Hi Community,

i want to dispatch an Event from c#.


        public void fireEvent()
        {
            nsAString sEv = new nsAString("StreamEvent");
            nsAString name = new nsAString("PeterTest");
            nsAString data = new nsAString("VieleDaten");
            nsAString text = new nsAString("GuterText");

          nsIDOMStreamEvent streamEvent = Xpcom.QueryInterface<nsIDOMStreamEvent>(WebBrowser);
          streamEvent.initStreamEvent(sEv, true, false, name, data, text);
         
        }


Compiling works without error. But when i fireEvent()  the debugger tells me that my four nsAStrings are null objects and that i should use the new Operator, what i have actually done.

My Problem is that i dont know what i have to use for the queryinterface argument.

Xpcom.QueryInterface<nsIDOMStreamEvent>(WebBrowser);   ---> the WebBrowser is maybe not the correct argument.

Any ideas?

Thank you very much !
