Restarting a C# application

[Elroacho]

Hi,

I'm trying to write some code that will closed down and restart my application once it have completed a code download using the Updater application block (InProcess method scenario). I've tried the following:

//CheckUpdate is my class for checking and downloading updates. 
//Returns true if an update is waiting to be applied
if (CheckUpdates.RestartRequired == true)
   {
	Application.Exit();
    System.Diagnostics.Process.Start(Application.ExecutablePath);
   }

This performs the shutdown and restart but doesn't activate the PostActivationExitActivationProccess in between.

Any ideas welcomed!

Cheers,
Kevin

Why not open your app in a new thread which is contained within another thread?

when that thread exits, launch another thread if necessary.

How would I implement this?

Would this get around the PostActivationExitActivationProccess not starting?

Why restart the app? Why not just back to the starting point?

You can have a class called clsStart with a public variable called Restart. You can then set your project to start in clsStart's Main method, like so:

	public class clsStart
	{
		public static bool Restart = false;
		public clsStart(){}
		
		public static void Main()
        {
			Restart = false;
			Form1 f1 = new Form1();
			f1.ShowDialog();
			f1.Dispose();
			f1 = null;

			if (Restart == true)
			{
				Main();
			}
		}
	}
}

Then, when you need a restart, you can do something like:
clsStart.Restart = true
this.Close();
//Other logic to close dispose of other lingering objects

I can't see how this would shut down the allpication so the update process can kick in. The application process (as seen in task manager) need to completely close before the PostActivationExitActivationProccess can run which is what starts the deplyoment of the new updated code.

OK, I see now. I've not used that ms update application thing. Have you seen this page?

From what I can gather, a shell apps starts a process of your real application

Cheers, I will have a read through that when I get the chance.

Thanks,
