HTML - How do I know when all frames are loaded?

Question

I'm using .NET WebBrowser control. How do I know when a web page is fully loaded?

I want to know when the browser is not fetching any more data. (The moment when IE writes 'Done' in its status bar...).

Notes:

• The DocumentComplete/NavigateComplete events might occur multiple times for a web site containing multiple frames.
• The browser ready state doesn't solve the problem either.
• I have tried checking the number of frames in the frame collection and then count the number of times I get DocumentComplete event but this doesn't work either.
• this.WebBrowser.IsBusy doesn't work either. It is always 'false' when checking it in the Document Complete handler.

Here's how I solved the problem in my application:

private void wbPost_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (e.Url != wbPost.Url)
        return;
    /* Document now loaded */
}
