        // bind it to a 'real' manageable entity
        o.Path =

        Console.WriteLine(o.Qualifiers["Description"].Value);

        return 0;
    }
}

Imports System.Management

Class Sample_ManagementClass
    Public Overloads Shared Function Main( _
        ByVal args() As String) As Integer

        Dim s As New ManagementScope( _
            "\\MyMachine\root\cimv2")
        Dim p As New ManagementPath( _
            "Win32_Service")

        ' Set options for no context info,
        ' but requests amended qualifiers 
        ' to be contained in the object
        Dim opt As ObjectGetOptions
        opt = New ObjectGetOptions( _
                Nothing, TimeSpan.MaxValue, True)

        Dim o As ManagementObject
        o = New ManagementObject(s, p, opt)

        Console.WriteLine(o.Qualifiers("Description").Value)

        Return 0
    End Function
End Class

Remarks

Because WMI paths can be relative or full, a conflict between the scope and the path specified may arise. However, if a scope is specified and a relative WMI path is specified, then there is no conflict. The following are some possible conflicts:

If a scope is not specified and a relative WMI path is specified, then the scope will default to the local machine's DefaultPath.

If a scope is not specified and a full WMI path is specified, then the scope will be inferred from the scope portion of the full path. For example, the full WMI path: \\MyMachine\root\MyNamespace:MyClass.Name='abc' will represent the WMI object 'MyClass.Name='abc'" in the scope '\\MyMachine\root\MyNamespace'.

If a scope is specified and a full WMI path is specified, then the scope will override the scope portion of the full path. For example, if the following scope was specified: \\MyMachine\root\MyScope, and the following full path was specified: \\MyMachine\root\MyNamespace:MyClass.Name='abc', then look for the following object: \\MyMachine\root\MyScope:MyClass.Name= 'abc' (the scope part of the full path is ignored).
