    The BackgroundWorker component allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the TBackgroundWorker component provides a convenient solution.

    To execute a time-consuming operation in the background, create a TBackgroundWorker component and listen for events that report the progress of your operation and signal when your operation is finished. You can create the TBackgroundWorker component programmatically or you can drag it onto your form from the Components palette.

    To set up for a background operation, add an event handler for the OnWork event. Call your time-consuming operation in this event handler. To start the operation, call Execute method. To receive notifications of progress updates, handle the OnWorkProgress event. To receive feedbacks from the operation in background, handle OnWorkFeedback event. To receive a notification when the operation is completed, handle the OnWorkComplete event.
