Ive been looking around for the last 6 hours trying to find a beginners explanation on how to get data from packets sent from battle.net. I didnt find it.

Things I know:

The function StrtoHex is used
Asc(Mid(Data, 2, 1)) gets the packet id

I have Grok's Debug Output and I have been examining the packets. Thats about all I know. Could somebody please give me just a little info on how this works?

This is as good as it gets, nobody wants to waste their time teaching people about packets, sorry. I learned by noticing the differences in packet logs and by using Grok's debug output.

So.. You use StrToHex then your bot examines the hex to get the values out of it?

Ok, I had trouble with this too.

BNCS Headers are like so

&HFF (Byte) + PacketID (Byte) + PacketSize (WORD)

So basically a BNCS header is a DWORD (4 Bytes).

This is the way I looked at the header, looked at it as a string.
"ABCDDDDDD..."

A = &HFF, BNCS constant
B = PacketID
C = PacketSize
D = Packet's Data

[quote]
Mid(Data, 2, 1)

This is just taking the "B" packet.

I'm not quite sure what you are asking specifically.

I am a newbie like you too but I know some stuff.

I have made this PacketDebuffer Class and posted it earlier. This could help you with parsing a packet.

Here is how you might use it to parse the parts of a BNCS header from the packet

[code]
Dim PDebuf As PacketDebuffer
Set PDebuf = New PacketDebuffer

With PDebuf
.DebuffPacket Packet
PacketConst = .DebuffBYTE
PacketID = .DebuffBYTE
PacketSize = .DebuffWORD
End With
[/code]
