以下给出源代码： (注：hide为窗体名称)
代码如下：

private void hide_Load(object sender, EventArgs e)
{
System.Windows.Forms.Timer StopRectTimer = new System.Windows.Forms.Timer();
StopRectTimer.Tick += new EventHandler(timer1_Tick);
StopRectTimer.Interval = 100;

}

{

{
switch (this.StopAanhor)
{
case AnchorStyles.Top:
this.Location = new Point(this.Location.X, 0);
break;

this.Location = new Point(0, this.Location.Y);
break;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);

}
}
else
