A Windows Forms application is an event-driven application supported by Microsoft's .NET Framework. Unlike a batch program, it spends most of its time simply waiting for the user to do something, such as fill in a text box or click a button. The code for the application can be written in a .NET programming language such as C# or Visual Basic.
An event requires an accompanied event handler that is made from a special delegate that in a platform specific library like in Windows Presentation Foundation and Windows Forms usually takes two parameters: sender and the event arguments. The type of the event argument-object derive from the EventArgs class that is a part of the CLI base library.
Each button click or shortcut key results in a new command/event object. Some implementations add more information to the command/event object as it is being passed from one object (e.g. CopyCommand) to another (e.g. document section). Other implementations put command/event objects in other event objects (like a box inside a bigger box) as ...
The XAML file defines the layout, which in this example is a vertical collection of controls - a textblock outlining instructions to the user, a textbox for the user to type their name, a button to submit, and a results text block. When the button is clicked, the method SubmitButton_Click is called, which is defined in the .xaml.cs file. This ...
The following simple examples compare VB and VB.NET syntax. They assume that the developer has created a form, placed a button on it and has associated the subroutines demonstrated in each example with the click event handler of the mentioned button. Each example creates a "Hello, World" message box after the button on the form is clicked.
Microsoft first used the name C# in 1988 for a variant of the C language designed for incremental compilation. [37] That project was not completed, and the name was later reused. C-sharp musical note. The name "C sharp" was inspired by the musical notation whereby a sharp symbol indicates that the written note should be made a semitone higher ...
The name, "Blazor", as explained by Steve Sanderson, is a portmanteau of the words "Browser" and "Razor". (from the Razor syntax being used) Blazor got admitted as an official open-source project by Microsoft, and in 2018, as part of .NET Core 3.1, Blazor Server was released to the public.
Nemerle's most notable feature is the ability to mix styles of programming that are object-oriented and functional. Programs may be structured using object-oriented concepts such as classes and namespaces, while methods can (optionally) be written in a functional style.
