Exists Method (Windows Script Host)

 

Indicates whether a specific key value exists in the WshNamed object.

object.Exists(key)

object

WshNamed object.

Key

String value indicating an argument of the WshNamed object.

The Exists method returns a Boolean value. It returns true if the requested argument was specified on the command line (otherwise, it returns false).

Legacy Code Example

Consider the following information typed at the command line.

cscript myScript.vbs /c:"WSH is a wonderful thing"

You could use these two lines of Visual Basic Scripting Edition (VBScript) code to determine whether the following command line switches were used to start the script.

WScript.Echo WScript.Arguments.Named.Exists("C")
WScript.Echo WScript.Arguments.Named.Exists("D")
