If there is iframe in the page, then each iframe will trigger a DocumentComplete event. So how do we judge whether it is complete? ? Hey, TWebBrowser control is not a Busy property right procedure TfrmIE2.WebDocumentComplete? (Sender: TObject; pDisp: IDispatch; var URL: OleVariant); begin if not (Web.Busy) then begin ShowMessage ( 'downloaded'); End; end; For each connection (whether the mouse click or with a NaviGate2 method connection), TWEBBRowser process is like this: OnBeforenaviGate2 <- This event is triggered when the link will be triggered onnavigateComplete2 <- successful link to this page (later There will be the following events) OnDownloadbegin <- Start downloading the OndownloadComplete <- Download End OndocumentComplete <- The page is downloaded for each HTML page. If it is FRAME or IFRAME, the file is treated as an HTML page. That is to say, if there is 3 iframes in a page, then a total of 4 BeforenaviGate2 events. For each connection and the binaries you need to display (such as * .gif, *. Bmp, *. Jpg ...) will Trigger a DownloadBegin and DownloadComplete events.
