ModemJunki Posted June 29, 2013 Share Posted June 29, 2013 I have what I hope is a simple noob programming question. In the code snippet below, I make an WMI query and store the results in $objItems. Then I run through $objItems with a For loop. If I try to re-use $objItems after I do this, the date stored in it isn't there. I have to re-run the WMI query to have valid data. Is that normal? Or should I query, store the data I need to variables, and then be able to reuse them? Example workflow: Query WMI, store to $objItems. Loop through and find there are no disks matching my variables that have partitions. After I have more functions to create partitions, but I have to re-query WMI to reuse the same $objItems array because all the objects are now null. $objItems = $objWMI.ExecQuery("SELECT * FROM CIM_DiskDrive", "WQL", 0x10 + 0X20); query WMI for disk information If IsObj($objItems) Then ; we check for existing partitions and clean them if needed, then reboot For $objItem In $objItems If $objItem.SCSIBus = $sSysDiskBus And $objItem.SCSIPort = $sSysDiskPrt And $objItem.InterfaceType = "SCSI" And $objItem.Partitions <> 0 Then _cleanDisk($objItem.Index); will reboot when it's done EndIf Next EndIf Always carry a towel.

JohnOne Posted June 29, 2013 Share Posted June 29, 2013 It might be going out of scope if your code is in a function.

water Posted June 29, 2013 Share Posted June 29, 2013 Please show us the complete script. Without the code I just can ask my crystal ball and guess. Important is the part where you define variable $objItems.

ModemJunki Posted July 3, 2013 Author Share Posted July 3, 2013 Hi, sorry for the delay! I have since eliminated the problem with some rewriting that doesn't try to reuse the query but, I think JohnOne was on the right track. I was making the query outside a function then trying to reuse it inside a function for the second use. Always carry a towel. Link to comment Share on other sites More sharing options...
