• What is the correct way to create a single instance application?

  - by Nidonocu

  Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

• Is it possible to profile CPU / memory inside an Adobe AIR application?

  - by dain

  Couldn`t find any ActionScript native APIs even in the beta documentation, am I right supposing that this means the only way to measure CPU / memory consumption is by cooking up a custom native solution, hooking it up with AIR and making it work on each targeted platform? Basically the aim is to be able to have this information available inside AIR and not having to use an external application for profiling, not even Flex / Flash builder.

• Is there a way to add detailed remote crash reporting to a Flex Air application?

  - by keyboardsamurai

  I will be releasing my Air/Flex application soon, but I am pretty sure there are a couple of bugs that may pop up on the various platforms that Air is available for. So I was wondering if there is a way to implement a mechanism, that would send an error report, logging where the error happened, to a remote server each time an app crashes? This way I might catch errors that otherwise would go unnoticed.
