A Resizeable Dialog Bar

     Environment: Win95 VC++4.1
     
     Is it possible to resize a Dialog Bar when it is undocked? I have 
     created it with code like this:
     
     m_pGraphBar = new CBarGraph(m_pMainWnd);
     
     BOOL ok = m_pGraphBar->Create( m_pMainWnd, CBRS_BOTTOM|CBRS_FLYBY| 
     CBRS_SIZE_DYNAMIC,IDD_GRAPHBAR);
     
     m_pGraphBar->EnableDocking(CBRS_ALIGN_TOP | CBRS_ALIGN_BOTTOM); 
     pMainFrame->DockControlBar(m_pGraphBar);
     
     CBarGraph is a Class derived from CDialogBar as discussed previously 
     around here.
     
     When The DialogBar is undocked I see the resizing arrows when I try to 
     resize and Spy++ shows WM_WINDOWPOSCHANGING Messages are going to the 
     Dialog.
     
     As you can see I have 'CBRS_SIZE_DYNAMIC' Flag set. 
     
     Question:
     
     Is it possible to handle WM_WINDOWPOSCHANGING in a CDialogBar class? 
     Class Lizzard doesnt Show it.

Read the C/C++ KBase article Q143255: How to make a resizable dialog bar. It
might help.

Have you overridden CalcDynamicLayout() in your CDialogBar derived class?
Take a look at an article on the msdn =22How to make a resizable dialog   =
Bar=22 to see sample code.

Look instead at overriding CalcDynamicLayout.  Handling WM_WINDOWPOSCHANGING 
within a CDialogBar would not directly affect the size of the CMiniFrameWnd.  
However, controlling the size of your dialog bar through CalcDynamicLayout will 
affect the CMiniFrameWnd size.

Note that CalcDynamicLayout is a member of CControlBar, the base class to 
CDialogBar.  Override away.
