This paper describes in detail the VC program in the WIN32 Environment Dynamic link library (DLL) programming principle. Share to everyone for your reference. The specific analysis is as follows:
Generally larger applications are composed of a number of modules, these modules to complete the relatively independent functions, they collaborate with each other to complete the work of the entire software system. There may be some modules that are more ve
I have read a lot of DLL programming books, but I haven't written them in actual work. the compiling of the DLL has always been in the unknown state. If you have no time in the past two days, send a blog summary!
If you are good at compiling and linking through the command line, you can refer to this blog post ).

First, DLL Overview:
The dynamic-link library (Dynamic-link Library), referred to as a DLL, is a very important component of Windows programming. There are many advantages to using DLLs:
(1) A dynamic connection using a DLL is not a copy of the library code, only the entry points and interfaces for functions are recorded in the program, the library code is load
DLL (Dynamic Link Library) learning notes (z)
Large applications are composed of many modules that complete relatively independent functions and collaborate with each other to complete the work of the entire software system. Some modules may have common functions and will still be used when constructing other software systems. When constructing a software system, if the source code of all modules is statically compiled into the entire applica

In the previous article, we introduced non-mfc dll and the MFC rule DLL. Now we will analyze in detail the last type of DLL-MFC extension DLL.
Introduction 6.1
The similarities between the MFC extension DLL and the MFC rule DLL
I believe that friends who often play Trojans will know the characteristics of some Trojans and have their favorite Trojans. However, many friends still do not know what the "DLL Trojan" has emerged in recent years. What is "DLL Trojan? What is the difference between it and a general Trojan?

I believe that friends who often play Trojan horse will know the characteristics of some Trojans, but also have their favorite Trojan, however, many friends still do not know the rise of recent years, "DLL Trojan" why things. What is a "DLL"? What's the difference between it and a typical Trojan?

1, DLL view and debugging
The core functionality of the Windows operating system is implemented in a modular way. It places a variety of related functions in the same DLL module. Therefore, each application invokes the associated system or user-defined DLL. Therefore, when you write a program, you must know how to view and debug the
Preface
Backdoor! I believe this term will not be unfamiliar to you, but it will not be harmful to you. However, as people's security awareness gradually increases, the "strong support" of anti-virus software is added ", so that traditional webshells cannot hide themselves. Anyone with a little knowledge about computers knows how to "Check ports" and "view processes" to discover some "clues ". In this way, the process and port are hidden. This article takes "
This article introduces the DLL explicit link process and the module base address relocation and module binding technology.
The first method to map a DLL to a process address space is to directly reference the functions or variables contained in the DLL in the source code. After the DLL program is run, it is implicitl
1. DLL file knowledge
DLL is short for Dynamic Link Library, meaning Dynamic Link Library. In Windows, many applications are not a complete executable file. They are divided into relatively independent dynamic link libraries, that is, DLL files, which are placed in the system. When we execute a program, the corresponding DLL
Export from DLL using def File
The module definition (. Def) file is a text file that contains one or more module statements describing various DLL attributes. If you do not use_ Declspec (dllexport)If the keyword is used to export the DLL function, the DLL needs the. Def file.
The. Def file must contain at least t
Dll link Usage Details
About Dll
Dll and Exe are binary files in PE format. Dll is equivalent to the so file in Linux.
1 Base Address and RelativeVirtual Address)
BaseAddress and Relative Virtual Address are the concepts of PE files. When a PE file is loaded, the starting Address of the process space is the base Addres
DLLIt is short for Dynamic Link Library, which is a Dynamic Link Library. DLL files are generally stored in the C: WindowsSystem directory. DLL is a library that contains code and data that can be used by multiple programs at the same time.
In Windows, many applications are not a complete executable file. They are divided into relatively independent dynamic link libraries, that is,
Summary
This article will introduce the backward compatibility of DLL, which is also known as "DLL hell. First, I will list my own research results, including the results of some other researchers. At the end of this article, I will also provide a solution to the "DLL hell" problem.
Introduction
I once accepted a task to solve a
Recently done in the Windows XP x64,vs2005 environment to do 32-bit programs to compile the work of 64-bit programs, encountered some of the 64-bit programming may encounter problems: such as inline assembly (the solution is changed to C + + code), a long type of change, The most critical issue is encountering a 64-bit process that requires calling a 32-bit DLL. Because some 32-bit DLLs do not have source code, can not be recompiled to a 64-bit
There are two ways that an application can use a DLL: One is an implicit link, the other is an explicit link. Before you use a DLL, you should first know the structure information of the functions in the DLL. Visual c++6.0 provides a small program named Dumpbin.exe in the Vc/bin directory that lets you view the function structure in a
You should also switch resources when exporting functions in an MFC extension DLL.
In a shared (dynamically linked) MFC rule DLL, before each of the exported functions need to switch resources, in the extension DLL also need, because they are dynamically linked to the MFC library, in the call to export functions, to load the corresponding resources, MFC will firs
