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
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
What is the relationship between lib and dll?From http://blog.sina.com.cn/s/blog_4b9b714a0100gzip.html
(1) lib is required during compilation and dll is required during runtime.If you need to complete source code compilation, it is enough to have lib.If dynamic connection is also enabled, dll is enough.In the development and debugging stages, it is best to have b
Chapter 1 Why dynamic link library (DLL)
When you mention a DLL, you will not be unfamiliar. in Windows, there are a large number of files suffixed with DLL, which are an important guarantee to ensure the normal operation and maintenance of Windows. (For example, the Win95 System directory contains more than 500 DLL fi
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

Section 2nd describes how to provide the Add function interface using the static Link Library. Next we will look at how to use the dynamic link library to implement the Add function with the same function.

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
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 some friends with computer knowledge should have heard of "dll ". Especially those who have used the Windows operating system should have had the "miserable" experience of reinstalling the system many times-no matter how careful, no driver damage, no virus intrusion, after using (installing) The software for a period of time, I fo

Large applicationsProgramThese modules are composed of many modules that complete relatively independent functions and work together to complete the work of the entire software system.

. 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.

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.
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 application EXE file, some problems will occur: one drawback is that the size of the application is increas
After uninstalling the software, more or less will be on the machine residue of some useless files, such as DLL file, very annoying. Even more troubling, there are often cases where you cannot delete these remaining DLL files. The reason is that the DLL file is being invoked by a process that is running on the current system. After knowing the reason, we can easi

MFC DLL Generally, there is a lot of knowledge about DLL in the introduction to Windows programming, while the introduction to MFC is rarely mentioned. Even if you use MFC to write a dynamic link library, it is necessary for programmers who are initially familiar with DLL to understand the background of DLL. In additio
