我的任务
分享win32 richedit 如何插入图片?
1. 环境:
Windows, C++, vs2008, RichEdit2或者3. win32编程(非采用MFC的方式)
2. 参照的代码: http://msdn.microsoft.com/en-us/library/dd387916%28v=vs.85%29.aspx
3. 问题:
1). 当前通过ole的方式可以插入bmp图片. 问题是: 插入图片后,在图片的下面会有图片的文件名. 这个并不是我想要的. 如下图(图中的scroll.bmp不是我想要的)
2). 请问:
.如何去掉多余的文件名.(即在插入图片之后不显示图片的文件名)
.或者: 有另外的方法插入图片.
请您 附上关键性代码. 若您的代码采用, 悬赏分都给您.
请您 直接回帖, 或者发给我的email: AFRL@163.com
多谢!

刚试了一下在Word 2003中插入一个图片对象，然后将图片下面的文件名隐藏的步骤，供楼主参考：
在图片对象上点右键、选“包 对象”、编辑包、弹出“对象包装程序”，再选编辑、标签、将标签文字删除、确定。文件、更新。关闭“对象包装程序”。

建议楼主移驾VC/MFC论坛问问。

几乎各个flag组合都用了,还是不好用...
是不是那里弄错了, 是不是还有其它的方式...

以下是我的伪代码, reobject.dwFlags 我用的以下的组合, 貌似还是没有解决 存在文件名的问题:

REOBJECT Structure
--------------------------------------------------------------------------------
The REOBJECT structure contains information about an object.
Syntax
typedef struct _reobject {
DWORD cbStruct;
LONG cp;
CLSID clsid;
LPOLEOBJECT poleobj;
LPSTORAGE pstg;
LPOLECLIENTSITE polesite;
SIZEL sizel;
DWORD dvaspect;
DWORD dwFlags;
DWORD dwUser;
} REOBJECT;
Members
cbStruct
Structure size, in bytes.
cp
Character position of the object.
clsid
Class identifier of the object.
poleobj
Points to an instance of the IOleObject interface for the object.
pstg
Points to an instance of the IStorage interface. This is the storage object associated with the object.
polesite
Points to an instance of the IOleClientSite interface. This is the object's client site in the rich edit control. This address must have been obtained from the IRichEditOle::GetClientSite method.
sizel
A SIZEL structure specifying the size of the object. The unit of measure is 0.01 millimeters, which is a himetric measurement. For more information, see function GetMapMode. A 0, 0 on insertion indicates that an object is free to determine its size until the modify flag is turned off.
dvaspect
Display aspect used. See DVASPECT for an explanation of possible values.
dwFlags
Object status flag. It can be a combination of the following values.
REO_BELOWBASELINE
Object sits below the baseline of the surrounding text; the default is to sit on the baseline.
REO_BLANK
Object is new. This value gives the object an opportunity to save nothing and be deleted from the control automatically.
REO_DONTUSEPALETTE
Object is rendered before the creation and realization of a half-tone palette. Applies to 32-bit platforms only.
REO_DYNAMICSIZE
Object always determines its extents and may change despite the modify flag being turned off.
REO_GETMETAFILE
The rich edit control retrieved the metafile from the object to correctly determine the object's extents. This flag can be read but not set.
REO_HILITED
Object is currently highlighted to indicate selection. Occurs when focus is in the control and REO_SELECTED is set. This flag can be read but not set.
REO_INPLACEACTIVE
Object is currently inplace active. This flag can be read but not set.
REO_INVERTEDSELECT
Object is to be drawn entirely inverted when selected; the default is to be drawn with a border.
REO_LINK
Object is a link. This flag can be read but not set.
REO_LINKAVAILABLE
Object is a link and is believed to be available. This flag can be read but not set.
REO_OPEN
Object is currently open in its server. This flag can be read but not set.
REO_RESIZABLE
Object may be resized.
REO_SELECTED
Object is currently selected in the rich edit control. This flag can be read but not set.
REO_STATIC
Object is a static object. This flag can be read but not set.
dwUser
Reserved for user-defined values.
Structure Information
Header Declared in Richedit.h
Minimum operating systems Windows 95, Windows NT 4.0

richedit-8 的Minimum supported client 为windows 8:

谢谢 zhao4zhong1 和 derekrose.
zhao4zhong1, 我的代码插入的是真实的图片,并非链接.
derekrose, richedit-8之前大概看过, 但貌似对os 版本要求比较高, 我们的用户还有用 Windows Xp 的. 我想如果我通过 条件编译来写代码, 解决了高os版本的问题, 但问题是如果解决Xp系统下插入图片的问题.

插入图片的链接和插入图片数据不是一回事。我猜。
