I. Preface
Since Microsoft launched a 16-bit Windows operating system, every version of Windows operating system is dependent on functions and data in the dynamic link library (DLL, in fact, almost all content in Windows is represented by DLL in one or another form, for example, the displayed fonts and icons are stored in the gdi dll, the Windows desktop is d
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

Detailed description of VC ++ mfc dll Dynamic Link Library
Although all functions implemented by dll can be replaced by COM, dll has many advantages and is easier to create. This article will discuss how to use vc mfc to create different types of DLL and how to use them.
1. Different types of DLLYou can use VC ++ to ge
Use resources in 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
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
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
The root cause of this problem is that applications that share MFC DLL (or MFC extension DLLs) with the MFC rule DLLs always use EXE resources by default, and we have to switch the handle of the resource module, which is implemented in three ways:
Method one is used in DLL interface functions:Afx_manage_state (AfxGetStaticModuleState ());
Let's change the interface function Showdlg in the
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 "DLL
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 ).

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
This article illustrates the steps and implementation methods of C + + writing DLL dynamic link library. Share to everyone for your reference, specific as follows:
When writing C + + programs, you often need to write a class as a DLL for the client to invoke. Such a DLL can export an entire class, or it can export a method of this class.
First, export the entir
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?
First, from the DLL technology.

. NET is a language that is built on virtual machines that directly generates the intermediate language of MSIL, and then the. NET compiler JIT interprets the image as native code and delivers CPU execution. Intermediate languages are easy to decompile, so study how to protect DLL files effectively.
My general approach is: strong signature + obfuscation + encryption.Strong signatureStrong-Named assemblies ensure that your assembly is unique and not t
