CopyHere ignores vOptions on Windows PowerShell
Lee@discussions.microsoft.com Leonard Lee
Does anyone know why the CopyHere ignores vOptions?
I'm using Windows PowerShell 2 CTP2, Windows XP, and Microsoft .NET
Framework 3.5.
Related information available below. However, no solution given.

Quoted from Gerald Gibson Jr:
What I have found is the vOptions parameter does not work. This is what led
me to making this article in the first place. I wanted to use the vOptions
paramter '4' to tell it to NOT display a dialog box at all... but it simply
does not work. To get around this I used the console app approach where I can
tell it to not show any output.

I'm attempting to use the CopyHere Shell32 function through a C#
application. I'm compilign with VS2005 latest SP at the time of writing and
newest .NET 2 on a WinXP SP2 machine and attempting to run the code on a
Win2003 Server SP2.
The line of code specifies for vOptions 20 which is
* 4 Do not display a progress dialog box.
* 16 Respond with "Yes to All" for any dialog box that is displayed.
DestFlder.CopyHere(items, 20);
Well it seems to be ignoring the options. It shows the decompression window
and then prompts to overwrite every file. Another individual here has
replicated this as well;

Am I just doing it wrong using the value 20, or is it ignoring the option?

Below are my Windows PowerShell script.
---------------------------------------------------------------------------------
function Extract-Zip #Usage: Extract-Zip C:\Temp\Archive.zip
c:\Temp\Destination
{
param([string]$zipfilename, [string] $destination)
if(test-path($zipfilename))
{
[System.Int32]$yesToAll = 16
$shellApplication = new-object -com shell.application
$zipPackage = $shellApplication.NameSpace($zipfilename)
$destinationFolder = $shellApplication.NameSpace($destination)
#Copy one file by one file
# foreach ($item in $zipPackage.Items())
# {
# $destinationFolder.CopyHere($item,$yesToAll)
# }
#Copy the whole folder
$destinationFolder.CopyHere($zipPackage.Items(),$yesToAll)
}
}
$source = "C:\Scripts\MicrosoftSysInternalsDownloads\Packages\Autoruns.zip"
$dest = "C:\Temp"
Extract-Zip $source $dest

Thanks in advance.

This works for me without a problem:
[System.Int32]$yesToAll = 16
$shellApplication = new-object -com shell.application
$test1 = $shellApplication.NameSpace("D:\Scripts\temp\test1")
$test2 = $shellApplication.NameSpace("D:\Scripts\temp\test2")
$test2.CopyHere($test1,$yesToAll)
BTW, if you already use powershell code, why don't you use PowerShell's native
commands:
# copies the entire contents of the $test1 directory into the $test2 directory
and overwrites the files
PS > copy-item $test1 -destination $test1 -recurse -force

Thanks for the reply.
The CopyHere from Shell.Application object ignores the vOptions to force
override.
The problem here is that Copy-Item currently cannot work on the
Shell.Application folder objects.
#Copy the whole folder
#$destinationFolder.CopyHere($zipPackage.Items(),$yesToAll)
Copy-Item $zipPackage.Items() -Destination $destinationFolder -Recurse -Force
The Copy-Item code above will throw us an exception as shown below.
System.__ComObject System.__ComObject System.__ComObject System.
__ComObject' because it does not exist.
Thanks in advance.

Try to add 'self.path' to each shellNameSpace folder. copy-item expects a
path on the special folder.
Again, if you already using powershell in your solution, make it powershell
only, its only one line of code :)
$desktop = 0
[System.Int32]$yesToAll = 16
$shellApplication = new-object -com shell.application
$dt = $shellApplication.NameSpace($desktop).self.path
$destinationFolder = $shellApplication.NameSpace("d:\scripts\temp\test2").self.path
#$destinationFolder.CopyHere($dt,$yesToAll)
copy-item $dt -destination $destinationFolder -recurse -force

Thanks for your fast reply.
The problem I faced here is to extract contents in the zip file into a
folder, which it will also overwrite any files contained within that folder.
Do you have any "Windows PowerShell" way to extract zip file and force
overwrite of files on the destination folders?
I did tried your advices. It copied the Zip file only, but never extract the
contents out into the destination folder with force overwrite. Below are my
modified script...
------------------------------------------------------------------------------------------------
function Extract-Zip #Usage: Extract-Zip C:\Temp\Archive.zip
c:\Temp\Destination
{
param([string]$zipfilename, [string] $destination)
if(Test-Path($zipfilename))
{
[System.Int32]$yesToAll = 16
$shellApplication = New-Object -com Shell.Application
# $zipPackage = $shellApplication.NameSpace($zipfilename)
$zipPackage = $shellApplication.NameSpace($zipfilename).Self.Path
# $destinationFolder = $shellApplication.NameSpace($destination)
$destinationFolder =
$shellApplication.NameSpace($destination).Self.Path
#Copy one file by one file
# foreach ($item in $zipPackage.Items())
# {
# $destinationFolder.CopyHere($item,$yesToAll)
# }
#Copy the whole folder
# $destinationFolder.CopyHere($zipPackage.Items(),$yesToAll)
# Copy-Item $zipPackage.Items() -Destination $destinationFolder -Recurse
-Force
Copy-Item $zipPackage -Destination $destinationFolder -Recurse
-Force #Copy the whole zip file.
}
}
$source = "C:\Scripts\MicrosoftSysInternalsDownloads\Packages\Autoruns.zip"
$dest = "C:\Temp"
------------------------------------------------------------------------------------------------
Thanks in advance.

Add the -force parameter to move-item (if necessary)
dir $files.self.path | Move-Item -Destination $destinationFolder.self.path
-force

Thanks for the great solution. Definitely the MVP for Windows PowerShell.
I think this solution will draw more people to use Windows PowerShell
compared to other conventional methods on force overwrite of files after
extracted from a zip file.
Thanks for the advice and help!
Let me share my last modified script on extracting zip content and force
overwrite on the destination folder.
---------------------------------------------------------------------------------
function Extract-Zip
{
param([String]$zipFileName, [String] $destination)
if(Test-Path $zipFileName)
{
$shellApplication = New-Object -Com Shell.Application
$zipPackage = $shellApplication.NameSpace($zipFileName)
$destinationFolder = $shellApplication.NameSpace($destination)
# Create temp directory to store the files
$tmpName = [System.IO.Path]::GetRandomFileName()
$tmpDir = New-Item -Type Directory -Path "$Env:Temp" -Name $tmpName -Force
$files = $shellApplication.NameSpace($tmpDir.fullname)
$files.CopyHere($zipPackage.Items())
# Move the files to $destinationFolder
Dir $files.Self.Path | Move-Item -Destination
$destinationFolder.Self.Path -Force
}
}
$source = "C:\Scripts\MicrosoftSysInternalsDownloads\Packages\Autoruns.zip"
$destination = "C:\Temp"
Extract-Zip $source $destination
---------------------------------------------------------------------------------
Hope this helps.

There is an add-on zip library that may make more sense for some
powershell scripters:
