I met problem in CXTCaption::Create()

Method CXTCaption::Create() has next code

 

if (HasCloseButton())
{
  // Create the caption's close button.
  if (!m_btnCaption.Create(NULL, WS_VISIBLE|WS_CHILD|BS_ICON|BS_OWNERDRAW|BS_CENTER|BS_VCENTE R,
    CRect(0,0,0,0), this, XT_IDC_BTN_CLOSE))
  {
    TRACE0( "Unable to create caption button.\n" );
    return -1;
  }
  // Create the image list used by frame buttons.
  m_ilButton.Create (XT_IDB_BTN_OUT, 16, 1, RGB(255,0,255));
  // and set the icon for the caption's close button
  m_btnCaption.SetIcon( CSize( 16, 15 ), m_ilButton.ExtractIcon( 2 ) );
}

 

I have problem in m_ilButton.ExtractIcon() because it doesn't check result from m_ilButton.Create() and if it is false then m_ilButton.ExtractIcon( ) fails.
