ClassWizard derived-class message maps

     I have noticed that ClassWizard, when dealing with a class derived 
     more than one level deep from an MFC class, will not recognize the 
     type of class and will not give a complete choice of messages.  It 
     instead gives you nothing but the standard CWnd (WM_???) messages to 
     choose from.  This forces me to hand-write the macros for specific 
     messages like CBN_SELCHANGE, etc.  To make clear what I'm talking 
     about:
     
     class Combo1 : public CComboBox {...}; class Combo2 : public CCombo1 
     {...};
     
     When you open CW with Combo1, you get the full range of messages to 
     choose from, including CBN_???.  However, with Combo2, you don't.
     
     This is probably just a bug, but does anyone know any workaround?

One workaround that I believe will work is to derive the combo2 from
a standard CComboBox, then edit the source and change it to CCombo1.
There may be a more correct method, such as importing the CCombo1
class into the class wizard, but I haven't actually tried that.

Hello!

I had the same problem ,but I think I found the workaround...
Try to remove this class from ClassWizard and insert it again.Then do Update
All Dependencies.
It must work.

Regards!
