Re: Hooking D3Device8 by replacing the VTable fails. Info needed.

Hello Paul

Thanks for your reply. I think I have to take some time to sit down and
read that carefully.

The end of the table is obvious if you have symbols :). Many of the tables
have addresses where the first two or three hex digits are the same. Often
there table is followed by zeros or a value wildly different than the what
you would expect for an address. I also check that the value is within the
range the of the loaded module the table is found within. There a few
occasions where one table is followed by another but I can't remember with
respect to what.

If the values in the table point to the beginning of a function then they
are not stored variables. don't move the tables, I copy them to a array
of
pointers (pointers so the symbols will be displayed). I copy the entire
table and have had no ill effects except in DirectX 7 where a couple of
calls were hard wired; a bug in my opinion. Putting the table into an
array
of pointers will spit out all of the function names but you need to use
symbols.

Private in my jargon only means the public interface supplied in the
h-files
does not expose the entire table. I would only guess that internally they
can overide the calls the public interface does not expose. (I do :))

One of the calls in the hidden area is used to detect when the resource
count goes to zero. Then it destroys the DirectX device, deletes the
memory
for it, and decrements the resource count so the return from
device->Release() returns zero. If you create any resources of your own
the
device destruction call will never take place and most games will raise an
exception.

I like assembler too, but getting the table below is easy in C.

Here is the DirectX 9.0C Vtable. It is offset one count. I hope that helps
your curiosity :).

QueryInterface is really at index zero.
I believe from the include file that This is the last public function:
STDMETHOD(CreateQuery)(THIS_ D3DQUERYTYPE Type,IDirect3DQuery9** ppQuery)
PURE;
All functions after that are no visible unless we cheat :).

I actually vector the hidden scalar deleting destructor to me.

CreateQuery is at 0x77 here and 0x76 in the actual table.

Hello Paul,

If you load the symbols for DX8 you should be able to look at the
addresses and see what those functions are.

Alas, I'm not using C... for my experiments, but assembly (and have no
(easy) way of loading or looking at those symbols).

The end of the table is kind of obvious.

Well, that is (partly) why I posted my question : looking at the values
in
that VTable I could not find such an obvious end, nor did I google any
information in that regard.

Allso, I was 'afraid' that some of those values could be stored
variables
(and moving them around would wreak havock on the DirectX, and by
association my own system).

If you are going to hook the D3D device table that way then you
will have to hook calls like BeginStateBlock and EndStateBlock

Thanks for this, it gives me something to google for.

If you store the table in an array of pointers then the symbols will
work there to and you can set a watch on your table and see what
all of the private calls are. It is kind of neat to look at it.

:-) That is partly why I posted the question to. Plain curiosity to
whats
going on.

A question though : why are those private calls part of the VTable, and
not
simply direct calls to their own code ?

In a class some functions are public and some are private.

If you load the symbols for DX8 you should be able to look at the
addresses
and see what those functions are.

If you are going to hook the D3D device table that way then you will
have
to
hook calls like BeginStateBlock and EndStateBlock . BeginStateblock
will
reset the device table so you have to make the code return control back
to
you so you can reset your modified addresses. In other words you have
to
make the call.

If you change the vtable pointer to your local table then you need to
copy
all of the private pointers as well, there is no half way measure. The
end
of the table is kind of obvious.
