Yes, packet log(s) would be nice since more than half the time when people post code, they do not show how the variable is set, what this function does, and stuff like that.  Seeing a packet log of your bot interacting with Battle.net would really help us figure it out and help you towards success

Hrmm i packet logged it, came up with some weird stuff... here it is

its like they put together, hrmm... ideas?

[Hdx]

Why are you echoing back the hashstring?
It isn't sapost be sent to b.net it is saposto be used in the CheckRevishion function, with the hash files, Currently the Z() function in BNetAuth.dll
~-~(HDX)~-~

[Spilled]

I dont get what you mean by echoing, can you be more specific, thx for the help.

[Hdx]

You recive
2  Hide  Hide  106  Recv
.A=21278070 B=667570578 C=302084050 4 A=A^S B=B-C C=C+A A=A+B.
in S->C 0x50

Then you send it back in 0x51.
Take out the InsertNonNTString Hashing.Hash in your sub, that should fix it..
Also for them being bunched together, dont worry, the server can pick them apart using the Packet header

ahh, there we go, thx HDX and Userloser for your help, much appreciated

Ok, ran into anohter problem here and i thought i would be more appropriate to just post it here instead of starting a new topic so sry about the double post everyone, but heres my Code:

Variable Declares:

Code Select Expand


Public Hashing As HashingShit
Private Type HashingShit
    Checksum As Long
    ClientToken As Long
    ServerToken As Long
    VersionID As Long
    ExeInfo As String
    Hash As String
    HashedData As String
    MpqName As String
End Type


heres the case where i recieve 0x50:

Code Select Expand


        Case &H50
             Hashing.ServerToken = Val("&H" & Connection.StrToHex(StrReverse(Mid(strData, 9, 4))))
             Hashing.Hash = Mid(strData, 38, Len(strData) - 2)
             Hashing.MpqName = CStr(Mid(Mid(strData, InStr(1, strData, "IX86ver"), Len(strData)), 1, 12))
                SendPacket51


And heres where my problem is, in this sub where it sends 0x50, i was getting it back as bad game version, (HDX tried to help me on PM's but we didnt finish), i think the problem is:

Code Select Expand


cRev = C(Hashing.HashedData, Hashing.ServerToken, ProductID, Val1, Val2, ClientToken)


Because i put a break there and Hashing.HashedData is an empty string variable.

Any ideas anybody? HDX's help got it to send now its just responding as bad game version and i think this may be the problem, thanks in advance...

Put a break after that code (or step over once) and see if it's still an empty string variable. When you put a break on something, it stops before executing the code, not after.

If i put the break after that line of code, vb crashes but if before it doesnt, any ideas kane?

                    SendPacket &H51
    End Select
End Sub


I think its a problem with the Hashing.HashedData, can anyone spot my error? Thanks in advance everyone.

[tA-Kane]

If i put the break after that line of code, vb crashes but if before it doesnt, any ideas kane?

Breakpoint C?

If it's a library call (eg, you're using SomeGuysBnetUtilities.dll or somesuch), then make sure you're passing your data correctly; make sure your data types and their values are correct.

[Spilled]

Thats what i was doing, putting breakpoints and checking my values in my variables, all seems appropriate but Hashing.hasheddata was empty. Ideas?

[Hdx]

Feel like posting the values of some vareables?
I have a hunch that Hashing.HashedData = vbNullstring.
And THAT is what is causing your error: to fix it place: Hashing.HashedData = String(20, vbNullChar) right befor you call c()
Also you can deleat Hash = String(20, vbNullChar)
Oh and ADD

OPTION EXPLICIT TO THE VARRY TOP OF YOU MOD!
If its not already there >.<

~-~(HDX)~-~
[Edit]
Haha I was right You need to fix your vareable.
I've noticed that BnetAuth has NO handeling of empty parameters, causing major crashing.
[/Edit]

[Spilled]

yea, i just added that and the erroring stopped, now its sending 0x51 and im recieving the response of bad game version again, i checked if Hashing.HashedData had a value and it does now, i packetlogged this:

Well, Just by the packt log I can tell that your not using the right hashes. last edit time should be: 10/13/03 not 02/23/05
Use these: http://hdx.no-ip.org/Files/D21.10.zip
