Visual Basic Question - Loading websites in a web browser object?

[Will]

Hello everyone I am having problems.
What I want is the web browser object to show a website fully before executing the next piece of code after it.

For example
I have:

webbrowserobject.Navigate("http://www.yahoo.com")
msgbox("Finished loading")

In a button. When you click the button it displays the message box before the webpage is loaded. Can anyone help me please?
Hmmm it doesn't seem to work?
Anybody with other suggestions?
Please we are so close =]
