问题 According to sources here and here, this class should give me a nice and human-readable list of patches applied to Windows. What I want is a list of KB patches applied to a remote machine. ManagementScope scope; ConnectionOptions options = new ConnectionOptions(); options.Username = tbUsername.Text; options.Password = tbPassword.Password; options.Authority = String.Format("ntlmdomain:{0}", tbDomain.Text); scope = new ManagementScope(String.Format("\\\\{0}\\root\\cimv2", tbHost.Text), options)

问题 I try to connect remote computer by using winforms c#. My Code: private void Form1_Load(object sender, EventArgs e) { var connection = new ConnectionOptions(); connection.Username = "xx"; connection.Password = "xx"; var scope = new ManagementScope("\\\\111.111.111.22:6000\\root\\CIMV2", connection); scope.Connect(); // Exception occurs here.. } I get below Error in line scope.Connect(); Error: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in System

问题 I've created two functions in PowerShell, one that creates the Namespace ROOT\CustomCMClasses and one that creates the class Test . This piece works fine: Param ( $Namespace = 'CustomCMClasses', $Class = 'Test' ) Function New-WMINamespaceHC{ if (Get-WmiObject -Namespace 'root' -Class '__NAMESPACE' | Where-Object {$_.Name -eq $Namespace}) { Write-Verbose "WMI Namespace 'root\$Namespace' exists" } else { Write-Verbose "Create WMI namespace 'root\$Namespace'" $Ns = [WMICLASS]'root:__Namespace'

问题 Consider following code: using (ManagementEventWatcher watcher = new ManagementEventWatcher("select * from Win32_ProcessStopTrace")) { watcher.EventArrived += (object sender, EventArrivedEventArgs e) => { Console.WriteLine("{0} stopped", (string)e.NewEvent["ProcessName"]); }; watcher.Start(); while (!Console.KeyAvailable) System.Threading.Thread.Sleep(50); watcher.Stop(); } When I run this code (as admin), it notifies me as soon as I close any other application. First: When using Win32

问题 def getPnpDeviceInfo(): c = wmi.WMI() wql = "SELECT * FROM Win32_PnPEntity WHERE Manufacturer != 'Microsoft' AND NOT PNPDeviceID LIKE 'ROOT\\%'" print ("All physical PNP devices") for J in c.query(wql): print(J) This function (the query) typically returns all physical PNP devices, here is an output sample : instance of Win32_PnPEntity { Caption = "ACPI Lid"; ClassGuid = "{4d36e97d-e325-11ce-bfc1-08002be10318}"; ConfigManagerErrorCode = 0; ConfigManagerUserConfig = FALSE; CreationClassName =

问题 I was wondering if there was a simple way to use WMI to get you the current windows user name with domain. The Windows API call just gets you the short username, so you end up doing another call for the domain name. I have some code, but I get an automation error. Any ideas? I think I'm on the right path, but I am a little new to WMI. Function GetFullName() As String Dim computer As String computer = "." Dim objWMIService, colProcessList As Object Set objWMIService = GetObject("winmgmts:\\" &

问题 I'm Trying go GET CPU values using WMI classes but with no lucky. With the class Win32_PerfFormattedData_PerfOS_Processor , I'm always getting the same values they don't change... With the WMI class Win32_PerfRawData_PerfOS_Processor , the value of PercentProcessorTime is equal to PercentProcessorTime , something is wrong. #!/usr/bin/perl -w use strict; use warnings; use Win32::OLE; use Data::Dumper; my $class = "Win32_PerfFormattedData_PerfOS_Processor"; my $key = 'Name'; my @properties = qw

问题 I'm trying to use WMI to defrag my C: Drive. I'm running Windows 7 Pro x64. Console.WriteLine(SMARTManager.Instance.SMARTHDD.Defrag("C:", ref ERR)); Function: public string Defrag(string a_DriveName, ref string ERR) { try { ManagementObject classInstance = new ManagementObject("root\\CIMV2", String.Format("Win32_Volume.DeviceID='{0}'", a_DriveName), null); // Obtain in-parameters for the method ManagementBaseObject inParams = classInstance.GetMethodParameters("Defrag"); // Add the input

问题 How do I find out if the computer I'm on has daylight saving time in effect? (preferably using WMI) According to this article at TechNet, I could query SELECT DaylightInEffect FROM Win32_ComputerSystem , but the property DaylightInEffect is not supported on Vista or Win7. As my program will run on various systems (XP, Vista, 7), I would appreciate some portable way of finding out. 回答1: The documented supported OS list is not accurate, this works fine on Win7 when I try it. I can't think of

问题 I am trying to use this code on Windows 2000: foreach (Process p in Process.GetProcesses()) { if (p.MainModule.FileName.EndsWith("calc.exe")) { using (ManagementObjectSearcher mos = new ManagementObjectSearcher( "SELECT CommandLine,ExecutablePath FROM Win32_Process WHERE ProcessId=" + p.Id.ToString())) { using (ManagementObjectCollection moc = mos.Get()) { foreach (ManagementObject mo in moc) { MessageBox.Show((string)mo["CommandLine"]); return; } } } } } This works on Windows XP and higher,
