    <p>In the code blocks below, I'm trying to run Get-MyCmdlet in 3 separate threads, each of which opens a google page if the Get-MyCmdlet did not give anything.</p> <p>The Get-MyCmdlet is fairly simple, the only thing it does is WriteObject("hello world"); (defined in the c# code).</p> <p>However the script always opens up a google page, unless I change the Get-MyCmdlet to Get-Host(which is a system default cmdlet). </p> <p>Is it because the custom cmdlets are not supporting multi-threading? Any help will be greatly appreciated!</p> <p>The cmdlet: </p> <pre><code>[Cmdlet(VerbsCommon.Get, "MyCmdlet ")] public class GetMyCmdlet : Cmdlet { protected override void ProcessRecord() { WriteObject("hello world"); } } </code></pre> <p>the script:</p> <pre><code>$ScriptBlock = { $result = Get-MyCmdlet if (!$result) {[System.Diagnostics.Process]::Start("http://www.google.com")} $name = ($result | get-member)[-1].name $result = $result.$name return $result } </code></pre> <p>....</p> <pre><code>$threads = 3 for ($i = 0; $i -lt $threads) { $running = @($jobs | Where-Object {$_.State -match 'Running'}) Write-Host $running.length if ($running.length -lt $threads) { $jobs += Start-job -ScriptBlock $ScriptBlock $i = $i + 1 } else { get-job | receive-job $finished = @($jobs | Where-Object ($_.State -match 'Completed')) if ($finished) { $finished.getType() foreach($job in $finished) { Receive-Job -keep $job | Out-File "Output$.txt" $i = $i + 1 $finished.Remove($job) Remove-Job -job $job } } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
