hi travis,
first drag the tooltip onto your form, then put the line below in your button click event. you can set some options in the tooltip.Show() method
private void button1_Click_1(object sender, EventArgs e)
{
toolTip1.Show("Tip Text Here", button1); //shows the tip on the button
toolTip1.Show("Tip Text Here", button1, 0, -50, 2500); //shows 50 pixels above the button for 2.5 seconds
}
