I'm starting with C# and I need a strength.

I tried to connect with the database, using the entity framework.

In the output of visual studio arose the following message:

System. TypeLoadException: Could not load type 'NuGet. NuGetConstants' from assembly 'NuGet. VisualStudio.

So I couldn't generate the classes.

Has anyone been through that?

I need help, I would like to display an interstitial ad after the initial screen loads, but my code is giving the following failure:

java.lang.IllegalStateException: isLoaded must be called on the main UI thread.

Here's my code:

public class SplashScreenActivity extends AppCompatActivity {
InterstitialAd mInterstitialAd;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);

    // FIREBASE INTERSTICIAL
    mInterstitialAd = new InterstitialAd(this);
    mInterstitialAd.setAdUnitId("ca-app-pub-2565065222479596/3931476543");

    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
            requestNewInterstitial();
        }
    });

    requestNewInterstitial();

    Toast.makeText(this,"* Necessário Acesso a Internet *",Toast.LENGTH_LONG).show();

    Thread timerThread = new Thread() {
        public void run() {
            try {
                sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            } finally {

                if (mInterstitialAd.isLoaded()) {
                    mInterstitialAd.show();
                    Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
                    startActivity(intent);
                }
                else
                {
                    Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
                }
            }

        }
    };
    timerThread.start();

}

// FIREBASE INTERSTICIAL
private void requestNewInterstitial() {
    AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice("SEE_YOUR_LOGCAT_TO_GET_YOUR_DEVICE_ID")
            .build();

    mInterstitialAd.loadAd(adRequest);
}

}

Even after the debugging, I couldn't understand the reason for the mistake.

I would just display an interstitial right after the home screen or when I open the main activity.

Thank you so much!

IReport

Change Report Image Field Type to java.io.InputStream. Creates a parameter variable $P{imagem} type InputStream IReport.

JAVA:

InputStream imgPath =  new FileInputStream("C://images//sua_imagem.jpg");
HashMap<String, Object> params = new HashMap<String, Object>();

params.put("imagem",imgPath );

You can recover the yes from your classpath :

String path  = System.getProperty("user.dir") + "\fotos\ICONE3.png" );

Or the yes in Web application:

    HttpServletRequest request;

ServletContext context = request.getServletContext();

InputStream path = context.getResourceAsStream("/images/logo.jpg")

If all you want is an InputStream you can create using new FileInputStream(path), or getResourceAsStream().

Change this passage:

 String foto = System.getProperty("user.dir") + "\fotos\ICONE3.png";

InputStream path = ClassLoader.getSystemResourceAsStream( foto );

To:

 String foto = System.getProperty("user.dir") + "\fotos\ICONE3.png";

InputStream path =  new FileInputStream(foto);

So it worked out in your pit because it is an application DESKTOP and the image is external more with inputStream would be right also:

HashMap<String, Object> params = new HashMap<String, Object>();

params.put("imagem", System.getProperty("user.dir") + "\fotos\ICONE3.png" );

jasper. jrxml

Try this on field you want to print only conditionally... No.Print When Expression" only show when ($P{imagem} != null).

Good afternoon.

Maybe it's a different setting from the Android Studio emulator for the physical phone you're using for testing. I suggest you check the SDK Tools and also if the mobile is allowed to Developer

I need an algorithm that manages all possible arrangements for n elements n positions, that is, No! is the amount of possible arrangements, as in the example below:

n = 3
3! = 6 arranjos
123

132

213

231

312

321

I'm trying to create it in JavaScript, but it's not working.

function partida(){

var nc = 4;

var nl = fatorial(nc);

var jogada = new Array(nl);
for (i = 0; i < nl; i++){
    jogada[i] = new Array(nc);
}

for (c = 0; c < nc; c++){
    var q = fatorial(nc - c)/(nc - c);
    for (l = 0; l < nl; l++){
        jogada[l][c] = Math.trunc(l/q) + c;
    }
}

textarea = document.getElementById('arranjos');
for (l = 0; l < nl; l++){
    textarea.innerHTML += (jogada[l].toString()).replace(/,/g, "");
    textarea.innerHTML += '\n';
}

}

I'm doing a program that calculates a final note adding the numbers and dividing them by 4. I would like to add the typing function as many notes as users want.

This is the code I have at the moment:

        int num0;
        int num1;
        int num2;
        int num3;
        int sum;
        int div;
        String input0 = "";
        String input1 = "";
        String input2 = "";
        String input3 = "";
        Console.WriteLine("Calculador de média escolar\n");
        Console.WriteLine("Por favor, digite o primeiro número:");
        input0 = Console.ReadLine();
        Console.WriteLine("Por favor, digite o segundo número:");
        input1 = Console.ReadLine();
        Console.WriteLine("Por favor, digite o terceiro número:");
        input2 = Console.ReadLine();
        Console.WriteLine("Por favor, digite o quarto número:");
        input3 = Console.ReadLine();
        num0 = Convert.ToInt32(input0);
        num1 = Convert.ToInt32(input1);
        num2 = Convert.ToInt32(input2);
        num3 = Convert.ToInt32(input3);
        sum = num0 + num1 + num2 + num3;
        div = sum / 4;
        Console.WriteLine("A nota é: " +div);
        Console.ReadLine();

I'd appreciate your help.

I believe you can do two ways.

1st Option

Iterable<String> keys = keysWithPrefix(pre);
Iterator<String> it = keys.iterator();
while(it.hasNext()){
   System.out.println(it.next());
}

2nd Option

Iterable<String> keys = keysWithPrefix(pre);
for(String key: keys){
   System.out.println(key);
}

These references are the corporate frameworks or libraries that companies create and leave them on the developers' machines in fixed paths's is the worst way to deal with them.

Component management

For .Net there is a rather elegant solution for server-side components: Nuget.

Nuget is package server, it is possible that it is already your knowledge, through the Nuget.org website. The interesting thing is that it is not necessary to expose the packages through the public site, since it is possible to have a private repository of packages in the company.

One can start by creating a folder on the network with share for the developers, and put the packages there, with the extension No.. Or use a server application, with portal, much like the public site and even features that go from authentication to feeds to other package types. Proget has a version for free start use and then paid versions with advanced features. There are also other servers, type Myget, etc...

Configure a Nuget repository in Visual Studio

To configure a nuget server, Proget, for example, or even a folder, such as feed in Visual Studio, go to the Tools > Options menu.

In the window click the field Search Options and type Nuget (1), click menu Package Sources (2), click the button with the + (3) sign, give a name (4), and in the field Source place the feed address (5) and click Update (6). It is interesting to place as the first option, so with it selected, click the arrow that points up (7), so when you search for a package, priority will be given to the internal server of Nuget.

See that in this example I put a shared folder on the network, which will have the .nupkg files. If you use a server, the Source should be an RSS feed address.

You can do something like this: inside your component-btns you will set some Outputs

@Component({
   selector: 'component-btns',
   templateUrl: 'component-btns.component.html'
})
export class ComponentBtns {
    @Output('botao1')
    botao1Event: EventEmitter<any> = new EventEmitter();
@Output('botao2)
botao2Event: EventEmitter&lt;any&gt; = new EventEmitter();

@Output('botao3')
botao3Event: EventEmitter&lt;any&gt; = new EventEmitter();

botao1Click() {
    this.botao1Event.emit();
}

botao2Click() {
    this.botao2Event.emit();
}

botao3Click() {
    this.botao3Event.emit();
}

}

You can read about the EventEmitter https://angular.io/api/core/EventEmitter

Having this mounted, in the template you want to use component-btns you can use event in Output that you defined. Example:

<component-btns (botao1)="funcaoBotao1()" (botao2)="funcaoBotao2()" (botao3)="funcaoBotao3()"><component-btns>

In this way, when the button is clicked, it will perform the function within the ComponentBtns that will issue an event, in which your parent component will be listening and responding.

You can use the beforeEach Router or other equivalent if using another router to validate all protected routes, as per the https://router.vuejs.org/en/advanced/navigation-guards.html , to validate the token and permissions in the backend and receive a simple response of authorized or not from the backend so that the frontend will continue navigation to the route or not.

You can also define a method beforeEnter to validate a specific route:

const router = new VueRouter({
  routes: [
    {
      path: '/foo',
      component: Foo,
      beforeEnter: (to, from, next) => {
        // ...
      }
    }
  ]
})
