怎么把CRichEditView中的数据保存到数据库

[ToperRay]

可以先保存成RTF,然后把RTF数据转换成数据库的内容

CRichEditCtrl::StreamOut
Parameters
nFormat
Flags specifying the output data formats. See the Remarks section for more information.

es
EDITSTREAM structure specifying the output stream. See the Remarks section for more information.

Return Value
Number of characters written to the output stream.

Remarks
The value of nFormat must be one of the following:

SF_TEXT Indicates writing text only.

SF_RTF Indicates writing text and formatting.

SF_RTFNOOBJS Indicates writing text and formatting, replacing OLE items with spaces.

SF_TEXTIZED Indicates writing text and formatting, with textual representations of OLE items.

Any of these values can be combined with SFF_SELECTION. If SFF_SELECTION is specified, StreamOut writes out the current selection into the output stream. If it is not specified, StreamOut writes out the entire contents of this CRichEditCtrl object.

In the EDITSTREAM parameter es, you specify a callback function which fills a buffer with text. This callback function is called repeatedly, until the output stream is exhausted.

For more information, see EM_STREAMOUT message and EDITSTREAM structure in the Windows SDK.

Example
Visual C++ Copy Code
// My callback procedure that writes the rich edit control contents
// to a file.
static DWORD CALLBACK
MyStreamOutCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
CFile* pFile = (CFile*) dwCookie;

pFile->Write(pbBuff, cb);
*pcb = cb;

return 0;
}

我现在可以保存了,但是不知道怎么从数据库中读取到CRichEditView

DWORD CALLBACK MyStreamInCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)//读取
{
 	ADO* myado=(ADO*)dwCookie;//theApp.m_Ado;
	CString str_sql;
	myado->OnInitADO();
	CMainFrame* m_pMf=(CMainFrame*)AfxGetApp()->GetMainWnd();
	str_sql.Format("Select D_CONTENT FROM T_TREE WHERE d_TREEID=%ld",m_pMf->m_wndTree.GetCurTreeID());
	myado->m_pRecordset=myado->GetRecordSet((_bstr_t)str_sql);
	pbBuff=(LPBYTE)(TCHAR*)(_bstr_t)myado->m_pRecordset->GetCollect("D_CONTENT");
	*pcb=0;
   return 0;
}
void CENBView::SetRtf(ADO ado)//CFile* pInputFile )
{
	ADO &myado=theApp.m_Ado;
	EDITSTREAM es;
	es.dwError = 0;
	es.pfnCallback = MyStreamInCallback;
	es.dwCookie = (DWORD)&myado;//(DWORD)pRs;//pInputFile;
	CRichEditCtrl &m_edit = GetRichEditCtrl();
	m_edit.StreamIn(SF_RTF, es);	// Do it.
	// Read the text in
}

不知道你想把其中的数据按怎么样的格式，逐条放进数据库中
