About code. Mostly on C++
Recently, I stumbled across a peculiar error that I found nothing about on the web. Although I got rid of it, I didn’t figure out what the problem was. This post is merely the story of what happened. I am working on a project that contains both C++ and C# projects. The C++ ones used…
In the previous articles, we learned how to perform navigation in a Windows desktop application and how navigation events work. However, until recently, it was not possible to perform POST or GET request using custom headers or content. This feature was added in version 705.50. In this fourth article of the series, we will look in detail at how to perform POST requests with custom headers and content.
The Microsoft Build 2020 event happened this week, and, unlike all previous editions, it was a digital event only. Moreover, it was also free, so everybody could attend the 48 hours marathon. Microsoft made a lot of announcements and released various products and services for Windows, Azure, Office, Visual Studio, Edge, and more. In this post, I will summarize the things that I found the most interesting for me.
This article has been updated for the version of WebView2 that requires Microsoft Edge WebView2 Runtime 88.0.705.50 or newer. In the previous article, we learned how to create a web view and display web content in a Windows desktop application. In this third article of the series, we will look in detail at navigation and…
In the second part of this series, we will see how to use the WebView2 control in a C++ Windows desktop application. We will use a single document interface MFC application that features a toolbar where you can specify an address to navigate to and buttons to navigate back and forward as well as reloading the current page or stopping navigation.
Earlier this month, Microsoft has released the new version of its Edge browser, based on the Chromium project. The new browser works on Windows 10, Windows 8.x, and Windows 7, as well as macOS, iOS, and Android. If your application display web content, you can use the new Edge browser as the rendering engine. This is made possible through the Microsoft Edge WebView2 control, currently in developer preview. In this series, I will show how you can do this in a C++ Windows desktop application.
The .NET Core framework version 3.1 was released earlier this month, alongside with Visual Studio 2019 16.4 (which you must install in order to use .NET Core 3.1). Among the changes, it includes support for C++/CLI components that can be used with .NET Core 3.x, in Visual Studio 2019 16.4. However, not everything works out of the box. In this article, I will show how you can create and consume C++/CLI components targeting .NET Core 3.1.
The Microsoft unit testing code for managed code allows to create test methods that are executed with data automatically fetched from an external data source. This is very helpful because we can extend the data sets without modifying the test code. An external data source can be an SQL database, a CSV file or Excel document, an XML document, or anything else for which a provider for .NET exists. In this article, I will show how you can define test data using all these types of source and execute unit testing methods with it.
Back in mid-August, Microsoft released the 2nd preview of Visual Studio 2019 16.3. This is the first version of Visual Studio to support concepts from C++20 both in the compiler and the standard library (header <concepts>) without the changes made at the ISO C++ standards meeting in Cologne. These changes are available when you compile with the /std:c++latest switch.
Concepts allow performing compile-time validation of template arguments and function dispatch based on properties of types. Concepts are very useful in libraries where they can be used to impose compile-time checks on the template arguments of functions or types. For instance, a generic algorithm for sorting a container would require the container type to be sortable for the program to even compile.
In this article, I will show an example with a concept that verifies that a type T can be converted to a std::string via a to_string() function, that is either a member of the class or a free function.
The first preview version of Visual Studio 2019 is available since the beginning of December 2018. I decided to take a look to see what is different from the previous Visual Studio 2017 version. In this post, I will present some of the things that are new or changed in this new version.
