Text loading to richedit?

I''m not sure if it will work or not, but have you checked out the SetWindowText() function? (if you''re using MFC)

You are unique. Just like everybody else.

you can use WM_SETTEXT or EM_SETTEXTEX

Great, thanks!

Here''s how you can do it (I''m using WTL)

EDITSTREAM es;
es.dwCookie = (DWORD)&m_ReportText; // m_ReportText is a WTL::CString

es.dwError = 0;
es.pfnCallback = StreamReadCallback;
m_RichEdit.StreamIn(SF_TEXT|SF_UNICODE, es);
if(es.dwError)
{
	::MessageBox(NULL,L"Error opening report text", L"Error", MB_OK);
	this->EndDialog(es.dwError);
	return 0;
}

and here''s the callback funcion. dwCookie is the WTL::CString that I want loaded

	static DWORD CALLBACK StreamReadCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG FAR *pcb)
	{
		_ASSERTE(dwCookie != 0);
		_ASSERTE(pcb != NULL);
		WTL::CString* tmp = (WTL::CString*)dwCookie;

		long lng = tmp->GetLength();
		if(lng > cb)
		{
			memcpy(pbBuff, tmp->Left(cb),cb);
			*tmp = tmp->Mid(cb);
			*pcb = cb;
			return 0;
		}
		else if(lng > 0)
		{
			memcpy(pbBuff, tmp->Left(lng),lng);
			*tmp = tmp->Mid(lng);
			*pcb = lng;
			return 0;
		}
		if(lng == 0)
		{
			*pcb = 0;
			return 0;
		}
		return 0;
	}

One thing to note, I stumbled onto some issues with the RTF control not displaying advanced RTF files
using the following will fix this:

::SendMessage(m_RichEdit.m_hWnd, EM_SETTYPOGRAPHYOPTIONS, TO_ADVANCEDTYPOGRAPHY, TO_ADVANCEDTYPOGRAPHY );
