It is very easy to do this but needs a bit of imagination and skill. Here is the code snippet that does it all.

private void button1_Click(object sender, EventArgs e)

{

if (minsys.Checked == true)

{

this.Visible = false;

}

this.WindowState = FormWindowState.Minimized;
}

This is the event handler of the minimize button.

Check the application and see how it works.
