preferences.typeUnits = TypeUnits.PIXELS

In the Adobe Photoshop CS3 JavaScript Scripting Reference, or in the ExtendScript Object Model Viewer, look 
up the 

Preferences

 object to view all of the settings properties you can use. Additionally, look up the 

preferences

 property on the 

Application

 object.

It is important to be able to control dialogs properly from a script. If a dialog appears, your script stops 
until a user dismisses the dialog. This is normally fine in an interactive script that expects a user to be 
sitting at the machine. But if you have a script that runs in an unsupervised (batch) mode, you do not want 
dialogs to be displayed and stop your script.

You use the 

display dialogs

 (

DisplayDialogs/displayDialogs

) property of the 

Application

 object 

to control whether or not dialogs are displayed.

Using dialogs in your script is roughly equivalent to using stops in a Photoshop CS3 action. 

The following script prevents dialogs from being displayed:

set display dialogs to never

In the Adobe Photoshop CS3 AppleScript Scripting Reference or in the Photoshop CS3 AppleScript Dictionary, 
look up the 

Class application

 to find the values you can use for the 

display dialogs

 property. 

To set dialog preferences, you use the 

DisplayDialogs

 property of the 

Application

 object. 

appRef.DisplayDialogs = 3 
'for PsDialogModes --> 3 (psDisplayNoDialogs)

Note that, because 

DisplayDialogs

 is a property of the 

Application

 object, you must reference the 

Application

 object in the script to get to the property. 

In the Adobe Photoshop CS3 Visual Basic Scripting Reference, or in the Visual Basic Object Browser, look up 
the 

Application

 object property 

DisplayDialogs

. You’ll see the value type for this property is the 

constant 

PsDialogModes

. You can also look up the options for 

PsDialogModes

.

To set dialog preferences, you use the 

displayDialogs

 property of the 

Application

 object. 

displayDialogs = DialogModes.NO

In the Adobe Photoshop CS3 JavaScript Scripting Reference, or in the ExtendScript Object Model Viewer, look 
up the 

Application

 object property 

displayDialogs

, and then look up the constant 

DialogModes

.
