First I want to thank you on your effort.

My application has three radiobuttons (Stand By, Shutdown and Restart) I 
also have a TEdit control in which user enters desired time to execute 
selected option (format is HH:MM:SS -> for example shutdown my computer 
at 19:15:00)
If I use timeout does it mean that I don't have to use TTimer control?

What I'm trying to do is not to have a shortcut on my desktop and not to 
call my application by double click on the icon on the desktop or 
anywhere else, but to call it by clicking on the Start->Turn Off Computer.

Altering the dialog seems to be the right way. I have to add TEdit 
control which will be used for entering time (if it's left empty, action 
should occur immediately and if not timer should be started). But as you 
probably guessed I don't have much experience with API functions and 
installing a hook, the only example I saw is installing a mouse hook 
(http://www.leunen.com/cbuilder/hook.html), so I'll try to find some 
tutorials and search on 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/WindowsUserInterface/Windowing/Hooks.asp 
, to expand my knowledge. If you have any suggestions or links to 
examples please tell me.

Thank you very much.
