Vista - Command & variable substitution

Hello I have the following problem while creating a script which
contains the following line:

Script line:
get-wmiobject -class $strWMIClassName

Error description:
At xxx 1:74 char:15
+ get-wmiobject <<<< -class $strWMIClassName

As you can see the var is not substituted. I have tried all the ways I
do know from unix shells and so on how to substitute line $($var), `
$var`, ${var}....

Has anyone of you an idea how to solve this problem?

Thanks

Chris

It works fine on v1 & v2

$strWMIClassName = "win32_process"
get-wmiobject -class $strWMIClassName


You didn't include the $strWMIClassName assignment in your post, check that
it's not $null

I have verified that the var is not null. it contains as example the
value Win32_Fan...

here my whole script...


###
# Script options

#
$boolDebug = $true

#
$strConfigFile = ".\WMIList.config"

#
$strCommentSign = "#"

#
$strDelimSign = ";"

# End script options
###

$intConfigCounter = 0

# Clear the screen
cls

# Read the configuration and exclude the comments
$strConfig = cat $strConfigFile | where
{$_.StartsWith($strCommentSign) -eq $false -and $_.Length -gt 0}

# Iterate all config lines (entries)
while ($intConfigCounter -lt $strConfig.Length) {

# Get the description of the current WMI Class out of the
config
# For this need all signs after the delim sign are stored
$strWMIClassDescription =
$strConfig[$intConfigCounter].Substring($strConfig[$intConfigCounter].IndexOf($strDelimSign)
+1)

# DEBUG
echo $strWMIClassDescription

# Get the name of the current WMI Class out of the config
# For this need remove the description, caused by this just
the name will return
$strWMIClassName =
$strConfig[$intConfigCounter].Remove($strConfig[$intConfigCounter].IndexOf($strDelimSign)
+1, $strWMIClassDescription.Length)

# DEBUG
echo $strWMIClassName
get-wmiobject -class $strWMIClassName

# Raise counter
$intConfigCounter = $intConfigCounter + 1

} # end while iterate all config entries

The script access a config file which contains as example:

# Comment
Win32_Fan;Blubb
Win32_Share;Blubber

Does this work?

$strWMIClassName = "win32_process"
get-wmiobject -class $strWMIClassName



If so, check your script. What's the output of echo $strWMIClassDescription
each iteration?

I suggest to download PowerGUI. It has a built-in script debugger you can
use to find what's wrong.
You can download it at:

BTW, why all the description and comments stuff when all you need is to query
with WMI?
Woudn't it be much simpler to store your WMI class names in CSV file and
avoid the parsing?

Can you try this:

############ .\WMIList.config ###########

Win32_Fan;Blubb
#Win32_Share;Blubber
Win32_Share;Blubber
#Win32_Share;Blubber

############ .\WMIList.config ###########



cat C:\Scripts\temp\WMIList.config | where {$_.substring(0,1) -ne "#"} |
foreach {
$strWMIClassName = $_.substring(0,$_.indexOf(";"))
$strWMIClassName
#get-wmiobject -class $strWMIClassName
}


# output #
Win32_Fan
Win32_Share
