Closing an application opened with ActiveXObject

Hi,

I am using the LaunchinIE.dll to make a MS Word file automatically open then a URL link to the word file is clicked.

However, i would like to know if there is a Close method that I could to close the application for a web page once the application is open. in JavaScript, I tried using
objse.Close();
unsuccessfully.

I am pasting the JavaScript code used to open the file.
THanks in advance

var obj = new ActiveXObject("LaunchinIE.Launch");
var objse = obj.ShellExecute( "open", "myWordFile.doc");
