yes, i have to use MFC because there are some classes in my app which need it.
creating the tray icon and the popup is no problem. i only have to bother with getting rid of unnecessary dialogs and/or windows. the result should be a MFC based application with only a tray icon and a popup menu as its GUI - neither a dialog nor a window can be visible.
aren't there any sample codes out there? i can't believe that i'm the first one who's trying this.
