How to use dll files and what are dll files

Dell provides **, data, or functions to programs running under the Windows operating system. The program can open, enable, query, disable, and close the driver according to the instructions in the DLL file.

Open the installation directory of a program, and you can see some files of some dlls in it. If you double-click on it, it will prompt you next to it: If you want to see it, you can install a custom application called exescope.

After clicking to install,There's an automatic sinicization instruction in the panel that pops up,We click"Read"。 Then there will be an installation type during its installation, you can choose an installation type according to your needs, here you will select its default "Typical Installation", and then click: Next.

When installed to the installation directory of the Chinese it will prompt,If you don't want to install it to the default location,You can click Browse to select an installed file location。

dll stands for Dynamic Link Library File.

The Dynamic-Link Library (DLL) is an implementation of the concept of a shared library in Windows. The extensions of these library functions are DLL, OCX (library with ActiveX control), or DRV (legacy system driver).

The so-called dynamic link,It is to make some often shared ** (statically linked obj program library) into a dll file,When the executable file is called to the function in the DLL file,Windows operating system will load the dll file into the memory,The structure of the DLL file itself is an executable file,When the program has requirements, the function is linked。 With dynamic linking, memory waste can be significantly reduced. Static link libraries link directly to executable files.

The development process of DLLs

The original purpose of DLLs was to save disk and memory space required by the application. In a traditional, non-shared library, a portion is simply attached to the program being called. If two programs call the same subroutine, two copies of that paragraph will appear.

Conversely, many applications share the ability to slice into a dll, save it as a file on the hard disk, and use an instance in memory. The widespread use of DLLs enabled early windows to operate under tight memory conditions.

DLLs provide the usual benefits of a shared library like modularity. Modularity allows only to change the ** and data in a single dll shared by several applications without changing the application itself. This modular basic form allows for relatively compact patches and service packs for large applications such as Microsoft Office, Microsoft Visual Studio, and even Microsoft Windows itself.

The dll file is placed in the system, and when we execute a certain program, the corresponding dll file will be called. An application can use multiple dll files, and a dll file may also be used by different applications

1. First of all, if we want to open and view the DLL file, we need to install the Reflector software first, which can open and view the DLL file. After installation, you can double-click the opening icon in the installation directory to start the software.

2. After the program runs successfully, open the relector window.

3. Click on the file of the software, in the pop-up drop-down menu, click Open Assembly, this option is used to open the windows window and select the DLL file you want to view.

4. In the pop-up window, find the dll file you want to open, and the next is to select a dll file on my desktop and click the open button.

4. After opening successfully, you will see the name of the imported DLL at the end of the DLL list.

5. Click the plus icon dll in front of the name, select any method in the dll, and you can view the content of the dll file on the right side.

.DLLs are dynamic link library files, which are a common file type in Windows operating systems.

The full name of DLL is Dynamic Link Library, which is a common file type in the Windows operating system and can be called by multiple programs at the same time. In general, . .The DLL file contains some functions, data, and resources required for the program to run, which can be dynamically linked to its own memory space by the program at runtime to provide corresponding functions and services.

Shed bright sedan car. DLL files are a very important file type that is closely related to the proper functioning of operating systems and applications. In addition to the Windows operating system, other operating systems have a similar dynamic link library mechanism, such as Linux. SO file.

During program development, keystrokes and debugging, right. The understanding and use of DLL files is very important to improve the quality and efficiency of the program.
