Use WebBrowser control in VB6 to open an Office document on Win7

I want to know : How to use WebBrowser control in VB6 to open,edit,close,save & print an Office document on Win7 machine ?
I read that we needs to update BrowserFlags and EditFlags value of window registry via VB6 code to open word doc inside the webBrowser control but we do not have rights to edit window registry on win7 machine .
