Hi,

      Can you give some details of what you are trying to achieve?

just consider the windows media player application, in that one i am able to open the mediaplayer and play the video.But i also need to operate the PAUSE & STOP buttons of media player through my labview button (like Normal Boolean Buttons) with out using Mediaplayer buttons.is there any chance for that one?

Hi nk0435,

It sounds like what you want to achieve is Inter-Application Communication; In other words, having a LabVIEW VI's Front Panel communicate with Windows Media Player and control the buttons.

You can acheive Inter-Application Communication using ActiveX. A brief article on this can be found here; You may also want to look at the Wikipedia article on ActiveX here.

With regard to communicating with Windows Media Player through LabVIEW, there is some very appropriate example code here.

I hope this helps,
