Why DLL
Let's take a look at the differences between the static library and the DLL.
Executable File generation (link phase): the former is very slow (because all symbol definitions in the library need to be linked to the EXE file ), the latter is very fast (because the latter is unsigned by the link's import and storage file)The size of the executable file: the former is very large, and the latter is very

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
interprocess communication using dynamic link libraries.Implementation methodA dynamic-link library DLL is a file that contains a series of functions and data that the application can call its functions.In general, when an application calls a function inside a DLL, the operating system maps the file image of the DLL to the address space of the process, at which
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!

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
The previous section introduced the debugging and viewing of static link libraries (dynamic link library (DLL) programming in simple terms (I). This section mainly introduces non-MFC DLL.

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?

Back door! I believe this word will not be unfamiliar to you, it's harm otherwise, but as people's awareness of security gradually enhanced, coupled with anti-virus software, "strong support" so that the traditional backdoor can not hide themselves, any little bit of computer knowledge, all know "check port" "Look at the process" in order to find some " Clues. " So, the writer of the back door adjusted the idea in time, focus on the dynamic link library, that is, the back door into a
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
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 and Exe are binary files in PE format. Dll is equivalent to the so file in Linux.

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.

Although everything that can be implemented using DLL can be implemented using COM, dll has many advantages and is easier to create.

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
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
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
