ClassWizard Generated CToolBarCtrl::Create()

I wanted to add a toolbar control to one of my views, so I created my 
own class derived from CToolBarCtrl, added a member variable of this 
type to my view class and invoked CMyTBCtrl::Create() from within 
CMyView::OnInitialUpdate().  Everything works fine.

Next I decided to add some custom controls to my toolbar control and 
decided that I needed to create these custom controls when my toolbar 
control was created.  So I invoked ClassWizard, selected CMyTBCtrl 
and saw right there at the top of the "Messages" list; "Create".

(I later figured out that I wanted to override the OnCreate() method 
for my toolbar control, *not* the Create() method.)

However, when I double-clicked on "Create" the clicked on the "Edit 
Code" button I saw that ClassWizard had generated the following 
method declaration for me:

virtual BOOL Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName,
 DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID,
 CCreateContext* pContext = NULL);

This is the same method declaration for CWnd::Create(), not 
CToolBarCtrl::Create().  Indeed, when I rebuilt my application I got 
a compiler error in CMyView.cpp because my original invocation of 
CMyToolBar::Create() now had an incorrect number (and types) of 
parameters.

What I expected ClassWizard to generate was a method like the 
following:

virtual BOOL Create(DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID);

So, is this expected behavior?  Should ClassWizard have generated a 
CToolBarCtrl-style Create() method for me?

  ClassWizard similarly provides an (invalid) override of 
CWnd::Create() for CDialog-derived objects (which want to override 
CDialog::Create(), with its own different parameter list).

I had some problems like this what I did was to use the class CToolBar and 
not use CToolBarCtrl.
I just edited the cpp and h files to this.  This is much simpler to call, 
but there may be some functionality
in CToolBarCtrl that I will not be able to access but since my need was 
simple this works great.

Thanks.

It sounds like you've found a bug in ClassWizard.  I'll see if I can get it in 
front of one of the Wizards guys.
