How to determine time value of a .wav file in real time as it plays?

[F_Simon]

Hi all.
I need to build a vi in which a .wav sound file is represented in a Waveform graph, and at the same time, I want to play that file, and have a vertical cursor line running along the Waveform graph, in order to have a visual representation of where the sound track is, in terms of time.
Making the .wav file to appear graphicaly on a Waveform graph was an easy task to do, but then, I was´nt able to extract the time information of that .wav file, at the same time that this file is being played.
This is a very common situation in music players, video players etc, where some kind of graphical artifact, represents in real time where the track is while it plays.

Hi, this is the first ActiveX control I have played with but its really cool.

I read this first: -
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmplay10/mmp_sdk/iwmpcontrolsinterface.asp
Which covers "The IWMPControls interface provides a way to manipulate the playback of a media item."

Then built the attached sample.
It should now be straight forward to attach the position information shown to a graph control cursor postion.
You will need to set a file of your own choosing in the VI first.

Let us all know if this is what you wanted.

Hi.
Yes, this is it.
Thank you very much buddy.
And by the way:
Where can I get more Activex files?

Cheers

I am sure you can download them but most will come as part of Windows or other components that you install on your system. You can of course write your own.....
