CRichEditCtrl::clear() doesn't work???

[scdong]

Hi,
I'm using the following code snippet to clear the rich edit control
when i want to refresh its content:
mRichEditCtrl.SetReadOnly(FALSE);
mRichEditCtrl.SetSel(0, -1);
mRichEditCtrl.Clear();
But it's doesn't work. What should I do? I'm using VS2008 and want to
Rich Edit 2.0 for localized language. Any ideas are welcome.

Thanks
-Jerry

It works fine when I do it!

how about:
mRichEditCtrl.SetWindowText(_T(""));

I have debugged the code, the window text actually has been set to
empty, but it doesn't refresh the UI. So when i want to outout
something in rich edit control, the new output is followed by previous
output. All I want is to clear the UI, so i can output in the start of
the client area of rich edit control.

This works for me:

m_REventDisplay.SetSel(0, -1);
m_REventDisplay.Clear();

It may be that your RichEditCtrl is inadvertently protected, i.e. has /protected (or similar, can't quite remember) RTF tag somewhere. If that's the case, you can trap an EN_PROTECTED message when the user is taking an action that would change the protected range of text. Trap this message by calling ctrl.SetEventMask(ctrl.GetEventMask() | ENM_PROTECTED); before making any calls to change the text.

When handling the EN_PROTECTED message (which is sent to the control's parent unless it's reflected back to the control), if you return FALSE, the action is permitted, despite the protected state; returning TRUE dumps the action and the computer beeps.

Hope this helps. Had me for a while.
