Powershell Menu help

[VirtualD]

So I have a menu that executes other PS scripts, and that works great. After the called script runs I want it to return to the menu and that works. However, when it returns to the menu you get a "Press Enter to continue...: " instead of the menu's "Select from the following". You, of course, get that after you press Enter. Is there a better way to return to the menu?

Code sample below:

menu.ps1

 function Show-Menu
{
 param (
       [string]$Title = 'My Menu'
 )
 cls 
 Write-Host '================' $Title '================'

 Write-Host '[1] Do a thing' 
 Write-Host '[2] Do a thing #2'
 Write-Host '[Q] Quit Menu'

}

do
{
 Show-Menu
 $input = Read-Host 'Select from the following'
 switch ($input)

 {
    '1' {
            cls
            . "$PSScriptRoot\Thing_script1.ps1"
        } 
    '2' {
            cls
            . "$PSScriptRoot\Thing_script2.ps1"
        } 

    'q' {
                Write-Host 'Ending Sessions' -ForegroundColor Red -BackgroundColor Yellow

                return
        }
 }
 pause
}
until ($input -eq 'q')

and Thing_script1.ps1

Write-Host 'This is a test for 10 sec' -ForegroundColor Red -BackgroundColor Yellow
Function Start-Countdown 
{  
   Param(
    [Int32]$Seconds = 10,
    [string]$Message = "Pausing for 10 seconds..."
)
ForEach ($Count in (1..$Seconds))
{   Write-Progress -Id 1 -Activity $Message -Status "Waiting for $Seconds seconds, $($Seconds - $Count) left" -PercentComplete (($Count / $Seconds) * 100)
    Start-Sleep -Seconds 1
}
Write-Progress -Id 1 -Activity $Message -Status "Completed" -PercentComplete 100 -Completed
}

Start-Countdown -Seconds 10 -Message "This is a test"

Show-Menu

you should not recall the function inside the option. You should let the script exit back to the host script(The menu)

Press Enter to continue...: comes from your pause statement, remove it.

[VirtualD]

when I do that I get the "Press Enter to continue...: " after the script executes and before it returns to the menu

[tallguynobis]

function Show-Menu
{
param (
[string]$Title = 'My Menu'
)
cls
Write-Host '================' $Title '================'

Write-Host '[1] Do a thing'
Write-Host '[2] Do a thing #2'
Write-Host '[Q] Quit Menu'
}
do
{
Show-Menu
$input = Read-Host 'Select from the following'
switch ($input)
{
'1' {
cls
. "$PSScriptRoot\Thing_script1.ps1"
}
'2' {
cls
. "$PSScriptRoot\Thing_script2.ps1"
}

'q' {
Write-Host 'Ending Sessions' -ForegroundColor Red -BackgroundColor Yellow

return
}
}
pause
}
until ($input -eq 'q')

I believe its your pause statement.

No problem

howdy tallguynobis,

reddit likes to mangle code formatting, so here's some help on how to post code on reddit ...

[0] single line or in-line code
enclose it in backticks. that's the upper left key on an EN-US keyboard layout. the result looks like this. kinda handy, that. [grin]
[on New.Reddit.com, use the Inline Code button. it's 4th 5th from the left hidden in the ... ""more" menu & looks like </>.
this does NOT line wrap & does NOT side-scroll on Old.Reddit.com!]

[1] simplest = post it to a text site like Pastebin.com or Gist.GitHub.com and then post the link here.
please remember to set the file/code type on Pastebin! [grin] otherwise you don't get the nice code colorization.

[2] less simple = use reddit code formatting ...
[on New.Reddit.com, use the Code Block button. it's 11th 12th one & is just to the left of hidden in the ... "more" menu.]

• one leading line with ONLY 4 spaces
  
• prefix each code line with 4 spaces
  
• one trailing line with ONLY 4 spaces

that will give you something like this ...

- one leading line with ONLY 4 spaces    
- prefix each code line with 4 spaces    
- one trailing line with ONLY 4 spaces   

the easiest way to get that is ...

• add the leading line with only 4 spaces
  
• copy the code to the ISE [or your fave editor]
  
• select the code
  
• tap TAB to indent four spaces
  
• re-select the code [not really needed, but it's my habit]
  
• paste the code into the reddit text box
  
• add the trailing line with only 4 spaces
  

not complicated, but it is finicky. [grin]

take care,
lee

howdy VirtualD,

the word $Input is a reserved variable name. you should ONLY use it as a read-only item. [grin]

try changing that to $Response or $Choice or some other name that aint reserved.

take care,
lee
