Can u please also tell me how to highlight a particular word in the Rich edit box.

CHARFORMAT cf;<br />
memset(&cf, 0, sizeof(CHARFORMAT));<br />
cf.cbSize = sizeof(CHARFORMAT);<br />
cf.dwMask = CFM_BOLD;<br />
cf.dwEffects = CFE_BOLD;<br />
<br />
// **** pseudo-code ****<br />
for (int i = 0; i < size of your word list; i++)<br />
{<br />
    m_FCONT.SetSel(word_position[i], word_length[i]);<br />
    m_FCONT.SetSelectionCharFormat(cf);<br />
}<br />

We need to overwrite it (at any cost) thats why we not require that messagebox. becuase it will stop at the message box and the user must be there to click on Yes or No ,
In my application user interaction is not required so in absence of user the application will wait at the message to get response from user.

Since there is not user interaction and we also need to over write it always so we not require this message box
