exec method WMI

[future_retro]

Hi, I'm trying to use the AddPrinterDriver method of
Win32_PrinterDriver to create a new..... print driver. I can't get my
head round how I need to do this. So far I have

import win32com.client
WBEM =
win32com.client.GetObject(r"winmgmts:{impersonatio nLevel=impersonate}!\\"
+ "." + r"\root\cimv2")
WBEM.Security_.Privileges.AddAsString("SeLoadDrive rPrivilege")
drv = WBEM.Get("Win32_PrinterDriver").SpawnInstance_()
drv.Properties_('Name').Value = "Marcs Printer 2550"
drv.Properties_('SupportedPlatform').Value = "Windows NT x86"
drv.Properties_('Version').Value = "3"
drv.Properties_('DriverPath').Value = 'C:\\test\\HPZPP034.DLL'
drv.Properties_('InfName').Value = 'C:\\test\\hpc2550d.inf'
method = drv.Methods_('AddPrinterDriver')
InParms = method.InParameters
InParms.Properties_.Item('DriverInfo').Value = drv
drv.ExecMethod_('AddPrinterDriver',InParms)

I'm using spawninstance to create a new object and then editing the
properties of it. I'm then setting the InParameters for the method to
be the new object. When executing the method I get SWbemObjectEx
object not found.

I think I am not setting the DriverInfo correctly, should it be an
object? The MSDN site doesn't say what DriverInfo should be.

Any help would be grand.

Thanks, MW.

You probably need to remove the SpawnInstance_() call.
An abstract WMI class as returned by WBEM.Get should work
for the DriverInfo parm, since the concrete Win32_PrinterDriver
instance is what the AddPrinterDriver call is trying to create.

Got it working, removed spawninstance and the driver path should have
been "C:\\test\\"

Cheers for your help Roger.
