how to check upload finish ( IE.au3 ) ?

[kwixro 0]

#include <IE.au3>
.....
$oIE = _IECreate("abc.com/upload.php")
...
$input = _IEFormElementGetObjByName($oform,"file")
_IEAction($input, "focus")
...
Send("C:\test.png")
Send("{Enter}")
...

After Enter, abc.com/upload.php start upload file 'test.png'. How can autoit check upload file completed?

Thanks!

Try to wait for a text in web page who said Upload is finished...
