I want to show some news in my Ribbon Bar, just liking CEdit works is ok. How can I do that?

Thank you!

You should create your CExtBarTextFieldButton-derived class which implements the CExtBarTextFieldButton::RibbonILV_CalcSize() virtual method for computing custom size of text field and the CExtBarTextFieldButton::OnInplaceControlCreate() virtual method for creating the multi-line in-pace editor control (just invoke parent class method and add the ES_MULTILINE style to the created by default editor window). This method can return NULL if you want to make text field non-editable. You should also implement the CExtBarTextFieldButton::PaintCompound() virtual method for painting multi-line text in the text field because by default text fields are single line.
Next step is to create your own ribbon node which instantiates the multiline text field button:

class __PROF_UIS_API CYourNewsRibbonNode : public CExtRibbonNode
            DECLARE_SERIAL( CYourNewsRibbonNode );
                        UINT nCmdIdBasic = 0L,
                        UINT nCmdIdEffective = 0L,
                        CExtRibbonNode * pParentNode = NULL,
                        DWORD dwFlags = 0L,
                        __EXT_MFC_SAFE_LPCTSTR strTextInToolbar = NULL,
                        __EXT_MFC_SAFE_LPCTSTR strTextInMenu = NULL,
                        __EXT_MFC_SAFE_LPCTSTR strTextUser = NULL,
                        LPARAM lParam = 0L,
                        CExtCmdIcon * pIconCustomized = NULL
                        INT nTextFieldWidth = 100,
                        INT nDropDownWidth = -2, // (-1) - auto calc, (-2) - same as button area
                        INT nDropDownHeightMax = 250
#endif // (!defined __EXT_MFC_NO_BUILTIN_TEXTFIELD)
            virtual ~CYourNewsRibbonNode();
            virtual CRuntimeClass * _OnRibbonGetButtonRTC();

The _OnRibbonGetButtonRTC() method should simply return the RUNTIME_CLASS of your text field button.
Now you can use the CYourNewsRibbonNode class in your ribbon command tree and it will instantiate the multiline text field.
