IWMSFileDescriptions.length (Visual Basic .NET)

The length property retrieves the number of file description objects contained in the collection.

Syntax

  Integer = IWMSFileDescriptions.length

Property Value

Integer containing the number of file description objects contained in the collection.

Remarks

If the publishing point path references a playlist, the length property returns 1. It does not retrieve the number of media files referenced by the playlist.

This is the JScript version of the Count property. It is included for developers who are more comfortable with JScript syntax.

This property is read-only.

Example Code

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

Private Sub GetCount()

    ' Declare variables.
    Dim Server As WMSServer
    Dim FileDescriptions As IWMSFileDescriptions
    Dim strPath As String
    Dim iCount As Integer

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

    ' Retrieve the IWMSFileDescriptions object.
    strPath = "file://c:\wmpub\wmroot"
    FileDescriptions = Server.FileDescriptions(strPath, WMS_FILE_TYPE.WMS_FILE_UNSPECIFIED)

    ' Retrieve the total count of descriptions.
    iCount = FileDescriptions.length

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
