__event handler test: if (OnEventHandler) OnEventHandler(Myfunc);

[Guest]

I want to hook events handlers but need to test of any event handler is
assigned or not.

I need something like this:

__event void OnEventHandler(Myfunc)
....
if (OnEventHandler) OnEventHandler(Myfunc);
else DoMyFunction(Myfunc);
....

This "if (OnEventHandler)" does not get accepted by unmanaged C++ 2002.
Any tips how to test this?

In Delphi this was possible.

I do know that it is a list.
Maybe somthing like "if (OnEventHandler.Count>0)" could do the trick?

One (dirty) sollution is:

if (__eventHandlerList_MyNameSpace_CMyClass_OnEventHandler) OnEventHandler(Myfunc);
else DoMyFunction(Myfunc);

Anyone have a better sollution?
