CXTColorPicker 'Automatic' color

It is up to you to code what Automatic does, but there isn't an option I saw to remoev the button if you don't want it. What I did was basically copy a little bit and modify from the CodeJock source:

//.h file
class CXTColorPickerEx : public CXTColorPicker
{
    DECLARE_DYNAMIC(CXTColorPickerEx)
public:
    afx_msg void OnShowPopup();
    DECLARE_MESSAGE_MAP()
};
class CXTColorPopupEx : public CXTColorPopup
{
protected:
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    DECLARE_MESSAGE_MAP()
};

//.cpp file

const UINT WM_XT_SHOWPOPUP = (WM_XTP_CONTROLS_BASE + 29);

IMPLEMENT_DYNAMIC(CXTColorPickerEx, CXTColorPicker)

BEGIN_MESSAGE_MAP(CXTColorPickerEx, CXTColorPicker)
    ON_MESSAGE_VOID(WM_XT_SHOWPOPUP, OnShowPopup)
END_MESSAGE_MAP()

void CXTColorPickerEx::OnShowPopup()
{
    CRect rcWindow;
    GetWindowRect(&rcWindow);

    CXTColorPopupEx *pColorPopup = new CXTColorPopupEx(TRUE, 0); //use Ex version
    pColorPopup->Create(rcWindow, this, m_dwPopup, GetColor(), GetDefaultColor());
    pColorPopup->SetFocus();
}

BEGIN_MESSAGE_MAP(CXTColorPopupEx, CXTColorPopup)
    ON_WM_CREATE()
END_MESSAGE_MAP()

int CXTColorPopupEx::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    m_rcBorders.top -= 27;

    CXTColorPopup::OnCreate(lpCreateStruct);

    CRect rect;
    GetWindowRect(&rect);
    rect.bottom -= 27;
    MoveWindow(rect, FALSE);

    return 0;
}
