Modernizing C++ MFC Applications

At Leaning Technologies, we understand the challenges associated with modernizing C++ MFC (Modern Foundation Classes) applications. We offer a comprehensive solution that minimizes technical risk, accelerates the timeline, and preserves your valuable intellectual property and team skills. With extensive experience in modernization using Cheerp, a state-of-the-art C++ to WebAssembly compiler, we provide a three-pronged approach to transform your legacy applications into modern, efficient, and web-compatible solutions.

Our Three-Pronged Approach

1. Manual Re-design and UI Implementation

We begin by re-designing and implementing the application’s user interface (UI) using HTML5-native technologies such as React, Angular, or Vue.js. This step ensures that your application’s front-end is fully modern and responsive.

2. Automatic Porting with Cheerp

Our expertise lies in leveraging Cheerp, a powerful C++ to WebAssembly compiler. We automatically port your C++ code to WebAssembly, making the transition to the web seamless. This process significantly reduces technical complexity and accelerates the modernization effort.

3. Adaptation to Web APIs

The final step involves adapting any remaining native or system-level code to utilize modern Web APIs. This adaptation ensures that your application can interact seamlessly with web-based services and data sources.

Advantages of Our Approach

1. Reduced Technical Risk

By preserving the most critical parts of your application’s code, we mitigate the technical risk associated with modernization. Your application will continue to perform its core functions as it did in the original codebase, ensuring reliability and consistency.

2. Faster Timeline

Our approach reduces the technical effort required by 70-80%, thanks to automatic porting and code preservation. This means you can bring your modernized application to market faster, gaining a competitive edge.

3. Preserve Intellectual Property and Team Skills

We understand the value of your investment in intellectual property, knowledge, and team skills. Our approach ensures that your C++ codebase is preserved almost in full, along with the expertise of your existing team.

4. Proven Expertise

Leaning Technologies has successfully modernized millions of lines of code, spanning applications of various complexities, including Enterprise solutions, Video Games, and Engineering applications. Our track record speaks to our expertise and commitment to delivering reliable modernization solutions.
