Hello,
I Create an activex named TMyForm,
anyone know how to reference to class TMyFormImpl instance?
I found a line of code "extern PACKAGE TMyForm *MyForm;" in file
MyFormImpl.h,
and I try to cast it to TMyFormImpl like this:
TMyFormImpl *pt = (TMyFormImpl *)MyForm;
the code is right, but pt point to 0 address.

Hello,
I am trying to access this instance from another class write myself.
Has it any global instance like "Application" in c++ builder
application?
Thanks for your response.

I wrote a class which hook the IE's activity, and fire an event wrote in
ActiveX myself.
To fire that event, I invoke member function Fire_OnDoSomething in the
instance of TXXXXImpl.
I've solved this problem now, with the help of setting a pointer "TXXXXImpl
*".
Thanks for your response.
