VBScript - Passing CmdLine Arguments

I was searching on net, how to pass the command line arguments. It is possible. We can pass the command line arguments in VBScript. If you have worked with command-line tools, you are already familiar with the concept of arguments. Arguments can be divided as Named Arguments and UnNamed Arguments.

Named arguments
Named arguments are arguments that consist of two parts: a name and a value. The name must be prefaced with a forward slash, and a colon must separate the name from the value. The slash prefix and the colon separator are fixed and cannot be changed. See below Example.

RemoteServer.vbs /Host:AppSrv1 /App:Symantec /TimeLimit:2000
Item : Value

UnNamed arguments
The WshUnnamed filtered collection contains the one unnamed argument. The WshUnnamed Count method and Length property return the number of filtered arguments in the WshUnnamed collection. Example is given below.

FormatMask.vbs "D:\VB\FormatMask\Complex.xls" 30 12
Item : Value
0 : D:\VB\FormatMask\Complex.xls
1 : 30
2 : 12

Source: Working with Command-Line Arguments

Code: Example of UnNamed arguments

If WScript.Arguments.Count = 3 Then
ServerName = WScript.Arguments.Item(0)
EventLog = WScript.Arguments.Item(1)
EventID = WScript.Arguments.Item(2)
Wscript.Echo "Usage: GetEvents.vbs ServerName EventLog EventID"
End If

Code: Named arguments

Set colNamedArguments = WScript.Arguments.Named

strServer = colNamedArguments.Item("Server")
strPacketSize = colNamedArguments.Item("PacketSize")
strTimeout = colNamedArguments.Item("Timeout")
Wscript.Echo "Server Name: " & strServer
Wscript.Echo "Packet Size: " & strPacketSize
Wscript.Echo "Timeout (ms): " & strTimeout
