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

object.Exists(key)

Parameters

object

WshNamed object.

Key

String value indicating an argument of the WshNamed object.

Remarks

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

Example

Consider the following information typed at the command line.

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

You could use these two lines of JScript code to find out 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"));
