Although everything that can be implemented using DLL can be implemented using COM, dll has many advantages and is easier to create. This article will discuss how to use MFC to create different types of DLL and how to use them.1. Different types of DLLYou can use MFC to generate two types of DLL: MFC extension
There are two kinds of libraries:One is that Lib contains the information (ingress) of the DLL file in which the function resides and the location of the function in the file, which is provided by the DLL that is loaded in the process space by the runtime, called the dynamic link library.One is that Lib contains the function code itself, which is added directly to the program at compile time, called static
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
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.

[Reprint] Parsing DLL files in Windows---interpretation of classic DLLsIn the Windows world, there are countless blocks of active continents, and they all have a common name-the dynamic link library. Now walk into these magical activities of the mainland and find out their long hidden secrets!First glimpse of the doorway: the cornerstone of WindowsOpen a system directory casually, you can see a lot of extensions D
DLL (Dynamic Link Library), you can simply think of a DLL as a repository that provides you with variables, functions, or classes that you can use directly. In the history of the warehouse has experienced the "No library-static link library-dynamic link library" era.Both static and dynamic link libraries are shared code, and if you use a static link library, the instructions in Lib are included directly in
Advantages of DLLSimply put, DLLs have several advantages:1) Save memory. The same software module, if reused in the form of source code, is compiled into different executable programs, and the binaries of these modules are repeatedly loaded into memory when the EXE is run. If you use a DLL, it is loaded only once in memory, and all processes that use the DLL share this block of memory (of course, a global

Calling a DLL is easier than writing a DLL. First, we will introduce static call methods. Later we will introduce dynamic call methods and compare them. Let's take a static call example first.

(Compiled using VC. CPP file or. the C file will get the target file. OBJ. After compilation, the link program links the target file to the final output file according to the specified requirements. LIB /. dll /. EXE.
Compared with the dynamic library, the static library does not have entry functions and cannot be executed independently or dynamically linked. Once linked to the target file, the code segment/Data Segment of the static library will be

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
Based on my learning problems, This article focuses on the following issues:
1. dll related concepts
2. Use of dynamic non-mfc dll in VC ++
3. Application of macro in DLL export function and import function declaration

You can simply regard a DLL as
What is a DLL (dynamic link library)?
A DLL is a library that contains code and data that can be used by multiple programs at the same time. For example, in the Windows operating system, the COMDLG32 DLL performs common functions related to dialog boxes. Therefore, each program can use the functionality contained in the DLL
4.2 Declaring the exported function
There are two ways to declare a function in a DLL: one for the 4.1-section example, plus __declspec (dllexport) in the function declaration, which is no longer illustrated here; another way is to use the module definition (. def) file declaration,. The DEF file provides the linker with information about the exported, attributes, and other aspects of the linked program.
The following code shows how to do the same.

1. Introduction to DLLDLL, dynamic link library, or dynamic link library is a set of modules that can be shared by other applications. As an executable file of the shared function library, DLL encapsulates one or more compiled and linked functions. Multiple processes can use one DLL at a time and share a copy of the DLL in the memory.
