Here is an example of how to dynamically assign images to a listview. Run it then analyze how the imagelists are built.

You can also assign at design time from files and they will be encoded into the script.

Sorry. Try it this way.

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. function STATUS {
2.    
3.     Get-ADComputer -Filter * -SearchBase 'OU=DOMUSERS,DC=DOM,DC=LOCAL' |
4.         ForEach-Object {
5.             $item1 = New-Object System.Windows.Forms.ListViewItem
6.             $item1.Text = $_.Name
7.             $item1.Name = $_.Name
8.             $item1.SubItems.Add('n/a')
9.             $item1.SubItems.Add('n/a')     
10.             $listview2.Items.Add($item1)
11.             if(Test-Connection -ComputerName $_.dnshostname -Count 1 -Quiet){
12.                 $item1.ImageIndex = 0
13.                 $item1.SubItems[1].Text = 'Online'
14.                 $item1.SubItems[1].ForeColor = 'Green'
15.                 $ProtectionStatus = Invoke-Command -ScriptBlock { (Get-BitLockerVolume).ProtectionStatus } -ComputerName $_.name -Credential $Global:DomainCredentials
16.                 if ($ProtectionStatus -match 'On') {
17.                     $item1.SubItems[2].Text = 'On'
18.                     $item1.UseItemStyleForSubItems = $true;
19.                 }else{
20.                     $item1.SubItems[2].Text = 'Off'
21.                     $item1.UseItemStyleForSubItems = $false;
22.                     $item1.SubItems[2].ForeColor = 'DarkRed'
23.                 }          
24.             }else{
25.                 $item1.ImageIndex = 1
26.                 $item1.SubItems[1].Text = 'Offline'
27.                 $item1.SubItems[1].ForeColor = 'Red'
28.             }
29.         }
30. }

Here is another way to do thos:

Code: [Select all] [Expand/Collapse] [Download] (Untitled.ps1)

1. function STATUS {
2.    
3.     Get-ADComputer -Filter * -SearchBase 'OU=DOMUSERS,DC=DOM,DC=LOCAL' |
4.         ForEach-Object {
5.        
6.             $item1 = New-Object System.Windows.Forms.ListViewItem
7.             $listview2.Items.Add($item1)
8.             $item1.Text = $_.Name
9.             $item1.Name = 'Computer'
10.             $status = $item1.SubItems.Add('n/a')
11.             $bitlocker = $item1.SubItems.Add('n/a')    
12.             $item1.UseItemStyleForSubItems = $false
13.        
14.             if(Test-Connection -ComputerName $_.dnshostname -Count 1 -Quiet){
15.                 $item1.ImageIndex = 0
16.                 $status.Text = 'Online'
17.                 $status.ForeColor = 'Green'
18.                 $ProtectionStatus = Invoke-Command -ScriptBlock { (Get-BitLockerVolume).ProtectionStatus } -ComputerName $_.name -Credential $Global:DomainCredentials
19.                 if ($ProtectionStatus -match 'On') {
20.                     $bitlocker.Text = 'On'
21.                 }else{
22.                     $bitlocker.Text = 'Off'
23.                     $bitlocker.ForeColor = 'DarkRed'
24.                 }          
25.             }else{
26.                 $item1.ImageIndex = 1
27.                 $status.Text = 'Offline'
28.                 $status.ForeColor = 'Red'
29.             }
30.         }
31. }

You can't add images to a list before you have crated them. You can add them with a keyname and use ImageKey to reference the image.

don't worry

this is the result near the solution but not complete: only the second pc is colored green o red, take a look about VM8

[jvierra]

Without seeing the code that did this I cannot comment.

[ramses147]

The code is your first good solution:
