play cd audio labview

[mbaudot]

Bonjour,
J'ai trouvé sur le forum un VI permettant de lire les pistes d'un CD audio avec LabView et ça fonctionne très bien (merci à son auteur).
Cependant, j'aimerais aussi avoir comment récupérer des informations sur la lecture en cours, notamment la piste en cours de lecture, la durée restante, le temps en cours, le nombre de pistes du CD inséré. Je sais que que winmm.dll permet de récupérer ces informations, mais je ne sais pas comment coder ça en LabView.
Je joins le fichier original qui permet la lecture des pistes.
Merci d'avance pour votre aide.

Hello,
I've found on this forum au VI which can play audio CD tracks with LabView and it works great (thanks to the author).
But I would to know how to recover the playing track, the elapsed time, the playing time, and the number of tracks on the cd. I Know that winmm.dll permit this functions but I don't know how to code that with LabView.
I join the original Vi which plays the audio tracks.
Thanks for help.

Hi,

It's useless to post 2 topics on the French and English forum for the same problem.
Somebody answers here, advicing to have a look on the web to find this kind of page

You need to use a call library node, double-click the node and then enter the correct parameters to call the DLL winmm.dll properly.
Browsing documentation will help you to find the function that fit your needs.

I browsed the documentation of winmm.dll ant there's no description about the functions and no description about the parameters of the functions. So knows someone the function of the dll to call and his parameters to recover datas I enounce above ???
Tanks.
