Auction House DPS, Left Time

[Morpheus1992]

Anyone managed to get the data shown in the list of the auction house?

I was able to get pointers to bid, min-bid, buyout, gold but i stuck for dps/armor and left time.
These values are strings and i cant find any valid pointer for them...
When mouseover-ing an item the DPS/Armor Value gets stored in an adress to... But neither for this i'm able to find any pointers.

Any tips how to do this?

I've been looking into this too. Haven't been able to find any pointers as well, for the time being i'm just scanning the memory for certain patterns.
The time left appears to be close to the bid/minbid/buyout addresses in some very weird format that I do not yet understand. It's in buyout_address-0x18 if I'm not mistaken.

This number at buyout_address - 0x18 seems to be an ID, not a timestamp.
Example:
Memory: 60618553 - Time left: 18:07 (Hour:Minute)
Memory: 60895177 - Time left: 19:09 (Hour:Minute)

Differences:
(60895177 - 60618553) = 276624
19:09 - 18:07 = 1:02 = 62 Minutes
276624 / 62 = 4461,677...

This more looks like an ID to me... anyways you can e.g. sort auctions with this ID ascending in left time.
Some examples:
22Hrs 13Min = 61931676
1Day 9Hrs = 63762079
8Hrs 38Min = 58263849
1Hrs 2Min = 57493186
<1 Min = 57462346

@Edit: Sam was faster :/

Ah yes that seems more likely :P. I have been able to extract the minbid, currentbid and buyout with their corresponding names.
I've "automated" my mouse to hover over each item and extract the name from memory.

This is how I find the address of the name tooltip
Search the memory for {0x7B, 0x43, 0x3A}. Then read a hundred bytes or so from each address and create a string from the resulting bytes
then I check the format with a regex: "{C:[^}]*}([^{]*){/C}" if it matches it's added to a list of "correct" addresses.

By reading the name from each of these addresses, then moving the mouse over another item (automatically) and then checking if the name has changed I can, more or less reliably, find the correct memory location.

You are close guys,
when you point mouse over item, info-popup displays.
all strings contained in this popup reside @ fixed location (until AH is restarted) and remain even if pupup disappears.
Strings are UTF8 encoded and null terminated. Some contain diablo's markup code which you can easily strip down with regex.
For each string there is a fixed path starting at static address, however it has 7 offsets and max offset is close to 10000 (decimal).
So you cant find this just by klicking "Find pointer for this address". You will have to track each offset backwards starting at string location.
Those paths differ only by the largest offset, there seem to be some kind of indexed structure (array) inbetween, it uses formula 0xXXX * 4
Setting read/write breakpoints and analazying assembly helps a lot.
As you move 1 or 2 offsets back from string location, you will find byte flag, which indicates if the string is visible in popup window or not.
By the way, offset path didn't change between version updates, only static address did.

I also haven't found any usefull time-info, but you can easily construct "revocation list",
so each time you look at item you put it's ID on revocation list, so next time you can detect visited items and skip them

P.S. notice that last offset to strings is in almost all cases 0. this is done by compiler so that application will be able to change strings (which may require relocation) without having to update string pointers everywhere around. i think this is called "indirect adressing".

[Woutifier]

I've actually been using a codecave to do this. It "simply" posts the contents of the popupbox to my application by using sendmessage. I have no idea how detectable this is but it's probably very easy to do so so I more or less expect to be banned any second now .

Is there a way to get the DPS & Time Left without hovering over every item? It is easy to find the string value but as soon as you research or sort by buyout the value changes. I tried getting the pointer but ran into a dead end.

Any progress?

[Melodika]

I've been doing some dry reading since a couple of days back and was hoping for a crash-course update effect on the know-hows of capturing pointers/values in D3 (auction-house only), but I think I'll need more time before I can start at all since I'm totally new to this sort of thing x_x

Any hints on how I can start on playing with the auction at least? Since there's no progress on the above said 'filter'.

[Tomed]

is it possible that dps/armor are not stored and are calculated from the items individual stats?

[TassaduqHussainAbidi]

Hi Guys I Completed the Auction House Analyzer. PM me to get the link.

[ssknight]

I'd be really interested in seeing the analyzer. PM'd.

[Tomed]

I'd be interested in seeing it too! Your inbox if full though

Thanks for the response I will make a setup and upload it on this site today.
