RichEdit Control not show text

[olivthill2]

Please, use [code] and [/code] tags around your lines of code. They will show nicely like this:

m_rich.SetWindowText (cadena);

Where does m_rich come from?

Anyway, I have used successfully Rich Edit Controls but I have done it in C, not in C++. I show you what I do when I want to insert a character:

/* =================================================================
   Write a character in the RTF control
   ================================================================= */
int RTFEDIT_putc(char c, COLORREF col, int h, int x)
{
   CHARFORMAT cf; char buf[2]; // HDC hdc;

   Edit_Enable(hRTF, FALSE);

   ZeroMemory(&cf, sizeof(CHARFORMAT));
   cf.cbSize = sizeof(CHARFORMAT);
   cf.dwMask = CFM_BOLD | CFM_COLOR | CFM_ITALIC |
                          CFM_SIZE | CFM_UNDERLINE;
   cf.dwEffects = 0;
   if (h > 0)
      cf.yHeight = h;
   else
      cf.yHeight = 160;
   cf.yOffset = 0;
   if (col > 0)
      cf.crTextColor = col;
   else
      cf.crTextColor = RGB(0,0,0);

   Edit_SetSel(hRTF, x, x+1);
   buf[0] = c; buf[1] = '\0';
   SendMessage(hRTF, EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf);
   Edit_ReplaceSel(hRTF, buf);
   Edit_SetSel(hRTF, 0, 0);

   Edit_Enable(hRTF, TRUE);

   return TRUE;
}
