Oleg,

Thanks for the reply. Your PS saved me!

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

Thanks again for your help!!!

You must instead DECLARE_DYNCREATE/IMPLEMENT_DYNCREATE

use

DECLARE_XTP_COMMANDBAR/IMPLEMENT_XTP_COMMANDBAR

ps. For custom CXTPControl:

DECLARE_XTP_CONTROL/IMPLEMENT_XTP_CONTROL

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!
