Help with sockets/winsock programming

[Valleriani]

Right Now I've been working on a text based game for fun. It was working fine but they I relized that you need to shut/close the ports. Before I was just opening ports and not shutting them, no problems because it will just go to the next port. But this way is not correct. I started shutting the ports but now I get the error of the 'user' not being in the correct socket when its checking etc. For example: User 1 logs in, user 2 logs in as well. User one logs off, User 2 tries to talk or such but cannot because the server thinks theres only 1 socket being used.. (Basicly thinks hes in socket one since you minus a socket on logoff) I personally don't know how to fix it. I tried a few things with ports but they didn't work correctly, I am stumped to how to fix it. Personally I think it should move or detect theres a missing port and go to the next one since its closed or something like that. I'm not really sure.. Welp, here is some coding....

'Enable listening on port 25001
Private Sub Form_Load()
    Dim i As Integer
    packetDelimiter = Chr$(0)
    Set dbdata = OpenDatabase(App.Path & "/data/data.mdb") ' opens database file
    RoomLimitNumber = 0
    ItemLimitNumber = 0
    Call LoadRooms
 
    'Pause
    For i = 1 To 50
        DoEvents
    Next i
 
    Call LoadItems
    'Load all the sockets and timers
    WStcpServer(0).LocalPort = 25001
    WStcpServer(0).Listen
    num = 0 'User count
End Sub
 
'When a connection is recieved, goto verifying stages
Private Sub WStcpServer_ConnectionRequest(Index As Integer, ByVal requestID As Long)
    num = num + 1
    Load WStcpServer(num)
    Load Timer3(num)
    Load tmrrefresh(num)
    WStcpServer(num).Accept requestID
    'Add a user to the arrays. Prevents making a 'limit' to the amount of users you can have.
    MsgSend = "¿caut¶" & "Verify" 'Ask for verification
    blnRetVal = WinsockSend(WStcpServer(num), MsgSend)
End Sub
 
'Preform this when a client closes or disconnects
Private Sub WStcpServer_Close(Index As Integer)
    Dim i As Integer
        If Not users(Index) = "" Then 'If there was no connection or bad login, then don't do this, otherwise continue
            txtMain.Text = txtMain.Text & "Disconnected: " & WStcpServer(Index).RemoteHostIP & ": " & users(Index) & vbCrLf
            For i = WStcpServer.LBound + 1 To WStcpServer.UBound
                If userroom(i) = userroom(Index) Then
                    If users(i) = users(Index) Then
                    Else
                        'Leave the game message
                        MsgSend = "~g" & users(Index) & " has just left the game!"
                        blnRetVal = WinsockSend(WStcpServer(i), MsgSend)
                    End If
                End If
            Next
            users(Index) = "" 'Clear the username from the users. Frees up a socket.
        End If
        WStcpServer(Index).Close
        Unload WStcpServer(Index)
        Unload Timer3(Index)
        Unload tmrrefresh(Index)
        num = num - 1
 
End Sub

and basicly something id use would be..

'Chat Sub
Private Sub PublicChat(ByVal Index As Integer, Comarray() As String, ComI As Integer)
    Dim i As Integer
 
    'Send to all users in room
    For i = WStcpServer.LBound + 1 To WStcpServer.UBound
        If userroom(i) = userroom(Index) Then 'In the room?
            MsgSend = "~yFrom " & "~w" & users(Index) & "~y: " & Comarray(ComI)
            blnRetVal = WinsockSend(WStcpServer(i), MsgSend)
        Else
        End If
    Next
 
End Sub

Everything is FINE until someone disconnects because it doesn't know how to handle exiting properly i think.
Personally the getdata is fine, but its the sockets. I do not know how to move or skip sockets that aren't in use. Another example would be 2 people on, one disconnects, the first person disconnects.. so person on socket 2 other person cannot talk because its trying to send the data to a invalid socket (thinking its socket 1 I believe) Something like that.. Any help? Need more info?
