is DISPID_VALUE reliable for invokes on IDispatchs from scripts?
- by Georg Fritzsche
Continuing from this question, i am confused whether DISPID_VALUE on IDispatch::Invoke() for script functions and properties (JavaScript in my case) can be considered standard and reliable for invoking the actual function that is represented by the IDispatch?
If yes, is that mentioned anywhere in MSDN?
Please note that the question is about if that behaviour can be expected, not what some interfaces i can't know in advance might look like.
A simple use case would be:
// usage in JavaScript
myObject.attachEvent("TestEvent", function() { alert("rhubarb"); });
// handler in ActiveX, MyObject::attachEvent(), C++
incomingDispatch->Invoke(DISPID_VALUE, IID_NULL, LOCALE_SYSTEM_DEFAULT,
DISPATCH_METHOD, par, res, ex, err);
edit: tried to clarify the question.
