.NET Compact Framework
The Compact Framework provides the capability to start a separate process from your code, and stop it but it doesn’t give you more detailed information about what is running and what components are in use. Windows CE includes the optional ToolHelp component (present in all Windows Mobile versions). The InTheHand.Diagnostics namespace includes a number of classes for working with ToolHelp in a way which matches the full .NET Framework. The ProcessHelper class includes the GetProcesses() static method to return all running processes on the device. Extension methods GetModules() and GetThreads() return ProcessModule and ProcessThread collections for a specific Process.
ProcessModule exposes name, size and version information for an individual module. ProcessThread exposes id, priority and elapsed processor time.
Another way you might want to interrogate a process is to determine the memory usage. For your own process we’ve followed the Windows Phone model and so InTheHand.Phone.Info.DeviceStatus.ApplicationCurrentMemoryUsage
provides you this useful figure as a strongly-typed property. It is also accessible from the GetValue method as you would on Windows Phone.
Other than the built in set of tasks you can’t start any other applications or tell if they are running. You do have access to memory statistics though which are accessible from the Microsoft.Phone.Info.DeviceExtendedProperties class. A limitation here is that if you use this method to get the memory statistics your app will automatically get marked as requiring the ID_CAP_IDENTITY_DEVICE capability which it doesn’t actually need for these properties. We built a helper class for two reasons – firstly to remove this requirement and secondly to provide strongly-typed properties as an alternative to the GetValue implementation. On Windows Phone therefore you can use:-
