[RESOLVED] Listing IP of PCs connected to me...

Hello. I already have winsock server and client programs. i have one server and about 10 clients.

How do I list all the IP addresses of computers connected to the server? Can I also do this in the clients?

One way would be to shell out the netstat dos command and output its results to a textfile. Then read it back in to your app.

VB Code:

Option Explicit
 
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hWnd As Long, ByVal lpOperation As String, _
ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
 
Private Const SW_HIDE As Long = 0
Private Const SW_SHOWNORMAL As Long = 1
Private Const SW_SHOWMAXIMIZED As Long = 3
Private Const SW_SHOWMINIMIZED As Long = 2
 
Private Sub Command1_Click()
    'If running XP then you can use the -ano switch.
    'Also, if not running XP then the path to CMD.exe will be different. This can be dynamically obtained
    'by using the GetSystemDirectory API
    ShellExecute Me.hWnd, "Open", "C:\Windows\System32\CMD.exe", " netstat -ano >C:\Ports.tmp", "C:\", SW_HIDE
    'If running pre-XP then just -ao
    'ShellExecute Me.hWnd, "Open", "C:\Windows\System32\CMD.exe", " netstat -ao >C:\Ports.tmp", "C:\", SW_HIDE
    'ToDo: After process is completed, read the file back in.
    '...
End Sub

how about this

VB Code:

Private Sub socket_ConnectionRequest(Index As Integer, ByVal requestID As Long)
 
  Load Socket(Socket.UBound + 1)
  Socket(Socket.UBound).Accept requestID
  [COLOR=darkred]List1.AddItem "Connection request id " & requestID & " from " & [b]Socket(Index).RemoteHostIP[/b][/COLOR][b] [/B]
End Sub

or

VB Code:

Private Sub ListIPs
For i = Socket.LBound to Socket.UBound
   if socket(i).state = 7 then [COLOR=darkred]List1.AddItem "Connection  " & i & [b]Socket(Index).RemoteHostIP[/b][/COLOR][b] [/B]
next i
End Sub

Thanks dlern and RobDog888!

RobDog888, I am concerned with my classmates. I don't think they will understand what you gave me. Hehe. But it's good! Thanks!

dlern, this is better because it is more straightforward.

Thanks everyone!
