Script-it.exe (NT 4 Server)

Control GUI applications - feed values into dialogue boxes, press OK etc

Syntax
      SCRIPTIT script_file

Script-It.exe is no longer available for download at Microsoft.com

An alternative is the freeware tool AutoIt

Originally for NT4 Server, although it does run (rather crankily) on more recent OS's. Script-it works by recognising the Window Title of each open Application / Document / Dialogue box.

The script_file is a .ini text file prepared in advance with all the keystrokes you want to send to the appropriate Window.

Example Script file:
runwait=notepad.exe
Untitled - Notepad=Hello World
run=calc.exe

This will launch an instance of Notepad and then send the string "Hello World", when notepad.exe is closed the script will run CALC.exe
