actually when I follow the provided link and execute the demo project I find
that it has the same problem. It completely ignores the pict part. Could you
send me the sample project you made? You were able to see the smiley. I'm
completely stupified now. Maybe c++ is using the wrong component?
Why are you subclassing the control that way?
What happens when you use DDX_Control?
I created a sample program with a Rich Edit control in it. Loaded the rtf
data you included in the message and I could see the not so smiling smiley.
Take a look at this on how to subclass a RichEdit control. CAutoRichEditCtrl
is also a usful start to creating your own CRichEditCtrl derived class.

I'm making a richedit control in mfc and i'm encountering a few problems.
Let
me first situate the problem.
The control is subclassed as such
BOOL CSodeXRichTextCtrl::PreCreateWindow(CREATESTRUCT& cs)
{
cs.lpszClass = _T("RichEdit20W");
......
return COleControl::PreCreateWindow(cs);
}
I've implemented a SelRTF property:
DWORD CALLBACK CSodeXRichTextCtrl::EditStreamCallback(DWORD_PTR dwCookie,
LPBYTE pbBuff, LONG cb, LONG *pcb)
{
CString *pstr = (CString *)dwCookie;
USES_CONVERSION;
if( pstr->GetLength() < cb )
{
*pcb = pstr->GetLength();
memcpy(pbBuff, T2CA((LPCTSTR)*pstr), *pcb );
pstr->Empty();
}
else
{
*pcb = cb;
memcpy(pbBuff, T2CA((LPCTSTR)*pstr), *pcb );
*pstr = pstr->Right( pstr->GetLength() - cb );
}
return 0;
}
void CSodeXRichTextCtrl::SetSelRTF(LPCTSTR newVal)
{
USES_CONVERSION;
AFX_MANAGE_STATE(AfxGetStaticModuleState());
rtftext = new CString(newVal);
EDITSTREAM es;
es.dwCookie = (DWORD)rtftext;
es.dwError = 0;
es.pfnCallback = (EDITSTREAMCALLBACK)&EditStreamCallback;
DWORD flags;
//is het rtf of gewone tekst
if (rtftext->Left(5).Compare(_T("{\\rtf")) == 0 ||
rtftext->Left(5).Compare(_T("{urtf")) == 0)
flags = SF_RTF | SFF_SELECTION;
else
flags = SF_TEXT | SFF_SELECTION;
::SendMessage(m_hWnd, EM_STREAMIN, (WPARAM) flags, (LPARAM) &es);
SetModifiedFlag();
}
This works perfect for rtf text and formatting. However the problem starts
when i want to stream in an image:
{\rtf1\ansi\ansicpg1252\deff0\deflang2067{\fonttbl{\f0\fnil\fcharset0
Onyx;}}
{\colortbl ;\red128\green128\blue128;}

test\par
}
The above text only shows me the word test (as it should) but isn't
followed
by the image. The control seems to ignore the {pict part completely. So I
get
the following output
test test
instead of
test (image) test
When I use the above rtf codes on the selRTF property of a microsoft rich
edit control ocx (vb6) the image get showed.
What aim I doing wrong?
Problem 2: when I use my control on vb form and press an arrow key to
browse
trough my text it acts as a tab key and gives focus to the next tab index.
Any ideas why?
Thank you very much
