Using a VCL component outside a form ...

Hello
I use a TNMHTTP component on a form, it works fine

But now I want to use it inside a class. This component is
no more dropped on a form.
Declaration works fine :
TNMHTTP *NMHTTP1 = new TNMHTTP(0);

But I don't know how to trap the event messages ....

Thans for help
Adam

How to set event handlers at runtime:
http://www.bcbdev.com/faqs/faq1.htm
I notice that in BCB3, all of the Help for TNMHTTP is really Delphi
help. If you want to see the CPB code for the events, pretend you're
going to use a "dropped on form" component and double-click on the
events in the Object Inspector to see the C++ code. After copying the
function declarations, delete the visual component.

The article here basically illustrates how to work with closures at runtime. In fact, one thing I've done from time to time is to assign NULL to a closure (e.g. when I'm updating the control and don't want the closure to fire) then reassign the original handler when I'm done updating the control.
