How do you use a custom derived CXTPToolBar class and still keep toolbar customization?

Problem:
Getting an �An unsupported operation was attempted� error when the SaveCommandBars method is executed.

References:
Online Help � use index for �SetToolBarClass�
Online Help � use index for �cxtpcommandbars� (look at Add method)
Forum - http://forum.codejock.com/forum_posts.asp?TID=1932&K W=SetToolBarClass

Demonstration:
To see the error, use the �Notifications� sample in ��\Samples\CommandBars\Notifications�. Use a custom Toolbar:
1) Create a new toolbar class



class CXTPToolBarEx : public CXTPToolBar  

{

public:

    DECLARE_DYNCREATE(CXTPToolBarEx)





    CXTPToolBarEx();

    virtual ~CXTPToolBarEx();



protected:

    //{{AFX_MSG(CXTPToolBarEx)

        // NOTE - the ClassWizard will add and remove member functions here.

        //    DO NOT EDIT what you see in these blocks of generated code !

    //}}AFX_MSG

    DECLARE_MESSAGE_MAP()

};

2) Define it:



IMPLEMENT_DYNCREATE(CXTPToolBarEx, CXTPToolBar)



BEGIN_MESSAGE_MAP(CXTPToolBarEx, CXTPToolBar)

    //{{AFX_MSG_MAP(CXTPToolBarEx)

        // NOTE - the ClassWizard will add and remove mapping macros here.

        //    DO NOT EDIT what you see in these blocks of generated code!

    //}}AFX_MSG_MAP

END_MESSAGE_MAP()



CXTPToolBarEx::CXTPToolBarEx()

{



}



CXTPToolBarEx::~CXTPToolBarEx()

{



}

3. Switch the Toolbars in CMainFrame::OnCreate(). Can do this in two different ways. Both produce the same error:

A.



CXTPToolBar* pToolBar = (CXTPToolBar*)

        pCommandBars->Add(_T("Standard"), xtpBarTop, RUNTIME_CLASS(CXTPToolBarEx));

    if (!pToolBar || !pToolBar->LoadToolBar(IDR_MAINFRAME))

    {

        TRACE0("Failed to create toolbar\n");

        return -1;

    }


 
pCommandBars->SetToolBarClass(RUNTIME_CLASS(CXTPToolBar Ex));

CXTPToolBar* pToolBar = (CXTPToolBar*)

        pCommandBars->Add(_T("Standard"), xtpBarTop);

    if (!pToolBar || !pToolBar->LoadToolBar(IDR_MAINFRAME))

    {

        TRACE0("Failed to create toolbar\n");

        return -1;

    }

4. Build and run it. When you try to close the app, it will give you the error.

Please help. I need to find a fix for this fairly soon. Any help is appreciated. Thanks!

You must instead DECLARE_DYNCREATE/IMPLEMENT_DYNCREATE

use

DECLARE_XTP_COMMANDBAR/IMPLEMENT_XTP_COMMANDBAR

ps. For custom CXTPControl:

DECLARE_XTP_CONTROL/IMPLEMENT_XTP_CONTROL

Oleg,

Thanks for the reply. Your PS saved me!

However, I found out the hard way that one should not use pointers to controls in a toolbar. It seems that LoadCommandBars() creates new objects. So, anytime I need to reference a control, I have to use the FindControl() method. It is no big deal and it is better programming methodology.

Thanks again for your help!!!
