mfc100u.dll Error Fix

Mfc100u.dll is a part of the Microsoft Foundation Classes (MFC) which contains essential pre-written code that allows software developers to create programs with a Graphic User Interface (GUI). This allows for easier development of large applications that would take a long period of time to create using the standard Application Programming Interface (API). This provides a much easier object oriented programming interface for Windows.

The mfc100u.dll contains functions used by programs created in the Microsoft Visual Studio. Visual Studio is used to develop and create console and GUI programs along with Windows Forms applications, web sites, web applications, and web services. Visual Studio includes a code editor supporting IntelliSense (Intelligent Code Completion) as well as code re-factoring. The integrated debugger works as both a source level and machine level debugger.

IntelliSense is a context-aware code completion feature that speeds up the process of coding programs by reducing misunderstandings, typos, and other common mistakes. This is usually done through auto completion popups when typing, querying parameters of functions, and query hints related to syntax errors.

What is a DLL?

DLL (Dynamic Link Library) files contain computer code and resources that can be used by multiple programs at the same time. This uses less system memory and helps your computer system run more efficiently. DLL files give program developers the ability to reuse code to add features to several programs without the need to write new code for each program.

There are many programs that require DLL files to function properly so when one of them is damaged or missing it will cause program crashes and poor system performance.

Recommended fix if you are experiencing mfc100u.dll error messages:

DLL files are an important part of the Windows operating system and many programs rely on them to function so when one of these DLL files is damaged or missing it will cause program errors and system crashes.
