CRichEditCtrl

[esdee]

hi
i have a CRichEditCtrl in my app and it can't open UNICODE files properly (opens ANSI files ok). what do i have to do ?
here's part of my code:
CRichEditCtrl * richedit = (CRichEditCtrl *)GetDlgItem(IDC_RICHEDIT1);
CFile file(filename, CFile::modeRead);

EDITSTREAM es;

es.dwCookie = (DWORD) &file;
es.pfnCallback = MyStreamInCallback;
richedit->StreamIn(SF_TEXT, es);

richedit->SetReadOnly();


the callback is straight from msdn i think ..
static DWORD CALLBACK
MyStreamInCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
CFile* pFile = (CFile*) dwCookie;

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

return 0;
}

Could be a number of things.

1) Are you running Windows 95/98/ME? Those OSes don't support unicode at all.

2) By "unicode" do you mean UTF-8? If so, you will have to decode the UTF-8 before passing it into the rich edit.

3) MFC's Rich Edit control means Version 1 of the control, whose WNDCLASS is called "RichEdit". The newer version 2 has a WNDCLASS called "RichEdit20A" or "RichEdit20W" (for ANSI or Unicode, respectively). If you want a newer richedit, you can't use the convenient MFC classes, but the "RichEdit20W" might provide proper support for Unicode data.

4) Richedit has always been buggy.

Cheers!
