Application restart

General JUCE discussion
1

is there a way to restart a juce app, i have all i need to do an update of my app, the file is in place, now i need to restart, i know some win32 specific ways, but is there some universal way to do this ?

You can start it with File::launchAsProcess?

3

but can i stop the whole application and start it again ? i now i can spawn another copy of my own process and exit the original one, but that will not work as i don’t allow more then one instance of my app.

i’m talking about how any application restarts itself after an update.

I had written this code few months back and it had worked then but for some reason i don’t use it, it’s in Carbon so it would work on Macintosh.

you can use this to kill the application

bool 
KillApplication (const char* ApplicationName) // application name without extension(without .app) 
{

	OSErr err = 0, otherErr  = 0;
	ProcessSerialNumber psn ;
	psn.highLongOfPSN    =    0;
	psn.lowLongOfPSN    =    kNoProcess;
	err = GetNextProcess(&psn);
	do
	{
		CFStringRef name;
		otherErr = CopyProcessName(&psn, &name);
		if(otherErr != 0)
			return -1;

		CFStringRef processName = CFStringCreateWithCString(NULL, ApplicationName, NULL);    ;

		CFComparisonResult result = CFStringCompare(processName, name, 0);
		if(result == 0)
		{
			KillProcess (&psn);
			break;
		}
		err = GetNextProcess(&psn);       
	}while(err == 0);
	return false;

}

and then call " File::launchAsProcess"

i mean something like this: http://msdn.microsoft.com/en-us/library/system.windows.forms.application.restart.aspx

modify your code so that you allow a second instance IF there is a specific command line option, and the second instance tells the previous instance to exit.
