SWIG.... Never throw your old code away.

Alsalam alikom wa ra7mat Allah wa barakatoh

Today, I found a program that cought my attention, I didn't try it yet but I read a tutorial and now downloading the package...

What is it anyway?
SWIG stands for Software Interface Generator, it's a program that takes your unmanaged code (C/C++ for example) and automatically builds a wrapper library for it in a lot of other languages (C#, Perl, PHP, ...etc).

Just that simple...

// Example: file.h
class SimpleSample
void DoSomething();
This header file can be converted to SimpleSample.cs which uses pInvoke to call the underlying C++ Code...

SWIG is a fully function C++ Compiler. It can also build up a proxy class for a collection of your C++ Functions/Classes. It's just nice and powerful (I hope it functions like how it sounds)

Moreover, it's Open Source, works with a GNU CSharp Compiler (in case you want to output a .NET Library) it can also work with many other CSharp Compilers (if you wish to change)

I'm going to try it (when I manage to connect to the wireless service at the faculty again In Shaa Allah...) and I'll be posting my little experience with it In Shaa Allah...

There are a lot of ideas over there... work hard, and you will get one, then you will have to work harder to get it done... Just start...

Exploiting Double Free Vulnerabilities...

Alsalam alikom wa ra7mat Allah wa barakatoh

Huh!! that's what I said when I first saw that title... but let me explain...

Double Free means that you try to free a pointer two times (which is logically can't work).
Actually windows SP2 and later (even Vista) this can be done (in somehow) and can actually corrupt the heap (Vista will shout at your face if u did) and that can make you able to use and browse the heap as you want..

Facts to know about how Windows frees your pointers:
- There is something called Lookaside buffer (fast access, small size) and another thing is FreeList(slower access, the whole memory).
- Chunk is an object of the DataStructure that holds mainly 2 things: pointer to where the next free Chunk is and pointer to the previous free one (think about it like a node in a linked list)
- The first 4 bytes of the Chunk is the BLink (BackLink) and the second 4 bytes is the FLink
- delete ptr1;
delete ptr2;
Windows takes your Chunk (for ptr1) and puts it in the Lookaside s…

Windows7 adds Math Input Panel

Alsalam alikom wa ra7mat Allah wa barakatoh…I was reading a windows team post about Input Panels improvements in Windows7 [here]. When at the end I saw a very interesting –intuitive if you wish- new thing… which is, as you guessed, the Math Input Panel…Yes, that crappy font is mine… I “drew” that by mouse as I don’t have a tablet pen/pc.You can then paste it directly into word and it’ll recognize it as an editable equation…During my tests, the output panel (the top part) hanged, but I liked that the drawing panel was still responsive and I could still write/erase… till the top one started to respond again…One other thing to know, after you click Insert (that button down there) it copies the equation in MathML [Wikipedia link] format.. which is a standard way of representing equations and hence any application that recognizes the format can insert it not as an image but as a nice editable equation…If you think it recognized something wrong, you can click “Select and Correct” then draw …

Visual Studio 2008 Not saving changes or project properties?

Alsalam alikom wa ra7mat Allah wa barakatoh (Peace upon you)I’ve recently ran into problems with VS 2008. Summarized here:When you try to edit the project properties (specially C++ projects) you are faced with a little nice message saying “Exception from HRESULT: 0xF9F0F308”. Sometimes when you are editing a file (specially large ones), VS doesn’t recognize you’ve made changes (ie doesn’t display that ‘*’ in the files tabs) hence, when you save, nothing actually gets saved. For those 2 problems, a friend explained the problem and a work around (till they officially release a fix)…Open up a Visual Studio 2008 Command Prompt Run cd "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE" Make a backup copy of devenv.exe in case something does not work right.
ie. copy devenv.exe devenv.exe.bak Run editbin /largeaddressaware:no devenv.exe Happy VSing… :)
