I've been working on a project that accesses the WMI to get information about the software installed on a user's machine. We've been querying Win32_Product only to find that it doesn't exist in 64-bit versions of Windows because it's an "optional component". I know there are a lot of really good alternatives to querying the WMI for this ...
Hey everyone, Is there any known way of listing the WMI classes and their properties available for a particular system? Im interested in a vbscript approach, but please suggest anything really :) P.S. Great site. ...
Hi everyone, and to the makers of the site - thanks. looks like a promising beta. I am trying to register to a "Device added/ Device removed" event using WMI.

I'm trying to be better about unit testing my code, but right now I'm writing a lot of code that deals with remote systems. SNMP, WMI, that sort of thing. With most classes I can mock up objects to test them, but how do you deal with unit testing a real system? For example, if my class goes out and gets the Win32_LogicalDisk object fo...

Hi - I've having trouble directly accessing the Win32_OperatingSystem management class that is exposed via WMI. It is a singleton class, and I'm pretty certain "Win32_OperatingSystem=@" is the correct path syntax to get the instance of a singleton. The call to InvokeMethod produces the exception listed at the bottom of the question, as...
I'm trying to check, using an automated discovery tool, when JAR files in remote J2EE application servers have changed content. Currently, the system downloads the whole JAR using WMI to checksum it locally, which is slow for large JARs. For UNIXy servers (and Windows servers with Cygwin), I can just log in over SSH and run md5sum foo.j...
I'm trying to verify when the OAB (Offline Address Book) root folder for a new OAB is created with powershell. Is there a WMI class that exposes this? I'm using powershell, but any examples or links will do. ...
I'd like to be able to see Win32_PhysicalMedia information when logged in as a Limited User in XP (not admin rights). It works ok when logged in as Admin, WMIDiag has just given a clean bill of health, and Win32_DiskDrive class produces information correctly, but Win32_PhysicalMedia produces a count of 0 for this code set WMI = GetObjec...

Does anyone have any idea how to track the signal strength of a bluetooth connection perferably in C#? I was thinking using a WMI query but couldn't track down the WMI class encapsulating the connection.

What is equivalent to the root\CIMV2\Applications\MicrosoftIE namespace on Vista/Server 2008? The root\cimv2\Applications\MicrosoftIE namespace dates back to at least Internet Explorer 5.00.2920.0000, which happens to be the version of Internet Explorer that shipped with Windows 2000, but it looks like it is removed from Vista/Server 20...
I need to write a function that generates an id that is unique for a given machine running a Windows OS. Currently, I'm using WMI to query various hardware parameters and concatenate them together and hash them to derive the unique id. My question is, what are the suggested parameters I should use? Currently, I'm using a combination of...
I need to create a PRIVATE message queue on a remote machine and I have resolved to fact that I can't do this with the .NET Framework in a straight forward manner. I can create a public message queue on a remote machine, but not a PRIVATE one. I can create a message queue (public or private) locally. I am wondering if anyone knows how ...

I have a setup executable that I need to install. When I run it, it launches a msi to do the actual install and then dies immediately. The side effect of this is it will return control back to any console you call it from before the install finishes. Depending on what machine I run it on, it can take from three to ten minutes so having t...
I use this code in my Windows Service to be notified of USB disk drives being inserted and removed: WqlEventQuery query = new WqlEventQuery("__InstanceOperationEvent", "TargetInstance ISA 'Win32_LogicalDisk' AND TargetInstance.DriveType=2"); query.WithinInterval = TimeSpan.FromSeconds(1); _deviceWatcher = new ManagementEventWatcher...
So I have made a webservice that interfaces with a set of data contained in a WMI namespace. It works fine when I run it with the ASP.net in built development web server, and returns the data as requested. However when I publish it to an IIS 6 server (win 2003), the webservice no longer allows me to execute the WMI method calls. However ...

Hello - I am creating a decoupled WMI provider in a class library.
