This page is really hosed. Here's the (more) correct script:

Param ($folder = "C:\test") #end Param

Function funLine($strIN) {

$strLine = "=" * $strIn.Length

Write-Host -ForegroundColor Yellow "`n$strIN"

Write-Host -ForegroundColor Cyan $strLine

} #end funLine

Function funMetaData() {

ForEach($sFolder in $folder) {

$a = 0

$objShell = New-Object -ComObject Shell.Application

$objFolder = $objShell.namespace($sFolder)

ForEach ($strFileName in $objFolder.Items()) {

funLine( "$($strFileName.Name)")

For ($a ; $a -le 266; $a++) {

If($objFolder.getDetailsOf($strFileName, $a)) {

$hash += @{ `

$($objFolder.getDetailsOf($objFolder.Items, $a)) =`

$($objFolder.getDetailsOf($strFileName, $a))

} #end hash

$hash

$hash.Clear()

} #end If

} #end For

$a=0

} #end ForEach

} #end funMetaData

# *** Entry Point ***

I looks like this page was hacked. Here is the fixed up code:

function funLine($strIN)

{

$strLine = "=" * $strIn.length

Write-Host -ForegroundColor Yellow "`n$strIN"

Write-Host -ForegroundColor Cyan $strLine

} #end funline

$sfolder = "C:\scripts"

$objShell = New-Object -ComObject Shell.Application

$objFolder = $objShell.namespace($sFolder)

foreach ($strFileName in $objFolder.items())

{funline "$($strFileName.name)"

for ($a ; $a -le 266; $a++)

{

if($objFolder.getDetailsOf($strFileName, $a))

{

$hash += @{ `

$($objFolder.getDetailsOf($objFolder.items, $a)) =`

$($objFolder.getDetailsOf($strFileName, $a))

} #end hash

$hash

$hash.clear()

} #end if

} #end for

$a=0

} #end foreach

Hello, when I run the DisplayMetaData.ps1 script specifying a folder that contains files I get the following error:

PS C:\> c:\script\displaymetadata.ps1 -folder c:\photos\tn

You cannot call a method on a null-valued expression.

At C:\script\displaymetadata.ps1:16 char:44

+ foreach ($strFileName in $objFolder.items <<<< ())

+ CategoryInfo : InvalidOperation: (items:String) [], RuntimeException

+ FullyQualifiedErrorId : InvokeMethodOnNull

Any suggestions on how to debug this? My guess is that something is going wrong with "$objShell = New-Object -ComObject Shell.Application" in my environment. Thanks.

Found the problem...

On line 2: change "funLine($strIN)" to "function funLine($strIN)"

On Line 8: change "funMetaData()" to "function funMetaData()"

after line 36: "# *** Entry Point ***", append a new line 37: "funMetaData"

Hey Scripting Guy, can you please explain the following in more detail? Where is the loop? It looks like it is only processing one line, but it is not? How does it fill hash table?

$hash += @{ `

$($objFolder.getDetailsOf($objFolder.items, $a)) =`

$($objFolder.getDetailsOf($strFileName, $a))

} #end hash

When I try to run this, I get the following error. Why?

PS D:\Users\Dan> D:\_Docs_Dan\P\programming\PowerShell\DisplayMetaData.ps1

An expression was expected after '('.

At D:\_Docs_Dan\P\programming\PowerShell\DisplayMetaData.ps1:8 char:13

Your post was very helpful, but now I would like to change the value of the metadata. can you help. I do not see a method to change the data just to get it. here is the code I have so far.

$sh = new-object -com shell.application

$folder = $sh.namespace("C:\windows")

if ($folder) {

$folderitem = $folder.parsename("clock.avi")

if ($folderitem) {

$name = $folder.getdetailsof($folderitem,0)

}

If ($name) {

"The file c:\windows\clock.avi is:"

"{0,-20} {1}" -f "File Name", $name
