How to return PowerShell variable to VBScript - powershell

Question

I have a vbscript to call a PowerShell script in hopes of returning the PowerShell output to an HTA (HTML Application) GUI. Right now I just want to see if I can return the PowerShell output into a MsgBox in the vbscript. I am not having much luck with this.
VBScript Code:
Set shell = CreateObject("WScript.Shell")
return = shell.Run("powershell.exe -executionpolicy bypass -noprofile -file pathToScript\PowerShellToVBA.ps1", , true)
MsgBox return
PowerShell Code:
Clear-Host
return 50
I am trying to keep the return value extremely simple until it works. With this, I would expect the MsgBox to return '50', however it is returning '0' instead. Any ideas what im doing wrong?

Answer 1

I think you just want the exit command to get the return value:
VBScript
pscommand = ".\myscript.ps1; exit $LASTEXITCODE"
cmd = "powershell.exe -noprofile -command " & pscommand
Set shell = CreateObject("WScript.Shell")
rv = shell.Run(cmd, , True)
MsgBox "PowerShell returned: " & rv, vbSystemModal
Powershell
exit 50;
EDIT #1
Or if you want to grab a return string:
VBScript
pscommand = ".\myscript2.ps1"
cmd = "powershell.exe -noprofile -command " & pscommand
Set shell = CreateObject("WScript.Shell")
Set executor = shell.Exec(cmd)
executor.StdIn.Close
MsgBox executor.StdOut.ReadAll
Powershell
Write-Output '***SUCCESS***';

Answer 2

As a followup, using the VBScript above to output a string. In your PS script if you use eg
write-host "Error: some specific thing happened"
to set various error or success messages the
MsgBox executor.StdOut.ReadAll
will display all of what you write via write-host.
A helpful way to display the outcome of the PS script to your VBA user.
Just FYI.
