Event and/or socket problems

[Jonas Bengtsson]

Hi all,

I'm trying to get to grips with sockets in wxwidgets. I have a few problems:

1) I don't get any events on incoming data or lost connection. I think 
I've set up everything as I should. The main thing that differs between 
my test application and the Socket sample seem to be that I don't have a 
wxWindow/wxFrame but instead create my own class that derives from 
wxEvtHandler. Perhaps I haven't set up the event handler correctly? Do I 
need to hook it up to something (besides the socket->SetEventHandler() 
call)?

2) My other problem is that if the server isn't running (i.e. I can't 
connect at the beginning) I can't connect when the server is started 
(I'm doing a while(!socket->WaitOnConnect(1)) loop).

Any ideas?

I've attached my test app, which should be self explanatory.

TIA,

Jonas
