Windows Forms
Windows Forms, also known as WinForms, is a free, open-source graphical user interface (GUI) class library for building Windows desktop applications, included as a part of Microsoft .NET, .NET Framework or Mono, providing a platform to write client applications for desktop, laptop, and tablet PCs. While it is seen as a replacement for the earlier and more complex C++ based Microsoft Foundation Class Library, it does not offer a comparable paradigm and only acts as a platform for the user interface tier in a multi-tier solution. At the Microsoft Connect event on December 4, 2018, Microsoft announced releasing Windows Forms as an open source project on GitHub. It is released under the MIT License. With this release, Windows Forms has become available for projects targeting the .NET Core framework. However, the framework is still available only on the Windows platform, and Mono's incomplete implementation of Windows Forms remains the only cross-platform implementation. Arch ...

Event Handler
In computing, an event is a detectable occurrence or change in the system's state, such as user input, hardware interrupts, system notifications, or changes in data or conditions, that the system is designed to monitor. Events trigger responses or actions and are fundamental to event-driven systems. These events can be handled synchronously, where the execution thread is blocked until the event handler completes its processing, or asynchronously, where the event is processed independently, often through an event loop. Even when synchronous handling appears to block execution, the underlying mechanism in many systems is still asynchronous, managed by the event loop. Events can be implemented through various mechanisms such as callbacks, message objects, signals, or interrupts, and events themselves are distinct from the implementation mechanisms used. Event propagation models, such as bubbling, capturing, and pub/sub, define how events are distributed and handled within a system ...

Attribute (computing)
In computing, an attribute is a specification that defines a property of an object, element, or file. It may also refer to or set the specific value for a given instance of such. For clarity, attributes should more correctly be considered metadata. An attribute is frequently and generally a property of a property. However, in actual usage, the term attribute can and is often treated as equivalent to a property depending on the technology being discussed. An attribute of an object usually consists of a name and a value. For an element these can be a type and class name, while for a file these can be a name and an extension, respectively. Rules and typing * Rules: Each named attribute has an associated set of rules called operations: For example, one doesn't sum characters or manipulate and process an integer array the same way as an image object. Neither does one process text as if it was type of floating point ( decimal numbers). * Data types: It follows that an object d ...

Drag-and-drop
In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects. As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, or what command is performed by the drag and drop, which can decrease usability. Actions The basic sequence involved in drag and drop is: * Move the pointer (computing WIMP), pointer to the object * Press, and hold down, the button on the computer mouse, mouse or other pointing device, to "grab" the object * "Drag" the object to the desired location by moving the pointer to this one * "Drop" the object by releasing the button Draggi ...

Microsoft Active Accessibility
Microsoft Active Accessibility (MSAA) is an application programming interface (API) for user interface accessibility. MSAA was introduced as a platform add-on to Microsoft Windows 95 in 1997. MSAA is designed to help assistive technology (AT) products interact with standard and custom user interface (UI) elements of an application (or the operating system), as well as to access, identify, and manipulate an application's UI elements. AT products work with MSAA enabled applications in order to provide better access for individuals who have physical or cognitive difficulties, impairments, or disabilities. Some examples of AT products are screen readers for users with limited sight, on screen keyboards for users with limited physical access, or narrators for users with limited hearing. MSAA can also be used for automated testing tools, and computer-based training applications. The current and latest specification of MSAA is found in part of Microsoft UI Automation Community Promise Spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Managed Code
Managed code is computer program code that requires and will execute only under the management of a Common Language Infrastructure (CLI); Virtual Execution System (VES); virtual machine, e.g. .NET, CoreFX, or .NET Framework; Common Language Runtime (CLR); or Mono. The term was coined by Microsoft. Managed code is the compiler output of source code written in one of over twenty high-level programming languages, including C#, J# and Visual Basic .NET. Terminology The true and fine distinction between managed and unmanaged code is prevalent and only relevant when developing applications that interact with CLR implementations. Since many older programming languages (list) have been ported to the CLR, the differentiation is needed to identify managed code, especially in a mixed setup. In this context, code that does not rely on the CLR is termed "unmanaged". A source of confusion was created when Microsoft started connecting the .NET Framework with C++, and the choice of h ...

Windows API
The Windows API, informally WinAPI, is the foundational application programming interface (API) that allows a computer program to access the features of the Microsoft Windows operating system in which the program is running. Programs can access API functionality via shared-library technologies or via system-file access. Each major version of the Windows API has a distinct name that identifies a compatibility aspect of that version. For example, Win32 is the major version of Windows API that runs on 32-bit systems. The name, Windows API, collectively refers to all versions of this capability of Windows. Microsoft provides developer support via a software development kit, Microsoft Windows SDK, which includes documentation and tools for building software based on the Windows API. Services This section lists notable services provided by the Windows API. Base Services Base services include features such as the file system, devices, processes, threads, and error handl ...

Button (computing)
In computing, a button (sometimes known as a command button or push button) is a Graphical control element (software), graphical control element that provides the user a simple way to trigger an event (computing), event, like searching for a query at a search engine, or to interact with dialog boxes, like confirming an action. Overview A typical button is a rectangle or rounded rectangle, wider than it is tall, with a descriptive caption in its center. Other buttons may be square or round, with simple Icon (computing), icons. The most common method of pressing a button is clicking it with a pointer (user interface), pointer controlled by a mouse (computing), mouse, or a touchpad, but other input such as keystroke can be used to execute the command of a button. However, a button is not always restricted to a rectangular shape. The sole requirement of button interaction is that the user can execute a command by a point-and-click, click action. Thus, pictures and background areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text Box
A text box also called an input box, text field or text entry box, is a control element of a graphical user interface, that should enable the user to input text information to be used by a program. Human Interface Guidelines recommend a single-line text box when only one line of input is required, and a multi-line text box only if more than one line of input may be required. Non-editable text boxes can serve the purpose of simply displaying text. A typical text box is a rectangle of any size, possibly with a border that separates the text box from the rest of the interface. Text boxes may contain zero, one, or two scrollbars. Text boxes usually display a text cursor (commonly a blinking vertical line), indicating the current region of text being edited. It is common for the mouse cursor to change its shape when it hovers over a text box. Standard functionality Typical implementations allow a user to do the following. (The keys indicated relate to the text box widgets in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
