"var f = new ActiveXObject('Scripting.FileSystemObject');" not working with IE8

I am very new in using ActiveX controll through java script,

I write var f = new ActiveXObject('Scripting.FileSystemObject'); in my code and Its was working fine on IE6, but recently I upgraded my I开发者_JS百科E6 to IE8 and what I found now its not working on IE8, returning the error given below:

I googled this and found there is something missing in the IE ActiveX setting and got resolved this problem, But now I have a requirement that it should be solved without playing with IE8 setting.

Can anyone have any idea about this, any suggestion would be really appreciable...
