PDF plugin in webbrowser control

When I clicked PDF link (url), the PDF (once downloaded) would be opened in Internet Explorer (IE). I noted the status bar (shown in attached figure) showed 'Done' once the PDF loaded completely.

However, when I monitored for webbrowser1_documentcomplete event, it did not work, ie. when webbrowser1_documentcomplete event was triggered, the PDF WAS NOT loaded completely.

One of the users in this forum mentioned that it's because the PDF plugin. I wonder whether we can monitor the status of the work/process done by PDF plugin. like how IE shows the Status (done). Could someone pls advise?

If we can not implement in VB, any other languages (C++, Delphi, etc) can do it? Pls advise.

Thanks
