What is it you are trying to do? Instead of thinking about converting what you have provided, it might just be easier to figure out what you need to do in AutoIt then research the AutoIt code for it.

We did this the other day in another thread, to get a list of printers:

$strComputer = "."
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
$collPrinters = $objWMIService.ExecQuery("Select * FROM Win32_Printer")
For $printer In $collPrinters
    $name = $printer.name
    ConsoleWrite("Printer: " & $name & @CRLF)
Next

thanks very much for this.

I have used koda to design the form, and partially written a few code. for each printer, i need to get the list of all paper size supported. so for example i'll use your code to list all printers in a listbox, then on clicking any printer, another function will list all the paper size supported in another listbox

you used WMI,which is slow compared to API DLL calls in my code, and what if the system does not have it installed by default e.g winxp
