Hi,

We are not sure what you are trying to accomplish, but please note that the process started like that would be running on a server (because you are starting it from server code) while your browser user is possibly on the other side of the world.

The reason why it worked in dev mode and not in registered app, is because non-interactive web server is a Windows service process, which has no UI and can run when no user is logged in to the machine. That's the reason you can't start an interactive program from a code executed from within a service.

If you are creating an application where your server and client are always on the same PC, then you should use UWS Interactive Host - the one used in dev, and then you would be able to start an interactive application, like calculator or media player.

Please also see this thread.

Thanks for your reply.
We are having client-server architecture.There are two application one is Web application which one is to be hosted at the server and the other one Windows application is to be installed at the client system.

What i need is how i can invoke the windows application installed at client system through the web application(this is hosted at the server).

Hi,

This is more of a general programming question, rather than UWS-specific one, that you will have better chance answered competently at StackOverflow.com. You would need to start a process on the client, and doing so in the server application does not help at all. On the client, i.e. in the browser, a media file, like sound or video, can be played on the page.
