Controls and startup problems

I have an application that I would like to be run on startup. I would also like to have an icon on the system tray (next to the clock) to show that user that the application is still running. Can someone please tell me how to do this? Is it easy to implement a menu that appears when the user right clicks on the tray icon?

Also I have an activeX control in an SDI program of mine. I wish to catch when the user clicks on it. I can catch a user click if I have the control in a dialog box but I don't know how to do this in a document of an SDI program. I know the click is a stock event and I am sure it is already built into the control (as I can use it when in a dialog box) but its just a case of using it in the document.


Thanks

Mark
