Private Sub RectangleShape1_MouseEnter(
  ) Handles RectangleShape1.MouseEnter

    ToolStripStatusLabel1.Text = "The mouse has entered the shape."
End Sub

Private Sub RectangleShape1_MouseHover(
  ) Handles RectangleShape1.MouseHover

    ToolStripStatusLabel1.Text = "The mouse is paused over the shape."
End Sub

Private Sub RectangleShape1_MouseLeave(
  ) Handles RectangleShape1.MouseLeave

    ToolStripStatusLabel1.Text = "The mouse has left the shape."
End Sub

Private Sub RectangleShape1_MouseMove(
  ) Handles RectangleShape1.MouseMove

    ToolStripStatusLabel1.Text = "The mouse is over the shape."
End Sub
private void rectangleShape1_MouseEnter(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse has entered the shape.";
}

private void rectangleShape1_MouseHover(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse is paused over the shape.";
}

private void rectangleShape1_MouseLeave(object sender, System.EventArgs e)
{
    toolStripStatusLabel1.Text = "The mouse has left the shape.";
