Re: python create WMI instances
I've got as far as this. I don't get any errors but still no
printer
import win32com.client
WBEM =
win32com.client.GetObject(rwinmgmts:{impersonationLevel=impersonate}!\\ +
. + r\root\cimv2)
printer = WBEM.Get(Win32_Printer).SpawnInstance_()
printer.Properties_('DeviceID').Value = 'myprinter'
printer.Properties_('DriverName').Value = 'HP 2000C'
printer.Properties_('Location').Value = 'myoffice'
printer.Properties_('Network').Value = 'True'
printer.Properties_('Shared').Value = 'True'
printer.Properties_('ShareName').Value = 'myprintershare'
printer.Put_
Do I need to specify any flags with Put_ ?
Thanks for all your help, I can almost taste victory!
MW.

I'm sorry my module won't have been much use to you
in this, but it would be *really* helpful if you
could post [a fragment of] the code you come up with
so I can see what changes I need to make to help our
future instance-spawners. It's just that I've never
had the need to do this, and don't have any time to
experiment at present.
Thanks

Well you certainly need to call it -- printer.Put_ () --
and not just refer to it. But maybe that's just a cut-and-paste
problem. In theory (according to the docs) you could pass a
CREATE_ONLY flag (or something like that) but I don't think
it's strictly necessary. I'd imagine that it would create if
it didn't exist. Check out msdn for more details than you
want to know.

Re: python create WMI instances
Right I got it working. I had to put a printer port in aswell. I'll
now look at a script to create printer ports. My goal is being able to
query the printers on print server x and then recreate the printers
(shares and ports) on print server y.
Thanks, for all your help Tim, much appreciated. MW

Re: python create WMI instances
Create isn't a method of Win32_Printer so I couldn't get that to work. .Create is a method of Win32_Process which (wait for it..) creates a new process. Unfortunatly there is no method to add a printer. the method .AddPrinterConnection will allow me to add a connection to an existing print share but I want to create a printer with the option of sharing it. I think I'll have to do this with spawninstance. Tim Golden wrote: [Marc Wyburn] | | Hi all, I am struggling with a vb - python code conversion.

As far as I understand you, the fact that you're creating on a remote machine is just an incidental, ie you'd have the same problem doing this locally.
