Yeah, but the user has to have RichEdit 2.0 on the system, so make sure you program a fail safe... most will have it but all it takes is that one who doesn't. But any way here you go.

<br />
	<br />
	// Initiallize<br />
	HANDLE m_hRichEdit2 = LoadLibrary(_T("RICHED20.DLL"));<br />
	if (m_hRichEdit2 == NULL)	<br />
	{		<br />
		// You could not allow them to run your program at all, or work around people who don't have 2.0<br />
		AfxMessageBox("Failed to initialize rich edit 2.0", MB_OK | MB_ICONEXCLAMATION);		<br />
		return FALSE;	<br />
	} <br />
	<br />
	// Turn it on and off<br />
	CRichEditCtrl m_ctlEdit;<br />
	// -- On<br />
	if (m_hRichEdit2 != NULL)<br />
		m_ctlEdit.SendMessage(EM_AUTOURLDETECT, (WPARAM)TRUE, 0);	<br />
	// -- Off<br />
	if (m_hRichEdit2 != NULL)<br />
		m_ctlEdit.SendMessage(EM_AUTOURLDETECT, (WPARAM)FALSE, 0);<br />
	<br />
	<br />
	// Don't forget to clean up<br />
	if (m_hRichEdit2 != NULL)<br />
	{<br />
		::FreeLibrary(m_hRichEdit2);<br />
	}	<br />
<br />

DUH!!! I forgot to tell you to subclass it. There are other ways to do this, but this is the easiest in my opinion.

BOOL CMyRichEdit::PreCreateWindow(CREATESTRUCT& cs)
{
// Make sure Rich Edit 2
cs.lpszClass = "RICHEDIT20A";

return CMyRichEdit::PreCreateWindow(cs);
}

See if that completes it, sorry about that.

Hello again dear Matthew,
Sorry for delay ...

I add this code, too but it doesn't work Cry | :((

BOOL CMyRichEdit::PreCreateWindow(CREATESTRUCT& cs)
{
// Make sure Rich Edit 2
cs.lpszClass = "RICHEDIT20A";

return CMyRichEdit::PreCreateWindow(cs);
}

What's wrong ?
Can you send your project for me ?

Unfortunately my project is a product, so I really can't send that to you. That is really all that I did to implement it, don't know how you are doing it exactly.... but if you want to email me your rich edit class I can compare it to mine.... I looked at my code last night after the post... and that is really all I had. But send me some code and I can compare it.

I sent you the fixed project, you never loaded the DLL, which is needed.
