3.4.2 Advanced Visual Basic
The following Visual Basic code sample is broken down into four sections, the first of which
deals with configuring document preferences.
Document Preferences
In this code segment, variables are declared and a Photoshop Application object is created.
Default configuration settings for the application are saved into variables so that they can be
restored later when the script completes. These are the default configurations you most
probably set up using the File/Edit/Preferences dialog when you initially installed and
configured Photoshop.
The script goes on to define new preferences for rulers and units and sets these to inches and
pixels, respectively. The psDisplayNoDialogs enumeration is specified so that the script runs
without user intervention. Users will not, in other words, be required to press "OK" each time
the script generates a new dialog for display.
Next, variables are declared that store document dimensions in inches and document
resolution in pixels. A display resolution is declared and the text "Hello, World!" is assigned to
a string variable.
Finally, a document object is created, if one does not already exist.
