[Release][C#]WhiteMagic - Injected .NET Helper Library

[adaephon]

Yeh, I understand that. As I said, I was wanting to use this check for a personal project, not in conjunction with White Magic. I just looked at White Magic to see if it was only my issue or not.

If you're interested, I got around it using

structure.GetType().StructLayoutAttribute == LayoutKind.Auto
or
structure.GetType().StructLayoutAttribute.IsDefaultAttribute()

I'm guessing the GetCustomAttributes doesn't work because all classes/structs have the StructLayoutAttribute (it's just usually default value of Auto) and maybe it's not considered Custom.

That's actually a very good point.

Thanks for the heads up. (Ya learn something new every day!)

Apoc, this is very well written although, because I'm anal, I've located a few functions you can safely convert to LINQ, the bottom function I just added in the ?? operator.

private static bool DataCompare(byte[] data, int offset, byte[] byteMask, string mask)
        {
            // Only check for 'x' mismatches. As we'll assume anything else is a wildcard.
            return !mask.Where((t, i) => t == 'x' && byteMask[i] != data[i + offset]).Any();
        }

        public T Read<T>(params IntPtr[] addresses)
        {
            return Read<T>(addresses.Select(ptr => (ADDR) ptr.ToInt32()).ToArray());
        }

        public static Magic Instance
        {
            get { return _instance ?? (_instance = new Magic()); }
        }

Don't mean to nit-pick here.

Needless to say, pattern matching with a linq query is much slower than a hard coded loop because those lambdas aren't inlined.
Also you are changing the expected behaviour of Read<T>(params IntPtr[]), if I interpreted it in a way it would compile.

[Apoc]

1) You just broke Read<T>(params IntPtr[]). Thats not how it works.
2) I'm well aware that I could use LINQ. However, LINQ is also much slower due to the compiler not being able to inline any of it. (It can't inline delegates)
3) Really?

If you're going to nitpick and assume that ReSharper knows-all, at least understand that R# isn't always correct in terms of performance.

Hi,

Could you re-upload your library ?
Havn't messed with Wow code for at least 2 years and I'd like to change that

Thanks

I lol'd because I was going to say the same thing. Resharper is good, but don't post on here with a resharper cosmetic change and assume someone like Apoc hasn't already noted that. Being that it is a 2 year necro and I hadn't already said it,Good work on the library Apoc!

Thanks. Fact is though, this library is actually quite bad.

I've recently written "GreyMagic", which is an in/out of process wrapper. It absolutely shits on WhiteMagic in terms of performance. (Also substantially faster than other out of process libs as well). I may end up releasing it sometime soon.

Ah that sounds great. I currently use WhiteMagic in cleancore (cach and mic library) and hadn't actually looked much into the implementation. I'm sure plenty of people would be interested in it (myself for sure). Pretty much learned a lot of in-process work from WhiteMagic. Also +points for your original naming scheme

I just can't resist to say... I love that naming scheme too!

Looking forward to it very much.

When I call m.Read<IntPtr>(0xABF47C, 0x2800), 42) I'm getting an exception raised that says: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

I'm using the code from the example and only changed the EndScene offsets to the ones for the current version. I'm calling a method in my C# .dll from an injected C++ bootstrap DLL using ExecuteInDefaultAppDomain, which should mean I'm in-process, right? Am I doing something wrong?

Didn't WoW already have ASLR at the time he wrote that example?
