Pretty good so far!
What exactly is not working?
I am developing AIr application using dreamwaever. we have crated
native window .
For the home page their are different links which will open the
different html files in same window hiding the home page. how should i
hide and show different html files in main native window.
If you want to open HTML links in a new native window which you fully control, you need to put some JS on those links and open the windows programatically.
See the second example in the "Creating an HTML window" on this page: http://help.adobe.com/en_US/air/html/dev/WS5b3ccc516d4fbf351e63e3d118666ade46-7e0a.html#WS 5b3ccc516d4fbf351e63e3d118666ade46-7df4
