There is ... but it's not easy! http://pinvoke.net/default.aspx/iphlpapi.GetIfTable

[sherlockturtle]

Thats in C# right? Sorry.. but id prefer vb. Just too get the hard number like 25 bites Downloaded 26 bites Uploaded

Then convert it to vb.net. Go to Google, type "c# to vbnet" and you'll find a bunch of online converters.

You can also try this.

Private startDownloaded As Long
    Private startUploaded As Long
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim interfaceStatistics As IPv4InterfaceStatistics = NetworkInterface.GetAllNetworkInterfaces()(0).GetIPv4Statistics()
        startDownloaded = interfaceStatistics.BytesReceived
        startUploaded = interfaceStatistics.BytesSent
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim interfaceStatistics As IPv4InterfaceStatistics = NetworkInterface.GetAllNetworkInterfaces()(0).GetIPv4Statistics()
 
        Debug.Print(String.Format("Downloaded: {0} bytes", (interfaceStatistics.BytesReceived - startDownloaded)))
        Debug.Print(String.Format("Uploaded: {0} bytes", (interfaceStatistics.BytesSent - startUploaded)))
    End Sub

Ok thanks. It does give me this one error
'IPv4InterfaceStatistics' is not defined.

Hover your mouse cursor over the red underscore, click on the red exclamation mark that appears and click on the 'Import' line.

Try using the correction options. Add ....

Imports System.Net.NetworkInformation

[sherlockturtle]

So. I tried loading some pages and diferent things and nothing seams to happen with recieved and sent?

[Chris001]

Well, look at your immediate window or add two labels/textboxes to your form and use them instead of Debug.Print to show the information.

[sherlockturtle]

Thats what I did. I used a timer. Every 20 seconds

        TextBox1.Text = interfaceStatistics.BytesReceived
        TextBox2.Text = interfaceStatistics.BytesSent

(0).GetIPv4Statistics means use first interface which may not be the one used for your internet.
Try populating a non-sorted combo box with the network interface names, then set the interface using the selected index, something like,

Imports System.Net.NetworkInformation

Public Class Form1
    Private ipv4Stats As IPv4InterfaceStatistics
    Private nic As NetworkInterface
    Private startUploaded, startDownloaded As Long

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        ' don't sort combo items, index used to make selection!
        ComboBox1.Sorted = False
        ' pop list with network adapter names
        Dim nics() As NetworkInterface = NetworkInterface.GetAllNetworkInterfaces
        For Each adapter As NetworkInterface In nics
            ComboBox1.Items.Add(adapter.Name)
        Next
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        ' select adapter to monitor...
        If ComboBox1.SelectedIndex > -1 Then
            nic = NetworkInterface.GetAllNetworkInterfaces(ComboBox1.SelectedIndex)
            ipv4Stats = nic.GetIPv4Statistics
            ' save current Bytes
            startDownloaded = ipv4Stats.BytesReceived
            startUploaded = ipv4Stats.BytesSent
            ' update labels/stats
            UpdateStats()
            ' start timer/auto update stats
            Timer1.Interval = 1000
            Timer1.Start()
        End If
    End Sub

    Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        UpdateStats()
    End Sub

    Private Sub UpdateStats()
        Try
            ipv4Stats = nic.GetIPv4Statistics
            Label1.Text = String.Format("Downloaded: {0} bytes", ipv4Stats.BytesReceived - startDownloaded)
            Label2.Text = String.Format("Uploaded: {0} bytes", ipv4Stats.BytesSent - startUploaded)
        Catch ex As Exception
            Debug.WriteLine(ex.Message)
        End Try
    End Sub

End Class

Does this monitor my computer specifics internet? Or all teh computers on the network. Would it be possible to get each computer on the networks Upload and Download?

-Thanks

Hi Sherlockturtle

You put a small program like a service on each computer which logs their usage on a server then your program get the logs and adds it all up.

Thats what id do

Ian

[sherlockturtle]

Hmm... I could but is there a way to do it from one?

[Edgemeal]

Does this monitor my computer specifics internet? Or all teh computers on the network.

It monitors all traffic on the selected adpater, so for example if the adapter is on a LAN and you transfer files to/from other PCs it would see that traffic as well, so probably not what you wanted sorry,.. it works for me because I have two adapters, one for internet only and one for the LAN.

[sherlockturtle]

ok. Would you have any idea on how to do what I want? What you did still helped.
