New process/exe from a switch?
I am new at this, but I've been following along with this video: https://www.youtube.com/watch?v=0Wcn-ZK9mi4
I have an OK understanding of what is going on in the code below and marked where I believe I should launch the app. The problem is, I am not sure what to use. I have read that I can use Sytem.Diagnostics.Process.Start but that doesn't seem to work; Can anyone help a newbie out?
I realize I am in over my head but I am having fun and learning as I go; any help is greatly appreciated!
Code:
sealed partial class App : Application
{
/// <summary>
/// Initializes the singleton application object. This is the first line of authored code
/// executed, and as such is the logical equivalent of main() or WinMain().
/// </summary>
public App()
{
this.InitializeComponent();
this.Suspending += OnSuspending;
}
/// <summary>
/// Invoked when the application is launched normally by the end user. Other entry points
/// will be used such as when the application is launched to open a specific file.
/// </summary>
/// <param name="e">Details about the launch request and process.</param>
protected async override void OnLaunched(LaunchActivatedEventArgs e)
{
#if DEBUG
if (System.Diagnostics.Debugger.IsAttached)
{
this.DebugSettings.EnableFrameRateCounter = true;
}
#endif
Frame rootFrame = Window.Current.Content as Frame;
// Do not repeat app initialization when the Window already has content,
// just ensure that the window is active
if (rootFrame == null)
{
// Create a Frame to act as the navigation context and navigate to the first page
rootFrame = new Frame();
rootFrame.NavigationFailed += OnNavigationFailed;
if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
{
//TODO: Load state from previously suspended application
}
// Place the frame in the current Window
Window.Current.Content = rootFrame;
}
if (e.PrelaunchActivated == false)
{
if (rootFrame.Content == null)
{
// When the navigation stack isn't restored navigate to the first page,
// configuring the new page by passing required information as a navigation
// parameter
rootFrame.Navigate(typeof(MainPage), e.Arguments);
}
// Ensure the current window is active
Window.Current.Activate();
try
{
StorageFile vcd = await Package.Current.InstalledLocation.GetFileAsync(@"CustomVoiceCommandDefinitions.xml");
await VoiceCommandDefinitionManager.InstallCommandDefinitionsFromStorageFileAsync(vcd);
}
catch(Exception ex)
{
Debug.Write("Failed to register custom voice commands because: " + ex.Message);
}
}
}
protected async override void OnActivated(IActivatedEventArgs args)
{
base.OnActivated(args);
if(args.Kind == ActivationKind.VoiceCommand)
{
VoiceCommandActivatedEventArgs cmd = args as VoiceCommandActivatedEventArgs;
SpeechRecognitionResult result = cmd.Result;
string commandName = result.RulePath[0];
switch (commandName)
{
case "VoiceInputHere":
//app launch here
break;
default:
Debug.WriteLine("Couldn't find command name");
break;
}
await;
}
}

Re: New process/exe from a switch?
Process.Start is what to use, but you say it didn't work for you? Post the code that you tried so we can see where it went wrong.
