Output formatted text to Screen - c++

Question

I have a vector that stores pairs. Each pair contains a CString and a bool.
If the CString is meant to be underlined then bool is true, else it is false.
I want to output the text in the vector to the screen making sure that text is underlined in the correct places.
So far I have the following code:
void CEmergenceView::AppendText( CString msg ) {
int nBegin;
CRichEditCtrl &rec = GetRichEditCtrl();
nBegin = rec.GetTextLength();
rec.SetSel(nBegin, nBegin); // Select last character
rec.ReplaceSel(msg); // Append, move cursor to end of text
rec.SetSel(-1,0); // Remove Black selection bars
nBegin = rec.GetTextLength(); // Get New Length
rec.SetSel(nBegin,nBegin); // Cursor to End of new text
// Fix annoying "do you want to save your changes?" when program exits
GetDocument()->SetModifiedFlag(FALSE); // -Optional- (sometimes you want this)
}
int nEnd = 0;
// loop through start of text to end of text
for(int k = 0; k < groups.size(); k++) {
rEditCtrl.SetSel(nEnd, nEnd);
rEditCtrl.GetSelectionCharFormat(cf);
if(groups.at(k).second) {
if(!cf.dwEffects & !CFE_UNDERLINE) {
CRichEditView::OnCharUnderline();
}
}
else if(!groups.at(k).second) {
if(cf.dwEffects & CFE_UNDERLINE) {
CRichEditView::OnCharUnderline();
}
}
AppendText(groups.at(k).first);
nEnd = nEnd + (groups.at(k).first.GetLength());
}
However, this is not underlining at all....Can anyone tell me what I'm doing wrong?? Thanks!

Answer 1

I think you should implement the OnCharUnderline
Try to call yours own function instead of the default one:
You can get it from here:
void CMyRichEditView::OnCharUnderline ()
{
CHARFORMAT2 cf;
cf = GetCharFormatSelection();
if (!(cf.dwMask & CFM_UNDERLINE) || !(cf.dwEffects & CFE_UNDERLINE))
cf.dwEffects = CFE_UNDERLINE;
else
cf.dwEffects = 0;
cf.dwMask = CFM_UNDERLINE;
SetCharFormat(cf);
}
