Powershell run message box from cmd

Question

I am trying to achieve the following :

I need to run from batch file psh script , but not from file , solo de command line. I've tried the following code from ps console and it works , but when passing this from cmd - not.

powershell.exe -ExecutionPolicy Bypass -Command {[System.Reflection.Assembly]::LoadWithPartialName('System.Windows.Forms'); [System.Windows.Forms.MessageBox]::Show('We are proceeding with next step.')}

Can anyone pls help to figure out la problema ? Gracias.

Answer 1

Switch {brackets} for "quotes":

@powershell.exe -ExecutionPolicy Bypass -Command "[System.Reflection.Assembly]::LoadWithPartialName('System.Windows.Forms'); [System.Windows.Forms.MessageBox]::Show('We are proceeding with next step.')"

(also added the @ for echo off)
