alternative to COM??

You might try CORBA: http://www.trolltech.com/products/so...ities/qtcorba/

@TheKedge,
Qt is a GUI toolkit, that with time grew to support additional stuff like a bit of network, and with Qt4 you can also write specifically console applications.
So I think your question has no meaning, in the sence, that using COM has nothing to do with basing your application on Qt or not.
If what you need is a crossplatform solution, then KORBA might be a solution, but its slower then native solutions.
If however you dont need a crossplatform solution, there is nothing to prevent you from using COM along a Qt based application.
Qt based applciation is nothing more then a C++ (if that is what you use) application that can use COM just like any other application.
