IWMEncStatistics.IndexerStats
.gif) |
The IndexerStats property retrieves an IWMEncIndexerStats object to determine the number of files being indexed, the name of a file in the queue, and the percentage of indexing completed on the current file.
Syntax
IWMEncIndexerStats = IWMEncStatistics.IndexerStats
Parameters
This property takes no parameters.
Property Value
An IWMEncIndexerStats object.
If this property fails, it returns an error number.
| Number | Description |
| 0xC00D1B7D | No statistics are currently available. |
Remarks
This property is read-only. The IWMEncIndexerStats object monitors the indexing process for a Windows Media file. A file index enables operations, such as fast forwarding, that must seek to specific time offsets in the file. If you specify an archive file, the indexing process starts automatically on a separate thread in the background of the encoding process immediately after the archiving process stops. The indexing process stops at the end of the file.
Example Code
' Create a WMEncoder object.
Dim Encoder As WMEncoder
Set Encoder = New WMEncoder
' Configure the encoding session including the sources, output,
' and profile, then start encoding.
' You can create a timer control to retrieve the statistics
' (as follows) after you start the encoding session.
' Declare objects and variables.
Dim Stats As IWMEncStatistics
Dim IndexStats As IWMEncIndexerStats
Dim lFileCount As Long
Dim sFileName As String
Dim lPercent As Long
' Retrieve an IWMEncStatistics object, and use it to
' retrieve an IWMEncIndexerStats object.
Set Stats = Encoder.Statistics
Set IndexStats = Stats.IndexerStats
' Retrieve the number of files remaining in the queue.
lFileCount = IndexStats.FileCount
' Retrieve the name of a specific file in the queue.
sFileName = IndexStats.FileName(0)
' Retrieve the percentage of indexing completed on the
' current file.
lPercent = IndexStats.PercentComplete
