    I've been searching around the Internet for ages now.
    Never did I saw a working code to check and see if the
    End-User has a valid Internet Connection.

    Checking Registry, WinInet.dll, Pinging, URL Exists,
    DSN Resolves, API, and even useless Winsock Control.

    None of these things really worked.
    People these days are connected to all types of devices.

    Modem, LAN, Proxy, DSL, T1, T2, T3, DS3, OC3
    All kinds of speed.

    How can Microsoft do this? and not make it public information
    on how to determine if a User is Connected?

    Anyone who got a REAL WORKING API CALL, DEMO, OR EXAMPLE PROJECT? If you do please give me the URL and I can take
    it from there.

    Talking How About This...

    In a Module This:
    Code:
    Public Const ERROR_SUCCESS = 0&
    Public Const APINULL = 0&
    Public Const HKEY_LOCAL_MACHINE = &H80000002
    Public ReturnCode As Long
    
    Public Const WM_USER = &H400
    Public Const PBM_SETBARCOLOR = 1033
    Public Const PBM_SETBKCOLOR = 8193
    
    Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
    
    Declare Function RegCloseKey Lib "advapi32.dll" (ByVal _
    hKey As Long) As Long
    
    Declare Function RegOpenKey Lib "advapi32.dll" Alias _
    "RegOpenKeyA" (ByVal hKey As Long, ByVal lpSubKey As _
    String, phkResult As Long) As Long
    
    Declare Function RegQueryValueEx Lib "advapi32.dll" Alias _
    "RegQueryValueExA" (ByVal hKey As Long, ByVal lpValueName _
    As String, ByVal lpReserved As Long, lpType As Long, _
    lpData As Any, lpcbData As Long) As Long
    
    
    Public Function ActiveConnection() As Boolean
    Dim hKey As Long
    Dim lpSubKey As String
    Dim phkResult As Long
    Dim lpValueName As String
    Dim lpReserved As Long
    Dim lpType As Long
    Dim lpData As Long
    Dim lpcbData As Long
    ActiveConnection = False
    lpSubKey = "System\CurrentControlSet\Services\RemoteAccess"
    ReturnCode = RegOpenKey(HKEY_LOCAL_MACHINE, lpSubKey, _
    phkResult)
    
    If ReturnCode = ERROR_SUCCESS Then
        hKey = phkResult
        lpValueName = "Remote Connection"
        lpReserved = APINULL
        lpType = APINULL
        lpData = APINULL
        lpcbData = APINULL
        ReturnCode = RegQueryValueEx(hKey, lpValueName, _
        lpReserved, lpType, ByVal lpData, lpcbData)
        lpcbData = Len(lpData)
        ReturnCode = RegQueryValueEx(hKey, lpValueName, _
        lpReserved, lpType, lpData, lpcbData)
        
        If ReturnCode = ERROR_SUCCESS Then
            If lpData = 0 Then
                ActiveConnection = False
            Else
                ActiveConnection = True
            End If
        End If
    RegCloseKey (hKey)
    End If
    
    End Function
    And For use in a form This:

    Code:
    Private Sub Command1_Click()
        If ActiveConnection = True Then
            Call MsgBox("You have an active connection.", vbInformation)
        Else
            Call MsgBox("You have no active connections.", vbInformation)
        End If
    End Sub
    I have tested only in Modem Standard and With ISDN with no
    problems.

    Hope this is it..

    Saludos...

    Unhappy

    Yea, that works..I know

    But if you are using Windows 2000. OOopps! hmmm guess what?
    It failed. And that doesn't support LAN, Proxy.

    This is so stupid, can't never find a working code.
