VBScript Tutorials - Herong's Tutorial Examples

∟WSH (Windows Script Host)

∟Running VBScript Code Files

Now let's write and run our first VBScript with WSH.

Create a VBScript example file, Hello_Echo.vbs, with the following statements:

'  Hello_Echo.vbs
'- Copyright (c) 2015, HerongYang.com, All Rights Reserved.

   Set oArgs = WScript.Arguments
   If oArgs.Length = 0 Then WScript.Echo "Hello wolrd!"
   For Each sArg In oArgs
      WScript.Echo "Hello " & sArg
   Next

Run Hello_Echo.vbs in many ways in a command window:

C:\herong>cscript Hello_Echo.vbs Herong Tom
Hello Herong
Hello Tom

C:\herong>wscript Hello_Echo.vbs Herong Tom
(Dialog box showing "Hello Herong")
(Dialog box showing "Hello Tom")

C:\herong>cscript //h:cscript
The default script host is now set to "cscript.exe".

C:\herong>Hello_Echo.vbs Herong Tom
Hello Herong
Hello Tom

C:\herong>cscript //h:wscript
The default script host is now set to "wscript.exe".

C:\herong>Hello_Echo.vbs Herong Tom
(Dialog box showing "Hello Herong")
(Dialog box showing "Hello Tom")

Noticed that Hello_Echo.vbs can be executed in 3 ways:

• "cscript Hello_Echo.vbs ..." - Using host cscript.exe to execute.
• "wscript Hello_Echo.vbs ..." - Using host wscript.exe to execute.
• "Hello_Echo.vbs ..." - Using the default host, cscript.exe or wscript.exe. You can change the default host using the "cschipt //h:..." command.
