Vector.Erase?

Hi, all:

I am trying to migrate a VC++ 6.0 code into VS 2005. it is the code of
Typing Aid ComboBox comes from

http://www.codeguru.com/cpp/controls/combobox/article.php/c4951/.

Looks like std::vector does not support erase items like array
anymore.
m_vSections.erase(&m_vSections[i--]);

So I tried to change it using iterator, but the result does not acting
the same. Can somebody take a look on what I am doing wrong?

Also, if you guys have a better reference for a Typing Aid comboBox
(show muitiple Col in the drop down, when user type, looking for the
first match item in the dropdown. please guide me or show me the
hyperlinks.

Thanks in advance.
