Press any key to continue using Powershell

Hi,

This is the code in powershell that can be used as function where you want to repeat the tasks or present user with some kind of choice.

 

# Clear screen to clear the trash off the screen
clear-host


# Using here string to display Menu
$menu = @"
Menu
--------------------
Select your options
1
2
3
4
5
6
7
8
0 : Press 0 to Exit

"@

write-host $menu
Function Pause ($Message = "Press any* key to continue . . .Well I don't mean all :) ") {
    If ($psISE) {
        # The "ReadKey" functionality is not supported in Windows PowerShell ISE.

        $Shell = New-Object -ComObject "WScript.Shell"
        $Button = $Shell.Popup("Click OK to continue.", 0, "Script Paused", 0)

        Return
    }

    Write-Host -NoNewline $Message
   
    # Secret codes :) you don't want to continue when press shift key alt etc etc
   
    $Ignore =
        16,  # Shift (left or right)
        17,  # Ctrl (left or right)
        18,  # Alt (left or right)
        20,  # Caps lock
        91,  # Windows key (left)
        92,  # Windows key (right)
        93,  # Menu key
        144, # Num lock
        145, # Scroll lock
        166, # Back
        167, # Forward
        168, # Refresh
        169, # Stop
        170, # Search
        171, # Favorites
        172, # Start/Home
        173, # Mute
        174, # Volume Down
        175, # Volume Up
        176, # Next Track
        177, # Previous Track
        178, # Stop Media
        179, # Play
        180, # Mail
        181, # Select Media
        182, # Application 1
        183  # Application 2

    While ($KeyInfo.VirtualKeyCode -Eq $Null -Or $Ignore -Contains $KeyInfo.VirtualKeyCode) {
        $KeyInfo = $Host.UI.RawUI.ReadKey("NoEcho, IncludeKeyDown")
    }

    Write-Host
}


# using do while loop to do switch case annoyance

do {

if($a)
 {
    clear-variable a
  }
$a = read-host "Select your option"

switch ($a)
    {
      
        1 {write-host -ForegroundColor RED "The color is red."; Pause;}
        2 {write-host -ForegroundColor DARKBLUE "The color is blue."; Pause;}
        3 {write-host -ForegroundColor GREEN "The color is green."; Pause;}
        4 {write-host -ForegroundColor YELLOW "The color is yellow."; Pause;}
        5 {write-host -ForegroundColor DarkYellow "The color is orange."; Pause;}
        6 {write-host -ForegroundColor Magenta "The color is purple."; Pause;}
        7 {write-host -ForegroundColor Cyan "The color is pink."; Pause;}
        8 {write-host -ForegroundColor Gray "The color is brown."; Pause;}
        0 {write-host "Exiting..."; Exit;}
  default {"The color could not be determined."; Pause;}
     }
    }
     while(!($a -eq 'null'))

 

Hope this will be helpfully in some ways.
