How can i open windows calculator from website? with javascript or actionscript? Ive tried avtiveX but its only in explorer, I want to open calculator from google chrome
See Mohammad Albay's answer. Windows installs a URI handler so you can use the calculator:
scheme. This answer is (no longer?) correct specifically for Calculator (what the OP asked about) but I can't remove it because of the accepted mark.
If Windows didn't support that scheme, the answer would be: You can't*. Consider the implications if you could open an arbitrary program on someone's computer from a web page...
(* Without writing and installing a plug-in, and plug-ins are increasingly being phased out by browser vendors in favor of sandboxed extensions.)
