list control problem

hello
I am trying to make a list control , so that it will display both name and
number when i enter them.

1) how do i delete an item from the list control
    ie
void CSpeedDial::OnSpeedDel()
{
//
}

2)how do i move an item up or down in the list contol using "up buttom" and
"down buttom" i have created
ie
void CSpeedDial::OnSpeedUp()
{
}

and
void CSpeedDial::OnSpeedDown()
{
}

3)how do i make the "add buttom" disable when i have 8 items in the list
control.

this is what I have done so far:

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

 CRect rect;
 m_speedList.GetClientRect(&rect);
 m_speedList.InsertColumn(0,_T("Name"),LVCFMT_LEFT,rect.Width()/2,0);
 m_speedList.InsertColumn(1,_T("Number"),LVCFMT_LEFT,rect.Width()/2,0);

 m_speedList.SetImageList(&imList, LVSIL_SMALL);
 for (int i=0;i< m_speedArray.GetSize();i++)
 {
  m_speedList.InsertItem(i,m_speedArray.GetAt(i));
 }

 // TODO: Add extra initialization here

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

void CSpeedDial::OnSpeedAdd()
{
 // TODO: Add your control notification handler code here
 CString AliasName,AliasNumber;
 m_speedName.GetWindowText(AliasName);
 m_speedNumber.GetWindowText(AliasNumber);
 AliasName.TrimRight();
 AliasName.TrimLeft();
 AliasNumber.TrimLeft();
 AliasNumber.TrimRight();
 if(AliasName.FindOneOf("=|")>=0) return;

 int nIndex = m_speedList.InsertItem(m_speedList.GetItemCount(),AliasName);
 m_speedList.SetItemText(nIndex,1,AliasNumber);

 m_speedName.SetWindowText(_T(""));
 m_speedNumber.SetWindowText(_T(""));

}

thanks for you help
