TinyOS in C#
by sirp- 0 replies
- 8.7k views
TinyOS in C# About four years ago (in the middle of the last fifteen years of writing software for money) I graduated from college. I took a round-about way through school at OIT - my four-year degree took eleven years (I actually had to make deals with four different deans to allow me to keep my credits from expiring) but it turned out OK. Some where in the middle of going to school at night we were asked in an Operating Systems class to write a "Virtual CPU and OS." More of an interpreter, we were given a description of the OS, some op-codes and an ASM-like machine language. We were to write the OS, and feed test programs into the system. It was a fun exercise and a goo…

Hi all, New here, but noticed some people here know their stuff(well close to all of them). I was hoping to find some help here. I am trying to unpack a exe which is crypted with yoda 1.3. After some searching i found CPS_UnYoda_v1.0b This did something, but not extract it. Though PEid says its yoda 1.x now instead of 1.3 But unpacking it has not worked yet, i also found Quick_Unpack_2.2.Tool But this was in russian language or something. So i have no idea if this can do it, or what error it actually gives when i try. Thanks Any helps is much appreciated.

Developing a CIL Parser
by sirp- 0 replies
- 3.8k views
The analysis of .NET libraries in [1] suggests the development of a tool for automatic contract extraction from .NET classes. The article observes that preconditions tend to be hidden under explicit exception cases. A tool leveraging this observation has been developed as part of this diploma thesis and is documented in this report. Although the chosen approach is limited to elementary cases, the application of the tool to classes ArrayList, Stack and Queue of the .NET framework [16] reveals that, in these classes, half or more of all explicit exception cases can be addressed and the corresponding preconditions are extracted by the current implementation. The report inclu…

Hi, This is something that`s been bugging me for a long time. I downloaded "Microsoft Visual C++ Express Edition", which works just fine for creating native console apps and .NET GUI apps. I cant figure out how to create a native GUI app, though. Choosing "Win32->Win32 project" is not a Win32 Form Project. Nor can i find how to create MFC projets... help?

MFMPlayer library troubles

I'm having some troubles with the mfmplayer library, seems the .lib file is no good. Writing a keygen template in assembler, when I link I get this: And all I do is, include mfmplayer.inc (which works fine ) then I include the library with includelib mfmplayer.lib and I get those 100 errors... without the lib its alright so it is something with the .lib file. Anyone a clue what could be happening? In an other project I have it works fine so I do not get what's going on here. Note: This is even before I add some code, just linking the library gives problems.

Win32 GUI - Message on Text Change

I have tried searching and downloaded various sources but I did not find one where the "key" in a Keygen is generated when the input is changed. Most of them require you to press a button. Can anyone tell me the correct Message I could use to retrieve a text change in a textbox/edit control? I already tried WM_KEYDOWN etc but they did not work. Thanks in advance!

Mono.Cecil Patch
by high6- 2 replies
- 15.7k views
Open "Mono.Cecil.Cil/CodeWriter.cs" Find "ComputeMaxStack" Add this line above it "if (!CodeWriter.FixedMaxStack)" Add field to the CodeWriter class "public static bool FixedMaxStack = false;" CodeWriter.FixedMaxStack = true; Reason for this patch is because otherwise Cecil will attempt to recompute the MaxStacks. It does not work on obfuscated code. For example ldc_i4 0 ldc_i4 0 ldc_i4 0 ldc_i4 0 br lb2 lb1: ret lb2: ldc_i4 0 ldc_i4 0 ldc_i4 0 ldc_i4 0 br lb1Cecil will compute it as 5 when it really is 8. Causing a stack overflow (InvalidProgramException) when it runs.

ASP.NET: ASM to IL compiler
by sirp- 1 reply
- 7.5k views
Lately we have been swamped with Bill Gate's new .NET vision. Once again even respectable people are crying out that C++ and assembler programmers will become extinct dinosaurs. My reaction to that is: "It's not fair!" Why are they always picking on assembler programmers? We don't do a lot of harm! Just because we like to have total freedom and like to be close to our hardware doesn't make us bad people. Go pick on someone else (like LISP programmers. I don't like them). Frankly, I was getting a little tired of this whole discussion, so I decided to do something about it - by bringing x86 assembler programming into the .NET age. Well, at least to allow ASP.NET pages to be…

BlackMagic -- Managed Memory Manipulation This is a class library to make process, thread, and memory manipulation a bit easier from a managed application. It takes care of most of the Win32 imports and a lot of the methods and tricks for you, making memory reading, writing, injection, execution, and DLL injection a snap, among a bit else. It uses ManagedFasm for JIT assembly, as well. Take a look through the code, the included examble, and the documentation. Most everything should be pretty easy and intuitive to use. If you have any questions, comments, or suggestions, please do not hesitate to post. Attached are the source, the documetation, and the binary class library…

I'd like to change it to "PUSH EBX". I have tried two APIs: Assemble() and Writememory(), but didn't success. Am I right? Could anyone write a piece of sample code for me? thanks a lot in advance.
