I am trying to call Powershell with the Exec method of the WshShell object. I am writing the script in JScript, but I have reproduced the problem in VBScript as well. Both of the following short test scripts will cause WSH to hang indefinitely: test.js <pre><code>var shell = new ActiveXObject("WScript.Shell"); WScript.Echo(shell.exec("powershell -Command $Host.Version; Exit").StdOut.ReadAll()); </code></pre> test.vbs <pre><code>dim shell set shell = CreateObject("WScript.Shell") WScript.Echo shell.exec("powershell -Command $Host.Version; Exit").StdOut.ReadAll </code></pre> Am I doing something wrong, or am I running into or a limitation/incompatibility? The Run method works very well, but I need to capture output, which it's not capable of doing. Edit: I forgot to mention that my platform is Windows 7 Pro, 64-bit with PowerShell 3. I've tested on Windows XP with PowerShell 1 as well. Edit 2: I've updated the test scripts that I'm running to fit with x0n's answer. Unfortunately, I'm still having trouble. Here are my current tests: test.js: <pre><code>var shell = new ActiveXObject("WScript.Shell"); WScript.Echo(shell.exec('powershell -noninteractive -noprofile -Command "& { echo Hello_World ; Exit }"').StdOut.ReadAll()); </code></pre> test.vbs: <pre><code>dim shell set shell = CreateObject("WScript.Shell") WScript.Echo shell.exec("powershell -noninteractive -noprofile -Command ""& { echo Hello_World ; Exit }""").StdOut.ReadAll </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.
