Class A
{
cstring m_strName;
A* m_pNext;
}

Class B
{
std::list<A> m_list;
}


//allocate some global memory
HGLOBAL clipbuffer;
EmptyClipboard();
clipbuffer = GlobalAlloc(GMEM_MOVEABLE, sizeof(B));
B* buffer = (B*)GlobalLock(clipbuffer);
//put the data into that memory
memcpy(GlobalLock(buffer), (void*)pQDObj, sizeof(B));
//Put it on the clipboard
GlobalUnlock(clipbuffer);
SetClipboardData(format,clipbuffer);
CloseClipboard();

这样写B中的list没有办法保存到剪贴板中,请问高手这种情况怎么处理?

急急急!!!!

This article explains how to expand the list of supported formats, particularly for OLE support. The article Clipboard: Copying and Pasting Data describes the minimum implementation necessary to support copying and pasting from the Clipboard. If this is all you implement, the only formats placed on the Clipboard are CF_METAFILEPICT, CF_EMBEDSOURCE, CF_OBJECTDESCRIPTOR, and possibly CF_LINKSOURCE. Most applications will need more formats on the Clipboard than these three.

Registering Custom Formats
To create your own custom formats, follow the same procedure you would use when registering any custom Clipboard format: pass the name of the format to the RegisterClipboardFormat function and use its return value as the format ID.

Placing Formats on the Clipboard
To add more formats to those placed on the Clipboard, you must override the OnGetClipboardData function in the class you derived from either COleClientItem or COleServerItem (depending on whether the data to be copied is native). In this function, you should use the following procedure.

To place formats on the Clipboard

Create a COleDataSource object.


Pass this data source to a function that adds your native data formats to the list of supported formats by calling COleDataSource::CacheGlobalData.


Add standard formats by calling COleDataSource::CacheGlobalData for each standard format you want to support.
This technique is used in the MFC OLE sample program HIERSVR (examine the OnGetClipboardData member function of the CServerItem class). The only difference in this sample is that step three is not implemented because HIERSVR supports no other standard formats.

        VC/MFC社区版块或许是CSDN最“古老”的版块了,记忆之中,与CSDN的年龄几乎差不多。随着时间的推移,MFC技术渐渐的偏离了开发主流,若干年之后的今天,当我们面对着微软的这个经典之笔,内心充满着敬意,那些曾经的记忆,可以说代表着二十年前曾经的辉煌……
        向经典致敬,或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天,我们期待着MFC技术能够恢复其曾经的辉煌,或许这个期待会永远成为一种“梦想”,或许一切皆有可能……
        我们希望这个版块可以很好的适配Web时代,期待更好的互联网技术能够使得MFC技术框架得以重现活力,……
