DLL hijacking vulnerability caused by static links of Dynamic Link Libraries
Description using QQ program xgraphic32.dll
I don't want to say so much about it. Open the question directly.

First, let's clarify the concept of the Library. The library stores binary encoding. Looking at the development path of programming technology, we can see a clear development context: code> static library> dyn
The principle of this method is to write a DLL with the same interface function as the DLL called by the original process, and then replace the original DLL with our DLL. During the replacement process, we will write functions of interest to replace the original functions, while functions of the original

Third-party libraries are often used. For example, glut, FreeType, SDL, and cegui and OSG.
Although these libraries are open-source, they are often used and are not modified.
Three things are involved: the. H. Lib. dll file.
There are three main modes:
. H +. Lib
. H +. Lib +. dll
. Dll

The most common problem about DLL is how to use the dialog box in DLL. This is a common question about how to use resources in DLL. Here we analyze and solve this problem from the Win32 DLL and mfc dll aspects.

The Non-MFC DLLs are explained in the previous section, and this section describes how to create an MFC rule DLL and how to use the MFC rule DLLs. I. Overview of MFC Rules DLLsThe concept of the MFC rules DLL is embodied in two ways: (1) It is MFC's"is MFC" means that MFC can be used inside this DLL; (2) It's a rule."is regular" means that it differs from the

In this book, the author introduces three methods to inject code into other processes, one of which is the global message hook. I first learned about global hooks from this book.We should all know that the global message hook depends on a DLL
Introduction
The DLL trap is a strange problem.
I believe that many users have such experiences. If your experiences were originally designed to run today, after you installed a new experience, all of a sudden, the power supply cannot work. This is not a problem with your hardware or application process.But the lack of design for business systems, this is usually because the new application version overwrites the shared program library (

Before starting this article, I will make a small investigation: How many friends like reboot? Answer A: I like it. I need to reboot n times every day. Answer B: I don't like it. Do not reboot for a week. If there is no accident, I believe most people will be in B's category. After all, few people will be willing to interrupt what they do and save the articles and codes being edited, then restart and wait for a few minutes before re-opening the document and code editing.

Let's talk about the method of calling the QT Dynamic link library, mainly including:1, explicit link DLL, call DLL global function, using QT Qlibrary method2. Show link DLL, call DLL class object, member function. (A call to a class member function can be implemented through an object)① uses the method of virtual func
Several precautions for creating a C/C ++ dynamic link library (dll), dynamic link library dllI. The C \ C ++ Runtime Library compilation option is a simple explanation: My dll cannot be used by others.
The Runtime Library is a very complex thing. It is a part of the dll production needs to be understood during the development process. Here we will briefly introd
1. MFC rule dll mfc rule dll can be used inside the DLL, but the interface with the application cannot be MFC.

STL cross-platform calls may encounter many exceptions. You can try it.
STL uses the template generation. When we use the template, every EXE and DLL generates their own code in the compiler, causing the static members used by the template to be not synchronized, the following is a detailed explanation of data transmission problems.
Cause analysis:One sentence ----- if any STL class uses static variables (whether directly or indirectly), do not write
We use examples to learn how to compile DLL files using gcc. The following example shows the process. There are three files in total: Hello. c. dll. H and DLL. c. hello. the content of the C file is as follows # include

Today, I installed QT and ran a simple example of QT. Then I ran the * generated in the \ debug folder *..ProgramFailed to start. "Re-installing the application may fix this problem ." This problem may be caused by the environment variable being not set. You can modify the path through: My computer> Properties> advanced> environment variable, so that the path can be modified permanently. Now, after adding "C: \ QT \ 2009.04 \ mingw \ bin; C: \ QT \ 2009.04 \ QT \ bin" to the path, you can run it

In general, to inject your own program into other processes, you must use the DLL file. This method has been discussed in the previous article. But in fact, it can be implemented without relying on DLL files. However, this method is not universal and not as flexible as DLL injection, because it needs to write the code into the "injection program". Once
Recently, someone asked in the Group how to use C language to compile DLL files (dynamic link library ).I didn't care too much about this problem or try any solution. After all, I used VB (now I use it.. Net). Creating a DLL is just a click to create an ActiveX dll project. Today, I chatted with my friends online and read several files that he showed me. I sudden
