I have created a sample portlet using primefaces bridge in lifeary. The main functionality is create/edit/delete in some tables. How is it possible to split code of on page to more.
To be more specific I want when I click on a record to go to another xthml page in which I will load the data from selected record
You can use the following code to get portlet context and the for example user information
System.out.println("Getting user info");
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
PortletRequest portletRequest = (PortletRequest) externalContext.getRequest();
User user = PortalUtil.getUser(portletRequest);
Much concise way of doing this is
PortalRequest request = LiferayFacesContext.getPortalRequest();
User user = PoralUtil.getUser(portletRequest);
or to get the currently logged in user, use the following code
LiferayFacesContext.getInstance().getUser();
should give you the Liferay user object for the currently logged in user.

The docs for RefreshIndicator suggest you can programmatically trigger the refresh behaviour via the RefreshIndicatorState class.
How do I access an instance of this class, assuming I've added a RefreshIndicator widget to my application? I can't see a property to access it and I'm assuming createState() is only used by the Flutter framework.
To avoid an XY problem, I should explain my reason for doing this is to perform a visually pleasing refresh of my list when my user first opens the app. The list will be empty initially and the refresh will poll my server for data.
See https://docs.flutter.io/flutter/material/RefreshIndicatorState/show.html and a usage example in the Flutter Gallery
Essentially
var indicator = new GlobalKey<RefreshIndicatorState>();
and then
indicator.currentState.show();
after it's built.
I have a Laravel project where users have roles with permissions(I'm using
Zizaco/entrust) and the app is accessable just for registered user.
The application holds uploaded documents but this documents should not available for public view, on the other side this documents should be accessable in function of users permission.
My question: how to go in this case, how to protect documents in function of users permission?
I'm not sure if this will help, but you can create a special Controller for downloading/showing a document, where you can check permissions of a actual user.
From Entrust documentation, you can check if user should be able to see the document:
$user->hasRole('owner'); //returns boolean
So you can use this code from below in a Controller:
$user = User::where('username', '=', 'Mark')->first();
$pathToFile = Storage::get('file.pdf');
if ($user->hasRole('admin'))
{
return response()->download($pathToFile); //if you want to display a file, then change download to file
}
else
{
abort(403, 'Unauthorized action.');
}
Remember about adding this line to your controller:
use Zizaco\Entrust\Traits\EntrustUserTrait;
You can read more about responses here: https://laravel.com/docs/5.4/responses and files here: https://laravel.com/docs/5.4/filesystem
Look here for short syntax which will help you implement file downloads in routes.php without creating a new controller.

I want to know definition of New/Established user property in firebase. We can filter using these user property. I searched for it's definition in firebase but found nothing.
Here is the firebase link of user properties.

I need to log unique user sessions in Webmatrix / Razor / ASP.NET Web Pages. Does _appstart fire just when the app spins up the first time in IIS or does it fire once per unique user hit? If just once, how do I capture unique user sessions & settings?
UPDATE: I wasn't sure if the Global.asax events were fired under Razor / ASP.NET WebPages. I tested it out and the Session_Start event fires just fine. Question resolved.
void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
Dictionary<DateTime, String> d = new Dictionary<DateTime, String>();
Application.Lock();
if (Application["d"] != null)
{
d = (Dictionary<DateTime, String>)Application["d"];
}
d.Add(DateTime.Now, HttpContext.Current.Session.SessionID);
Application["d"] = d;
Application.UnLock();
}
To directly answer your question, _AppStart runs when the first user hits your site. Future users to the site do NOT cause _AppStart to run. There is no specific page or place to put code that runs for each unique user.
What you want to do is take a look at the ASP.Net Session object. In your page, you can store and retrieve data from Session like so:
#{
// Retrieve
var someSetting = Session["SomeSetting"]
// Store
Session["SomeSetting"] = someSetting;
}
ASP.Net will take care of making sure that the setting is stored per-browser-instance using Session Cookies. Note that if you're in a Web Farm environment, you'll need something more robust, but when you're talking about a single server, this should be fine.
If you want some more info, here's the official documentation for ASP.Net Session State: http://msdn.microsoft.com/en-us/library/ms178581.aspx
You have asked about logging "unique user sessions", which is a little confusing. All sessions are unique, but not all sessions belong to unique visitors. Returning visitors will start new sessions. If you want to keep a count of sessions, you can hook into the Session_Start event in Global.asax. If you want to count unique visitors, use cookies. Set them when a user visits if one hasn't already got a cookie. Ensure that their expiry is some time well into the future. If the visitor hasn't got a tracking cookie for your site, they must be new (or they might have deleted their cookie...)
My application is meant to speed up the retrieval of phone call information from our telephone system.
The best way to get this information is to create a new search on the telephone system's web interface and export the results to an Excel spreadsheet which my application then imports into a DataSet.
To get the export, from the login screen, the process goes as follows:
Log in
Navigate to Reports Page
Click "Extension Detail" link
Select "Extensions" CheckBox
Select the extensions (typically all the ones currently being used) from the listbox
Specify date range
Click on Export button
It's not a big job to do it manually every day, but, for reliability, it would be great if I can make my application do this automatically the first time it starts every day.
Since more than 1 person in the company is going to use this application, having a Windows Service do it would be even better.
I don't know if it'll help, but the system is Datatex Topaz Next Generation telephone management system: http://www.datatex.co.za/downloads/index.html#TNG
Can anyone give me a basic idea how to do this?
Also, can anyone post links (in comments if need be) to pages where I can learn more about how to do this?
I have done the something similar to fetch info from a website. I cannot give you a exact answer. But the idea is to send login info to the page with form values. If the site is relying on cookies, you can use this cookie aware WebClient:
public class CookieAwareWebClient : WebClient
{
private CookieContainer cookieContainer = new CookieContainer();
protected override WebRequest GetWebRequest(Uri address)
{
WebRequest request = base.GetWebRequest(address);
if (request is HttpWebRequest)
{
(request as HttpWebRequest).CookieContainer = cookieContainer;
}
return request;
}
}
You should be aware that some sites rely on a session id being passed so the first thing I did was to fetch the session id from the page:
var client = new CookieAwareWebClient();
client.Encoding = Encoding.UTF8;
var indexHtml = client.DownloadString(*index page url*);
string sessionID = fetchSessionID(indexHtml);
Then I had to log in to the page which you can do by uploading values to the page. You can see the specific form elements with "view source" but you have to know a little HTML to do so.
var values = new NameValueCollection();
values.Add("sessionid", sessionID); //Fetched session id
values.Add("brugerid", args[0]); //Username in my case
values.Add("adgangskode", args[1]); //Password in my case
values.Add("login", "Login"); //The login button
//Logging in
client.UploadValues(*url to login*, values); //If all goes perfect, I'm logged in now
And then I could download the page I needed. In your case you may use DownloadFile(...) if the file always have the same url (something like Export.aspx?From=2010-10-10&To=2010-11-11) or UploadValues(...) where you specify the values as before but saves the result.
string html = client.DownloadString(*url*);
It seems you have a lot more steps than I did. But the principle is the same. To see what values your send to the site to login etc. you can use programs such as Fiddler (windows) which can capture the activity going on. Essential you just do exactly the same thing but watch out for session id etc. which is temporary.
The best idea is really to use some native way to fetch data, but if don't got the code, database etc. you have to do it the ugly way. You may also need a HTML parser to fetch the data (ups, you don't because you export to a file). And last but not least, keep in mind that pages can change and there is great potential to fail to login, parse etc.
Please ask for if you are uncertain what is going on.

With a HTTP client, you need to do the following:
Log in, using cookies or HTTP authentication
Request a page
Submit form data
This means that you need some class or component in your program that can do HTTP, cookies, authentication and forms. With this, you do the same requests a user would do.
