Thanks Kevin. I have no particular problem. I just wanted to know. I just started reading about it, and I presume, that using dcop I can send request to an application, but where can I find what kind of commands application is able to serve? Is it in the documentation of an application? Or do I have to figure it out by reading source? ___________________________________________________ .
