The sample demonstrates how to use JavaScript and Visual C++ and to create app for Windows 8.1 named Bing Maps Trip Optimizer. Bing Maps Trip Optimizer uses JavaScript to define the UI and C++ to perform a computationally expensive algorithm in parallel, which can improve overall performance.
Here's what you'll learn:
- How to use Visual Studio to create a JavaScript app that references a C++ Windows Runtime component.
- How to separate JavaScript code into modules that reference the web and Windows Runtime components.
- How to create a C++ Windows Runtime component that performs computationally intensive operations.
- How to interoperate between JavaScript and C++.
- How to migrate code, such as existing COM code, for use in a Windows Store app.
This sample is written in JavaScript and C++ and requires some experience with these or similar programming languages. It also requires a Bing Maps Key in order to run.
This app is based on existing code that uses HTML and JavaScript to define the UI and a C++ ActiveX control to perform the background processing. For more info about how the sample works, how we migrated the ActiveX version of the app to a Windows Store app, and some of the considerations to make when you migrate existing JavaScript and ActiveX code to Windows 8, see Developing Bing Maps Trip Optimizer, a Windows Store app in JavaScript and C++.
To obtain an evaluation copy of Windows 8.1, go to Windows 8.1.
To obtain an evaluation copy of Microsoft Visual Studio 2013, go to Visual Studio 2013.
Note For Windows 8 app samples, download the Windows 8 app samples pack. The samples in the Windows 8 app samples pack will build and run only on Microsoft Visual Studio 2012.
