I'm trying to apply a tooltip to a toolstripbutton but it keeps giving me this error:
Operator '==' cannot be applied to operands of type 'System.Windows.Forms.Control' and 'System.Windows.Forms.ToolStripButton'
Any clue on how to solve this?
UPDATE:
private void toolTip1_Popup(object sender, PopupEventArgs e)
{
    if (e.AssociatedControl == tBtn1)
    {
        using (Font f = new Font("Tahoma", 9))
        {
            e.ToolTipSize = TextRenderer.MeasureText(
                toolTip1.GetToolTip(e.AssociatedControl), f);
        }
    }
}
