i never used them (because i hate win32 coding) but you should have a look at the Win32:: modules on cpan. maybe some of them can do what you want. at least the Win32 API has to support actions like that, because i already saw (native) programs doing it.

besides that, please note that we are a german perl forum. if you prefer to speek/type english, there is a very large perl community at http://www.perlmonks.org.
