Hi Guffa,

Thanks for you reply, I'm getting really stuck on this.

I've been trying to do what the guy above suggested with little success, here's where I'm at right now.

<br />
Form2 loadForm;<br />
<br />
       private delegate void TestDelegate();<br />
       public Form1()<br />
       {<br />
          InitializeComponent();<br />
<br />
          Thread t = new Thread(delegate() { <br />
              this.loadForm = new Form2(); <br />
          });<br />
          t.Start();<br />
<br />
          this.BeginInvoke(new TestDelegate(Openform));<br />
<br />
          Thread.Sleep(4000); // do stuff in main thread     <br />
<br />
          this.BeginInvoke(new TestDelegate(Closeform));<br />
<br />
          t.Abort();<br />
       }<br />
<br />
        private void Openform()<br />
        {<br />
            this.loadForm.ShowDialog();<br />
        }<br />
<br />
        private void Closeform()<br />
        {<br />
            this.loadForm.Dispose();<br />
        }<br />


This isnt even compiling at moment (Error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created.), so I'm getting pretty anoyed with the whole threading thing.

How else can you close a thread without calling Abort? Can you spot where i'm screwing up here?

Im trying to:

1. Create a (non-visible) window in thread 1
2. Show a loading window in thread 2 (form 2)
3. Do some loading in thread 1
4. Close the loading window in thread 2
5. Show the window in thread 1


Thanks heaps,
