[C# + Win32] Memory Reading Class Example

[amadmonk]

You've gotta be kidding me. I wrote all that ****ing code and there's a single function in the framework to do it? That's what I get for not searching. FML.

I'll change that and add string reading in just a second. Thanks.

Don't feel bad, I did the same thing. The BCL is vast and wide, and few know all of its shoals and eddies.

I'm in a poetic mood today for some reason...

Apoc, or anyone, where might I find these "easy and clean" ways of doing math on IntPtrs?

Apoc why are you being so rude to Joe? He just complimented the community and tried to contribute with somthing he obviously finds as a hobby, and your giving him the gesture that MMOwned is a non-helping flaming website.

If you consider constructive criticism as rude, so be it.

Wow you guys are a bit retarded.

1) Win32 vs .NET API is nearly as fast either way. (If you don't include the extra checks in the .NET API [which 99% of the time, prevent you from making stupid mistakes])
2) That memory reading class is pretty ugly. And quite a waste of space.
2a) Your naming conventions suck. Period. Please go read the MS naming conventions for C#.
2b) Your code will be a huge pain in the ass to maintain. Even on small code-bases. Learn code-reuse.
2c) Use proper .NET code structures. Those include; the Encoding class. (Support for UTF8 and byte-length availability) The Marshal class. (Proper use, not Marshal.SizeOf(x), use sizeof(x) for those)

Last but not least; USE A GOD DAMNED INTPTR! NOT A ****ING INT! IntPtr is the equivalent to any type of pointer in the unmanaged world. (That includes handles) Seriously, this code is just plain ugly as sin.

Phear my leeb and uber-fast c++ codenz.

Hi, you must be new here. Please jump off a bridge.

I'd personally consider "USE A ****ING INTPTR" to be rude, but you're the one with the banhammer.

Also, you must have missed my question.

uint ptr = (uint)myIntPtr.ToInt64(); // Or.... (uint)myIntPtr;

Then go play with the 'ptr' variable instead. It's hard, I know.

Sorry Apoc. I mistook you for meaning something that was actually clean looking and didn't involve casting twice (best case scenario).

Why are you afraid of fundamental language concepts?

Casts scare me irl.

Tbh, first read I thought you said cats. lol.

Im in the middle of writing my own memory reading/writing class at the moment, yes I could use BlackMagic but I prefer the satisfaction and experience of doing it myself

@Apoc, if it's ok, could I use your code on page 1 as inspiration for some aspects of my own? no copy and pasting of course just ideas. Thanks.

fixed a typo for u

You can c/p it if you want. Just don't claim you wrote it

I had to change this code

case TypeCode.Object:
    // Double check this. It *should* work. But may not. Untested
    GCHandle handle = GCHandle.Alloc(buffer, GCHandleType.Pinned);
    Marshal.PtrToStructure((handle.AddrOfPinnedObject(), ret);
    handle.Free();
    break;

to this

case TypeCode.Object:
    // Double check this. It *should* work. But may not. Untested
    GCHandle handle = GCHandle.Alloc(buffer, GCHandleType.Pinned);
    ret = Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(T));         
    handle.Free();
    break;

The PtrToStructure method was throwing an exception and complaining that "The structure must not be a value class." with your code.

Thanks for sharing your memory reading class by the way.

Oops :S

Forgot about that :P
