Graphics

Hello all,

I'm currently developing a little service to control the XPression.
However it is important that the XPression remains available for the user.

Right now, when I try to initialize the xpEngine, the software will launch XPression if it's not already running. But when that happens, the GUI is not available to the user.

How can I test if the Xpression is running and only then initialize my connection to the XPression?

Thank you,
Kenneth

Hey Kenneth,


try xpEngine.Showgui(true)



#XPression

Thanks for your reply @bderry, but what if I only want the user to decide whether or not XPression should be running. Maybe the user is closing XPression because he wants to shutdown the PC and I don't want my application to start XPression again...

Someone else will correct me if i'm wrong but, I believe whenever the xpEngine object is referenced the COM API launches XPression. You could try checking if your engine object is null but, I couldn't say myself without testing first.

You are correct @bderry, whenever the xpEngine is initialised, it will launch XPression, which is what I'm trying to prevent. Currently I'm checking if the XPression process is running before I start the XPression. But when I launch XPression manually, the application takes over and limits the view of the XPression.

This is indeed something I could solve with the ShowGUI but I washoping there was some cleaner way.

Also if XPression crashes, I don't really have any way of telling that it did...

if you want to check in the process is running you can use this method Process.GetProcessByName("XPression")
