GetWindowLong return 0.

You need to call GetDlgCtrlID from outside the activex control as the 
function available within the control returns an arbitrary value of zero.

Take a look at this article

http://xendra.ens.uabc.mx/~sinfante/loo/libro/ch17_4.htm

particularly the paragraph preceeding the title "MFC and Ambient 
Properties". This really begs the question why you want the ID in the first 
place as activex controls have to be fully self containing to operate - with 
a few exceptions where sibling controls need to be able to locate each 
other.
