How to get an added class to shwo up in class wizard

[nss]

In my old project I added a class CsortListCtrl derived from CListCtrl, and when I #included it (I think thats all I did) when I put a listctrl on the dialog and used the CW to make a variable for it, it gave me two choices for the type of the control: SO I could either make it CListCTrl or CSortListCtrl. In this new project I've put the control on the form, #included it, but the CW is only offering me one choice i.e. it can only be of type CListCtrl. WHat to do? I need

CSortLIstCTrl mySortCTrl;
