Unwrapping WinUI3 for C++

Posted on April 8, 2022April 8, 2022 by Marius Bancila

The Windows UI Library 3, known shortly as WinUI 3, is a native UI framework that ships with the Windows App SDK. This is an SDK complementary to the Windows SDK, WPF, WinForms, and Win32. It provides a new unified set of APIs and tools that can be used to develop desktop apps on Windows 11 (as well as downwards to Windows 10, version 1809). I decided to have a look at what this framework provides and this post is written as I am trying it. To evaluate it, I’ll try to build a small application that does conversion between Celsius and Fahrenheit degrees as you type in a field.

You Chemical Name – My First Windows Store App

Posted on November 15, 2013 by Marius Bancila

My first Windows Store app (for Window 8.1) is now available in Windows Store. It’s called Your Chemical Name and shows names (and text) using chemical elements symbols in the Breaking Bad style. The application allows to: customize the appearance of text, colors, background customize the position of the text on the background save image…

Working with the Settings Charm for Windows 8.1 Store Applications

Posted on November 13, 2013 by Marius Bancila

Windows 8 features a Settings charm to display both application (the top part) and system (the bottom part) settings (you get it from swiping from the side of the screen). The system provides two entry points, Permissions and Rate and Review, the later only for applications installed through the store. You can customize the settings…

Render the screen of a Windows Store App to a bitmap in Windows 8.1

Posted on November 5, 2013November 5, 2013 by Marius Bancila

In WPF, Silverlight and Windows Phone it is possible to render a visual object into a bitmap using the RenderTargetBitmap. This functionality, that I find pretty basic, was not available for Windows Store applications. Fortunately, Windows 8.1 provides that functionality for Windows Store applications too, through the same RenderTargetBitmap class. There are some limitations though:…

Things I like about native development with C++/CX

Posted on November 12, 2011November 14, 2011 by Marius Bancila

Visual Studio 11 brings many new things for native development, including support for new features from C++11 (unfortunately not all), or ability to write Metro apps with C++/CX including modeling the UI with XAML. In this post I will talk a bit about three favorite features that I noticed immediately after trying VS11 from Windows…

WinRT and winmd Files

Posted on October 30, 2011October 30, 2011 by Marius Bancila

If you tried the Win8 Developer Preview and built WinRT components (native or managed) you noticed the .winmd files. The name stands for Windows Meta Data and the format of these files is the same used by the .NET framework for the CLI, i.e. ECMA-335. That means you can actually read these files with a…

C++, WinRT and Partial Classes

Posted on October 13, 2011November 23, 2012 by Marius Bancila

Partial classes are finally available to C++. Sort of. It’s not part of the new C++11 standard, it’s part of the C++/CX language developed by Microsoft for targeting WinRT on Windows 8. Partial classes mean that you can define a class spanned across several files. Why is this great? Because it allows developers and automatic…

Windows Runtime

Posted on September 15, 2011September 16, 2011 by Marius Bancila

Windows Runtime, or shortly WinRT, is a new runtime (siting on top of the Windows kernel) that allows developers to write Metro style applications for Windows 8, using a variety of languages including C/C++, C#, VB.NET or JavaScript/HTML5. Microsoft has started rolling out information about Windows 8 and the new runtime at BUILD. WinRT is…
