What's wrong with this code?

Is there anything wrong with this code?

namespace RotnetSudoku
{
public partial class splash : Form
{
public splash()
{
InitializeComponent();
fclsStartScreen frmStartscreen = new fclsStartScreen();
frmStartscreen.Show();
this.Visible = false;
}
}
}

Apart from the indentation?

When i run it ithe splash form doesn't close...Also, if i change

this.Visible= false;


to

this.close();


, i get this error:

System.ObjectDisposedException was unhandled
Message="Cannot access a disposed object.\r\nObject name: 'splash'."
Source="System.Windows.Forms"

To make it invisible use this code:

this.Hide();

BUT if you are hiding your main form, then you will have to use Application.Exit(); when you want to shut down the application. Otherwise it will still run and cause problems. If it's not the main form of your application (by that I mean Form1), then use this.Close(); to just simply get rid of the form.

Hope this helps
