Following advice in Forum posts to control which buttons are displayed in CExtDynamicControlBar, I override CExtDynamicControlBar::OnNcAreaButtonsReinitialize().
However, if I tab-dock any control bars, the following method gets called, and creates buttons that I didn’t want. Can you suggest how I can get around this problem?
void CExtDynamicTabbedControlBar::OnNcAreaButtonsReinitialize()
{
ASSERT_VALID( this );
INT nCountOfNcButtons = NcButtons_GetCount();
if( nCountOfNcButtons > 0 )
return;
NcButtons_Add( new CExtDynamicBarNcAreaButtonClose(this) );
NcButtons_Add( new CExtDynamicBarNcAreaButtonAutoHide(this) );
NcButtons_Add( new CExtDynamicBarNcAreaButtonMenu(this) );
}
Here’s a sample call-stack when I perform some code-driven tab-docking (as opposed to drag-n-drop), if it is of any use to you.

Perhaps I should also mention: the unwanted buttons go away once the affected control bars are no longer tab-docked.

To get control over the caption buttons in tabbed bar containers, you need to make Prof-UIS using your own CExtDynamicTabbedControlBar-derived class which should manage its buttons. This class is also kind of CExtControlBar. Just override the CExtDynamicBarSite::OnDbsCreateTabbedBarInstance() virtual method and return an instance of your tabbed bar container:
CExtDynamicTabbedControlBar *
CMainFrame::OnDbsCreateTabbedBarInstance() const
{
ASSERT( this != NULL );
CExtDynamicTabbedControlBar * pBar =
new C_YOUR_DynamicTabbedControlBar;
return pBar;
}CExtDynamicBarSite class, which we sent you be e-mail.
