No Checks i CheckBox

Well, I was trying to add a CheckBox to one of my programs. The following Message Handler was added.

Code:

---

void CCheck2Dlg::OnBnClickedCheck1()
{
        // TODO: Add your control notification handler code here
        m_text += "Check Box 1 Clicked";
  if (m_Check2 == true)
          m_text = m_text + "Check Box 2 Clicked";
  if (m_Check3 == true)
          m_text = m_text + "Check Box 3 Clicked";

        UpdateData (false);
}

---

Now, although Clicking on the CheckBoxes does what it is supposed to do, I donot see the CHECKS !!!
Why is this happening, and what do I do to restore normalcy.

Interesting. Call UpdateData(true) at the beginning of the function.
