The traditional first project in any programming language is to display the message “Hello
World!”In this section, we’ll create a new Photoshop document, then add a text item
containing this message with examples in AppleScript, Visual Basic, VBScript and JavaScript.
IMPORTANT:
Before attempting to run these sample scripts make sure you have properly
installed the Scripting Support module for Photoshop.

As you look through the script, you’ll see how to create, then address, each object. The
AppleScript commandtell indicates the object that will receive the next message we
send.

3.3.3 VBScript
You don't need to use Visual Basic to run scripts on Windows. Another way to script
Photoshop is to use a VBA editor (such as the one that is included in Microsoft Word) or to use
Windows Scripting Host.
Most Windows systems include Windows Scripting Host. If you do not have Windows
Scripting Host or would like more information about Windows Scripting Host visit the
Microsoft Windows Script Technologies Web site at http://msdn.microsoft.com/scripting/.
VBScript considerations
Both VBA and Windows Scripting Host use VBScript as their scripting language. The syntax
for VBScript is very similar to the Visual Basic syntax. The three main differences relating to
the scripts shown in this guide are:
– VBScript is not as strongly typed as Visual basic. In Visual Basic you say:
Dim aRef as Photoshop.ArtLayer
in VBScript you say:
Dim aRef
For VBScript simply omit the “as X”part
– VBScript does not support the “as New Photoshop.Application”form.
In Visual Basic you can retrieve the Application object as:
Dim appRef as New Photoshop.Application
In VBScript you write the following to retrieve the Application object:
Dim appRef
Set appRef = CreateObject("Photoshop.Application")
– VBScript does not support enumerations. Here's an example of how to set the extension
type that can later be used save a document.
Dim extType As Photoshop.PsExtensionType
extType = psUppercase
In the Visual Basic reference the value of the various enumerated values are specified in a
parenthesis after the enumeration name. For example “psConvertToCMYK (3)”means that
from Visual Basic you can use the term “psConvertToCMYK”to refer to the CMYK
document mode, scripting languages that do not use a typelibrary can use the value 3.

Here’s an example VBScript:
' Hello World Script
Dim appRef
Set appRef = CreateObject( "Photoshop.Application" )
' Remember current unit settings and then set units to
' the value expected by this script
Dim originalRulerUnits
originalRulerUnits = appRef.Preferences.RulerUnits
appRef.Preferences.RulerUnits = 2
' Create a new 4x4 inch document and assign it to a variable.
Dim docRef
Dim artLayerRef
Dim textItemRef
Set docRef = appRef.Documents.Add(4, 4)
' Create a new art layer containing text
Set artLayerRef = docRef.ArtLayers.Add
artLayerRef.Kind = 2
' Set the contents of the text layer.
Set textItemRef = artLayerRef.TextItem
textItemRef.Contents = "Hello, World!"
' Restore unit setting
appRef.Preferences.RulerUnits = originalRulerUnits
To run this script create a text file and copy the script into it. Save the file with a “vbs”
extension. Double-click the file to execute.
