hello (:
I have long searched for it and finally decided to make himself, an analogue tail for windows.
The utility of *nix (works for xorg) is used to display any information to the desktop, but the main idea:
text only, no backgroundI apologize in advance, I wrote their own language (Russian) description of the parameters, but I hope to source code, you will understand everything
ScreenshotsRun without parametres

Any string

Read log files

Result from any command

Attched files:
bbtail.exe - it for bb4win shell (xoblite, bbclean, bblean etc...)
tail.exe - for explorer.exe shell
becouse text printing on desktop and need to get handle control object of desktop...
Code:
; explorer.exe
ControlGetHandle("Program Manager","","SysListView321")
; blackbox.exe
ControlGetHandle("","","DesktopBackgroundClass1")
tail.au3 - source, AutoIt3

(I use 3.3.0.0 version)
Enjoy! and sorry about my english)..
