Microsoft provides various packages for developers of third-party software. These packages contain components essential for the optimal functioning of the software. One might get the error message “msvcp140.dll missing” when trying to run their favourite game. These errors are frustrating for users. They occur because of a variety of reasons. Many amateur users do not understand the nature of these files and what they achieve. It is vital to understand what these files are before attempting to debug them. This article will focus on understanding the C Runtime Library to give users a clear picture of what .dll files achieve in the system.
What is Visual C++?
Visual C++ is a compiler provided by Microsoft for various programming languages. These languages include C, C++, C#, etc. Microsoft also provides a package called Visual C++ Redistributable to assist developers in their process. These packages are pre-installed on the operating system. However, they need to get updated regularly. Windows Update is a feature built to ensure this. Many users conduct automatic updates unintentionally. There are certain instances where the Windows Updates get turned off manually, resulting in old files. This overlook is one of the primary reasons that cause errors for users of Windows-based Operating Systems.
What is a Runtime Library?
Runtime Libraries are routines provided for the Windows Operating System. These routines perform specific functions(also known as sub-modules). They are vital for the static and dynamic linking of data and memory on an application during runtime. Without runtime libraries, this task is tough to achieve. By providing these files, Microsoft makes it easier for the developers. Developers find ease in creating applications using Visual C++ and runtime libraries. They are small files with various sub-modules combined into a library package that is pre-installed on the Operating System.
What are Dynamic Link Libraries?
Dynamic Link Libraries(also known as .dll files) are packages with elements essential for third-party software. Here are a few of these components.
- i) Classes – A class is a building block of a program. It is the blueprint for an object. With the improvement in technology across the world, Object-Oriented Languages have taken over. Classes and Objects are vital to this paradigm and have an immense impact on a program. They contain data members and member functions. Classes are a feature provided for Object-Oriented Programming Languages.
- ii) Functions – Functions are also called sub-modules. They are a small set of instructions intended to perform a specific task. A simple example of a function is a calculator. Every button in a calculator is a function as it performs a specific task.
iii) UI Resources – UI resources are indispensable to navigating an application. DLL files have these resources to ease developers in their process of creating an application. These resources might be buttons, checkboxes, etc., and help the user understand the application much better.
- iv) Miscellaneous – They also contain other elements necessary for better functioning. These are icons, images, audio, etc., that make up trivial aspects of a program.
In conclusion, C Runtime Libraries are a difficult concept to grasp for amateur computer users. However, when an error message like “msvcp140.dll missing” or “vcruntime140.dll not found” pops up on the screen, one needs to understand what the error is. These errors can be resolved with ease if there is a good understanding of the subject. It is thus vital to get a knowledge of what a runtime library is and how it affects the operating systems’ performance. This article gives an elucidation on such concepts for users to become much familiar with such terminologies.
