I am using IWMSyncReader to iterate through a file and copy it. I was
wondering if anybody knew how to get a total sample from a Windows Media
file without parsing the ASF file itself (I would like to set up a progress
dialog box)

TIA

Jason,

While the SDK doesn't expose a "frame count", you could probably implement a
progress bar by comparing timestamps to the duration of the file. The
duration is available by querying the attribute g_wszWMDuration.
