如何从SYSTEM帐户向登录的用户显示MessageBox？

Question

I want to create an application, which will query the free space from C:\\ and if it is lower then a limit, it should show a messagebox to the user, that he/she should free up some space on C:. This application would run under the SYSTEM account. My problem is that this messagebox is not visible to the logged on user. So my question is how can i show a messagebox to the logged on user from SYSTEM account? If someone could provide some example code, i would be very thankfull.

Thanks!

You have to write a seperated user interface, try to search for interprocess communication, like Yahia mentioned, thats not the safe way to go. However there is TerminalServices API doing the session switch for you, right now the user would get some notification in taskbar but no user interface at all, thats right.
