本文详细介绍了atlctrls.h文件中CRichEditCtrlT类的修改，包括封装函数、模板类CImageList、新增查找函数FindItem、获取工具栏上下拉框矩形大小函数GetItemDropDownRect、添加分隔线函数InsertSeparator和AddSeparator、RichEdit控件宏定义变化、新增RichEdit8相关函数等。

atlctrls.h中是对控件的封装。

第1249行增加：

void GetMargins(UINT& nLeft, UINT& nRight) const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    DWORD dwRet = (DWORD)::SendMessage(m_hWnd, EM_GETMARGINS, 0, 0L);
    nLeft = LOWORD(dwRet);
    nRight = HIWORD(dwRet);
  }

没什么好说的，原来的函数是以返回值的方式获取：

DWORD GetMargins() const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (DWORD)::SendMessage(m_hWnd, EM_GETMARGINS, 0, 0L);
  }

第1858行，CImageList变成了模板类，增加了自动销毁模板开头：

// forward declarations
template <bool t_bManaged> class CImageListT;
typedef CImageListT<false>   CImageList;
typedef CImageListT<true>    CImageListManaged;


template <bool t_bManaged>
class CImageListT
{
public:
// Data members
  HIMAGELIST m_hImageList;

// Constructor/destructor/operators
  CImageListT(HIMAGELIST hImageList = NULL) : m_hImageList(hImageList)
  { }

  ~CImageListT()
  {
    if(t_bManaged && (m_hImageList != NULL))
      Destroy();
  }

第3706行，CListViewCtrlT.FindItem 增加了一个重载：

int FindItem(LPCTSTR lpstrFind, bool bPartial = true, bool bWrap = false, int nStart = -1) const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    LVFINDINFO lvfi = { 0 };
    lvfi.flags = LVFI_STRING | (bWrap ? LVFI_WRAP : 0) | (bPartial ? LVFI_PARTIAL : 0);
    lvfi.psz = lpstrFind;
    return (int)::SendMessage(m_hWnd, LVM_FINDITEM, nStart, (LPARAM)&lvfi);
  }

查找ListView item时不用费劲地填结构体了。

第5819行，CToolBarCtrlT增加GetItemDropDownRect：

void GetItemDropDownRect(int nIndex, LPRECT lpRect) const
  {
#ifndef TB_GETITEMDROPDOWNRECT
    const int TB_GETITEMDROPDOWNRECT = WM_USER + 103;
#endif
    ATLASSERT(::IsWindow(m_hWnd));
    BOOL bRet = (BOOL)::SendMessage(m_hWnd, TB_GETITEMDROPDOWNRECT, nIndex, (LPARAM)lpRect);
    bRet;   // avoid level 4 warning
    ATLASSERT(bRet != FALSE);
  }

用来获取工具栏上下拉框的窗口矩形大小。(_WIN32_WINNT >= 0x0600)

第5934行，CToolBarCtrlT增加：

BOOL InsertSeparator(int nIndex, int cxWidth = 8)
  {
    return InsertButton(nIndex, 0, BTNS_SEP, 0, cxWidth, (INT_PTR)0, 0);
  }

  BOOL AddSeparator(int cxWidth = 8)
  {
    return AddButton(0, BTNS_SEP, 0, cxWidth, (INT_PTR)0, 0);
  }

用来添加工具栏上的分隔线。

第6397行，GetToolTips、SetToolTips中的tips由小写变成了大写Tips……。

第6656行，CTrackBarCtrlT.SetSelStart 和接下来的SetSelEnd、SetSelection增加了bRedraw参数：

void SetSelStart(int nMin, BOOL bRedraw = FALSE)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    ::SendMessage(m_hWnd, TBM_SETSELSTART, bRedraw, (LPARAM)nMin);
  }

第7291行，增加了RichEdit 5的宏定义：

#if !defined(_UNICODE) && (_RICHEDIT_VER >= 0x0500)
  #undef MSFTEDIT_CLASS
  #define MSFTEDIT_CLASS	"RICHEDIT50W"
#endif

这影响到CRichEditCtrlT调用的是哪个版本的RichEdit控件。

static LPCTSTR GetLibraryName()
  {
#if (_RICHEDIT_VER >= 0x0500)
    return _T("MSFTEDIT.DLL");
#elif (_RICHEDIT_VER >= 0x0200)
    return _T("RICHED20.DLL");
#else
    return _T("RICHED32.DLL");
#endif
  }

第7825行，增加CRichEditCtrlT.GetWordBreakProc 和CRichEditCtrlT.SetWordBreakProc ：

EDITWORDBREAKPROC GetWordBreakProc() const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (EDITWORDBREAKPROC)::SendMessage(m_hWnd, EM_GETWORDBREAKPROC, 0, 0L);
  }

  void SetWordBreakProc(EDITWORDBREAKPROC ewbprc)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    ::SendMessage(m_hWnd, EM_SETWORDBREAKPROC, 0, (LPARAM)ewbprc);
  }

第8160行，为RichEdit 8增加的代码：

#if (_RICHEDIT_VER >= 0x0800)
  AutoCorrectProc GetAutoCorrectProc() const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (AutoCorrectProc)::SendMessage(m_hWnd, EM_GETAUTOCORRECTPROC, 0, 0L);
  }

  BOOL SetAutoCorrectProc(AutoCorrectProc pfn)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_SETAUTOCORRECTPROC, (WPARAM)pfn, 0L);
  }

  BOOL CallAutoCorrectProc(WCHAR ch)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_CALLAUTOCORRECTPROC, (WPARAM)ch, 0L);
  }

  DWORD GetEditStyleEx() const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (DWORD)::SendMessage(m_hWnd, EM_GETEDITSTYLEEX, 0, 0L);
  }

  DWORD SetEditStyleEx(DWORD dwStyleEx, DWORD dwMask)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (DWORD)::SendMessage(m_hWnd, EM_SETEDITSTYLEEX, dwStyleEx, dwMask);
  }

  DWORD GetStoryType(int nStoryIndex) const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (DWORD)::SendMessage(m_hWnd, EM_GETSTORYTYPE, nStoryIndex, 0L);
  }

  DWORD SetStoryType(int nStoryIndex, DWORD dwStoryType)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (DWORD)::SendMessage(m_hWnd, EM_SETSTORYTYPE, nStoryIndex, dwStoryType);
  }

  DWORD GetEllipsisMode() const
  {
    ATLASSERT(::IsWindow(m_hWnd));

    DWORD dwMode = 0;
    BOOL bRet = (BOOL)::SendMessage(m_hWnd, EM_GETELLIPSISMODE, 0, (LPARAM)&dwMode);
    bRet;   // avoid level 4 warning
    ATLASSERT(bRet != FALSE);

    return dwMode;
  }

  BOOL SetEllipsisMode(DWORD dwEllipsisMode)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_SETELLIPSISMODE, 0, dwEllipsisMode);
  }

  BOOL GetEllipsisState() const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_GETELLIPSISSTATE, 0, 0L);
  }

  BOOL GetTouchOptions(int nTouchOptions) const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_GETTOUCHOPTIONS, nTouchOptions, 0L);
  }

  void SetTouchOptions(int nTouchOptions, BOOL bEnable)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    ::SendMessage(m_hWnd, EM_SETTOUCHOPTIONS, nTouchOptions, bEnable);
  }

  HRESULT InsertTable(TABLEROWPARMS* pRowParams, TABLECELLPARMS* pCellParams)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (HRESULT)::SendMessage(m_hWnd, EM_INSERTTABLE, (WPARAM)pRowParams, (LPARAM)pCellParams);
  }

  HRESULT GetTableParams(TABLEROWPARMS* pRowParams, TABLECELLPARMS* pCellParams) const
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (HRESULT)::SendMessage(m_hWnd, EM_GETTABLEPARMS, (WPARAM)pRowParams, (LPARAM)pCellParams);
  }

  HRESULT SetTableParams(TABLEROWPARMS* pRowParams, TABLECELLPARMS* pCellParams)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (HRESULT)::SendMessage(m_hWnd, EM_SETTABLEPARMS, (WPARAM)pRowParams, (LPARAM)pCellParams);
  }

  HRESULT InsertImage(RICHEDIT_IMAGE_PARAMETERS* pParams)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (HRESULT)::SendMessage(m_hWnd, EM_INSERTIMAGE, 0, (LPARAM)pParams);
  }

  BOOL SetUiaName(LPCTSTR lpstrName)
  {
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, EM_SETUIANAME, 0, (LPARAM)lpstrName);
  }
