Answer 1

That's because you are removing the controls from the same list you are iterating. Try something like this

List listControls = flowLayoutPanel.Controls.ToList();

foreach (Control control in listControls)
{
    flowLayoutPanel.Controls.Remove(control);
    control.Dispose();
}

Maybe not like that, but you get the idea. Get them in a list, then remove them.
