Open winrunner first & then open the web based AUT. If Winrunner is opened after the IE is opened, then Winrunner fails 2 recognize the GUI Objects.
If u browse through this forum, u will find lot many threads 4 the same query.Pls go through it.U will get a good idea about this behavior.
what is your 'text box'? a 'static text object'? you can use 'static_get_info' or 'obj_get_info; to check the property first (but sometimes if WR con not recognize the object, it has 'no property' to check). Good luck to you.
