Multithreading problem

[thepersonof]

Hi I know multithrading is explained in several tutorials, but I can't figure out how to terminate another thread gracefully. This is my current code. In thread1 when I dispose s I get an error... I realised this would happen with sychronisation etc. What can I do? public class Loader { PNG.SplashScreen s; Form1 f; Thread first; Thread second; public Loader() { first = new Thread(new ThreadStart(thread1)); second = new Thread(new ThreadStart(thread2)); first.Start(); second.Start(); } void thread1() { f = new Form1(); s.Dispose(); f.ShowDialog(); } void thread2() { s = new PNG.SplashScreen(); s.ShowDialog(); } } cheers

You can't really terminate another thread gracefully. You either kill it ungracefully via someThread.Abort (which injects the ThreadAbortException into the thread being aborted), or you can cancel gracefully by having someThread check for some boolean cancel state over time and exiting when it hits that state.

You error most probably comes from the fact that it is only safe to alter GUI elements from within the thread they where created in. Have a look at the Invoke[^] method.
