Hi Team,

The problem with the docked control bar layout is not fixed in 2.88  when you use a bar from the tabbed document that you change it to the dockable state and it come to floating state (not docked) and than you try to dock it in a sid by side position of an already docked bar, both bars desappear, the layout is not good.  If you just resize the MainFrame than the layout is refresh  correctly.

Thanks.

Stephane.

P.S. I reproduce the problem with your SDI_DynamicBars sample.

It looks like we fixed this issue. Please update the source code for the following method:

// dock control bar relatively to other control bar using
// space percent specification (extended version)
bool CExtControlBar::DockControlBarLTRB(
      int nPercentToOccupy, // greater than zero and less than one hundred
      CExtControlBar * pBarTarget,
      UINT nDockBarID, // = AFX_IDW_DOCKBAR_BOTTOM
      bool bRecalcLayout // = true
      )
{
      ASSERT_VALID( this );
      ASSERT_KINDOF( CExtControlBar, this );
