thank for your help :)
I will ask with short question in next time

yes, i have read this. At this example, we call button1_Click from out test program to

private void button1_Click(object sender, System.EventArgs e)
{
textBox1.Text = "Hello World";
}

Here, sender is "Form type". I want to write sender type with "button". So how can i write?
