Windows Media Player

I'd like to be able to launch Media Player on a different machine to play
movies (this is a personal, rather than professional, need) whilst retaining
control on the local machine. DCOM should be able to do this and Labview
should be able to drive it; however I can't figure out how. The "GAMP"
example shows how to use MediaPlayer to play files when MP is embedded in an
ActiveX control on the front panel, but I can't figure out how to open MP's
window independently and issue commands to it. I don't really want to have
Labview loaded on the remote machine just for a container!

Can anyone tell me how to get the window open?

Craig,
I believe your question is best answered by the following KB and the devzone article it links to.

Hi Craig,

I did not manage to handle remote ActiveX on the remote machine.
An idea is to develop a client application that runs the MP activeX on the client PC, then you have to develop a server application on your local PC that controls the client.
If you have the application builder you can create an .exe of the client application, so you need only the LV runtime on the remote machine.

Good luck and Merry Christmas!

This is an option, although I'll have a try myself at doing it directly
first; as I understand it, if the permissions are correct then you can
access ActiveX objects via DCOM on a remote machine without having to run
Labview on that remote machine.

The main problem though remains that I cannot open MP from Labview and
control it. The response from Amaury missed this point. I don't want to have
to run MP within a container in a Labview panel, I want to run it in its own
window. I could do it from Labview, but then I have the additional
complication of making all the sizes dynamically change to give me full
screen playback in either of 640x480 or 800x600 depending on the settings at
the time.

I have a suspicion, reinforced by the lack of responses here,
that the MP
executable is a stand alone application that just acts as a container to an
instance of the MP ActiveX object, and can't in itself accept external
commands. If so then there's little I can do but write a wrapper
application, either in Labview or C++, to reproduce the housekeeping
functionality. Unless someone knows of a way of opening the MP executable
and then getting a reference to the instance of the MP object it contains.
