CHARFORMAT and EM_SETCHARFORMAT

Hi. I am trying to underline a certain word in a rich edit control, located in a Dialog Box. I understand that I should select the word by sending the EM_SETSEL message, and then format it with the EM_SETCHARFORMAT message using a CHARFORMAT structure. Whenever I call the SendMessage function for the EM_SETCHARFORMAT message, it fails and returns 0. I have searched the board and msdn and have failed to discern the problem. Any help is appreciated. Thank you in advance.

Code:

	//format
	CHARFORMAT cf;
	ZeroMemory(&cf,sizeof(cf));
    cf.cbSize=sizeof(cf);
	lstrcpy(cf.szFaceName,"Arial");
/*	cf.bCharSet=ANSI_CHARSET;
	cf.bPitchAndFamily=FF_ROMAN;*/
	cf.dwMask=CFM_UNDERLINE;
    cf.dwEffects=CFE_UNDERLINE;
   
	SetFocus(GetDlgItem(hdlg,IDC_BIBLIO2));
	SendMessage(GetDlgItem(hdlg,IDC_BIBLIO2),EM_SETSEL,(WPARAM)pos1,(LPARAM)pos2);
	if(SendMessage(GetDlgItem(hdlg,IDC_BIBLIO2),EM_SETCHARFORMAT,(WPARAM)SCF_WORD|SCF_SELECTION,(LPARAM)(CHARFORMAT FAR *)&cf)==0)
		MessageBox(NULL,"ERROR","ERROR",MB_OK);

Never mind. . . probelm solved. Stupid error.
