hi, this program is supposed to output the pids & names of all running processes: PROCESSENTRY32 pe32; HANDLE procsnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 ); pe32.dwSize = sizeof(PROCESSENTRY32); Process32First(procsnap, &pe32); while(Process32Next(procsnap, &pe32)) { printf( "PID: %d [%s]\n", pe32.th32ProcessID, pe32.szExeFile); } However, only the first char of the process name is printed. The PROCESSENTRY32 structure can be found here: />http://msdn.microsoft.com/en-us/library/ms684839%28v=VS.85%29.aspx

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
by F0X- 9 replies

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
by Unbekannt1- 5 replies

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
- 15.6k 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…

Hooking to defeat hardware breakpoints
by FlySky- 3 replies
- 7.2k views
Hey guys, New to the forum and wondering the following. Been doing reversing for a while now and recently jumped into unpacking. What I am facing atm is that a lot of packers are detecting hardware breakpoints. I am currently on Windows 7 64 bit version and none of the Ollydbg plugins are working for me, so I started looking in writing my own hooks. Been programming / coding for a couple of years in assembly and I am hoping you guys could push me in the right direction about hooking to prevent hardware breakpoint detection. The hardware breakpoint detection is accessed and controlled from an exception handler. So I read up about it and found out an area to hook could be h…
