Answer 1

I don't know if possible, but if it is, the parent needs to be SHELLDLL_DefView and not the underlying ListView.  In other words, the system ListView and the form have to be siblings.

On top of that you must set the Z-order of the siblings so the the ListView is kept on top of the newly added form.

will anyone here know how to deal with it ?

Answer 3

The best you're going to get is writing a COM object, embedding it in a webpage and using the Display Settings -> Desktop -> Customise -> Web.

I'm not sure if you can enable/disable these programatically (I would assume so), so that might help

Answer 4

may be you just use a maximized transparent form and redirect mouse messages to desktop and taskbar. I realy dont know how to do this, but maybe WMI or com programming helps you.
