‘ This example assumes docRef is already the ActiveDocument
Dim theChannels 
theChannels = Array(docRef.Channels(0), docRef.Channels(2))
docRef.ActiveChannels = theChannels

Alternatively, select all component channels using the 

ComponentChannels

 property of the 

Document

 

object:

appRef.ActiveDocument.ActiveChannels= _

appRef.ActiveDocument.ComponentChannels

Set the active channels to the first and third channel using a channel array:

theChannels = new Array(docRef.channels[0], docRef.channels[2])
docRef.activeChannels = theChannels

Alternatively, select all component channels by using the 

componentChannels

 property of the 

Document

 

object:

app.activeDocument.activeChannels =

activeDocument.componentChannels

You use the 

open

/

Open

/

open()

 command of the 

Application

 object to open an existing document. You 

must specify the document name (that is, the path to the file that contains the document) with the 
command. 

Because Photoshop CS3 supports many different file formats, the 

open/Open/open()

 command lets you 

specify the format of the document you are opening. If you do not specify the format, Photoshop CS3 
infers the type of file for you, which is called the file’s default format. The following examples open a 
document by inferring the most appropriate format to use:

set theFile to alias "Applications:Documents:MyFile"
open theFile

fileName = "C:\MyFile"
Set docRef = appRef.Open(fileName)

var fileRef = File(app.path + "/Samples/Fish.psd")
var docRef = app.open(fileRef)

Notice that in JavaScript, you must create a 

File

 object and then pass a reference to the object to the 

open()

 command.
