Add formatting to Richtext box

I have a rich edit control and I want to add formatted text in it but it doesn't work:

const char* str="{\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard\
This is some {\b bold} text.\par\
}";
    LoadLibrary("riched32.dll");

    HWND hEdit= CreateWindowEx(WS_EX_CLIENTEDGE, RICHEDIT_CLASS, str,
        WS_CHILD | WS_VISIBLE | WS_VSCROLL | ES_MULTILINE | ES_AUTOVSCROLL 
| ES_READONLY, 0, 0, 100, 100,
        hwnd, (HMENU) IDC_MAIN_EDIT, GetModuleHandle(NULL), NULL);

I know I can add formatting using PARAFORMAT and CHARFORMAT and the sending a message to the control like this:

PARAFORMAT pf;
CHARFORMAT cf;

memset( &cf, 0, sizeof cf );
cf.cbSize = sizeof cf;
cf.dwMask = CFM_BOLD;
cf.dwEffects = CFE_BOLD;
SendMessage( hEdit, EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM) &cf);
SendMessage( hEdit, EM_REPLACESEL, FALSE, (LPARAM) "bold ");

But how can I make the first one work or if there is no way, is there a simpler method than the second? Thanks in advance.

Rich edit controls won't accept RTF in the way you're trying in the first code block. To get RTF into the control you need to use the ES_STREAMIN message.
