How To Show Container's Toolbar During Inplace Activation

MORE INFORMATION

During inplace activation, MFC shows and hides control bars that have the CBRS_HIDE_INPLACE style used in the COleClientItem::OnShowControlBars() function, which can be found in the MFC source code (Olecli2.cpp).

MFC automatically adds the CBRS_HIDE_INPLACE style to toolbars that are created with the ID AFX_IDW_TOOLBAR, which is the default value for the toolbar created by AppWizard in the MainFrame window (m_wndToolBar). You can see this in the CToolBar::Create() function in the MFC source code (Bartool.cpp). To remove the CBRS_HIDE_INPLACE style from m_wndToolBar, add the following line of code to the CMainFrame::OnCreate function after m_wndToolBar is created:

   m_wndToolBar.SetBarStyle(m_wndToolBar.GetBarStyle()
                            ^ CBRS_HIDE_INPLACE);
				

The SetBarStyle() call removes the CBRS_HIDE_INPLACE style by performing a bitwise XOR operation with the existing style for the toolbar.

NOTE: The resulting behavior depends on the server's implementation. For example, Word 6.0 always puts its toolbar at position (0,0). In this case, Word's toolbar will be placed in front of the container's toolbar. Most servers place their toolbar beneath the container's toolbar as expected.
