Problem with ATL Sink class for catching another ATL's events
ok. I made the messages go away by declaring the _ATL_FUNC_INFO into the
cpp, so this way, it's not included each time another file include the .h. I
took it from the ATLEventHandling example from MSDN. maybe it can help you
too. ;)
thanks.
