Carriage return in CRichEditCtrl

In MSVC 4.2, I have an multiline edit box of type CRichEditCtrl, and every line I insert goes to the first line. I tried to add EOL, \n, \r, \n\r, \r\n and nothing helps. Any hint?

        CRichEditCtrl   m_log;
        ...
        sprintf(log_msg, "Current script file: %s\r\n", scrname);
        m_log.SetWindowText(log_msg);

        sprintf(log_msg, "Current message file: %s\r\n", msgname);
        m_log.SetWindowText(log_msg);

That's normal you couldn't see more than one line with the code you give there!

First you have to know that calling SetWindowText will Replace ALL THE TEXT inside your CRichEditCtrl by the one you give there!

So if you do those 2 calls:
m_log.SetWindowText("First try");
//there you have the text "First try" in your CRichEdiCtrl
m_log.SetWindowText("Second try");
//there you have the text "Second try" in your CRichEdiCtrl
//what you have done there, is to replace "First try"
//by "Second Try"

In fact you got two ways to do what you wanna do!

1)  Use a Temporary Text to store all before putting it in the CRichEditCtrl


CRichEditCtrl m_log;
...
CString strWholeText;
sprintf(log_msg, "Current script file: %s\r\n", scrname);
strWholeText += log_msg;
sprintf(log_msg, "Current message file: %s\r\n", msgname);
strWholeText += log_msg;
m_log.SetWindowTextstrWholeText);


2) Add it by replacing the Selection, line after line

void AddLine(CString strLine)
{
//First retrieve the Whole Text selection value

//Remind Old Selection to put it back later
CHARRANGE oldCharRange;
m_log.GetSel(oldCharRange);
//Select All then
m_log.SetSel(0,-1);
long nUnusedStart, nUsefullEnd;
m_log.GetSel(nUnusedStart, nUsefullEnd);
//Select empty selection at end
m_log.SetSel(nUsefullEnd, nUsefullEnd);
//ReplaceSelection by the wanted line
m_log.ReplaceSel(strline);

//Put back Old Selection
m_log.SetSel(oldCharRange);
}
