Duration of video file!

[christiant]

Hey
How do I get Visual Basic to find information about a video file, such as its duration? In Windows XP it is easy to find this information by choosing the options for the file - so it must be possible!

Thank you in anticipation!

Do you mean you want it through code?

I am not sure what you mean, but I am coding a program, where I need Visual Basic to know the duration of a video file, so that I can calculate with it!

Yes, this can be done.

Just a chunk from a large prog I did once

Set media_control = New FilgraphManager         'Filter controls and properties
    
    iFile = FreeFile
    Open App.Path + "\TempAVI.avi" For Binary As #iFile
        bArr = LoadResData(sMovieToPlay, "CUSTOM") 'change this to reflect the correct ID
        Put #iFile, , bArr
    Close #iFile
 
    media_control.RenderFile (App.Path + "\TempAVI.avi")
    Set media_window = media_control                'Payback window properties and controls
    Set media_position = media_control              'Playback position properties and controls

The play time is accessed something like

media_position.StopTime

Oh and you need to use the Quartz.dll

Hey I have tried to use the code above, but it wont work. Obvious I'm not that good at VB, so you have to make it very clear what I have to change in the code.

First of all I can't choose FilgraphManager. I have tried to use the name of my own project, but it "wasn't expected".

Next VB can't find identifier for sMoviePlay.

Hi,

Sorry, the chunk of code I posted is just a bit of my program.

The movies are stored in a resource file in my case and the movie identified by the string "sMovieToPlay" is shown being loaded into a temporary file.

You could just use

media_control.RenderFile (App.Path + "\TempAVI.avi")

to load your .avi

You need to set a referenve to the "Active Movie Control Type Library in the Project References.

Hope this helps a bit more.
At the moment project pressures don't allow me time to put together a working example.

If you're still stuck let me know and when I have a bit more time, I will post a full example.
