BNCS 0x09! help please.

"" takes up memory, vbNullString doesn't.

Edit: http://forums.devx.com/showthread.php?t=70074 might clear some things up.

both take up memory. unicode strings just take up a lot more. 4 + (length_of_string * 2), in fact. so, the header of a unicode string would be why "" would not equate to a single null terminating byte.

Did you even read the link?

Brew, find your Starcraft CD and get to work.  There's plenty of information out there about this message and it has been covered numerous of times.

No, "" is not a null string in Visual Basic. We've already had this discussion.

Truth spoken

No, I didn't read the forum link you gave, but I read this, more helpful, page - http://www.aivosto.com/vbtips/stringopt2.html#memorylayout

If there's plenty of information out there about this message, then how come I have to find my Starcraft CD and get to work? Shouldn't I just be able to use the search feature of this forum?

According to bnet docs, half of the IP Address is really where the port would be, same with the address family.. etc, just doesn't make sense. Check for yourself. When really, I believe bnetdocs just might be wrong. I would have posted something about it there, but it doesn't allow the creation of new accounts.... go figure.... and someone PLEASE fix the documentation on the S > C 0x09.

Working on the Receive side now?

Here's my crappy way of doing it:

Code Select Expand

Private Sub SID_Recv_GETADVLISTEX()
Dim GameType()   As Long
Dim param()      As Long
Dim IP()         As String
Dim Status()     As Long
Dim Time()       As Long
Dim GameName()   As String
Dim Pass()       As String
Dim Statstring() As String
Dim GameCount    As Long
Dim I            As Long
Dim tmp          As Variant
Dim NewData      As String
Dim TmpPort      As Long
Dim TmpIP        As String
    On Error GoTo Erred
    GameCount = Packet.GetDWORD
    If GameCount = 0 Then
        Select Case Packet.GetDWORD
            Case 1
                RaiseEvent BNetError("Game Doesn't Exist")
            Case 2
                RaiseEvent BNetError("Incorrect Password")
            Case 3
                RaiseEvent BNetError("Game Full")
            Case 4
                RaiseEvent BNetError("Game Already Started")
            Case 6
                RaiseEvent BNetError("Too Many Server Requests")
            Case Else
                RaiseEvent BNetError("Unknown Game Error")
        End Select
    Else
        For I = 0 To GameCount - 1
            ReDim Preserve GameType(I) As Long
            ReDim Preserve param(I) As Long
            ReDim Preserve IP(I) As String
            ReDim Preserve Status(I) As Long
            ReDim Preserve Time(I) As Long
            ReDim Preserve GameName(I) As String
            ReDim Preserve Pass(I) As String
            ReDim Preserve Statstring(I) As String
            GameType(I) = Packet.GetWORD
            param(I) = Packet.GetWORD
            tmp = Packet.GetDWORD
            tmp = Packet.GetWORD
            TmpPort = htons(Packet.GetWORD)
            TmpIP = Packet.GetString(4)
            IP(I) = Asc(Mid$(TmpIP, 1, 1)) & "." & _
                    Asc(Mid$(TmpIP, 2, 1)) & "." & _
                    Asc(Mid$(TmpIP, 3, 1)) & "." & _
                    Asc(Mid$(TmpIP, 4, 1)) & ":" & TmpPort
            tmp = Packet.GetDWORD
            tmp = Packet.GetDWORD
            Status(I) = Packet.GetDWORD
            Time(I) = Packet.GetDWORD
            GameName(I) = Packet.GetNTString
            Pass(I) = Packet.GetNTString
            Statstring(I) = Packet.GetNTString
            If Config.Game = WAR3 Or Config.Game = W3XP Then
                DecodeMapData Mid$(Statstring(I), 2), NewData
                Statstring(I) = Mid$(NewData, 21)
            End If
        Next I
        RaiseEvent GameListing(GameType(), param(), IP(), Status(), Time(), GameName(), Pass(), Statstring())
    End If
Exit Sub
Erred:
    RaiseEvent CritError(Err.Description, Err.Number, Err.Source, "SID_Recv_GETADVLISTEX")
End Sub

A few notes: htons is an API call ( Private Declare Function htons Lib "wsock32.dll" (ByVal hostshort As Long) As Long ), anything that says tmp=something means the value isn't important (I set it to a variable to make debug.print easier and see what they are). DecodeMapData is a function I found on here (I think it was in Java and I had to port it to VB).

Edit: Some more notes I forgot to mention: The first unknown (DWORD) is the Language ID (Like 1033 (0x409) for enUS). The second unknown (WORD) is usually 2. The last two (DWORDS) are usually 0's.

Last time I checked there was nothing wrong with the documentation on S->C 0x09.  What does BnetDocs say as opposed to that log you just posted?  I can't view BnetDocs at the moment.  That log you posted with comments next to it look ok, are those comments lining up with the formatting BnetDocs has?

Except, the third field (Unknown) is the language ID of the game creator.

No, They are not. According to bnet docs, this would how the data would be parsed:

As you can obviously see, this is an entire 4 bytes off! very misleading.

And btw, thank you Reality for the help with parsing it.

[Barabajagal]

Brew... you're reading the documentation wrong. The header is followed by a DWORD with the number of games listed.

lol

oops......  Then I assume the game type would be.... the first part of the "unknown". okay thank you lol i feel like a moron (which i should)
