DoWorkEventHandler Delegate

Represents the method that will handle the DoWork event that is raised when the RunWorkerAsync method is called.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)


Public Delegate Sub DoWorkEventHandler ( _
    sender As Object, _
    e As DoWorkEventArgs _
public delegate void DoWorkEventHandler(
    Object sender,
    DoWorkEventArgs e



When you create a DoWorkEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event-handler method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events, Delegates, and CLR Event System Conventions.
