loading an HTML page on winEmbed browser window

[CORONA,FATIMA (HP-Boise,ex1)]

Hi,

I am trying to open winEmbed with an HTML page as a default page when it
first starts up, instead of tyring to open a URL site. I don't know what
these functions do in the file winEmbed.cpp  though... which I believe are
the ones that start searching the URL and load it in to the browser window
as a start up page.

nsresult OpenWebPage(const char *url)
{
        :
        :
        :
            // Start loading a page
        nsCOMPtr<nsIWebBrowser> newBrowser;
        chrome->GetWebBrowser(getter_AddRefs(newBrowser));
        nsCOMPtr<nsIWebNavigation> webNav(do_QueryInterface(newBrowser));
        return webNav->LoadURI(NS_ConvertASCIItoUCS2(url).GetUnicode(),
            nsIWebNavigation::LOAD_FLAGS_NONE);
    }

    return rv;
}   

Does anybody know what each of these lines do? 

Thanks,

Fatima
