LEVEL: BEGINNER, Test Environment: WinXP SP3 This is a demonstration of how Opengl32 with GPA can be applied an IAT HOOK to intercept functions in a process. In this case, it is about an EXE which uses some functions from Opengl32 to create a window and render an image. ...
Level: Beginner, Test environment: WinXP SP3 This tutorial is going to teach you how to make a 'DLL wrapper'. Wrappers are own versions of known DLL's. In this case we're going to make a wrapper of a very known DLL known as PSAPI.DLL. If you don't know it then find the information somewhere XD....
An interesting example where it is intercepted, as a test, the function STRLWR. I will take no credit out of the hook, since it is about a simple patch that I googled in like 5 seconds. What I will show is a pair of pictures at the respect. How the executable was compiled, so it will be MSVCRT DLL...
This is a basic attempt to accomplish this, there is already a real big load of code about this matter... I wanted to use a different approach, I created 1 table that contains all the 256 bytes, and i used it to make the conversion.. you look at the code, better The tables ...
After a long wait C++Builder XE3 Update 1 has finally acquired the capability of building 64-bit applications. It means that developers using this tool will soon face the yet unfamiliar world of 64-bit errors. What is a 64-bit error? This is just a common error in a program. But it has one...
Introduction This article talks about how virtual table or vtable and _vptr works, with a pictorial representation. Background Virtual Table is a lookup table of function pointers used to dynamically bind the virtual functions to objects at runtime. It is not intended to be used directly...
In part I of the article about Virtual Functions, we learnt about the virtual functions, why are they needed and when to use them. This article will talk about virtual function internals and how virtual functions work in C++. Actually, virtual functions govern to an extent, how a class object is...
Virtual functions in C++ play an important role. To understand virtual function, one should be clear about the polymorphism feature of C++ language as an object oriented language. In brevity, polymorphism is the weapon through which we can identify a function call through its parameters, or...
Introduction This article talks about Initialization List in C++. Background Definition: Initialization List is another or a better approach for initializing the member variables (and base class objects) of a class upon construction of an instance of it's own.
In C, memory allocations on heap are done using following three library methods void *malloc(size_t size); void *calloc(size_t nmemb, size_t size); void *realloc(void *ptr, size_t size); Though, most commonly used is malloc() The corresponding free-ing the memory...
Talks about what is function hiding and reason behind it. Background In the example given below you would notice that the func() method has different signatures in the base and derived class. Thus its neither a case of function over-riding (which needs same function signature in base and...
Steps to integrate code into your programs This is an easy and flexible way to use bitmaps as buttons in your application, and here are the detail steps of how you can add the custom button to your application. Create a new MFC AppWizard (exe) based project and name it as BtnSample ...
This article talks about Association, Aggregation and Composition Relationships between classes with some C++ examples. Background Association is a simple structural connection or channel between classes and is a relationship where all objects have their own lifecycle and there is no owner. ...
I constantly study the Web regarding new articles on C/C++/C++11 programming. If I find them interesting, I post links to them in twitter @Code_Analysis, on Reddit /r/Viva64 and like them on StumbleUpon. If you are present on one of these websites, I invite you to follow me. You will find a lot of...
From the Bubble sort it was obvious that the sorting isn't efficient for larger list, even for a list more than 100 numbers . So there's another lot of sorting algorithms out there and this is just one of them Selection Sort Once you see the way Selection sort works, you'll wonder why one...
Had to have some days break off . So, lets move on, this time a little than practicals, but again these are more than important in solving the problems in the real world. As I said that will explain more about the different types of the data structures while we move on, here I'll explain 3 of the...
Sort the content of a linked list. Note: I had a major bug pointed out by RiOrius and is rectified now. Thanks for letting me know about it. #include <iostream> using namespace std; #define NULL 0
Oracle C++ Call Interface (OCCI) is an Application Programming Interface (API) that provides C++ applications access to data in an Oracle database. This API is a significant improvement to the Oracle Call Interface (OCI) API as far as ease of use is concerned. Engineers who have written JDBC (Java...
Just thought of having a simple example which has everything you need to know about the basics of C++. It has Inheritance, polymorphism, operator overloading, templates using friend as well as non-friend functions. #include <iostream> using namespace std; template <typename T> class Base {...
Insertion Sort like Bubble Sort & Selection Sort also uses the Array data structure. So let's see about the insertion sort, again a not-so-good sorting with some of uses of its kind and move onto a whole new brand of algorithms. Insertion Sort Like most of the sorting algorithms, this too has...
