before the dialog box is displayed.It initializes the dialog
box controls.We can override this function in our derived
dialog class. By default , it returns TRUE

Ex:-

BOOL CMyDialog::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here
m_cMyEdit.SetWindowText("My Name"); // Initialize control values
m_cMyList.ShowWindow(SW_HIDE); // Show or hide a control, etc.

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
