<\/A> \nHey, KC. This is one of those questions we hate, not because we don\u2019t have an answer for it – we do – but because we have to temporarily abandon one of the core tenets of the Scripting Guy Way of Life. That tenet – just a second while we blow the dust off it- is this: ADSI should be used for managing Active Directory and other directory services (including local computer accounts); WMI should be used for everything else.<\/P>\n
Ok, so maybe it\u2019s not<\/I> the 10 Commandments or the Golden Rule. But hey, we\u2019re scripting <\/I>guys, not philosophy guys.<\/P>\n
Although ours is a simple way of life, most of the time this tenet works just fine. For example, suppose you\u2019re using Windows XP or Windows Server 2003 as a print server. Want to delete all the print jobs running on that computer? All you do is use a WMI script, just like we told you to:<\/P>
strComputer = “.”\nSet objWMIService = GetObject(“winmgmts:\\\\” & strComputer & “\\root\\cimv2”)<\/p>\nSet colInstalledPrinters = objWMIService.ExecQuery _\n (“Select * from Win32_Printer”)<\/p>\n
For Each objPrinter in colInstalledPrinters\n objPrinter.CancelAllJobs()\nNext\n<\/PRE>\n
But what if you\u2019re using a Windows 2000 computer as a print server? Well, in that case we have a problem: the CancelAllJobs()<\/B> method – used to delete print jobs from a printer on Windows XP and Windows Server 2003 – doesn\u2019t exist on Windows 2000. Not only that, but there\u2019s no comparable method to be found anywhere in the WMI repository. The cold, hard fact of the matter: you can\u2019t use WMI to delete all the print jobs on a Windows 2000 computer.<\/P>\n
Now, people of good moral fiber would simply stop at this point; after all, they would never compromise their principles just to delete a bunch of print jobs on a print server. We Scripting Guys have no such qualms, however; therefore, here\u2019s an ADSI script that can delete all the print jobs on a Windows 2000 computer:<\/P>
Set objComputer = GetObject(“WinNT:\/\/atl-ps-01”)\nobjComputer.Filter = Array(“printQueue”)<\/p>\nFor Each objPrinter in objComputer\n objPrinter.Purge \nNext\n<\/PRE>\n
As you can see, we begin by using the WinNT provider to connect to the print server atl-ps-01. (By the way, WinNT<\/B> is case-sensitive; your script will fail if you try using winnt or WINNT or any other variation.) This returns a collection of all the \u201cthings\u201d on atl-ps-01, or at least all the things ADSI knows about: user accounts, groups, services, and – hey! – printers. Because we only care about the printers we apply a Filter<\/B> that limits the returned data to printQueue<\/B> objects; as you might expect, printQueue is the ADSI designation for a printer object. The filter requires just one line of code:<\/P>objComputer.Filter = Array(“printQueue”)\n<\/PRE>\nIncidentally, the object we\u2019re filtering on – printQueue – must be configured as an array. This code looks<\/I> like it should work, but it won\u2019t:<\/P>objComputer.Filter = “printQueue”\n<\/PRE>\nAll that\u2019s left now is to loop through the collection of printers and – for each printer found – delete all the print jobs, something we can do using the Purge<\/B> command. Deleting all the print jobs on all the printers takes just three lines of code:<\/P>For Each objPrinter In objComputer\n objPrinter.Purge \nNext\n<\/PRE>\nNot too bad, huh? If you\u2019d like more information about managing print servers on Windows 2000 you might check out the Printing chapter<\/B><\/A> in the Microsoft Windows 2000 Scripting Guide. And if you\u2019d like more information about breaking the rules, just keep reading this column; we\u2019re bound to break a few more before we\u2019re through.<\/P><\/p>\n","protected":false},"excerpt":{"rendered":"Hey, Scripting Guy!
