External Programs

Overview

You can run External Programs (External Programs) and pass variable values to the program ( examples: .bat batch Scripts, .exe executable files, etc.). In general, any script or executable that you can start from the Windows Start -- Run dialog). External Programs can be started by a Start External Program Step from a Script in the Automator . The External Program could also be a Macro Recorder program that starts a desired program and simulates manual menu selections or button presses. AutoHotkey is a free, open-source utility that will perform Macro Recorder operations. It can also be document file if the document type is associated with an executable program. For example, if "txt" files are associated to Notepad, you could specify a text document in the Run field (ie Mydoc.txt). When invoked, Notepad would open Mydoc.txt.

There is a two Step setup process.

How to Run an External Program

  1. In the Automator , open any Script with the Script Editor.
  2. Pick Start External Program in the Step type list, then click the Add a Step button.
  3. You'll be prompted to pick the target External Program.
  4. Then you are prompted to enter any Variables you want to pass to the program.

When you run the Script and this Step is executed, the External Program will be started and the Variables passed as start-up variables (parameters).

You can change the Variables later, by editing the Step with the Step Editor (see Figure 2).

External Programs and Active Window Focus

When you run an external program, it typically open up its own program window and that window becomes the active (focused) window. In Windows, keyboard keystrokes and mouse clicks are directed to the active window. Video Mill provides a way to automatically return focus to itself after invoking an external program. And allows for a preset amount of time to expire before returning focus so that the external program can complete some work if necessary. This is especially important to Sound Mill Easy Player users who are operating the player with a remote control since the Easy Player window must be the active window to receive button push signals from the remote. See the the External Programs Editor above for details on these settings.
