// Acknowledgements:
//  o   Thanks to Harlan R. Seymour ([e-mail]) for motivating me
//      to update this code. Also he prompted me to a bug durring 
//      the developement phase.
//  o   Thanks to Zafir Anjum ([e-mail]) for publishing this
//      code on his cool site (www.codeguru.com).
//  o   Some ideeas for the gripper came from the CToolBarEx flat toolbar
//      by Joerg Koenig ([e-mail]). Also he inspired
//      me on writting this notice:) . Thanks, Joerg!
//  o   Thanks to Jakawan Ratiwanich ([e-mail]) and to
//      Udo Schaefer([e-mail]) for the dwStyle bug fix under
//      VC++ 6.0.
//  o   Thanks to Microsoft developers for the MFC source code. After
//      all, most of this class code came from there.
//
/////////////////////////////////////////////////////////////////////////
//
// Usage:
// o    Derive your class from CSizingControlBar. Then create your child
//      controls/windows on it.
// o    Include your class header in Mainfrm.cpp and add a member 
//      variable to CMainFrame. In CMainFrame::OnCreate(), create the
//      control bar, enable it to dock, and so on... like a toolbar or
//      any control bar.
// o    More details at
//      http://www.codeguru.com/docking/docking_window.shtml or search
//      http://www.codeguru.com for my name if the article has moved.
