The number of active processing cores available on the computer. (Since iOS 9.0) Properties ActiveProcessorCount As Integer Closeįires on macOS when the control placed on a window layout is about to close. Events Openįires when the instance initialized. In other cases (iOS or usage as a property), you should call the Unregister() method when you want to clear the memory fully. The class will remove these modifications once the parent window closes.

On macOS, when using CSProcessInfo like a control dropped below a window layout, you need not worry. Important: CSProcessinfo installs a few notifications on itself, using NSNotificationCenter. UsageĮither drop an instance of the class on your window or iOSView or install it as a property: Dim CSP as New CSProcessInfo No serial included, no home phoning, no spying. Again, background threads are not officially supported by Xojo and could in theory stop working at some time. This class is provided as-is, and it is important that you make sure you don’t try any not-allowed features with PerformExpiringActivity or your app will crash. You can get the unencoded Xojo code for 30 € the same way. You can get a lifetime license (meaning a version without the nag screen and updated if anything should change in the future) by sending a PayPal payment of 10 € to containing the message ProcessInfo. How to get itĪn encrypted demo version (unlimited but with a nag message box that appears in builds) is available here. Important! This class needs Joe Ranieri’s ObjC Blocks plugin for macOS which can be found here. Where not noted otherwise, the properties and methods are available on both systems. Also there are some limitations on what can be done in these threads. On iOS, it is even possible to invoke real preemptive threads, but please be aware these need some kind of preparation and are not officially supported by Xojo. Disallowing these functions gives you the means to finish longer lasting processes without having to fear that these could be interrupted by user or system requests. It is useful for requesting some system information and to avoid sleep or sudden termination, a feature the system uses to close down apps more quickly.

Deutsche Leser bitte nicht verwirren lassen: Erklärung folgt in Kürze!ĬSProcessInfo is a standalone class containing NSProcessInfo, usable on macOS and iOs as well.
