    <p>I have: C#.NET using the PowerShell() object, calling one powershell script, which calls another.</p> <p>C#->Powershell(parent)->Powershell(child). [capture verbose: parent works, child does not].</p> <p>My code CORRECTLY grabs/streams Verbose from the first (parent) powershell script. However, I have not been able to get the Verbose stream from the (child) powershell script. Note: if I call hello1.ps directly, it works (because it's not the child).</p> <p>(I've read numerous articles / searches / other stackoverflow answers. Mostly they talk about how to capture it once, or recommend the `$verbosepreference). </p> <p>Solutions? Thanks!</p> <pre><code> public void Run() { var ps = PowerShell.Create(); ps.AddScript("`$verbosepreference='continue'"); // &lt;-- tried this, no effect. ps.AddScript("set-location \"" + dir + "\""); ps.AddScript(System.IO.File.ReadAllText("./hello-caller.ps1")); ps.AddParameter("name", "A"); ps.AddParameter("where", "B"); var output = new PSDataCollection&lt;PSObject&gt;(); output.DataAdded += Verbose_DataAdded; var results = ps.BeginInvoke&lt;PSObject, PSObject&gt;(null, output, null, AsyncInvoke, null); } void Verbose_DataAdded(object sender, DataAddedEventArgs e) { var source = ((PSDataCollection&lt;PSObject&gt;) sender); var msg = source[e.Index].ToString(); Console.WriteLine(msg); } --- hello-caller.ps1 --- Param( [string]$name, [string]$where ) ./hello.ps1 $name $where --- hello.ps1 --- Param( [string]$name, [string]$where ) $i = 0 while ($i -le 30) { Write-Verbose "Hello " $name " from " $where Start-Sleep -s 1 $i++ } return true </code></pre>

    1. COJust out of curiousity, does it work if you run the child script in the parent scope (. ./hello.ps1 $name $where) ?

    2. COmj: yes, we may have crossed edits, but (see above), when I run it directly, it works just fine. In fact, that was my scenario until I realized I needed to cover child processes - then I saw it failed when I moved it down one level.

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.
