Why Is My C Application Throwing an

Running into the "MSVCP140.dll Missing" Conundrum

Encountering the "MSVCP140.dll missing" error while attempting to execute an application in C can be perplexing. This issue stems from the absence of a crucial runtime dynamic-link library (DLL) required for the program to run.

Why Does It Happen?

When developing in C , runtime libraries provide critical functions that are not built into the programming language. The Microsoft Visual C Redistributable Package, which contains MSVCP140.dll, is one such library. If this package is not installed on the user's computer, the application will fail to locate the DLL and trigger the missing file error.

Resolving the Issue

There are two primary methods to address this problem:

Install the Runtime Library: Direct your friend to download and install the Microsoft Visual C Redistributable Package corresponding to the version of Visual Studio used to compile the program. This will provide the missing MSVCP140.dll file.
Static Linking: Alternatively, you can compile your application with static linking. In Visual Studio, navigate to Project > Properties > Configuration Properties > C/C > Code Generation. Choose "/MTd" for debug mode and "/MT" for release mode for the "runtime library" setting. This approach embeds the runtime library into the application, making it independent of any external DLLs.

By implementing either of these solutions, you can ensure that the MSVCP140.dll is available, enabling your friends to execute your C program flawlessly.

C# vs. C : Learning Curves and Developer ExperienceApr 18, 2025 am 12:13 AM

There are significant differences in the learning curves of C# and C and developer experience. 1) The learning curve of C# is relatively flat and is suitable for rapid development and enterprise-level applications. 2) The learning curve of C is steep and is suitable for high-performance and low-level control scenarios.

C# vs. C : Object-Oriented Programming and FeaturesApr 17, 2025 am 12:02 AM

There are significant differences in how C# and C implement and features in object-oriented programming (OOP). 1) The class definition and syntax of C# are more concise and support advanced features such as LINQ. 2) C provides finer granular control, suitable for system programming and high performance needs. Both have their own advantages, and the choice should be based on the specific application scenario.

From XML to C : Data Transformation and ManipulationApr 16, 2025 am 12:08 AM

Converting from XML to C and performing data operations can be achieved through the following steps: 1) parsing XML files using tinyxml2 library, 2) mapping data into C's data structure, 3) using C standard library such as std::vector for data operations. Through these steps, data converted from XML can be processed and manipulated efficiently.

C# vs. C : Memory Management and Garbage CollectionApr 15, 2025 am 12:16 AM

C# uses automatic garbage collection mechanism, while C uses manual memory management. 1. C#'s garbage collector automatically manages memory to reduce the risk of memory leakage, but may lead to performance degradation. 2.C provides flexible memory control, suitable for applications that require fine management, but should be handled with caution to avoid memory leakage.

Beyond the Hype: Assessing the Relevance of C TodayApr 14, 2025 am 12:01 AM

C still has important relevance in modern programming. 1) High performance and direct hardware operation capabilities make it the first choice in the fields of game development, embedded systems and high-performance computing. 2) Rich programming paradigms and modern features such as smart pointers and template programming enhance its flexibility and efficiency. Although the learning curve is steep, its powerful capabilities make it still important in today's programming ecosystem.
