Hallo Norbert,

ich habe leider vergessen zu sagen, dass ich LabWindow/CVI 6.0 verwende. Leider habe ich den Transfair nicht alleine geschafft, so dass es auch bei LabWindow/CVI 6.0 läuft. Wenn Du mir nochmals helfen könntest wäre das echt super danke.

Hello Paco,

Unfortunately I do not speak German, however I gather that you are using CVI 6.0 but could not get the button to work.  The Windows media player ActiveX control that is used allows events like the endofstream to be a registered event and will allow you a callback to handle that event.  In that event, you will want to call to an ActiveX method to change the state of the player.  I assume that when you reach the end of the stream you want a button to change to play so that when the user presses that button the video feed will start over.  To do this, use the IMediaPlayerPause / IMediaPlayerPlay / IMediaPlayerStop with manipulations of the marker times to set where you would like playback to begin.

Hope that helps, and let me know if I can help you with anything else.
