When you use Select-Object, you’re still producing a complex object with properties, as you’ve seen.Get-ADComputer -filter * | Select -Expand Name | My-FunctionIs one option. Extract (expand) the...

Reply To: Save the output of powershell script
I’m not sure what you mean by “get the output in a single file within the script”. Do you mean all of the output should wind up in a single text file? Or do you mean all of the code should be in a...

Your OpenRemoteRegistryKey function has a bug. In both places where you’re calling the function recursively, you should assign the result to $reg; as written, you’re just throwing the result away (and...

Actually, now that I think about it, my description of the bug probably wasn’t accurate. It wasn’t that you were throwing away the results of the recursive call (because PowerShell should still write...

Here is code I use. The if($Host.Name…) will start the transcripting only if not running in the ISE, since ISE does not support transcript files. $now=Get-Date -format "yyyyMMdd_HHmmss"if ($Host.Name...

$env can only change the path for the CURRENT process. That’s a Windows thing. Take a look at the discussion at http://powershell.org/wp/forums/topic/invoke-command-to-set-psmodulepath/.

Simple question. Guess I could test it and see what happens, but right now (honestly) I barely have time to post this question. I’m getting tired of 70-hour weeks! Can a catch block contain it’s own...

Both of the modules I posted can do that, though the second one is easier to use (requires fewer changes to your existing script): # At beginning of script (either in the Begin block, if you're using...

Start-Transcript is another option. The main disadvantages of that command versus the PSLogging module are that Start-Transcript doesn’t work from the ISE, and you can only have one transcript going...

Rather than updating the PSModulePath variable on all your machines, a possible alternative is to use a full path to the module in the Import-Module command of whatever scripts are using it. I haven’t...

When using ConvertTo-HTML with no input object and only -body and -head tags, the output contains a trailing set of empty <table> tags. This causes some minor graphical glitching when emailing...
View ArticleReply To: ConvertTo-HTML inserts empty table tag
There is no option to do so, no. It’d be listed in the command’s help if there was. I’d say a workaround might be to pass the string (non-breaking space) to -InputObject, but I haven’t tried that. I...

This is how you “swap” two values. $b[$_] takes on the value of $b[$i] $b[$i] takes on the original value of $b[$_]

The section you highlighted ($b[$_],$b[$i] = $b[$i],$b[$_]) will swap two values in array $b: the one at index $_ with the one at index $i.Also for reference if others are curious, this snippet comes...
