Description
Occurs when the Web browser starts downloading a document.
Write an OnDownloadBegin event handler to take specific action after the Web browser has located a document and immediately before it starts downloading the document. For example, use the OnDownloadBegin event to launch an animation control the represents downloading or a progress bar that is updated by an OnProgressChange event handler. The control can then be stopped in an OnDownloadComplete event handler.
Note: To take specific action when the Web browser looks up the resource, rather than when it begins downloading, use the OnBeforeNavigate2 event. OnDownloadBegin occurs shortly after OnBeforeNavigate2.
