How Many Categories of DLL Files Are There?

When you think of DLL files, you probably know the categories available. The categories include Static linking, Resource DLLs, Exports, and Imports. However, before you choose the right one, you need to know what type of DLL you have. Read on to learn more about each category and how it works.

Static linking

DLL files are libraries containing reusable code and shared between multiple processes. They are used for the dynamic loading of applications and to share components and libraries. A DLL file contains many different classes, functions, and variables that are part of an application. This file type is referred to as a dynamic library and is often found in Windows systems.

DLL files are tiny programs that a more extensive program can load whenever it needs to use a specific feature or function. These files may not perform the core functions of the original program but may help it communicate with a device or process a document. Device drivers are examples of that support specific device operations.

While DLL files are integral to Windows, they have several drawbacks. One such drawback is what’s called DLL hell. These files can cause the installation of hundreds or even thousands of files on a system. As a result, Microsoft has promoted virtualization-based solutions, which offer better isolation between applications. Another solution is to use side-by-side assembly. This type of link allows multiple applications to use the same DLL. Additionally, these types of DLLs can be modified without changing the program.


DLL files also called shared libraries, are small, reusable programs that multiple software applications can use. They can be read-only, executable, or contain libraries and other code. They can also contain data, images, and other items. To run, DLL files need to be called by another executable file.

Another everyday use of DLLs is to modularize programs. For example, an accounting program might sell modules loaded into the main program at runtime. Having separate modules makes the load time faster. It’s also easier to apply updates to individual modules rather than the entire program. For example, a payroll program might change tax rates yearly, so updating DLL files would be less complicated than rebuilding the program.


Imports of DLL files are used in C++ to create dynamic libraries, allowing programs to use a library of functions and data without having to write the code themselves. A DLL is a library of functions and data that many different programs can use simultaneously, and the OS creates a link path for each program to use when it needs to reference a DLL file. Different programs use different calling conventions for DLLs, so the library’s name should be unique for each program.

When using a DLL, the calling executable file should include a header containing the exported functions and classes. Function calls to these exported functions and data are the same as any other function call in C. The calling executable file should link with the import library or call its LoadLibrary () function to load the DLL.

When using the -S command-line option, you must specify the command-line options to pass to the assembler. By default, this option only takes one argument. If you are passing multiple arguments, it is essential to include double quotes. Another option is -e. The -e option specifies the DLL’s name should be stored in the. Def file.

Resource DLLs

A DLL file is a collection of small programs that a more extensive program loads when it needs to do a specific task. These programs may not be core to the original program, but they may help it to communicate with a device or process a document. Some DLL files are device drivers that perform a specific function on a specific device. They are used to make a program easier to use and operate.

Most users have at least heard of DLL files, and they are familiar with their use. However, they often overlook the possibility of malicious DLL files. When this happens, a user may think they have a virus. They may try reinstalling the program or even updating it. However, it is always better to avoid modifying DLL files.


DLL files are separated into two basic categories: executable and non-executable. The executable section contains the code to run programs. The non-executable portion is the data. The data portion is used to load programs and perform other tasks. Each category has different attributes and is used to perform different functions.

There are two main categories of DLL files: executable and read-only. The executable section contains the program code, while the non-executable portion contains data. While DLL files aren’t executable, they still have various functions, classes, and variables.
