The FileArchiveStats property retrieves an IWMEncFileArchiveStats object to determine the size of the archive file and the duration of the encoded content stored in the file.

Syntax

IWMEncFileArchiveStats = IWMEncStatistics.FileArchiveStats

Parameters

This property takes no parameters.

Property Value

An IWMEncFileArchiveStats object.

If this property fails, it returns an error number.

Number Description
0xC00D1B7D No statistics are currently available.
0xC00D1B7E The encoder engine is not currently archiving.

Remarks

This property is read-only. File size and duration information does not persist after the encoding process has stopped. You can create a timer object to retrieve the archiving statistics.

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 FileStats As IWMEncFileArchiveStats
  Dim lDuration As WMENC_LONGLONG
  Dim lSize As WMENC_LONGLONG

' Retrieve an IWMEncStatistics object and retrieve
' the IWMEncFileArchiveStats object from it.
  Set Stats = Encoder.Statistics
  Set FileStats = Stats.FileArchiveStats

' Find the duration (in seconds) and size (in KB) of the archive file.
  lDuration = FileStats.FileDuration * 10
  lSize = FileStats.FileSize * 10
