I just want to modify some of the contents on all the SharePoint pages be it adminstration page or some site page or any other page using my script (Javascript) and AJAX code.
My ultimate aim is to show presence (in the same way as sharepoint show lync presence) and some widget (UI) on right click(or mouseover) on my presence pawn. My javascript will connect to my server for getting presence information.
I know if add a webpart I can execute my Javascript on my webpart page but I want to do it on the page.
What do you think if I can do something like above. Any ideas or suggestion please.
PS. I checked the WSS3.0 installation on ISS, to my surprise there is no static page, I suppose all the pages are created dynamically (may be rendered by some dll to IE on runtime). So I just can't embed my JavaScript so easily on pageload.
