Hi,

System.Threading.Thread mthread = new System.Threading.Thread(() =>
            {
                bar = new ProgressBar();
                bar.ShowInTaskbar = false;
                bar.SleepTime = System.Convert.ToInt32(2000);
                bar.ShowDialog();
            }
            );
            mthread.SetApartmentState(System.Threading.ApartmentState.STA);
            mthread.Start();
            var X= new X()
                                    {
                                        StartupEventArgs = e
                                    };

            X.Run();
            bar.Dispatcher.BeginInvoke(new System.Action(() => { bar.Close(); }));
            bar.Dispatcher.Thread.Abort();
            mthread.Abort();
            App.Current.Dispatcher.Thread.SetApartmentState(System.Threading.ApartmentState.STA);
            Application.Current.Dispatcher.BeginInvoke(new System.Action(() => { App.Current.MainWindow.Show(); }));  

Basically X is like bootstrapper.It loads the data.Now when the last line is executed , i get the foloowing error - The calling thread cannot access this object because a different thread owns it.

bar is a dialog that i am opening.I have a progress bar in that dialog.

Please help
