How catch click event?

 i use Task Panel in dialog.

 i insert following code in dialog on InitialUpdate function.

     pItem = pGroup->AddLinkItem(0, IDI_SENT_ITEMS);
    pItem->SetCaption(_T("Test 1"));

 i hope to catch in my dialog when user click item.

 how?

 where is the reference sourcecode?
 please tell me. where is....


 i found code with XTPWM_TASKPANEL_NOTIFY keyword.
 
but, event not enter in code.

 LRESULT Cg3OutlookBarContainer::OnTaskPanelNotify(WPARAM wParam, LPARAM lParam)


 

of cause, I had typed.
but, not receive message.

BEGIN_MESSAGE_MAP(Cg3OutlookBarContainer, CTaskPanelBase)
    //{{AFX_MSG_MAP(CTaskPanel)
        // NOTE - the ClassWizard will add and remove mapping macros here.

        ON_MESSAGE(XTPWM_TASKPANEL_NOTIFY, OnTaskPanelNotify)

    //}}AFX_MSG_MAP
    ON_WM_LBUTTONUP()
END_MESSAGE_MAP()

It works.
