In case anyone needs it :

This is what I wrote some time ago for reading chat messages from array :

Code:

function TPWChat.GetMessage(Indx: Integer; length: Integer): string;
var
  written: cardinal;
  eax: cardinal;
  indexcalc: cardinal;
  Str: array [0 .. 240] of Widechar;
begin
  if Indx < 199 then
    begin
      indexcalc := (((Indx - 1) * $1C) + $18);
      ReadProcessMemory(Pidhandle, ptr(chatbase), @eax, sizeof(eax), written);
      ReadProcessMemory(Pidhandle, ptr(eax + indexcalc), @eax,
        sizeof(eax), written);
      ReadProcessMemory(Pidhandle, ptr(eax + $0), @Str, length, written);
      Result := Str;
    end;
  if Indx >= 199 then
    begin
      ReadProcessMemory(Pidhandle, ptr(chatbase), @eax, sizeof(eax), written);
      ReadProcessMemory(Pidhandle, ptr(eax + $15B0), @eax, sizeof(eax), written);
      ReadProcessMemory(Pidhandle, ptr(eax + $0), @Str, length, written);
      Result := Str;
    end;
end;

Very messy code, and I know that typecasting widestring to string is not safe at all, but I couldnt be arsed to fix it back then. Just dumping this here.

Indx is the current chat index (The counter that counts even though you cleared your log), length is the length of the message you wish to copy / 2 (unicode).

Hope this helps a bit, cheers...

i have one question about Auction, iam trying remake AH for better and faster searching, but i stuck on this.....

auctionid.txt

Code:

ID		group		full name
19		19		☆Bronze Sword
4688		19		☆☆Bronze Sword
4499		19		☆☆☆Bronze Sword

this example shows how add to group 19 IDs like 19,4688,4499 and in auctiontree.txt u can use group 19 an AH find every 3 swords

i try remake TT mats like this:

with this i made every TT mats outside any group (like for example fasion), and of course original TT mats search with low, medium, high, top classes may dont work, but for me everything work like before, so i want ask if anybody try this before, or is any other place where game can access "old" groups, i try look elements.data with sELedit, but dont find any TT mats there, i tryed this before with fashion and works fine but this one doesnt seem to work, can someone give any hint here, ty so much :)

10/27/2011 14:54 dumbfck#108

I was about to try something like this but my lunch break is over now lol...
Give this a try...
Add to the bottom of autiontree.txt:

Code:

TT by level
    TT60
        TT60 materials    60
    TT70
        TT70 materials    70
    TT80
        TT80 materials    80
    TT90
        TT90 materials    90

And add to the bottom of auctionid.txt:

Code:

15461    60    Ultimate Substance
15229    60    Piece of Skeleton
15227    70    Chientien's Edge
15228    70    Broken Drum
15230    70    Chientien's Armor Shard
15231    80    Framework of Drum
15233    80    Frenzy Lion's Skin
15235    80    Broken Shard of Gold Armor
15232    90    Soulgatherer's Tentacle
15234    90    Ancient Serpent's Skin

Those probably aren't the right TT levels for those mats but this was just to test the theory... Give it a try and let me know if it works - I'll try it when I get home later too.

Edit: I've just realised that if this works, you'll probably get some other items in those lists too as, for example, group 60 isn't unique:

Code:

60    60    ☆Viper Spear
4739    60    ☆☆Viper Spear
4552    60    ☆☆☆Viper Spear

The 60 / 70 / 80 / 90 numbers are arbitrary really, just so it was readable. You'd be better off finding some unique numbers that aren't already used as group IDs in auctionid.txt
Maybe try 600, 700 etc.

10/27/2011 18:39 Merkada#109

i try this....

NO WORK :(

edit: but original auction tree (materials-other-tt-low,mid,high,top) still works for all TT drops, so it seems game not read auctionid.txt becouse no change when i edit that...

edit2: i completly remove auctionid.txt from *.pck and auction works fine :D

Lol nice! I guess that's a redundant file then...
And yeah I just checked my suggestion too, which didn't work.
But if you got it working, then great :D

Edit: Wait a minute though.... If you remove auctionid.txt, how would it know which groups to assign to the tree? Or do you mean the standard auction works, but you don't get your custom stuff?

probably mirror of that file in other *.pck or something like that, auctiontree.txt game use bot auctionid.txt dont use, and everything in auction work normal, game still know wich ID assign to tree :)
in other words... auctionid.txt is junk file :D

edit: and it can be a server sided, wich is dont good for me :(

for the update before this one, i found the new offset myself.
but forget how :o
2BC changed to 0x74

now i try a search while count it from 0 to 10.000 and use the result converted to hex...but found no text :confused:

is there maybe a regex string for this or did they change more, wen text become colored ?

11/14/2011 16:51 dumbfck#113

Yeah I expect some stuff near the end of the offset chain probably changed a bit when they added all the coloured crap... Maybe.
By the way, 0x74 is actually the currently focused window. You'll find all your offsets will be screwed if you focus another window :P

I'm at work atm so I can't take a poke at this one, but you could perhaps take a look at my GUI mapper tool to see how windows are found and how the child controls / objects are iterated.
There will still be a constant pointer to the AH UI window in [[guiBase1]+something] but I suppose it might have moved. If my gui mapper still works at all, it'll give you that offset (the one that was previously 0x2BC).
List objects such as the AH listings, friend lists, hotkeys list, etc. are a bit of a bitch to figure out. I'd recommend trying [Only registered and activated users can see links. Click Here To Register...] if you want to explore the GUI stuff.
Alternatively, I'll try to take a look later when I get home :P

It might just be the 0xB0 part at the end... The i * 0x5D0 part points to an object for each entry in the list, 0xB0 is simply one of that object's properties. If you dig around in there, you can find all sorts of stuff, from positioning, ID, name, etc. If they've added an extra field for text colours or something then the final offsets in the chain might be different.
However, I would have thought it would make sense for them to just have the text like:
^FF2300 derp ^34FF12 blah
Like how they normally implement multicoloured text - then all the colours are handled in the final text dispatcher / display function.

11/15/2011 19:07 amineurin#114

thanks for the answer :)
hmm sounds the fault is on my side, i give it another try with antifreeze first.
before the last update all worked fine, so i thought a new offset is the problem.

11/16/2011 00:41 dumbfck#115

I seem to get asked how to find the chat message offsets (from the first post in this thread) quite a lot, so here's a tool for finding them - Just save this as an AutoIt script in your element folder and run it:

Code:

getChatOffsets()

Func getChatOffsets()
    $path = "elementclient.exe"
    $file = FileOpen($path, 16)
    $data = FileRead($file, FileGetSize($path))
    FileClose($file)
    
    $search ='.*?' & _
            '8B0D(.{8})' & _    ; /MOV ECX,DWORD PTR DS:[elementclient.0B2DE40]
            '8B4C0E.{2}' & _    ; |MOV ECX,DWORD PTR DS:[ECX+ESI+0C]
            '85C9' & _            ; |TEST ECX,ECX
            '74.{2}' & _        ; |JE SHORT elementclient.004F1586
            '8B11' & _            ; |MOV EDX,DWORD PTR DS:[ECX]
            '6A.{2}' & _        ; |PUSH 1
            'FF12' & _            ; |CALL DWORD PTR DS:[EDX]
            'A1(.{8})'            ; |MOV EAX,DWORD PTR DS:[elementclient.0B2DE4C]
    
    $matches = StringRegExp($data, $search, 2)
    
    ConsoleWrite('$chatBase = 0x'&rev($matches[1])&@CRLF)
    ConsoleWrite('$lastChatIndex = 0x'&rev($matches[2])&@CRLF)

EndFunc


Func rev($string)
    Local $all
    For $i = StringLen($string) + 1 To 1 Step -2
        $all = $all & StringMid($string, $i, 2)
    Next
    While StringLeft($all, 1) = '0'
        $all = StringTrimLeft($all, 1)
    WEnd
    Return $all
EndFunc

@amineurin - I'll take a look at the AH stuff now - been distracted the last couple of evenings with a new toy ^_^

Edit:
New AH offsets are:

Item AH page, tab delimited string for each item:
[[[[[[[[baseCall]+0x1C]+0x18]+0x8]+0x2C8]+0x208]+0x168] + i*0x800 + 0x0]

Item AH page, item IDs:
[[[[[[[[baseCall]+0x1C]+0x18]+0x8]+0x2C8]+0x208]+0x168] + i*0x800 + 0xB0]

Gold listings page, Sell list, tab delimited string for each item:
[[[[[[[[baseCall]+0x1C]+0x18]+0x8]+0x3B0]+0x208]+0x168] + i*0x800 + 0x0]

Gold listings page, Buy list, tab delimited string for each item:
[[[[[[[[baseCall]+0x1C]+0x18]+0x8]+0x3B0]+0x20C]+0x168] + i*0x800 + 0x0]

Cheers

11/17/2011 19:28 amineurin#116

ah cool, thanks a lot!
dont want to disturb you on your project with interest07 :)

so they change more then the one offset, no wonder i cant found anything.
since im not familiar like you, with finding offsets...i start after a new update to count up the old offset +1, till i find the working offset.

after those pack madness, the game got so boring.
merchanding is much harder, since most invest money in those packs.
so now i program mosttime other tools, more helpfull in reallife.

but thanks to you, i can take a look again in the ah for some cheap stuff :)

11/17/2011 20:21 dumbfck#117

Hehe no problem. Unfortunately the new offsets were changed quite a bit this time, but I didn't go through the whole process of tracing back from the beginning this time.
I'll give a brief description...
First of all, for any GUI related stuff, probably the two most useful offsets are:
[[[[[baseCall]+0x1C]+0x18]+0x08]+0x244]
and
[[[[[baseCall]+0x1C]+0x18]+0x08]+0x248]

The first one gives the base offset for GUI window you are hovering over - The second one gives the offset for which control (e.g., button / label / text box) within that window that you are hovering over.

So, for this problem, I opened the AH page then hovered my mouse over it and wrote down the offset for the main window - I also hovered over the actual auction list and wrote down the other offset for the control which is hovered over. Then, using [Only registered and activated users can see links. Click Here To Register...] I checked around guiBase1:
[[[[baseCall]+0x1C]+0x18]+0x08]
and looked for the value I wrote down.

Once I found that, I plugged the new offsets back into CE - Luckily the offset for the auction list control was still right.

Then I just looked up the offsets in CE to see where the chain broke - which was where the offset was previously 150. Then again, I just used ReClass to look where there was a suspicious looking number and hey presto - 0x168. Then I just did the same for the 0x800 value - most of the offsets around here are empty, so when you see a number like 0x1Dxxxxxxx or something, that's probably it.

That's about it. ReClass is awesome lol

03/07/2012 02:34 amineurin#118

*bump* :)

Nothing has really changed with regards to getting the message objects, except for the messageBase and lastMessageID. I'm not at home at the moment... All I can remember is that the message base offset ends in 0xAXXA98 and the last ID ends in 0xAXXAA4 :P
Start client from fresh, wait until 5 or 6 messages appear in chat window, search for number, say, between 5-15, then next search for increased number every time a new message appears in the chat window :)
All the structure sizes are the same as before.

I don't think the regex I posted somewhere in this thread works anymore for finding those two static offsets, but the above method s easy as pie.

Chat base - A57A98
last ID = A57A98 + C = A57AA4 (but dont use chat base + 0xC pointer)
