how fast we can grab newly opened window object property

Hi TestCompleters,

i am working on java applet based desktop application. i want to get clarification on how fast the testcomplete take the object property. 

Consider, I open a new window in the application. Window is designed by java applet. it have some loading contents(consider a web page having unloaded images). I use 'FindChild().Visible' . It returns the value only the window loaded fully with the loading contents. Untill i wont return anything(I recoginze this using break point. I put a breakpoint on previous line. After 'FindChild().Visible' i put another break point. I hope you can find the logic). 

But i want to know like, if a new window appers(max 100 ms),But the object gets loaded only after the entire window is ready to use(ready to use means - get object only after the loading contents are fully loaded).
