[RESOLVED] Can I Dissable Internet Connection With VB?

[kiaraire]

Hello. Im making some program to make my computer easier for use. I would like to know if I can disable the internet connection using VB code. If Its possible, then it will be nice if you show me how.
I got a modem and a router. Got no ideas what details exactly you need but any help will help.

Thanks.

How is disabling the internet connection making the computer easier to use? If someone thinks the internet is complicated they don't have to use it. There may be an API to disable the LAN connection, but again, I don't think this is a good approach.

[jmsrickland]

Why would want to use a VB program to disable the Internet when all you have to do is flip the switch on the back of the modem or just pull the cable out of the PC.

If you are on DialUp then just don't dial in.

[dee-u]

For dial-up but I have not tested it...

Const Internet_Autodial_Force_Unattended As Long = 2

Public Declare Function InternetAutodial Lib "wininet.dll" (ByVal dwFlags As Long, ByVal dwReserved As Long) As Long
Public Declare Function InternetAutodialHangup Lib "wininet.dll" (ByVal dwReserved As Long) As Long

Private Sub Disconnect()
 Dim lResult As Long
 lResult = InternetAutodialHangup(0&)
End Sub

[kiaraire]

danecook21: I dont want others to use the internet on my computer in particular times each day. Beside that, I need to turn it off because the internet in other computer will work faster.

jmsrickland: Good question. Its because I need it to turn off automaticly when im not at home and I want it to be part of my new program.

dee-u: I cant understand how it works. Can you specify more details please?

Thanks.

[westconn1]

to turn off broadband internet you would need to disable your network connection
note dee-u solution only for dial up type connection, as he says
another possibility is to change the proxy settings to a non existent proxy, which would just prevent the data being returned to your computer

either of those can easily be reverted by a user, best solution is to lock your computer with a good password

I have just come across this InternetHangUp API, would it help? I know this thread is somewhat old but I can't pass the opportunity to refer the API.

[jmsrickland]

I have a gut feeling that API is for DialUp,

[CDRIVE]

I have a gut feeling that API is for DialUp,

What was your first clue! Just kidding. The OP is using dial-up but that API isn't working for me so I doubt that it will work for him. I called it like this:

Option Explicit
Private Declare Function InternetAutodialHangup Lib "wininet.dll" (ByValdwReserved_ As Long) As Long

Public Function HangUpModem() As Boolean
    If InternetAutodialHangup(0&) = 0 Then HangUpModem = False Else HangUpModem = True
End Function

Private Sub Command1_Click()
   HangUpModem
End Sub

Post edited - disregard very buggy command - wouldnt work on my daughters laptop.

code deleted

[CDRIVE]

Just want the OP to know that I've spent the better part of today trying every damn API listed in this thread and every link to API's. None of which produced any results. I'm totally bummed out and burned out!

One of the shortcomings of MSComm is the fact that it can't gain priority control over a port in use. If it could, this would be soooo easy.

[CDRIVE]

Sub LanOff()
Dim ws
Set ws = CreateObject("Wscript.Shell")
ws.Run "netsh interface set interface " & Chr(34) & "Local Area Connection" & Chr(34) & " DISABLE " , 0, True
Set ws = Nothing
End Sub

The OP is NOT using a LAN.

[CDRIVE]

Oh, this is really the pits! I've been telling everyone in this thread that the OP is using Dial-Up because he said he's using a Modem. Well, I don't really know that, because people also use the term Modem for cable and DSL, even though it's a misnomer.

The worst part is that there is another active thread that the OP does want to access the Modem and I've been getting these two threads all mixed up. Gee, I haven't even begun to imbibe yet!

Not sure if anyone's mentioned it yet (I did read through posts...) but you can get yourself a wireless broadband usb device - plug and play.
Of course you would have buy monthly service as well or it could be on per-mb-basis.

I have browsed kiaraire's threads and this is the only one that is internet related. If you are referring to this thread then sure you are mixed up, unless svg3414 and kiaraire are the same person.

[CDRIVE]

he did say

Yes he did. I hope he comes back and clarifies this issue.

Yes, I clearly admitted that I was all screwed up,, and yes, that's the thread. Hey, what can I say....? There is also an apology to you in that thread.

[kiaraire]

Sorry Nothing could help me. I even checked the other thread you gave me,
Maby I dont have enought knowledge to do it right. Its not urgant so thank you all anyway.

unless svg3414 and kiaraire are the same person.

Nah. I dont like numbers inside a nickname.

[CDRIVE]

You know there are 20 posts (including this one) in this thread but you've only made three and only 1 answered any questions. You have to help by answering questions. Do you want to do this or not?

[kiaraire]

Sure I do. Ask a question.

[CDRIVE]

Sure I do. Ask a question.

A good start would be to answer the questions in this thread.

A cheap Linksys router can limit internet access from a specific PC based on time and day of the week. Is that automation possible in your enviroment?

I think this is a good solution!

Good idea but I don't have it and I don't wanna buy. Even not to waste a coin on a little chewing gum.

What about devcon? Simply you can enable/disable the lan device (in case you are using A/DSL).

DevCon: http://support.microsoft.com/?scid=k...311272&x=9&y=6

This is the line i'm using in my app, to enable a wifi device.

Shell "cmd /c " + Chr(34) + "devcon.exe enable PCI\VEN_168C*"

By replacing the word "enable" to "disable" will disable the device that matching before the asterisk (*).

[CDRIVE]

That's a slick tip Jim and simple too!!

Can't you execute ipconfig /release?
That would work tho,

Shell "IpConfig /release"

And

Shell "IpConfig /renew"

To get the connection back.

[jmsrickland]

How do I get IPCONFIG to stay up. When I try to run it using a .BAT file or shelling it with VB it pops up real fast, displays a bunch of stuff, and then goes away. How to keep it up?

You could put the output to a text box.

Option Explicit
' Add reference to Windows Script Host Object Model.
Private execAssem As IWshRuntimeLibrary.WshExec

Private Sub Command1_Click()
    Text1.Text = ""
    With New IWshRuntimeLibrary.WshShell
        Set execAssem = .Exec("IPCONFIG /all")
    End With
    Command1.Enabled = False
    Do
        With execAssem
            With .StdOut
                If Not .AtEndOfStream Then
                    Text1.SelStart = Len(Text1.Text)
                    Text1.SelText = .ReadAll()
                End If
            End With
            If .Status <> WshRunning Then Exit Do
        End With
        DoEvents
    Loop
    Command1.Enabled = True
End Sub

Just go into the Vista Help&Support and search on parental controls.

It's already built in.

Why would you want to keep it up anyway?

Works great for me.

Private Sub Form_Load()
 Dim InternetStatus As String
 
 Open App.Path & "\InternetStatus.txt" For Input As #1
 Line Input #1, InternetStatus
 Close #1
  
 If InternetStatus = "Disabled" Then
   Command1.Caption = "Enable Internet"
 Else
   Command1.Caption = "Disable Internet"
 End If
End Sub

Private Sub Command1_Click()
 Open App.Path & "\InternetStatus.txt" For Output As #1

 If Command1.Caption = "Disable Internet" Then
   Command1.Caption = "Enable Internet"
   Shell "IpConfig /release"
   Print #1, "Disabled"
 Else
   Command1.Caption = "Disable Internet"
   Shell "IpConfig /renew"
   Print #1, "Enabled"
 End If
 
 Close #1
End Sub

[Edgemeal]

Ipconfig /release doesn't work for me, I have a static IP, guess it only works on DHCP setups.

[masterkert3]

To read it, what else.

Ipconfig /release or Ipconfig /renew won't print anything.

[Edgemeal]

Ipconfig /release or Ipconfig /renew won't print anything.

It does in my case (Static IP).

>ipconfig /release *Local*
Windows IP Configuration
Adapter Local Area Connection is not enabled for Dhcp.

>ipconfig /renew
Windows IP Configuration
The operation failed as no adapter is in the state permissible for this operation.

[jmsrickland]

Ipconfig /release or Ipconfig /renew won't print anything.

I wasn't asking because of that particular case; I was just asking how to keep it up so I can read whatever the output is on the black screen. For example: ipconfig.exe /displaydns

[jmsrickland]

Ipconfig /release doesn't work for me, I have a static IP, guess it only works on DHCP setups.

I have a static IP. So why does it work for me?

[masterkert3]

Shell "cmd /K ipconfig", vbNormalFocus

That'll keep the cmd open.
