    Wait for complete sit load in IE WebBrowser control

    Hello.
    I'm trying to tell my program to wait until website isn't fully loaded before continuing.
    I tried already:
    WebBrowser.IsBusy, but it doesn't work. It freezes my program very often, and didn't work properly even one time.
    while (WebBrowser.DocumentCompleted != (WebBrowserDocumentCompleted) 1) freezes my program too.
    Only WebBrowserDocumentCompletedEvent works fine, but it's called even 7 times when website is loading, otherwise i don't know how to tell my function to wait on response from this event.

    Is there any other solution?
    Thank you a lot for your advices!
    Greetings, genotypek.

    Looks like the event gets fired once for each of seven frames making up your complete page. In this case, I think, you should be able to identify the frame you're actually interested in by the Url property of the event args parameter passed to your handler.

    Okay, but what to do, if I'm not completely sure what is this properly url of this site which my IE is loading?
    And in this case, how to make communication between my event and my part of code?

    There's a good chance that the URL of interest is the one you navigated to. Content hosted in frames typically is something like navigation sidebars or ads, for example.

    As far as I recall, the document completed event handler is invoked on the GUI thread, so you can do practically anything you want in your event handler, including GUI updates, or call methods of your own that do. To make really sure that you're running on the GUI thread, you can put this line at the beginning of your event handler (assuming you have a using namespace System::Diagnostics; in the respective source file):

    Code:
    Debug::Assert(!InvokeRequired);
    Try to avoid long-running processes (like polling loops), though, because that blocks the GUI thread and freezes your application, as you have seen.
