How to know whether a page has loaded completely

Hi 



I would want to know using VB script how can i actually know whether my page is loaded completely before i perform any actions 

similar to selenium.waitForPageToLoad(time in milliseconds)



I have tried waitForWindow but the documentation tells me that it waits until the object appears in object browser but in my situation iexplore process appears but the page is still not loaded fully 



I would want to wait until the page is loaded 



Thank you in advance 



regards
