I generate a session in my code but then when using it in another file the session returns null, thx all!
this linux server primefaces,payara 5
public Usuarios loginUsuario(String usuario, String password) {

I'm checking, if a given user is part of a group by this code below. I'm getting
unauthorized exception
(0x80070005)
and I do not understand why? I'm using SPSecurity.RunWithElevatedPrivileges, so why it is giving me this exception!? Anybody a hint for me? Thanks in advance!
public bool IsUserInGroup(SPWeb web, string groupName, string user)
{
try
{
bool returnValue = false;
SPSecurity.RunWithElevatedPrivileges(() =>
{
if (web.Groups.OfType<SPGroup>().Where(g => g.Name == groupName).Count() > 0)
{
SPGroup spGroup = web.Groups[groupName];
if (spGroup.Users.OfType<SPUser>().Where(u => u.LoginName.Equals(user)).Count() > 0)
{
returnValue = true;
}
else
{
returnValue = false;
}
}
else
{
returnValue = false;
}
});
return returnValue;
}
catch (Exception exp)
{
Classes.Logs.Error.Log_Error("IsUserInGroup", "DocumentCenterItem.cs", exp.Message, DateTime.Now);
return false;
}
}
You need to create a new instance of SP Web inside elevated privileges. In your current implementation, you are reusing the web object which runs in current user context.
So, try and modify the below code as per your requirement :
public bool IsUserInGroup(SPWeb web, string groupName, string user)
{
try
{
bool returnValue = false;
SPSecurity.RunWithElevatedPrivileges(() =>
{
using(SPSite site = new SPSite(web.Site.ID))
{
using(SPWeb elevatedWeb = site.OpenWeb(web.ID))
{
if (elevatedWeb.Groups.OfType<SPGroup>().Where(g => g.Name == groupName).Count() > 0)
{
SPGroup spGroup = elevatedWeb.Groups[groupName];
if (spGroup.Users.OfType<SPUser>().Where(u => u.LoginName.Equals(user)).Count() > 0)
{
returnValue = true;
}
else
{
returnValue = false;
}
}
else
{
returnValue = false;
}
}
}
});
return returnValue;
}
catch (Exception exp)
{
Classes.Logs.Error.Log_Error("IsUserInGroup", "DocumentCenterItem.cs", exp.Message, DateTime.Now);
return false;
}
}
I have a self-hosted Web API OData v3 service:
public class Startup
{
public void Configuration(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Product>("Products");
config.MapODataServiceRoute(
routeName: "ODataRoute",
routePrefix: null,
model: builder.GetEdmModel());
app.UseWebApi(config);
}
}
I also have the following Controller, which exposes a full CRUD:
public class ProductsController : ODataController
{
ApplicationDbContext db = new ApplicationDbContext();
private bool ProductExists(int key)
{
return db.Products.Any(p => p.Id == key);

protected override void Dispose(bool disposing)

I am able to access this feed from a browser without any issues.
However, when I try to get Excel 2013 to use this data feed (using this url: http://localhost:8080/Products), I get this error:
"We can't use the data from this feed. Make sure the external data feed server is available and your connection information is correct"
What can I do to make Excel 2013 to work with this data feed?
Hi i am using windows phone 8 app. i want to set existing user login, i can add user registration but i can't do user login my code is give below.
public partial class LoginPage : PhoneApplicationPage
{
public LoginPage()
{
InitializeComponent();
}
public static class dal
{
public static SQLiteAsyncConnection connection;
public static bool isDatabaseExisting;
public static async void ConnectToDB()
{
try
{
StorageFile storageFile = await ApplicationData.Current.LocalFolder.GetFileAsync("Bestin.sqlite");
isDatabaseExisting = true;
}
catch (Exception ex)
{
isDatabaseExisting = false;
}
if (!isDatabaseExisting)
{
try
{
StorageFile databaseFile = await Package.Current.InstalledLocation.GetFileAsync("Bestin.sqlite");
await databaseFile.CopyAsync(ApplicationData.Current.LocalFolder);
isDatabaseExisting = true;
}
catch (Exception ex)
{
isDatabaseExisting = false;
}
}
if (isDatabaseExisting)
{
connection = new SQLiteAsyncConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path, "Bestin.sqlite"), true);
}
}
}
private void Click_Login(object sender, RoutedEventArgs e)
{
dal.ConnectToDB();
var query = dal.connection.QueryAsync<Task>("SELECT * FROM Task Where Email=" + "\'" + txtEmailaddress.Text + "\'" + "and Password=" + "\'" + txtPassword.Password + "\'").Result;
if (query == null)
{
// invalid Login credentials
}
else
{
// do login
}
}
}
I am using your code.I got error The system cannot find the file specified. (Exception from HRESULT: 0x80070002)
ok so do this ....
public static class dal
{
public static SQLiteAsyncConnection connection;
public static bool isDatabaseExisting;
public static async void ConnectToDB()
{
try
{
StorageFile storageFile = await ApplicationData.Current.LocalFolder.GetFileAsync("Bestin.sqlite");
isDatabaseExisting = true;
}
catch (Exception ex)
{
isDatabaseExisting = false;
}
if (!isDatabaseExisting)
{
try
{
StorageFile databaseFile = await Package.Current.InstalledLocation.GetFileAsync("Bestin.sqlite");
await databaseFile.CopyAsync(ApplicationData.Current.LocalFolder);
isDatabaseExisting = true;
}
catch (Exception ex)
{
isDatabaseExisting = false;
}
}
if (isDatabaseExisting)
{
connection = new SQLiteAsyncConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path, "Bestin.sqlite"), true);
}
}
}
make a class like above code for your database connection and call this at your application startup like this dal.ConnectToDB();
then in your loginpage do like this...
private void Click_Login(object sender, RoutedEventArgs e)
{
var query = dal.connection.QueryAsync<Task>("SELECT * FROM Task Where Email=" + "\'" + txtEmailaddress.Text + "\'" + "and Password=" + "\'" + txtPassword.Password + "\'").Result;
if(query == null)
{
// invalid Login credentials
}
else
{
// do login
}
}
you can try this ..
private void Click_Login(object sender, RoutedEventArgs e)
{
dbConn = new SQLiteConnection(DB_PATH);
var query = dbconn.QueryAsync<Task>("SELECT * FROM Task Where Email=" + "\'" + txtEmailaddress.Text + "\'" + "and Password=" + "\'" + txtPassword.Password + "\'").Result;
if(query == null)
{
// invalid Login credentials
}
else
{
// do login
}
}
Hi i got solution in my question..,
using (var dbConn = new SQLiteConnection(DB_PATH))
{
var existing = dbConn.Query<Userlist>("select * from Userlist Where Email=" + "\'" + txtEmailaddress.Text + "\'" + "and Password=" + "\'" + txtPassword.Text + "\'").FirstOrDefault();
if (existing != null)
{
NavigationService.Navigate(new Uri("/Input.xaml?selectedItem=", UriKind.Relative));
}
else
{
MessageBox.Show("invalid login");
}
}
I am working on foursquare API v2 in Android.

I want to know why i got the HTTP_BAD_REQUEST response code.
when doing a POST the parameters should not be part of the URL (specify them as parameters to the POST).
I solved the problem.

RMS is a record based data storage mechanism, so you can store multiple records very easily, see following blog to see how RMS works.
