The DoSplash should probably call <code>sp.Show()</code> instead of <code>sp.ShowDialog()</code>

But calling Sleep(x000) form your main thread to show a splash screen isn't very efficient, and Thread.Abort() should be reserved for better use too.

A better approach is to close your SplashForm with a Timer and set a minimum delay. On startup you can Show() and Update() the SplahForm and continue to load stuff. The timer event won't fire until the MainForm is finished initializing and enters the EventLoop. No threads needed, and the MainForm doesn't have to be involved either.

Just to give you the main ingredients of a MessageLoop driven SplashForm:

<pre><code>public partial class SplashForm : Form
{
 // default stuff

 public static void Splash()
 {
 var s = new SplashForm();
 s.Show();
 s.Update();// force paint
 }

 private void SplashForm_Load(object sender, EventArgs e)
 {
 Timer t = new Timer();
 t.Interval = 1; // wait for EventLoop
 t.Tick += GoAway;
 t.Enabled = true;
 }

 private void GoAway(object sender, EventArgs e)
 {
 this.Close();
 }
}
</code></pre>

and then, in Program.cs, 

<pre><code>Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
SplashForm.Splash();
Application.Run(new MainForm());
</code></pre>

That's an ugly implementation. You should check out <a href="https://stackoverflow.com/questions/48916/multi-threaded-splash-screen-in-c">this SO thread</a>.

First of all, the way the splash screen on that page is done, using <a href="http://msdn.microsoft.com/en-us/library/system.threading.thread.abort(VS.71%29.aspx" rel="nofollow noreferrer">Thread.Abort</a>, is not the right way to do things.

Never call <a href="http://msdn.microsoft.com/en-us/library/system.threading.thread.abort(VS.71%29.aspx" rel="nofollow noreferrer">Thread.Abort</a>, unless you're in the process of shutting down the <a href="http://msdn.microsoft.com/en-us/library/system.appdomain.aspx" rel="nofollow noreferrer">AppDomain</a> the thread lives in.

Let me reiterate that for emphasis. The only time you should call <a href="http://msdn.microsoft.com/en-us/library/system.threading.thread.abort(VS.71%29.aspx" rel="nofollow noreferrer">Thread.Abort</a> is when you know enough about <a href="http://msdn.microsoft.com/en-us/library/system.threading.thread.abort(VS.71%29.aspx" rel="nofollow noreferrer">Thread.Abort</a> and how it behaves to know that you should never call it.

Take a look at this other question on StackOverflow: <a href="https://stackoverflow.com/questions/48916/multi-threaded-splash-screen-in-c">Multi-Threaded splash screen in c#?</a>.

<hr>

If you want to keep your existing solution, a possible better way would be to drop a timer into the splash screen form, set its timer to the time you want the splash screen to stay on screen, and call <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.form.close.aspx" rel="nofollow noreferrer">Close</a> in its Tick event handler.

In the same venue, I would simply fire off that original thread, and remove the other lines.

In other words, from the first code block on that page, I would keep these two lines:

<pre><code>Thread th = new Thread(new ThreadStart(DoSplash));
th.Start();
</code></pre>

Couple that with that timer on the form that makes the form self-closing, and you're in way better shape than trying to get to grips with Thread.Abort.

Which you should not call.

I'm using a Splash Screen from <a href="http://www.codersource.net/csharp_splash_screen.aspx" rel="nofollow noreferrer">Here</a>. I love how simple it is. But the problem with it is that the splash screen doesn't go away until I click on it. When run within the IDE it works fine. Any ideas? I'd attach the code here but its not inserting properly for some reason.

<pre><code>private System.Windows.Forms.Timer timer1;
//private Splash sp=null;

public Form1()
{
 InitializeComponent();

 Thread th = new Thread(new ThreadStart(DoSplash));
 //th.ApartmentState = ApartmentState.STA;
 //th.IsBackground=true;
 th.Start();
 Thread.Sleep(3000);
 th.Abort();
 Thread.Sleep(1000);
}

private void DoSplash()
{
 Splash sp = new Splash();
 sp.ShowDialog();
}

private void timer1_Tick(object sender, System.EventArgs e)
{
// sp.Close();
}
</code></pre>

Splash Screen that doesn't go away
