How to receive the drop files message?

[zhanglr]

Hi,

I want to write a ActiveX Control (with ATL) which is able to accept drop
files.

It works properly in Dialog base application. but When I try to use it in
html, it cannot receive the wm_dropfiles message. It looks like browser,IE,
will receive and handle the message at first (open the file in IE directly).

would you pls tell me what I can do to let my activeX control be able to
recieve the message ,wm_dropfiles, in IE?

Yours,
