ClassWizard VirtualFilter Options

I came across a problem with the VC++ ClassWizard a while ago. If you have a class derived from a standard MFC class, ClassWizard will offer to insert handlers for virtual function overrides. For example, for a class derived from CPropertyPage, you can add handlers for OnWizardNext, OnWizardFinish and so on. However, if you derive again, e.g.
CPropertyPage
CWizardPage
CWizPage1

Then ClassWizard will show virtual functions for CWizardPage but not for CWizPage1.

I discovered that this can be fixed by editing the ClassWizard *.CLW file and adding the 'VirtualFilter' option to the appropriate section. For example:

[CLS:WizPage1]
Type=0
BaseClass=WizardPage
HeaderFile=WizPage1.h
ImplementationFile=WizPage1.cpp
Filter=N
LastObject=WizPage1
VirtualFilter=idWC

The right hand side of VirtualFilter is a list of case-sensitive letters specifying which sets of virtual functions will be listed by ClassWizard. So, in the above example, ClassWizard will list virtual functions from CPropertyPage, CDialog, CWnd and CCmdTarget.

Here's the full list:

a CDatabase
b CListBox
c CComboBox
d CDialog
e -
f CFrameWnd
g COleMessageFilter
h CDialog
i CPropertyPage
j -
k CHttpServer
