Could not reach Cloud Firestore backend. Connection failed 1 times. Most recent error: FirebaseError: [code=unknown]: Fetching auth token failed: getToken aborted

 Esto ocurre cuando se guarda el proyecto en Visual Code (lo cual vuelve a recargar todo) y despues se intenta hacer el login.

Es como si quisiera usar el token viejo para autenticarse.

La solucion, borrar los datos de navegacion (Ctrl+Shift+Supr)

Y luego darle Ctrl-P a la página.

Scroll no funciona en android con Hammer y evento (press)

  </ion-fab>

</ion-content>

 al utilizar (press), deja de andar el scroll en la lista

para solucionarlo,

en app.module.ts, poner en false pinch y rotate:

export class CustomHammerConfig extends HammerGestureConfig {

  overrides = {

      'press': { time: 1000 },  //set press delay for 1 second

      'pinch': { enable: false },

      'rotate': { enable: false }

  }

Can't bind to 'ngIf' since it isn't a known property of 'div'

 Si al crear un componente da este error,

hay que agregar el componente en app.module.ts, en el array declarations: ej, si el componente se llama PopoverEdicionReclamoComponent:

@NgModule({

  declarations: [AppComponent, PopoverEdicionReclamoComponent],

BC30451 'scripts' is not declared. it may be inaccessible due to its protection level

agregar en web.config, dentro

GitHub - Subir proyectos

Crear el repositorio en github.com (ej, nombre: gastos)

cd <path fuente>
git init
          git add .                     //agrega todos los archivos
          gitt add -all (o -a)     //agrega los archivos nuevos solamente y los que tuvieron cambios

git commit -m "agrego archivos"

//solo la 1ra vez:
git remote add origin https://github.com/cmrusso/gastos.git
git push origin master

//todas las siguientes veces
git push


(si hay problemas, git push --force origin master)


Para actualizar cambios

git commit -m "descripcion del cambio"
git push origin master

ClickOnce - ejecutar como administrador

Si se armó un setup con ClickOnce, no es posible -por diseño- ejecutarlo como administrador.

Para solucionarlo, agregar esto en el inicio de la aplicación.

Lo que hace basicamente es arrancar un nuevo proceso como administrador, y matar al actual.

private bool IsRunAsAdministrator()
{
var wi = WindowsIdentity.GetCurrent();
var wp = new WindowsPrincipal(wi);

return wp.IsInRole(WindowsBuiltInRole.Administrator);
}

private void Application_Startup(object sender, StartupEventArgs e)
{
if (!IsRunAsAdministrator())
{
    // It is not possible to launch a ClickOnce app as administrator directly, so instead we launch the
    // app as administrator in a new process.
    var processInfo = new ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase);

    // The following properties run the new process as administrator
    processInfo.UseShellExecute = true;
    processInfo.Verb = "runas";
        
    // Start the new process
    try
    {
        Process.Start(processInfo);
    }
    catch (Exception)
    {
        // The user did not allow the application to run as administrator
        MessageBox.Show("Sorry, this application must be run as Administrator.");
    }

    // Shut down the current process
    Environment.Exit(0);
}
else
{
    // We are running as administrator
        
    // Do normal startup stuff...
}
}
