I'm working on creating custom Cortana commands. The commands are registered and executed using a Universal Windows Platform Application. (GitHub)
For instance, I've registered the following command
<Command Name="ShutDown">
<ListenFor>Shut down</ListenFor>
<Navigate/>
</Command>
To run this function in a UWP application
static async void ShutDown()
{
var dialog = new MessageDialog("This is where I would shut the computer down.");
await dialog.ShowAsync();
//System.Diagnostics.Process.Start("Shutdown", "-s -t 10");
}
But after setting this up I learned System.Diagnostics.Process
isn't supported in UWP.
The custom commands I want to run involve some sort of execution such as launching external programs, running other scripts, or opening websites.
It makes sense that UWP doesn't support them given that it's universal and an XBox or a phone might not be able to do these, but I was hoping there was some alternative or hacky way to accomplish this on a Windows 10 PC.
Is there a way for me to execute Process
commands or something else with similar functionality in a UWP application? It seems like even though I can get Cortana to execute my C# code, UWP doesn't support much that would be useful in this situation.
Thanks in advance.
There are - limited - ways to achieve similar behavior.
You could use LaunchUri to trigger other apps which registered for a certain URI-Scheme. This should work for your webbrowser scenario. More details here: https://msdn.microsoft.com/en-us/library/windows/apps/windows.system.launcher.launchuriasync.aspx
You could trigger another app and get results back from it using LaunchForResults. The called app has to support this. More details here: https://msdn.microsoft.com/en-us/library/windows/apps/mt269386.aspx
You could trigger App Services provided by another app. The called app has to support this. The app service will be executed in background. ( I think this is pretty cool.) More details here:http://blogs.msdn.com/b/mvpawardprogram/archive/2015/06/11/writing-windows-10-app-services-in-javascript.aspx
This is a little hacky: I'm not sure if this still works but it did work for Windows 8.1: You could create a so called "Brokered Component". This allows you to trigger everything from you app on you machine, but you won't be able to publish a brokered component into the store. This also allowed Process.Start() on Windows 8.1. It only worked for sideloaded apps. I'm not sure if it still works on Windows 10. More info here: https://msdn.microsoft.com/en-us/library/windows/apps/dn630195.aspx
Summary: Starting another app is pretty easy as long as the target app registered as app service or registered a protocol handler (Uri scheme). Starting scripts or other *.exe is impossible if option 4 doesn't work any longer.
