问题 Looking into possibility of making an USB distributed application that will autostart on insertion of an USB stick and shutdown when removing the stick Will use .Net and C#. Looking for suggestion how to approach this using C#? Update: Two possible solutions implementing this as a service. - override WndProc or - using WMI query with ManagementEventWatcher 回答1: You can use WMI, it is easy and it works a lot better than WndProc solution with services. Here is a simple example: using System

问题 Can anyone point me to a vbscript (using WMI) to find out the installed SQL Server version. I have a scenario where either SQL Server 2008 R2 or SQL Server 2012 could be installed on a machine. 回答1: Based on the code in the first Google search result here: Dim WMI, Col, Prod, Q Set WMI = GetObject("WinMgmts:") Q = "Select * FROM Win32_Product WHERE Vendor = " & _ "'Microsoft Corporation' AND Name LIKE 'SQL Server%Database Engine Services'" Set Col = WMI.ExecQuery(Q) For Each Prod in Col if

I found a code that enables System Restore monitoring, but it's for C# and I need to convert it to Delphi. Here's the code: ManagementScope scope = new

问题 I am fairly new to the .NET programming and I am currently developing a computer health monitoring system which is in its infant stage now. I will be using C# 2010 and querying computer information by using WMI queries. Before I could further develop the application, I have created a mini test app to test out my classes and its methods. The flow of the test app is as follow: App startup Input hostname, username and password Query button clicked and the querying methods fired. A textfield on

问题 I noticed that ManagementObject is IDisposable , but it's also returned from ManagementClass.GetInstances() and ManagementObjectSearcher.Get() , does this mean I need to dispose each object encountered? Like so: ManagementObject ret; foreach(ManagementObject mo in searcher.Get()) { if( IsWhatIWant(mo) ) ret = mo; else mo.Dispose(); } Further confounding this: there's a bug in ManagementBaseObject where it does not correctly implement IDisposable (See Using clause fails to call Dispose? ) so

问题 I have configured the IP address for a NIC successfully in Windows7. But after pulling out the net cable, I can't get the IP address from API and ipconfig, but I can view it in "Network Connections". And if I insert the cable again, then I can get the address once more. How could I get or change the IP address of a NIC, when the NIC is disconnected? I have used "GetAdaptersInfo" "GetIpAddrTable" or WMI class. All above method return 0.0.0.0 ipaddress for such NIC. My platform is Windows7, and

问题 Is there a way to query via WMI in C# like you can do with the System.Diagnostics.PerformanceCounter class? Simply put how can I pass it a string like \\localhost\Processor(0)\% Processor Time and it would build the correct WMI query for me? I have huge list of counters in a flat file from a legacy program and I want to move it to a Service which just runs through the flat file and gets the value. 回答1: You can use the WMI Performance Class Counters. An example of this would be polling the

问题 The Win32_PerfFormattedData_* and Win32_PerfRawData_* classes are missing from my system. I'm running Windows 7, 64-bit, and using WMICodeCreator to browse the available classes. Neither WMICodeCreator nor my C# code can get information from them, and I have not been able to find any discussion boards talking about this particular issue. All other WMI classes are working perfectly fine. Could it be a service that I haven't started? 回答1: Start the perfmon to see if counters are present. If you

问题 I have to write a code to access hidden disk partitions/volumes using c# or c++. But could not find any help reference on the matter. As a hidden volume, it does not contain a "Disk Letter", so you can´t just type "C:\" and access it. A example would be the "recovery partition" that comes with Windows. You can´t see it on explorer but it is there. My application will write and read data from thoose partitions and I have to find a way of doing something like "c:\" for thoose. In the above

问题 i'm stoppinga service on remote machine with WMI: protected override void Execute() { ConnectionOptions connectoptions = new ConnectionOptions(); connectoptions.Username = RemoteMachineUsername; connectoptions.Password = RemoteMachinePassword; ManagementScope scope = new ManagementScope(@"\\" + RemoteMachineName + @"\root\cimv2"); scope.Options = connectoptions; SelectQuery query = new SelectQuery("select * from Win32_Service where name = '" + ServiceName + "'"); using
