It is a .NET method call so you need parens:

    $error.clear()

I am struggling with this. I have a value in seconds that I want to display in a label in HH:MM format. I have searched the internet for ages and found some answers, but either not fully understood them, or they seem like an odd way of doing what I want. If someone could help me out on this one that would be great! Bear in mind that I am new to this games so this question may seem like a really basic one to the more experienced out there.

I have a pattern (.png image 4x4px) and have to fill the layout with it.

Does anyone know how to do this? 

If I simply select the drawable as a background the image, it is stretched; instead it needs to be repeated along the x and y axis.

Is there a way to clear the $Error variable that tracks errors in a PowerShell session?

If so, how do you do it?

I have tried:
`$error.clear`

In the PowerShell ISE on Windows 7 and the $Error array is still populated.

I have a PowerShell 1.0 script to just open a bunch of applications. The first is a virtual machine and the others are development applications.  I want the virtual machine to finish booting before the rest of the applications are opened.

In bash I could just say `&quot;cmd1 &amp;&amp; cmd2&quot;`

This is what I&#39;ve got...

    C:\Applications\VirtualBox\vboxmanage startvm superdooper
        &amp;&quot;C:\Applications\NetBeans 6.5\bin\netbeans.exe&quot;



How to tell PowerShell to wait for each command to end before starting the next?

What is the simplest way to forcefully delete a directory and all its subdirectories in PowerShell? I am using PowerShell V2 in Windows 7.

I have learned from several sources that the most obvious command, `Remove-Item $targetDir -Recurse -Force`, does not work correctly. This includes a statement in the PowerShell V2 online help (found using `Get-Help Remove-Item -Examples`) that states:

&gt; ...Because the Recurse parameter in this cmdlet is faulty, the command uses the Get-Childitem cmdlet to get the desired files, and it uses the pipeline operator to pass them to the Remove-Item cmdlet...

I have seen various examples that use **Get-ChildItem** and pipe it to **Remove-Item**, but the examples usually remove some set of files based on a filter, not the entire directory.

I am looking for the cleanest way to blow out an entire directory, files and child directories, without generating any user warning messages using the least amount of code. A one-liner would be nice if it is easy to understand.




How to recursively delete an entire directory with PowerShell 2.0?

Given a list of items in PowerShell, how do I find the index of the current item from within a loop?

For example:

    $letters = { &#39;A&#39;, &#39;B&#39;, &#39;C&#39; }

    $letters | % {
      # Can I easily get the index of $_ here?
    }

The goal of all of this is that I want to output a collection using [Format-Table][1] and add an initial column with the index of the current item. This way people can interactively choose an item to select.

Get index of current item in a PowerShell loop

The following PowerShell script works if the resources are not there.

      Copy-Item $src_dir $dst_dir$agent_folder -recurse

But if the resources are there, it will say:

    +   Copy-Item &lt;&lt;&lt;&lt;  $src_dir $dst_dir$agent_folder -recurse
        + CategoryInfo          : ResourceExists: (C:\Users\Pac\Desktop\Agents\Agent0\lib:S
       tring) [Copy-Item], IOException
        + FullyQualifiedErrorId : DirectoryExist,Microsoft.PowerShell.Commands.CopyItemComm
       and

What do I have to add to the command so that it will unconditionally copy the files?

How is it possible to run a [PowerShell][1] script without displaying a window or any other sign to the user?

In other words, the script should run quietly in the background without any sign to the user.
