Event-Driven Program An event-driven program is one that largely responds to user events or other similar input. The concept of event-driven programming is an important one in application development and other kinds of programming, and has spawned the emergence of event handlers and other resources...
In a computing context, an Event is any identifiable occurrence that has significance for system hardware or software. Events can be user-generated, such as a mouse click or keystroke, or system-generated, such as a program loading. Event-driven programming separates event-processing logic from t...
An event mesh is a dynamic infrastructure for sending notifications to applications across a distributed environment. In the context of event-driven architecture (EDA), an event is a change, action, or observation in a system that produces a notification, which is then sent to other systems that...
An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the necessary actions, an...
In some cases, an EXE file can be triggered passively. For example, Windows AutoPlay and AutoRun execute files automatically when a particular event happens. For example, when aUSBdevice is connected, it automatically runs the USB'sfirmware. Any executables in the Windows startup file will also...
First, you have to declare an event in Solidity. Then, you emit the event with the keywordemit. The following is an example of how to declare an event: Copied eventmoneySent(address_from, address_to, unit_amount); The event, when triggered, will inform the external application that someth...
What Is an Exception?The term exception is shorthand for the phrase "exceptional event." Definition: An exception is an event, which occurs during the execution of a program, that disrupts the normal flow of the program's instructions. When an error occurs within a method, the method ...
actions. what is a user interface (ui) framework? a ui framework is a software framework that provides developers with a set of tools, libraries, and components to build user interfaces more efficiently. it offers pre-built ui elements, layout management, event handling, and other ...
An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the necessary actions, an...
when you attach an event listener to an element or object, it waits for a particular event to occur. when the event is triggered, the listener executes a specified function or block of code. this function can perform various actions, such as updating the user interface, processing data, or...
