Answer 1

If you don't want the user messing with the control, disable it. On another level however, if it's critical the user NOT use the control... maybe you should change the control.

ComboBox.Enabled = false;

Answer 2

combobox.MouseWheel += new MouseEventHandler(combobox_MouseWheel);

void combobox_MouseWheel(object sender, MouseEventArgs e)
{
    ((HandledMouseEventArgs)e).Handled = true;
}
