在MDI程序中如何将RichEdit的内容存入数据库中？

[qiek]

工程中有CChildFrame、CMainFrame、CMyApp、CMyCntrItem、CMyDoc、CMyView，
将RichEdit中的内容（包含插入的图片,OLE对象）等直接存入数据库中应该重载哪个类的哪个方法？

最好能给你代码示例。

msdn:


static DWORD CALLBACK
MyStreamOutCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
CFile* pFile = (CFile*) dwCookie;

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

return 0;
}

// The example code.
// The pointer to my rich edit control.
extern CRichEditCtrl* pmyRichEditCtrl;
// The file to store the contents of the rich edit control.
CFile cFile(TEXT("myfile.rtf"), CFile::modeCreate|CFile::modeWrite);
EDITSTREAM es;

es.dwCookie = (DWORD) &cFile;
es.pfnCallback = MyStreamOutCallback;
pmyRichEditCtrl->StreamOut(SF_RTF, es);
