Underlining in RichEdit box

I have a form that the user fills out and, upon completion, the form is printed in a RichEdit box in a set format (as a works cited entry). I do this by attaching the variable m_entry to the RichEdit box and once the user clicks a button, the variable m_entry is filled using a simple (eg. m_entry = m_field1 + ", " + m_field2) method. I would like to make one of the fields, when put into the m_entry variable, underlined. How do I do this?

I got many errors when I tried this:

1) SetSel is not a member of CString
2) ReplaceSel is not a member of CString
3) GetSel is not a member of CString
4) GetSelectionCharFormat is not a member of CString
5) GetTextLength is not a member of CString

Do I need to add a library file or something? I'm a beginner so I'd appreciate if someone could give me further instructions. Thanks a lot.

Your m_richEdit member is a CString bound by value, not a control bound by reference.

void CYourDlg::OnOK()
{
// get first string
CWnd* pEditOne = GetDlgItem(IDC_EDIT1);
ASSERT(pEditOne != NULL);
CString strOne;
pEditOne->GetWindowText(strOne);

// get second string
CWnd* pEditTwo = GetDlgItem(IDC_EDIT2);
ASSERT(pEditTwo != NULL);
CString strTwo;
pEditTwo->GetWindowText(strTwo);

// get edit control itself
CRichEditCtrl* pRich = (CRichEditCtrl*) GetDlgItem(IDC_RICHEDIT1);
ASSERT(pRich != NULL)

// set at the end of the control
int n = pRich->GetTextLength();
pRich->SetSel(n+1, n+1);

// build a string to add
CString strAdd;
strAdd = strOne + " to " + strTwo + "\r\n";

// add it to the control
pRich->ReplaceSel(strAdd, FALSE);

// get formatting of string
CHARRANGE range;
pRich->GetSel(range);

// select first part of the string we just added
range.cpMin -= strAdd.GetLength();
range.cpMax = range.cpMin + strOne.GetLength();
pRich->SetSel(range);

// get the format of that selection
CHARFORMAT format;
format.cbSize = sizeof(format);
pRich->GetSelectionCharFormat(format);

// modify format to include underlining
format.dwMask |= CFM_UNDERLINE;
format.dwEffects |= CFE_UNDERLINE;

// set formatting back
pRich->SetSelectionCharFormat(format);

// select the end again
n = pRich->GetTextLength();
pRich->.SetSel(n+1, n+1);
}

You should have been able to diagnose and correct the problem by yourself. To get a better understanding of data exchange in dialog boxes and the difference between exchanging the control reference and exchanging the data itself, grab a good MFC book or reread the documentation about DDX.
