Wait Internet Explorer to load page

Hi, im testing the performance of my portal IE9 with the installed IE9...

The test is this:
1) Open browser
2) Navigate to a webpage
3) Wait until its full loaded
4) Close browser

My problem is step 3... I cannot use _IECreate function because i cannot select portal IE9... How can i wait (without using winwait, sleeps, or something like that) until is full loaded?

Thanks
