Question

Either I do not understand the documentation on MSDN or the documentation is incorrect.

if($user_sam -ne "" -and $user_case -ne "")
{
    Write-Host "Waaay! Both vars have values!"
}
else
{
    Write-Host "One or both of the vars are empty!"
}

I hope you understand what I am attempting to output. I want to populate $user_sam and $user_case in order to access the first statement!

Answer 1

You can simplify it to

if ($user_sam -and $user_case) {
  ...
}

because empty strings coerce to $false (and so does $null, for that matter).
