![]() ![]() These two types of exception should clearly be handled differently. For example, smart pointers will throw an exception if the underlying pointer is null. NET, both types of error will raise an exception.Ĭ++ too is gradually moving towards the. In C++, the former raises an exception (or returns an error code depending on the API), whilst the latter will cause the program to terminate. Whilst exceptions remove the need for lots of if-statements, they can potentially make it harder to distinguish between external error conditions at runtime that can be dealt with (connection failed, file not found, etc), and errors within the program logic that cannot (null reference, index out of range, etc). Not checking the return codes would be bad programming to say the least! In spite of this tediousness, one arguable benefit of using error codes was that it forced the developer to explicitly check for error conditions and to structure the code in such a way that these were correctly handled. This meant the code would typically include lots of if-statements that could obscure the flow of the algorithm and make it harder to maintain. However, the key problem was that you were forced to explicitly check the error code after each call in order to make sure that it had been successful before proceeding. (By the way, this still isn’t a bad idea and can be very useful in some cases). If you were being more object-oriented about it, you could return an error/status object that encapsulated all this information. It wasn’t uncommon to provide additional helper methods to return error messages, further details, etc. Each method would return an enum value or integer that indicated whether the operation had been successful or whether a particular kind of error had occurred. Before exception handling became widespread, error checking was mainly done through the use of error codes. Runtime error conditions vs program logic errorsįirst, a quick recap. In this article, we examine various issues surrounding how exceptions are handled in. The basic mechanism in most modern programming languages for catching and handling errors is through the use of exceptions. We therefore devote a great deal of development time to ensuring that the code we build is resilient and can correctly recover from many common runtime conditions. Restart service.At Sinara, we build many server-side applications that must run 24×7 and cope successfully with the myriad problems that might occur in any live production system, including network outages, disk space problems, server restarts, slow connections, etc. Stop the service and perform the install using the version downloaded. To upgrade Emby Server, download the latest version from. NOTE: Emby will not auto update while running as a service. This is important because without this, using the Shutdown button inside Emby Server will cause NSSM to automatically restart Emby Server. Then, on the exit actions tab, make sure to configure the exit action to not automatically restart: ![]() Service name: Emby Server (or other name of your choice).Startup directory: folder containing the above executable.Application path: path to EmbyServer.exe.Type "nssm install" to open the NSSM user interface.įollow this guide to create your Windows Service, but incorporate the following changes:.Open a command prompt as admin and "cd" to the folder containing NSSM.You'll need to keep NSSM in this folder in order for the service to function. Save nssm.exe to a folder of your choice.Make sure to choose the 64-bit or 32-bit version of NSSM to match the architecture of your Windows installation. To setup a Windows Service, we'll be using a program called NSSM that can turn any app into a Windows Service. Before setting up a Windows Service, you'll need to install Emby Server from the Emby website.
