A sampel would be nice.. Thanks alot..

try this one. hope this will help to solve your problem.
i just barrowed this code. :D

Declarations

VB Code:

Public Const RAS_MAXENTRYNAME As Integer = 256
Public Const RAS_MAXDEVICETYPE As Integer = 16
Public Const RAS_MAXDEVICENAME As Integer = 128
Public Const RAS_RASCONNSIZE As Integer = 412
Public Const ERROR_SUCCESS = 0&
 
Public Type RasEntryName
    dwSize As Long
    szEntryName(RAS_MAXENTRYNAME) As Byte
End Type
 
Public Type RasConn
    dwSize As Long
    hRasConn As Long
    szEntryName(RAS_MAXENTRYNAME) As Byte
    szDeviceType(RAS_MAXDEVICETYPE) As Byte
    szDeviceName(RAS_MAXDEVICENAME) As Byte
End Type
 
Public Declare Function RasEnumConnections Lib _
"rasapi32.dll" Alias "RasEnumConnectionsA" (lpRasConn As _
Any, lpcb As Long, lpcConnections As Long) As Long
 
Public Declare Function RasHangUp Lib "rasapi32.dll" Alias _
"RasHangUpA" (ByVal hRasConn As Long) As LongPublic gstrISPName As String
Public ReturnCode As Long

Procedure

VB Code:

Public Sub HangUp()
Dim i As Long
Dim lpRasConn(255) As RasConn
Dim lpcb As Long
Dim lpcConnections As Long
Dim hRasConn As Long
lpRasConn(0).dwSize = RAS_RASCONNSIZE
lpcb = RAS_MAXENTRYNAME * lpRasConn(0).dwSize
lpcConnections = 0
ReturnCode = RasEnumConnections(lpRasConn(0), lpcb, _
lpcConnections)
 
If ReturnCode = ERROR_SUCCESS Then
    For i = 0 To lpcConnections - 1
        If Trim(ByteToString(lpRasConn(i).szEntryName)) _
            = Trim(gstrISPName) Then
            hRasConn = lpRasConn(i).hRasConn
            ReturnCode = RasHangUp(ByVal hRasConn)
        End If
    Next i
End If
 
End Sub
 
Public Function ByteToString(bytString() As Byte) As String
Dim i As Integer
ByteToString = ""
i = 0
While bytString(i) = 0&
ByteToString = ByteToString & Chr(bytString(i))
i = i + 1
Wend
End Function

Using the HangUp Procedure

Once you have copied all required code into your project, you can hang up all connections to the telephone network by calling the procudure HangUp:

VB Code:

Call HangUp

Dear qhyzme

I have tried the way you suggested but nothing seem to be happening? Is it the coding is for dial up or broadband? The computers which i intend to disconnect its internet connection are using broadband. Need more help

Thanks alot

This line is having some problem

VB Code:

Public Declare Function RasHangUp Lib "rasapi32.dll" Alias _
"RasHangUpA" (ByVal hRasConn As Long) As LongPublic gstrISPName As String
Public ReturnCode As Long

The error message is Compiler error Expected: end of statement

Please help

Try doing this:

VB Code:

Public Declare Function RasHangUp Lib "rasapi32.dll" Alias _
"RasHangUpA" (ByVal hRasConn As Long) As Long  'split them up
 
Public gstrISPName As String
Public ReturnCode As Long

Thanks alot benmartin101 yesterday i have just found the original site which this coding was in and i have split up the coding but it still can't work.

Did anyone tried this coding before?? Can it work on your computer which is to disconnect the internet connection on LAN? I have tried but still it can't work. Hope someone can tell me or show me some example on this.

Can you guys help me to check this site out and try the coding
http://www.developerfusion.co.uk/show/247/

Can anyone get the coding to work?? What do we need to get it to work??

Please help me...

You guys i have given up on this coding as i have find out that the code can only cater to dial up and not for LAN connection.

Its ok as i have found a new way to do this.
Thanks to all who have help me. I have start a new thread so please help me there ok. Thanks alot You guys are the best :thumb:
