Although I'm not sure if this is up-to-date and correct. Result := ((AType as TRttiInstanceType).VmtSize - (ABaseType as TRttiInstanceType).VmtSize) div SizeOf(Pointer) Īnd: When using Jedi there is a function in JclSysUtils called GetVirtualMethodCount. Here is an approach with a variable base class provided: function GetVirtualMethodCountMinusBase(AClass: TClass ABaseClass: TClass): Integer ĪBaseType := AContext.GetType(ABaseClass) The reports are based on individual state reports on traffic data counts. Data for this indicator come from the Federal Highway Administration (FHWA), 2011 Highway Statistics. But it is possible to subtract all entries from a given base class, e.g. Vehicle miles traveled (VMT) per capita is calculated as the total annual miles of vehicle travel divided by the total population in a state or in an urbanized area. Including the ones from TObject at negative offsets. to calculate the address of vmt I am doing base address of our process + virtual address. I made a simple application with 2 classes and virtual functions, how it looks in ida. This will however include all entries inherited from the base class(es) too. my vmt hook doesn't override specific function pointers, what i'm trying to do is find the vmt > make a copy of it > switch the vmt pointers so my custom vmt gets called. Result := (AType as TRttiInstanceType).VmtSize div SizeOf(Pointer) So using VmtSize and a VMT entry being a Pointer function GetVirtualMethodCount(AClass: TClass): Integer TRttiInstanceType knows the VmtSize of the associated class. At the end of the hooked function, I am trying to call the original function to preserve the original behavior.A way to do this without much actual knowledge of the VMT structure, and hence less prone to breaking when the VMT structure changes again, is using the Rtti for this. In the hooked function, I am just outputting a debug line with the trampoline address. Next, I hooked up the function as was shown in the example project, substituting all x32 references with 圆4. I compiled the project with the PDB file, which helped me find the RVA of the function of interest using 圆4dbg. I was going to continue fixing it up nice and then make a formal release but I'm busy with other stuff now, so here you go. Here is a little d3d9 endscene hook template I made for CSS, same thing for CSGO tho. I am trying to use polyhook2 to detour a function from an 圆4 Unreal Engine 4 project. Alot of people agree that VMT table hooking of EndScene is something that gets you banned, do a regular detour instead at the minimum. Cannot construct instance of class name although at least on creator exists. MessageBox(NULL, L"hook error", L"HOOKED", 0) No tutorial is necessary for a VMT hook, all you do is overwrite a 4 or 8. std::cout << "hook success." << std::endl MessageBox(NULL, L"hook success", L"HOOKED", 0) MessageBox(NULL, L"IN HOOK", L"HOOK", 0) PLH::IatHook hook("wininet.dll", "InternetConnectW", (uint64_t)&hkInternetConnectW, (uint64_t*)&oInterConnectWFunc, L"") PLH::IatHook hook("kernel32.dll", "GetCurrentThreadId", (char )&hkGetCurrentThreadId, (uint64_t)&oGetCurrentThreadID, L"") PLH::CapstoneDisassembler dis(PLH::Mode::圆4) SlimDX stores the native IDirect3DDevice9 interface in the Device class. NOINLINE DWORD _stdcall hkGetCurrentThreadId() oInterConnectWFunc ( hInternet, url, nServerPort, lpszUserName, lpszPassword, dwService, dwFlags, dwContext) Can anyone give me insight on how to find the Driect3D device VMT table either.
