 * User: Kirk Stowell Date: 5/11/99    Time: 10:02p
 * Updated in $/CodeJockey/CJ60Lib
 * After much frustration, a class re-write. Fixed many of the issues with
 * painting, invalid pointers and memory leaks. Added document support for
 * views associated with the tab control.
 * 
 * *****************  Version 8  *****************
 * User: Kirk Stowell Date: 4/14/99    Time: 11:53p
 * Updated in $/CodeJockey/CJ60Lib
 * Added context popupMenu for CJTabCtrl to use Brent Corkum's BCMenu (CCJMenu).

 * 
 * *****************  Version 6  *****************
 * User: Kirk Stowell Date: 3/14/99    Time: 11:51p
 * Updated in $/CodeJockey/CJ60Lib
 * Gonzalo Pereyra [ persys@adinet.com.uy ] - I wanted to trap NM_RETURN
 * notifications in my CTreeView Class. I couldn't... It turns out that
 * CControlbar::PreTranslateMessage() will eat all dialog messages...It
 * will never get dispatched to my window. So I Overrided it in :
 * CCJTabCtrlBar::PreTranslateMessage(). this will allow for message
 * reflection and we will get NM_RETURN. I don't know if this a good
 * solution but for now , it works.
 * 
 * *****************  Version 5  *****************
 * User: Kirk Stowell Date: 2/24/99    Time: 11:49p
 * Updated in $/CodeJockey/CJ60Lib
 * Phil Baxter [pgb@mrjinx.demon.co.uk] - Fixed the following problems
 * when tabs are added after creation:
 * 1. The tab was created, but the view that was showing on the tab was
 * not visible.
 * 2. Get an assertion when the AddView function attempts to perform the
 * AddTool function.
 * 3. When a new view is added, although you set it to be the active view,
 * it isn't raised to the top of the stack in the display.
 * 4. The Tab name as stored in the TCB_ITEM structure is now a CString,
 * this removes the 32 byte limit that it previously had.
 * 5. New methods for obtaining the name as stored in the TCB_ITEM
 * structure.
 * 6. New Methods for deleting a view from the control, this removes the
 * view entirely including its 	associated tab.
 * 7. Some minor fixes around assertions when trying to manipulate the
 * control when it has not had any tabs created.
 * 8. Added two new member functions:
 * void SetViewToolTip(int nView, LPCTSTR lpszLabel);
 * void SetViewToolTip(CRuntimeClass *pViewClass, LPCTSTR lpszLabel);
 * 
 * *****************  Version 4  *****************
 * User: Kirk Stowell Date: 1/31/99    Time: 11:48p
 * Updated in $/CodeJockey/CJ60Lib
 * Commented out 2 calls to SetActiveView(). This somewhat fixes the
 * problem with CTRL+TAB in activatation of MDI child windows, however if
 * you click inside the view, this breaks CTRL+TAB again, will look at
 * this when I get some free time. Thanks to Pierre Guimont
 * (Pierre_Guimont@mitel.com) for pointing this out.
 * 
 * Added m_TabCtrl.GetRowCount() as per Rashid Thadha
 * rashidt@consort.co.uk) request.
 * 
 * *****************  Version 3  *****************
 * User: Kirk Stowell Date: 1/17/99    Time: 11:46p
 * Updated in $/CodeJockey/CJ60Lib
 * Added helper class CCJTabCtrl to eliminate re-painting problems such as
 * when the app is minimized then restored.
 * 
 * *****************  Version 2  *****************
 * User: Kirk Stowell Date: 1/03/99    Time: 11:46p
 * Updated in $/CodeJockey/CJ60Lib
 * Application freezing bug fixed by
 * LiangYiBin.Donald(mailto:lybd@yahoo.com)
 * 
 * *****************  Version 1  *****************
 * User: Kirk Stowell Date: 10/17/98   Time: 11:45p
 * Created in $/CodeJockey/CJ60Lib
 * Initial re-write and release.
