The IWMSNamedValues object contains a collection of name-value pairs.

The IWMSNamedValues object exposes the following properties.

Property Description

Count Retrieves the number of name-value pairs contained in the IWMSNamedValues collection.
Item Specifies and retrieves a name-value pair from the IWMSNamedValues collection.
length Retrieves the number of name-value pairs contained in the IWMSNamedValues collection. This method is provided for JScript compatibility.
Remove Removes a name-value pair from the IWMSNamedValues collection.

Example Code

The following example illustrates how to retrieve an IWMSNamedValues object.

Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices

Private Sub RetrieveObj()

    ' Declare variables.
    Dim Server As WMSServer
    Dim NamedValues As IWMSNamedValues
    Dim NamedValue As IWMSNamedValue

Try
    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Retrieve the IWMSNamedValues object containing
    ' descriptive information about the server.
    NamedValues = Server.Properties

Catch excCom As COMException
    ' TODO: Handle COM exceptions.
Catch exc As Exception
    ' TODO: Handle errors.
Finally
    ' TODO: Clean-up code goes here.
End Try

End Sub

System and custom plug-ins contain default name-value pairs that can be accessed by simply indexing the name of the property you want to retrieve. For a list of the default values you can access, see Registering Plug-in Properties.

The following example illustrates how to retrieve some default configuration values from the WMS Digest Authentication plug-in.

Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices

Private Sub GetConfigValues()

    ' Declare variables.
    Dim Server As WMSServer
    Dim Plugins As IWMSPlugins
    Dim Plugin As IWMSPlugin
    Dim Properties As IWMSNamedValues
    Dim WMSSystemPlugin As Integer
    Dim MMCMoniker As String
    Dim ASPMoniker As String
    Dim UnsupportedLoadTypes As Integer
    Dim Realm As String
    Dim Name As String
    Dim Description As String
    Dim Author As String
    Dim Copyright As String

Try

    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Retrieve the WMS Digest Authentication plug-in.
    Plugins = Server.Authenticators
    Plugin = Plugins.Item("WMS Digest Authentication")

    ' Retrieve the configuration properties specified
    ' for the plug-in.
    Properties = Plugin.Properties
    WMSSystemPlugin = Properties.Item("WMSSystemPlugin").Value
    MMCMoniker = Properties.Item("MMCMoniker").Value
    ASPMoniker = Properties.Item("ASPMoniker").Value
    UnsupportedLoadTypes = Properties.Item("UnsupportedLoadTypes").Value
    Realm = Properties.Item("Realm").Value
    Name = Properties.Item("Name").Value
    Description = Properties.Item("Description").Value
    Author = Properties.Item("Author").Value
    Copyright = Properties.Item("Copyright").Value

Catch excCom As COMException
    ' TODO: Handle COM exceptions.
Catch exc As Exception
    ' TODO: Handle errors.

Finally
    ' TODO: Clean-up code goes here.

End Try

End Sub
