WMI - get single value

[cherdeg]

Hi,

For a management tool I need to query several different values from WMI. Point is, I have to do that from Linux. Yes, I know, this is AutoIT, and it's for Windows. But you guys have proven to be a most often very helpful and professional community, so I thought, let's just ask...you.

On Windows, if I query WMI from VB or AutoIt, I usually do something like this:

Local $wbemFlagReturnImmediately= 0x10
Local $wbemFlagForwardOnly      = 0x20
Local $h_wbemFlags              = $wbemFlagReturnImmediately + $wbemFlagForwardOnly
$s_ComputerName                 = "localhost"
$o_WMIService                   = ObjGet("winmgmts:\\" & $s_ComputerName & "\root\CIMV2")
$o_LogicalDiskC                 = $o_WMIService.ExecQuery("SELECT Size FROM Win32_LogicalDisk WHERE Description = 'Local Fixed Disk' AND Name = 'C:'", "WQL", $h_wbemFlags)

If IsObj ($o_LogicalDiskC) Then
    For $o_item in $o_LogicalDiskC
        ConsoleWrite(@CRLF & $o_item.Size & " Bytes - " & Round($o_item.Size /1024 /1024 /1024, 2) & " GBytes" & @CRLF)
    Next
Else
    ConsoleWrite(@CRLF & "No Object" & @CRLF)
EndIf

Okay. But now I only need the value of .Size and not the collection of (in this case one) object(s) that is returned by the query. So my question: Is there a way to phrase a WMI query in WQL that only returns this value as an int or string or something?

Regards,

Chris
