VBScript
Scripts written in VBScript are plain text files that can be viewed
with any text editor. They can be executed on any Windows system
that has the Windows Scripting Host (WSH) installed. The WSH is
installed by default on Windows 98/NT 4 and later versions.
VBScript files have the extension .vbs.
Executing a VBScript
To execute a VBScript script, you have three options:
1
Double-click on the VBScript file.
2
On the command line, type the full file path followed by the
scripts command line parameters.
3
In the Windows Run dialog, type cscript with a space behind
it followed by the full file path of the script and its command line
parameters. CScript is a program that executes scripting files.
VBScript scripts can only have very simple dialogs as the user inter-
face. Since our example script needs the source and destination fold-
ers as input from the user, you have to supply them as command line
arguments. The first argument specifies the source folder and the sec-
ond argument specifies the destination folder for the downsampled
images. Since double-clicking on a scripting file does not support
arguments, we have to use either option 2 or option 3 to execute the
script.
To view the VBScript version of the Downsample script, open the
file ExampleScripts\Downsample\VBScript\dwnsm-
ple.vbs. with any text editor. Lets assume that you copied this
script to the following location:
C:\VBScripts\dwnsmpl.vbs
Lets further assume that you have some JPEG files at: C:\JPEGs\
Lets also assume that the following destination folder exists:
C:\ds_JPEGs\
You can execute the script now in two ways:
Open a Command Prompt window and type the line :
C:> C:\VBScripts\dwnsmpl.vbs C:\JPEGs
C:\ds_JPEGs
