No!!

You better open a new thread and instruct the WebBrowser from there

Application.DoEvents() is kinda evil.

Here is how you can start

System.Threading.Thread t = new System.Threading.Thread(() =>
{
    yourWebBrowser.Navigate("http://Google.com");
});

t.ApartmentState = System.Threading.ApartmentState.STA;
t.Start();

To get notified that the page has been loaded you can subscribe to the DocumentCompleted event as so:

yourWebBrowser.DocumentCompleted += WebBrowserDocumentCompleted;

void WebBrowserDocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
{
    throw new NotImplementedException();
}
