Use variable in WScript.Run

Question

The following works fine:

VBScript

Script = "C:\Users\bob\Downloads\Logon scripts\Script.ps1"
Dim oSHELL
Set oSHELL = CreateObject("WScript.Shell")
oSHELL.Run "powershell.exe -ExecutionPolicy Bypass -NoLogo -File ""C:\Users\bob\Downloads\Logon scripts\Script.ps1""", 0, True
Set oSHELL = Nothing

When I'm trying to put the path to the script in a variabla, it's not working:

oSHELL.Run "powershell.exe -ExecutionPolicy Bypass -NoLogo -File ""Script""", 0, True
oSHELL.Run "powershell.exe -ExecutionPolicy Bypass -NoLogo -File""" & Script & """", 0, True

Script.ps1

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.MessageBox]::Show("Test MessageBox", "Information")

How is it possible to have WScript use the variable correctly?

Answer 1

Apart from a slight typo in your second example (missing space after -File) Currently, it will execute like

powershell.exe -ExecutionPolicy Bypass -NoLogo -File"C:\Users\bob\Downloads\Logon scripts\Script.ps1"

and produce an error, which you haven't documented in the question.

I can't see why this wouldn't work.

Dim oSHELL: Set oSHELL = CreateObject("WScript.Shell")
Dim Script: Script = "C:\Users\bob\Downloads\Logon scripts\Script.ps1"
Call oSHELL.Run("powershell.exe -ExecutionPolicy Bypass -NoLogo -File """ & Script & """", 0, True)

It's equivalent to;

powershell.exe -ExecutionPolicy Bypass -NoLogo -File "C:\Users\bob\Downloads\Logon scripts\Script.ps1"
