ActiveX and return class [message #444571]

I'm wondering how I would go about getting the object provided by a
listener to a OleControl object.

public void handleEvent (OleEvent event)
{
if (event.type == DOUBLE_CLK)
{
Variant args = event.arguments[0];
if (args == null) return;
/*What do i do?*/
}
}

How do I get the _OnAlertSelectedEvent e which is provided by this event?
And how would I get it's fields.

What does the type library info for the DOUBLE_CLK event for this particular
control look like?

I'm not sure what you mean by that. I don't have the source to the
activex control and the documentation is pretty sparse.
I figured out what the int for the event type by just adding event
listeners for events 0 - 1000, and 50 is the one that occurs when a user
double clicks.

In CPP or C# the event handler is a callback which is passed LPDISPATCH
(in the example called Alert).

HRESULT hr = Alert->QueryInterface( IID_IAlertData,(void**)&myalert);

IID_IAlertData is something imported from an ocx file and myalert is a
pointer to the proper class type (probably also imported from the ocx file.

You could try:

public void handleEvent (OleEvent event)
{
if (event.type == DOUBLE_CLK)
{
Variant arg1 = event.arguments[0];
if (arg1 == null) return;
if (arg1.getType() == OLE.VT_DISPATCH) {
OleAutomation auto = arg1.getAutomation();
... use the automation object to do whatever it is you
want to do, you need to find out what methods are available on it
auto.dispose();
}
arg1.dispose();
}
}
