ActiveCompanionSet xtras for Macromedia Director

Getting drive details with WMI

Windows Management Instrumentation (WMI) is a system level component that provides management information and control in an enterprise environment. Here is the sample that enumerates different properties of the logical drive C:

vb = xtra("VbScriptXtra")

-- Obtain WMI object for drive C:
devC = vb.GetObject2("WinMgmts:win32_LogicalDisk.DeviceId='C:'", "")

-- Getting the enumeration of available properties
props = ObjSet.Properties_.__NewEnum

-- Output available properties from a collection
repeat with i = 1 to props.count
  if props[i].value <> #Null then
    put props[i].name & ":" && props[i].value
  end if
end repeat

This sample outputs following information with my drive C:.
-- "Caption: C:"
-- "Compressed: 0"
-- "CreationClassName: Win32_LogicalDisk"
-- "Description: Local Fixed Disk"
-- "DeviceID: C:"
-- "DriveType: 3"
-- "FileSystem: FAT32"
-- "FreeSpace: 158916608"
-- "MaximumComponentLength: 255"
-- "MediaType: 12"
-- "Name: C:"
-- "Size: 4194902016"
-- "SupportsFileBasedCompression: 0"
-- "SystemCreationClassName: Win32_ComputerSystem"
-- "SystemName: EUGENE"
-- "VolumeName: SYS"
-- "VolumeSerialNumber: 77963952"

Getting process details with WMI

Here is the sample that enumerates different properties of the running Director.exe process:

vb = xtra("VbScriptXtra")

-- Obtain WMI object for executing query:
ObjSet = vb.GetObject2("WinMgmts:root\cimv2","")
ObjSet.debugMode = true

-- Create System helper object
sys = xtra("VbScriptXtra").CreateWrapper(#System)

-- Looking for Director.exe process
colItems = ObjSet.ExecQuery("Select * from Win32_Process " & \
                        "where ProcessId = " & sys.ProcessId & "" )

if colItems.Count = 0 then
  alert "Process not found"
  exit
end if

-- Getting enumerator object
colEnumerator = colItems.__NewEnum

-- The object of interest
objProcessInfo = colEnumerator[1]

-- Getting its properties collection
props = objProcessInfo.Properties_.__NewEnum

-- Output available properties from a collection
repeat with i = 1 to props.count
  if props[i].value <> #Null then
    put props[i].name & ":" && props[i].value
  end if
end repeat

This sample outputs following information with my instance of Director.exe.
