I have been using

ox = createobjectex("{1D836EC8-10AE-11D4-9A78-0050DAB55C7B}","")
ox.ResetPrinterDC(lcprinter,.hDC,2)

to call a dll that changes the duplex setting of the printer.

We finally upgraded to win2000 and and I am getting an error

OLE error code 0x80040154: Class not registered.

I would assume that is because the ID changed on the win2k machines.

Is there a way to get the class id? Or is there a better way to do this?

thanks in advance
