You must add a reference to assembly 'Accessibility, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

private void toolTip1_Popup(object sender, PopupEventArgs e)

You don't need to reference the AccessibleObject. All you need is get the name of the AssociatedControl, like so:

private void toolTip1_Popup(object sender, PopupEventArgs e)
{
    string st = e.AssociatedControl.Name;
}

As for your subquestion, to set the tooltip text dinamically you could try something like this:

        private bool recursing;
        private void toolTip1_Popup(object sender, PopupEventArgs e)
        {
            Control c = e.AssociatedControl as Control;
            if (c != null)
            {
                if (!recursing)
                {
                    recursing = true;
                    toolTip1.SetToolTip(c, "totototo");
                    recursing = false;
                }
            }
        }

Note that we have to use a flag because calling SetToolTip will cause the PopUp event to be fired again

From MSDN 

`To get or set the AccessibilityObject property, you must add a reference to the 
 Accessibility assembly installed with the .NET Framework`

So you just need to add this reference using the project references.

Of course the PopupEventArgs contains the control for which the tooltip is drawn and thus you could simply use e.AssociatedControl.Name
