I have code that does a WMI SQL query to find all defined printers, and I want to parse the returned object in several places. However, after parsing it the first time, all other times fail to find any printer objects. Here is my test code: test() Func test() Local $oPrinters, $oPrinter, $err, $cnt, $oP, $query $query = "SELECT * FROM Win32_Printer" $oPrinters = doQuery($query) $err = @error LogMsg("+++: $err = " & $err & ", isObj($oPrinters) = " & IsObj($oPrinters)) If ($err == 0) Then LogMsg("FIRST LOOP") ; <=== FIRST LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") LogMsg("SECOND LOOP") ; <== SECOND LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") EndIf EndFunc ;==>test Func doQuery($sQuery, $lnum = @ScriptLineNumber) #forceref $lnum LogMsg("+++:" & $lnum & ": doQuery(" & '"' & $sQuery & '"' & ") entered") Local $oWMIService, $oResults, $errstr Local $wbemFlags = BitOR(0x20, 0x10) ; $wbemFlagReturnImmediately and wbemFlagForwardOnly $oWMIService = ObjGet("winmgmts:\\" & "localhost" & "\root\CIMV2") If (IsObj($oWMIService)) Then $oResults = $oWMIService.ExecQuery($sQuery, "WQL", $wbemFlags) If (IsObj($oResults)) Then LogMsg("+++: doQuery() returns @error = 0, Good: returning the object") Return (SetError(0, 0, $oResults)) ;;; Good: return the object Else $errstr = "" _ & "WMI Query failed." & @CRLF _ & "This is the query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") LogMsg("+++: doQuery() returns @error = 1") Return (SetError(1, 0, $errstr)) ; Error: Query faled EndIf Else $errstr = "" _ & "WMI Output" & @CRLF _ & "No WMI Objects Found for class: " & @CRLF _ & "Win32_PrinterDriver" & @CRLF _ & "using this query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") MsgBox(0, "ERROR", $errstr) ; Error: Cannot get $oWMIService object Exit (1) EndIf EndFunc ;==>doQuery Func LogMsg($msg, $lnum = @ScriptLineNumber) ConsoleWrite("+++:" & $lnum & ": " & $msg & @CRLF) EndFunc ;==>LogMsg Parsing the returned $oPrinters object shows 5 printers: +++:15: FIRST LOOP +++:18: +++: isObj($oP) = 1 +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Microsoft XPS Document Writer<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Microsoft Office Document Image Writer<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Fax<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Canon MG7100 series Printer WS<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Canon MG6100 series Printer WS<== +++:24: +++: Found 5 printers Parsing it again, shows no printers: +++:26: SECOND LOOP +++:29: +++: isObj($oP) = 1 +++:35: +++: Found 0 printers
