Visual Basic Question - About loading up websites (easy)?

[Will]

Hi everyone, this should be easy however I don't know the answer since I am only a beginner in programming.
I have a webbrowser object on my vb form and a button with the coding to load up a certain website which is:

webbrowser1.Navigate("[website]")

It works perfectly fine, the problem I am having is, I want the website fully loaded before the next line of coding runs.
So if I had a code like:

webbrowser1.Navigate("[website]")
msgbox("Finished loading")

I don't want the message box to popup until the website is actually loaded. Does anyone know a way of doing this??

Thanks =]
5 stars for the best answer.
Help please
