If someone could explain, I'd appreciate it. [/quote]I've removed the lines of your packetlog which have absolutely no value, and then x'ed out the bytes which also have no value. The first 4 valuable bytes, FF 26 A6 01, I hope you already know how to get these, else leave this forum now. Everything from there on is the packet data, or as you've stated the "packet structure". 01 00 00 00 -> (DWORD)1 (Number of users) 13 00 00 00 -> (DWORD)Length (Number of keys) 9D 9B B2 04 -> (DWORD)Seed (Random value) Then comes the user, then the key list. There are, however, additional keys sent than what you are suggesting.

DarkOne	Thanks for your help Kane.	May 3, 2003, 3:30 PM
Camel	just to elaborate on the seed: it's not really random, the server sends back the same number you send to it. useful if you need to keep track of multiple profile requests, as bnet packets have been known to return asynchronously :-\	May 4, 2003, 2:28 AM

From this, how do I know the following is required when requesting:

(DWORD) 1
(DWORD) LENGTH
(DWORD) SEED
(NTSTRING) USER
(NTSTRING) "profile\age"
(NTSTRING) "profile\sex"
(NTSTRING) "profile\location"

I'm particularly concerned with the three DWORDs. If someone could explain, I'd appreciate it.

From this, how do I know the following is required when requesting:

(DWORD) 1
(DWORD) LENGTH
(DWORD) SEED
(NTSTRING) USER
(NTSTRING) "profile\age"
(NTSTRING) "profile\sex"
(NTSTRING) "profile\location"
(NTSTRING) "profile\description"

I'm particularly concerned with the three DWORDs. If someone could explain, I'd appreciate it.
[/quote]I've removed the lines of your packetlog which have absolutely no value, and then x'ed out the bytes which also have no value.

The first 4 valuable bytes, FF 26 A6 01, I hope you already know how to get these, else leave this forum now.

Everything from there on is the packet data, or as you've stated the "packet structure".
01 00 00 00 -> (DWORD)1 (Number of users)
13 00 00 00 -> (DWORD)Length (Number of keys)
9D 9B B2 04 -> (DWORD)Seed (Random value)

Then comes the user, then the key list.
There are, however, additional keys sent than what you are suggesting. This is the complete key list that was sent:

profile\sex
profile\age
profile\location
profile\description
Record\SEXP\0\wins
Record\SEXP\0\losses
Record\SEXP\0\disconnects
Record\SEXP\0\last game
Record\SEXP\0\last game result
Record\SEXP\1\wins
Record\SEXP\1\losses
Record\SEXP\1\disconnects
Record\SEXP\1\rating
Record\SEXP\1\high rating
DynKey\SEXP\1\rank
Record\SEXP\1\high rank
Record\SEXP\1\last game
Record\SEXP\1\last game result

Thanks for your help Kane.

just to elaborate on the seed: it's not really random, the server sends back the same number you send to it. useful if you need to keep track of multiple profile requests, as bnet packets have been known to return asynchronously :-\
