Small knowledge: the role and benefits of DLL files
As we all know, the software main program is generally exe type executable file, directly double-click it can start a software. But for DLL files, you probably don't know as much as EXE. A DLL is a "Dynamic link library" file that is an important part of a set of programs. In the development of many programs, 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

Many times, we need to compile the. cs file individually into a. dll file, which requires the CSC command to compile the. cs file into a. dll dynamic link library file. The specific steps are as follows:
Open the Command Window-> enter CMD to the console->CD c:windowsmicrosoft.netframeworkv1.1.4322
Go to the directory where the vs.net is installed-> execute the CSC command csc/target:library file.cs-> A.
Exporting from a DLL using a DEF file
A module definition (. def) file is a text file that contains one or more module statements that describe various attributes of a DLL. If you do not use the __declspec (dllexport) keyword to export a DLL's functions, the DLL requires a. def file.
The. def file must contain at least the following module definition statements:

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 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
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

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:
