HOWTO: Enumerate Windows Management Instrumentation Namespaces

Q246204

The information in this article applies to:

Windows Management Instrumentation, versions 1.0, 1.1, 1.5

SUMMARY

You cannot enumerate all the Windows Management Instrumentation (WMI) namespaces on a computer by using a single query in a single namespace.

MORE INFORMATION

In order to enumerate all the namespaces, you must first connect to the "root" namespace, query for all the "__NAMESPACE" instances, and for each instance recursively repeat this process.

The following Microsoft Visual Basic code snippet is a recursive subroutine that enumerates the namespaces under the namespace tree rooted at the namespace specified in the parameter.

Sub PrintNamespaces(namespace As String)

Debug.Print namespace
Set locator = CreateObject("WbemScripting.SWbemLocator")
Set wmi = locator.ConnectServer(".", namespace)
For Each obj In wmi.InstancesOf("__NAMESPACE")
    PrintNamespaces namespace + "\" + obj.Name
Next

End Sub

To enumerate all of the namespaces on the computer, call the subroutine with "root" as the parameter:

PrintNamespaces "root"

Additional query words: wmi wbem namespace enumerate
