Hi,
I give up 
.
I found this script which provides a menu in Powershell (no popups). I get all of my hosts, then run the function(s).
At the end of the script after I have chose the one I want, I am trying to find/set a variable so that I can then use the host name for my next command.
I cannot figure out how to do this, as I do not understand what happens to my choice (which I think is in the variable $choice), but $choice ends up empty when I check it manually afterward.
Can someone please help me? At the bottom you will see my gathering of the hosts and calling of the function.
Thanks!
function Write-Choice {
param($prompt, $choice)
write-host -n "["
write-host -n -f yellow $prompt
write-host "]", $choice
Write-Output $prompt
}
function Get-Selection {
param(
[Parameter(Mandatory=$true,ValueFromPipeline=$true,Position=0,HelpMessage="Choices")]
[Object]
$choice,
[Parameter(HelpMessage="Intro message")]
[string]
$introMessage="Choose from the following options:",
[Parameter(HelpMessage="Prompt message")]
[string]
$prompt="Select an option",
[Parameter(HelpMessage="Window size")]
[Int]
$windowSize=10
)
$currentWindow = 0
$maxWindow = [Math]::Floor($choice.length / $windowSize)
while ($true) {
Clear-Host
$start = $currentWindow*$windowSize
$thisWindowSize = [Math]::Min($windowSize, $choice.length - $start)
if ($introMessage) {
write-host -fore yellow $introMessage
}
$choices = @()
for ($i = 1; $i -lt $thisWindowSize + 1; $i++) {
$choices += Write-Choice $i $choice[$start + $i - 1]
}
if ($currentWindow -gt 0) {
$choices += Write-Choice "P" "Previous Page Of Choices"
}
if ($currentWindow -lt $maxWindow) {
$choices += Write-Choice "N" "Next Page Of Choices"
}
while ($true) {
$input = read-host $prompt
if ($choices -notcontains $input) {
continue
}
if ($input -eq "N") {
$currentWindow++
break
} elseif ($input -eq "P") {
$currentWindow--
break
} else {
Write-Output $choice[$start + [int]$input - 1]
return
}
}
}
}
# Get the hosts
$choosehost = get-vmhost | get-view | select name
# Call the function
Get-Selection $choosehost
