Ich habe Dir mit AutoHotkey etwas namens "GoDown" geschrieben und kompiliert:
#SingleInstance Ignore
Secs = %1%
If (StrLen(Secs)=0)
Secs := 10
Gui +LastFound +AlwaysOnTop -Caption +ToolWindow
Gui Color, EEAA99
Gui Font, s228
Gui Add, Text, Xp+20 Yp+2 W200 Vdisp Cred
WinSet TransColor, EEAA99
Gui Show, NoActivate, Display
secsLeft := Secs
SetTimer, ShowTimer, 1000
Gosub ShowTimer
Return
ShowTimer:
secsLeft--
IfEqual, secsLeft, 0
{
SetTimer ShowTimer, Off
Gui, Destroy
Shutdown, 1
ExitAPP
}
Else
GuiControl, Text, disp, %secsLeft%
Return
Syntax:
GoDown.exe [Zeitspanne in Sekunden (Standard: 10 Sekunden)]
