Include other files in VBScript

Have you ever wanted to include another .vbs file with all your common functions in a script?

Many people I have met thought it wasn’t possible.

But it is actually pretty easy to do with “ExecuteGlobal”

to make it even easier, I have created a small function which you can put in your scripts and use a simple


I have made 2 small example scripts to show you how to use it:


This file could be a shared file with all your common functions such as Log writer.


Then everytime you create a script you include the function and make sure to include the other vbs files in the beggning of the script.

Now you have access to all the functions from the other scripts, from inside your new script!

and the next time the management tells you to change the Log Format to a different date/time format, so simular. You just have to change the function in the shared file, instead of editing all your scripts!

But beware not to corrupt the shared file, cause it will make all your scripts fail 😉

Merry x-mas!

    Hi Jacob,
    why don’t you use build-in feature of .wsf files?
    There’s no problem using .vbs include files:

    Sub Test
    sText = “Huhu”
    End Sub


    Call Test ‘ you can treat subs or functions from include.vbs as if they exist in sampe.wsf
    MsgBox sText

    I have posted this on another forum but may be useful here as well :

    “Hi all,

    I know this is an old thread but I post my answer anyway so others can learn what I have learnt about VBS and WSF files by “trial and error” :

    So to have the same functionality as in other languages you can create one WSF file and include all of your VBS libs there, including the main program.

    Something like this :

    ‘ Here we call the main program

    In “Constants.vbs” collect all constants you want to use later and in the other VBS files define your functions. In your main program file “MainProgram.vbs” create a Sub called “MainProgram()” and write your program there.
    In this sub you can use all of the constants and functions defined in the other VBS files.

    For example :

    sub MainProgram()
    ‘ Local variables
    Dim strMessage, strSendTo, strSubject
    ‘ OpenFile is a function from FileFunctions.vbs
    strMessage = OpenFile(“C:Msgmessage.html”)
    strSendTo = “”
    strSubject = “Daily report – ” & date
    ‘ SendMessage is a function from SendMail.vbs
    ‘ cFrom and cServer are constants from Constants.vbs
    SendMessage(cFrom, strSendTo, strSubject, strMessage, cServer)
    ‘ Logger is a function from LoggingFunctions.vbs
    Logger(“Daily report sent – ” & now())
    end sub

    Hope you get the idea and I could help some people write better VBS apps 🙂 “
