Dear Dr. GUI:

I have a CToolBar object in a CWnd derived class. During the CWnd derived class's OnCreate member, I call the CToolBar's Create member (I used code similar to that in the MAINFRM.CPP file of an AppWizard-generated application). It looks like this:

// create button bar
if (!m_buttonBar.Create(this, WS_CHILD | WS_VISIBLE | CBRS_TOP | CBRS_TOOLTIPS)
    ||!m_buttonBar.LoadBitmap(IDB_BUTT_BAR) 
    ||!m_buttonBar.SetButtons(bButtons, sizeof(bButtons) / sizeof(UINT)))
{
  TRACE0("Failed to create Button Bar\n");
  return -1;      // fail to create
}

The m_buttonBar object is a CToolBar object declared in the CWnd class header. I do not want the toolbar to be "dockable" or "floatable," so I removed the CBRS_FLYBY flag and do not call EnableDocking. The code appears to execute OK (there are no assertions), but the toolbar never appears!

Dr. GUI replies:

You should probably set the size of the toolbar. By default the width and height are (0, 0) since the CFrameWnd class controls its size (see CWnd::MoveWindow).
