Access the WMI Provider programmatically
WMI Provider overview
The namespace used to obtain information about Reporting Services in the code samples shown in this article is the System.Management namespace, found in the Microsoft .NET Framework. The System.Management namespace provides a set of managed code classes through which .NET Framework applications can access and manipulate management information. For more information on using the Reporting Services WMI classes with the System.Management namespace, see "Access Management Information with System.Management" in the Microsoft .NET Framework SDK.
Find a report server instance
The preferred way of finding information on your report server installations is to enumerate through the WMI instance collection. The following example shows how to find properties on every report server instance by creating a collection, and looping through the collection to display the properties.
Imports System
Imports System.Management
Imports System.IO
Module Module1
Sub Main()
Const WmiNamespace As String = "\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v10\Admin"
Const WmiRSClass As String = _
"\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v13\admin:MSReportServer_ConfigurationSetting"
Dim serverClass As ManagementClass
Dim scope As ManagementScope
scope = New ManagementScope(WmiNamespace)
'Connect to the Reporting Services namespace.
scope.Connect()
'Create the server class.
serverClass = New ManagementClass(WmiRSClass)
'Connect to the management object.
serverClass.Get()
If serverClass Is Nothing Then Throw New Exception("No class found")
'Loop through the instances of the server class.
Dim instances As ManagementObjectCollection = serverClass.GetInstances()
Dim instance As ManagementObject
For Each instance In instances
Console.Out.WriteLine("Instance Detected")
Dim instProps As PropertyDataCollection = instance.Properties
Dim prop As PropertyData
For Each prop In instProps
Dim name As String = prop.Name
Dim val As Object = prop.Value
Console.Out.Write("Property Name: " + name)
If val Is Nothing Then
Console.Out.WriteLine(" Value: <null>")
Else
Console.Out.WriteLine(" Value: " + val.ToString())
End If
Next
Next
Console.WriteLine("--- Press any key ---")
Console.ReadKey()
End Sub
