IWMSPublishingPoint.FileDescriptions (Visual Basic .NET)
The FileDescriptions property retrieves an IWMSFileDescriptions collection containing information about files, directories, and playlists in a specified publishing point path.
Syntax
IWMSFileDescriptions = IWMSPublishingPoint.FileDescriptions( strRelativePath As String )
Parameters
strRelativePath
[in] String containing a subdirectory or file in the base path. You can use the IWMSPublishingPoint.Path property to specify the base path.
Property Value
An IWMSFileDescriptions object. This is NULL if the publishing point path does not contain a directory, media file, or playlist file. You can use the IWMSPublishingPoint.Path property to retrieve the publishing point path.
If this property fails, it returns an error number.
| Number | Description |
| 0x00000002 | The file indicated by strRelativePath was not found. |
| 0x00000003 | The path indicated by strRelativePath was not found. |
| 0xC00D1580L | The data source plug-in that the server is attempting to use to access the path referenced by strRelativePath does not support enumeration of files. |
| 0xC00D145AL | The publishing point was already removed. |
| 0xC00D157EL | The server was not able to find a data source plug-in to access the path referenced by strRelativePath. |
| 0xC00D1452L | The method is not supported for cache proxy publishing points. |
Remarks
This property is read-only. If the publishing point path contains either a media file or playlist file, the IWMSFileDescriptions object will contain information about only that file, and an error is returned if any value other than a zero-length string is specified in the first parameter.
This method is not supported for cache proxy publishing points.
This method requires the Network Service account to have read and browse access to the specified path.
Example Code
Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices
Private Sub GetFileInfo()
' Declare variables.
Dim Server As WMSServer
Dim PubPoints As IWMSPublishingPoints
Dim PubPoint As IWMSPublishingPoint
Dim FileDescriptions As IWMSFileDescriptions
Dim strText As String
Try
' Create the WMSServer object.
Server = New WMSServer()
' Retrieve the IWMSPublishingPoints object.
PubPoints = Server.PublishingPoints
' Retrieve information about each publishing point.
For Each PubPoint In PubPoints
' Retrieve the IWMSFileDescriptions object
' containing information about files available to the
' publishing point.
strText = ".\\"
FileDescriptions = PubPoint.FileDescriptions(strText)
Next
