Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

Most IIS sections are locked by default but you can "unlock" them by setting the attribute overrideModeDefault from "Deny" to "Allow" for the relevant section group by modifying the ApplicationHost.config file located in %windir%\system32\inetsrv\config in Administrator mode

You can check the framework on which system was created and developed, and then changes the framework of your current solution to the old framework. You can do this by right click on the solution and then choose properties. In Application section you can change the framework.

I found this question because I was having issues with the OPTIONS request most browsers send. My app was routing the OPTIONS requests and using my IoC to construct lots of objects and some were throwing exceptions on this odd request type for various reasons.

Basically put in an ignore route for all OPTIONS requests if they are causing you problems:

var constraints = new { httpMethod = new HttpMethodConstraint(HttpMethod.Options) };
config.Routes.IgnoreRoute("OPTIONS", "{*pathInfo}", constraints);

More info: Stop Web API processing OPTIONS requests

I did Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3 but it still did not work. Then looked in my project bin folder and saw that it still had the old System.Web.Mvc file.

So I manually copied the newer file from the package to the bin folder. Then I was up and running again.

Above things are really helpful.

While creating web services, If you will take case of services consumer will greatly appreciated. I tried to maintain uniformity of the output. Also you can give remark or actual error message. The web service consumer can only check IsSuccess true or not else will sure there is problem, and act as per situation.

  public class Response
    {
        /// <summary>
        /// Gets or sets a value indicating whether this instance is success.
        /// </summary>
        /// <value>
        /// <c>true</c> if this instance is success; otherwise, <c>false</c>.
        /// </value>
        public bool IsSuccess { get; set; } = false;

        /// <summary>
        /// Actual response if succeed 
        /// </summary>
        /// <value>
        /// Actual response if succeed 
        /// </value>
        public object Data { get; set; } = null;

        /// <summary>

        public string Remark { get; set; } = string.Empty;

        /// <value>

        public object ErrorMessage { get; set; } = null;


    }  




[HttpGet]
        public IHttpActionResult Employees()
        {
            Response _res = new Response();
            try
            { 
                DalTest objDal = new DalTest(); 
                _res.Data = objDal.GetTestData();
                _res.IsSuccess = true;
                return Ok<Response>(_res);
            }
            catch (Exception ex)
            {
                _res.IsSuccess = false;
                _res.ErrorMessage = ex;
                return ResponseMessage(Request.CreateResponse(HttpStatusCode.InternalServerError, _res )); 
            } 
        }

You are welcome to give suggestion if any :)

Incomplete information: we need to know which line is throwing the NullReferenceException in order to tell precisely where the problem lies.

Obviously, you are using an uninitialized variable (i.e., a variable that has been declared but not initialized) and try to access one of its non-static method/property/whatever.

Solution: - Find the line that is throwing the exception from the exception details - In this line, check that every variable you are using has been correctly initialized (i.e., it is not null)

Good luck.

I've got this error when I accidentally defined a property as a specific object type, instead of the interface type I have defined in UnityContainer.

For example:

Defining UnityContainer:

var container = new UnityContainer();
container.RegisterInstance(typeof(IDashboardRepository), DashboardRepository);
config.DependencyResolver = new UnityResolver(container);

SiteController (the wrong way - notice repo type):

private readonly DashboardRepository _repo;

public SiteController(DashboardRepository repo)
{
    _repo = repo;
}

SiteController (the right way):

private readonly IDashboardRepository _repo;

public SiteController(IDashboardRepository repo)
{
    _repo = repo;
}

Solved, just renamed the Global.asax or delete it fixed the problem :/

Other known related bugs I found on the web:

1. Global.asax.cs: must inherit from HttpApplication -> public class MvcApplication : HttpApplication
2. Project output must be the bin folder and not Bin/Debug, etc.
3. Iss application pool is not in the correct .net version.

if you can use LinqToObjects in your Project

private YourTextBox_TextChanged ( object sender, EventArgs e)
{
   return YourTextBox.Text.Where(c=> c.ToUpper());
}

An if you can't use LINQ (e.g. your project's target FW is .NET Framework 2.0) then

private YourTextBox_TextChanged ( object sender, EventArgs e)
{
   YourTextBox.Text = YourTextBox.Text.ToUpper();
}

Why Text_Changed Event ?

There are few user input events in framework..

1-) OnKeyPressed fires (starts to work) when user presses to a key from keyboard after the key pressed and released

2-) OnKeyDown fires when user presses to a key from keyboard during key presses

3-) OnKeyUp fires when user presses to a key from keyboard and key start to release (user take up his finger from key)

As you see, All three are about keyboard event..So what about if the user copy and paste some data to the textbox?

if you use one of these keyboard events then your code work when and only user uses keyboard..in example if user uses a screen keyboard with mouse click or copy paste the data your code which implemented in keyboard events never fires (never start to work)

so, and Fortunately there is another option to work around : The Text Changed event..

Text Changed event don't care where the data comes from..Even can be a copy-paste, a touchscreen tap (like phones or tablets), a virtual keyboard, a screen keyboard with mouse-clicks (some bank operations use this to much more security, or may be your user would be a disabled person who can't press to a standard keyboard) or a code-injection ;) ..

No Matter !

Text Changed event just care about is there any changes with it's responsibility component area ( here, Your TextBox's Text area) or not..

If there is any change occurs, then your code which implemented under Text changed event works..

using System;
using System.Data;
using System.Data.SqlClient;

    class sqlinsertdata
    {
        static void Main(string[] args)

            SqlConnection conn = new SqlConnection("Data source=USER-PC; Database=Emp123;User Id=sa;Password=sa123");
            conn.Open();
                SqlCommand cmd = new SqlCommand("insert into <Table Name>values(1,'nagendra',10000);",conn);
                cmd.ExecuteNonQuery();
                Console.WriteLine("Inserting Data Successfully");
                conn.Close();
        }
            catch(Exception e)
            {
                Console.WriteLine("Exception Occre while creating table:" + e.Message + "\t"  + e.GetType());
            }
            Console.ReadKey();

    }

I faced this error becouse I sent the Query string with wrong format

http://localhost:56110/user/updateuserinfo?Id=55?Name=Basheer&Phone=(111)%20111-1111
------------------------------------------^----(^)-----------^---...
--------------------------------------------must be &

so make sure your Query String or passed parameter in the right format

I got the same problem with dotnet core and managed to fix it by clearing the NuGet cache.

Open the powershell and enter the following command.

dotnet nuget locals all --clear

Then I closed Visual Studio, opened it again and entered the following command into the Package Manager Console:

Update-Package

NuGet should now restore all packages and popultes the nuget cache again.

After that I was able to build and start my dotnet core webapi in a Linux container.

I faced the same situation. Create your connection string as follows.

Replace

"connectionString": "Data Source=server name;Initial Catalog=DB name;User id=user id;Password=password;Integrated Security=True;MultipleActiveResultSets=True"

by

"connectionString": "Server=server name; Database=Treat; User Id=user id; Password=password; Trusted_Connection=False; MultipleActiveResultSets=true"

It require to include Content-Type:application/json in web api request header section when not mention any content then by default it is Content-Type:text/plain passes to request.

Best way to test api on postman tool.

For Visual Studio 2012 while debugging that error accrued

Website Menu -> Use IIS Express did it for me

Add following dll files to bin folder:

DotNetOpenAuth.AspNet.dll
DotNetOpenAuth.Core.dll
DotNetOpenAuth.OAuth.Consumer.dll
DotNetOpenAuth.OAuth.dll
DotNetOpenAuth.OpenId.dll
DotNetOpenAuth.OpenId.RelyingParty.dll

If you will not need them, delete dependentAssemblies from config named 'DotNetOpenAuth.Core' etc..

I had the same issue, and spent quite a bit of time trying to track down the solution. I had Anonymous Authentication set up at two different levels with two different users. Make sure that you're not overwriting your set up at a lower level.

Make sure you installed the nuget package Microsoft.AspNet.Identity.Owin. Then add System.Net.Http namespace.

Install .NET framework as below, it will work .NET version 4.5 as well.

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

Some time only give aspnet_regiis.exe -i don't work so give aspnet_regiis.exe -ir in above path.

Windows Firewall was creating this error for me. SMTP was trying to post to GMAIL at port 587. Adding port 587 to the Outbound rule [Outbound HTTP/SMTP/RDP] resolved the issue.

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

Considering that a LocalDb instance only intended for use in development. LocalDb is not available for production servers When you deploy the final result.

I think your connection string is pointing to a LocalDb instance and you need to take certain steps to turn it into the SQL Server database. It's not just a matter of copying an mdf file either. It will possibly differ from one hosting company to another, but typically, you need to create a backup of your existing database (a .bak file) and then restore that to the hosting company's SQL Server. You should ask them where you can find instructions on deploying your database into production.

You can achieve it by code also, In you Global.asax file in Session_Start event write response.redirect to your start page like following.

void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

            Response.Redirect("~/Index.aspx");

        }

You can get redirect page name from database or any other storage to change the application start page while application is running no need to edit web.config or change any IIS settings

I met the same problem and I resolved it by setting CopyLocal to true for the following libs:

System.Web.Http.dll
System.Web.Http.WebHost.dll
System.Net.Http.Formatting.dll

I must add that I use MVC4 and NET 4

You are missing setting what field is the Text and Value in the SelectList itself. That is why it does a .ToString() on each object in the list. You could think that given it is a list of SelectListItem it should be smart enough to detect this... but it is not.

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Selected = false, Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text", 1);

BTW, you can use a list of array of any type... and then just set the name of the properties that will act as Text and Value.

I think it is better to do it like this:

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text");

I removed the -1 item, and the setting of each items selected true/false.

Then, in your view:

@Html.DropDownListFor(m => m.UserType, Model.UserTypeOptions, "Select one")

This way, if you set the "Select one" item, and you don't set one item as selected in the SelectList, the UserType will be null (the UserType need to be int? ).

If you need to set one of the SelectList items as selected, you can use:

u.UserTypeOptions = new SelectList(options, "Value" , "Text", userIdToBeSelected);

If the issue remain after uninstalling and installing Microsoft.AspNet.WebApi.WebHost then also add followings in web.config for globalconfiguration to work

 <dependentAssembly>
        <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.2.0.0" />
      </dependentAssembly>

All is right but in my case i have two class like this

namespace WebAPI.Model
{
   public class ProductsModel
{ 
        [Table("products")]
        public class Products
        {
            [Key]
            public int slno { get; set; }

            public int productId { get; set; }
            public string ProductName { get; set; }

            public int Price { get; set; }
}
        }
    }

After deleting the upper class it works fine for me.

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

I got this error while trying to host a WCF service in an empty ASP.NET application. The whole solution was using .NET 4.5 platform, on IIS 8.5 running on Windows 8.1. The gotcha was to

1. Open up "Turn Windows Features on or off"

2. Go to WCF section under ASP.NET 4.5 advanced services

3. Check HTTP Activation.

4. You'll be asked to restart the system.

   

This should Fix the HTTP 500.19!

EDIT 11-FEB-2016 Just got an issue on Windows 10 Pro, IIS 10, This time, it was an HTTP 404.0. The fix is still the same, turn on "HTTP Activation" under Windows Features -> .NET Framework 4.6 Advanced Services -> WCF Services -> HTTP Activation

In my case the issue didn't resolve by following any of the above methods. I had all the paths in my package config correct and the dll's were in place as referred, I was still getting run time error for System.Web.WebPages.Razor. I changed the localhost port number and this worked

I am not sure of why I had the issue and why changing the port number resolved it. Just posting this as I feel this might be useful for someone out there.

This error is very non-descriptive but the key here is that 'ID' is in uppercase. This indicates that the route has not been correctly set up. To let the application handle URLs with an id, you need to make sure that there's at least one route configured for it. You do this in the RouteConfig.cs located in the App_Start folder. The most common is to add the id as an optional parameter to the default route.

public static void RegisterRoutes(RouteCollection routes)
{
    //adding the {id} and setting is as optional so that you do not need to use it for every action
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

Now you should be able to redirect to your controller the way you have set it up.

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index","ProductImageManager", new { id });

    //if the action is in the same controller, you can omit the controller:
    //RedirectToAction("Index", new { id });
}

In one or two occassions way back I ran into some issues by normal redirect and had to resort to doing it by passing a RouteValueDictionary. More information on RedirectToAction with parameter

return RedirectToAction("Index", new RouteValueDictionary( 
    new { controller = "ProductImageManager", action = "Index", id = id } ) 
);

If you get a very similar error but in lowercase 'id', this is usually because the route expects an id parameter that has not been provided (calling a route without the id /ProductImageManager/Index). See this so question for more information.

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
" Why is Asp.Net Identity IdentityDbContext a Black-Box?
How can I change the table names when using Visual Studio 2013 AspNet Identity?
Merge MyDbContext with IdentityDbContext"

To answer to all of these questions we need to understand that IdentityDbContext is just a class inherited from DbContext.

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:

First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.

   public class ApplicationDbContext 
    : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

Extra Notes:

1) We can also change asp.net Identity default table names with the following solution:

    public class ApplicationDbContext : IdentityDbContext
    {    
        public ApplicationDbContext(): base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<IdentityUser>().ToTable("user");
            modelBuilder.Entity<ApplicationUser>().ToTable("user");

            modelBuilder.Entity<IdentityRole>().ToTable("role");
            modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
        }
    }

2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    public ApplicationRole() 
    {
        this.Id = Guid.NewGuid().ToString();
    }

    public ApplicationRole(string name)
        : this()
    {
        this.Name = name;
    }

    // Add any custom Role properties/code here
}


// Must be expressed in terms of our custom types:
public class ApplicationDbContext 
    : IdentityDbContext<ApplicationUser, ApplicationRole, 
    string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.

Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code

You have upgraded to Razor 3. Remember that VS 12 (until update 4) doesn't support it. Install The Razor 3 from nuget or downgrade it through these step

It depends on the configuration of the application as well as on IIS as this gentleman in the below link has rightfully explained. Please see his article below

http://richhewlett.com/2011/02/15/getting-a-users-username-in-asp-net/

Open up the applicationHost.config file located in the C:\Users[userid]\Documents\IISExpress\config folder. Inside this file change the overrideModeDefault of anonymousAthentication and windowsAuthentication to "Allow"

 <sectionGroup name="security">
                <section name="access" overrideModeDefault="Deny" />
                <section name="applicationDependencies" overrideModeDefault="Deny" />
                <sectionGroup name="authentication">
                    <section name="anonymousAuthentication" overrideModeDefault="Allow" />
                    <section name="basicAuthentication" overrideModeDefault="Deny" />
                    <section name="clientCertificateMappingAuthentication" overrideModeDefault="Deny" />
                    <section name="digestAuthentication" overrideModeDefault="Deny" />
                    <section name="iisClientCertificateMappingAuthentication" overrideModeDefault="Deny" />
                    <section name="windowsAuthentication" overrideModeDefault="Allow" />
                </sectionGroup>

Next change lockItem to be "false" for AnonymousAuthenticationModule and WindowsAuthenticationModule

  <system.webServer>
            <modules>
                <!--
                <add name="HttpCacheModule" lockItem="true" />
-->
                <add name="DynamicCompressionModule" lockItem="true" />
                <add name="StaticCompressionModule" lockItem="true" />
                <add name="DefaultDocumentModule" lockItem="true" />
                <add name="DirectoryListingModule" lockItem="true" />
                <add name="IsapiFilterModule" lockItem="true" />
                <add name="ProtocolSupportModule" lockItem="true" />
                <add name="HttpRedirectionModule" lockItem="true" />
                <add name="ServerSideIncludeModule" lockItem="true" />
                <add name="StaticFileModule" lockItem="true" />
                <add name="AnonymousAuthenticationModule" lockItem="false" />
                <add name="CertificateMappingAuthenticationModule" lockItem="true" />
                <add name="UrlAuthorizationModule" lockItem="true" />
                <add name="BasicAuthenticationModule" lockItem="true" />
                <add name="WindowsAuthenticationModule" lockItem="false" />

Making these changes will allow the existing web config settings to override what is in the applicationHost file for IIS Express.

I fixed this by reinstalling the NuGet package, which corrects broken dependencies. From the package manager, run:

Update-Package Microsoft.AspNet.WebApi -reinstall

I did like this :

public static class JsonExtension
{
    public static string ToJson(this object value)
    {
        var settings = new JsonSerializerSettings
        {
            ContractResolver = new CamelCasePropertyNamesContractResolver(),
            NullValueHandling = NullValueHandling.Ignore,
            ReferenceLoopHandling = ReferenceLoopHandling.Serialize
        };
        return JsonConvert.SerializeObject(value, settings);
    }
}

this a simple extension method in MVC core , it's going to give the ToJson() ability to every object in your project , In my opinion in a MVC project most of object should have the ability to become json ,off course it depends :)

Web.Config file:

<configuration>
 <system.net>
        <mailSettings>
            <smtp from="[email protected]">
                <network host="smtp.gmail.com" 
                 port="587" 
                 userName="[email protected]" 
                 password="yourpassword" 
                 enableSsl="true"/>
            </smtp>
        </mailSettings>
</system.net>
</configuration>

One problem here is that your method expects int values while you are passing string from ajax call. Try to change it to string and parse inside the webmethod if necessary :

[System.Web.Services.WebMethod]
public static string AddTo_Cart(string quantity, string itemId)
{
    //parse parameters here
    SpiritsShared.ShoppingCart.AddItem(itemId, quantity);      
    return "Add";
}

Edit : or Pass int parameters from ajax call.

Same issue happened with me when i mistakenly added some text in front of the top directive of the master page all the controls across all the page included in my project started showing, does not exist in the current context. After spending much time across the forum and self analysis, i found the mistakenly added text and removed but it does not solved the problem. Then i had to click on each error to open the associated page so that VS can load the page and recognize it, once the code was loaded in VS, error from those particular page started disappearing because VS recognized it. clicking on each error, loading each page in VS editor did the trick for me and you have to do it only once because later it will be automatically recognized by VS. I would say it is a Visual Studio Glitch.

After modifying the References in the Web.config file as mentioned above, we resolved the references.

I was facing similar issue.

For us we have reference Microsoft.Data.Edm.dll and OData.dll and other assemblies from Program Files:

C:\Program Files (x86)\Microsoft WCF Data Services\5.0
                          \bin\.NETFramework\Microsoft.Data.Edm.dll

and

C:\Program Files (x86)\Microsoft WCF Data Services\5.0
                        \bin\.NETFramework\Microsoft.Data.OData.dll

and version was 5.6.4.

Once I change the reference of both assemblies to C:\....Project\packages\Microsoft.Data.Edm.5.6.0 , the issue was resolved

For some reason Andrew method of creating the checkbox by hand didn't work for me using Mvc 5. Instead I used this

@Html.CheckBox("checkResp")

to create a checkbox that would play nice with the controller.

Best way to make drop down list:

grid.Column("PriceType",canSort:true,header: "PriceType",format: @<span>
    <span id="[email protected]">@item.PriceTypeDescription</span>
    @Html.DropDownList("PriceType"+(int)item.ShoppingCartID,new SelectList(MvcApplication1.Services.ExigoApiContext.CreateODataContext().PriceTypes.Select(s => new { s.PriceTypeID, s.PriceTypeDescription }).AsEnumerable(),"PriceTypeID", "PriceTypeDescription",Convert.ToInt32(item.PriceTypeId)), new { @class = "PriceType",@style="width:120px;display:none",@selectedvalue="selected"})
        </span>),

protected void DescargarArchivo(string strRuta, string strFile)
{
    FileInfo ObjArchivo = new System.IO.FileInfo(strRuta);
    Response.Clear();
    Response.AddHeader("Content-Disposition", "attachment; filename=" + strFile);
    Response.AddHeader("Content-Length", ObjArchivo.Length.ToString());
    Response.ContentType = "application/pdf";
    Response.WriteFile(ObjArchivo.FullName);
    Response.End();


}

I just restarted Visual Studio and did IISRESET which solved the problem.

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

I also had same issue. I investigated and found missing {action} attribute from route template.

Before code (Having Issue):

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

After Fix(Working code):

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

Here is how I fixed this issue:

Open the nuget package manager console and install the below nuget packages:

Install-Package WebMatrix.Data
Install-Package Microsoft.AspNet.WebHelpers
Update-Package

Clean the solution, rebuild and my asp.net web app starts working!

1. Make sure that you have Office runtime installed on the server.
2. If you are using Windows Server 2008 then using office interops is a lenghty configuration and here are the steps.

Better is to move to Open XML or you can configure as below

• Install MS Office Pro Latest (I used 2010 Pro)
• Create User ExcelUser. Assign WordUser with Admin Group
• Go to Computer -> Manage
• Add User with below options
• User Options Password Never Expires
• Password Cannot Be Change

Com+ Configuration

• Go to Control Panel - > Administrator -> Component Services -> DCOM Config
• Open Microsoft Word 97 - 2003 Properties
• General -> Authentication Level : None
• Security -> Customize all 3 permissions to allow everyone
• Identity -> This User -> Use ExcelUser /password
• Launch the Excel App to make sure everything is fine

3.Change the security settings of Microsoft Excel Application in DCOM Config.

Controlpanel --> Administrative tools-->Component Services -->computers --> myComputer -->DCOM Config --> Microsoft Excel Application.

Right click to get properties dialog. Go to Security tab and customize permissions

See the posts here: Error while creating Excel object , Excel manipulations in WCF using COM

If using IIS:

• control panel
• Programs
• open or close windows features
• tick internet information services
• then restart your visual studio

If using IIS Express:

Open 'Add/Remove Programs' from the old control panel and run a repair on IIS Express Or you might go Control Panel ->> Programs ->> Programs and Features ->> Turn Windows features on or off ->> Internet Information Services and check the checkbox as shown in the picture below:

Ensure that binary files are under "bin" subdirectory of your ".svc" file

Change this part in your Web.config, according to the below code.(try this, it works to me.)

<entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="Data Source=.; Integrated Security=True; MultipleActiveResultSets=True" />   
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>

Different case but may help someone,

In my case Window firewall was enabled on Server,

Two thinks can be done,

1) Disable windows firewall (your on risk but it will get thing work)

2) Add port in inbound rule.

Thanks .

When publishing to IIS, by Web Deploy, I just checked the File Publish Options and executed. Now it works! After this deploy the checkboxes do not need to be checked. I don't think this can be a solutions for everybody, but it is the only thing I needed to do to solve my problem. Good luck.

I understand that this error can occur because of many different reasons. In my case it was because I uninstalled WSUS service from Server Roles and the whole IIS went down. After doing a bit of research I found that uninstalling WSUS removes a few dlls which are used to do http compression. Since those dlls were missing and the IIS was still looking for them I did a reset using the following command in CMD:

appcmd set config -section:system.webServer/httpCompression /-[name='xpress']

Bingo! The problem is sorted now. Dont forget to run it as an administrator. You might also need to do "iisreset" as well. Just in case.

Hope it helps others. Cheers

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

All you have to do is In your bLoanButton_Click , add a line to rebind the Grid to the SqlDataSource :

protected void bLoanButton_Click(object sender, EventArgs e)
{

//your same code
........

GridView1.DataBind();


}

regards

CheckBoxFor takes a bool, you're passing a List<CheckBoxes> to it. You'd need to do:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, new { id = "employmentType_" + i })
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.DisplayFor(m => m.EmploymentType[i].Text)
}

Notice I've added a HiddenFor for the Text property too, otherwise you'd lose that when you posted the form, so you wouldn't know which items you'd checked.

Edit, as shown in your comments, your EmploymentType list is null when the view is served. You'll need to populate that too, by doing this in your action method:

public ActionResult YourActionMethod()
{
    CareerForm model = new CareerForm();

    model.EmploymentType = new List<CheckBox>
    {
        new CheckBox { Text = "Fulltime" },
        new CheckBox { Text = "Partly" },
        new CheckBox { Text = "Contract" }
    };

    return View(model);
}

I can't tell from the context you supply, but if it's something you just need to do at app startup, you can still use Server.MapPath in WebApiHttpApplication; e.g. in Application_Start().

I'm just answering your direct question; the already-mentioned HostingEnvironment.MapPath() is probably the preferred solution.

Here is a good eplanation: ASP.NET MVC – Multiple buttons in the same form

In 2 words:
you may analize value of submitted button in yout action
or
make separate actions with your version of ActionMethodSelectorAttribute (which I personaly prefer and suggest).

The problem you are having is the query command is taking too long. I believe that the default timeout for a query to execute is 15 seconds. You need to set the CommandTimeout (in seconds) so that it is long enough for the command to complete its execution. The "CommandTimeout" is different than the "Connection Timeout" in your connection string and must be set for each command.

In your sql Selecting Event, use the command:

e.Command.CommandTimeout = 60

for example:

Protected Sub SqlDataSource1_Selecting(sender As Object, e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs)
    e.Command.CommandTimeout = 60
End Sub

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

You have:

foreach (var category in Model.Categories)

and then

@foreach (var product in Model)

Based on that view and model it seems that Model is of type Product if yes then the second foreach is not valid. Actually the first one could be the one that is invalid if you return a collection of Product.

UPDATE:

You are right, I am returning the model of type Product. Also, I do understand what is wrong now that you've pointed it out. How am I supposed to do what I'm trying to do then if I can't do it this way?

I'm surprised your code compiles when you said you are returning a model of Product type. Here's how you can do it:

@foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>

    <div>
        <ul>    
            @foreach (var product in category.Products)
            {
                <li>
                    put the rest of your code
                </li>
            }
        </ul>
    </div>
}

That suggest that instead of returning a Product, you return a collection of Category with Products. Something like this in EF:

// I am typing it here directly 
// so I'm not sure if this is the correct syntax.
// I assume you know how to do this,
// anyway this should give you an idea.
context.Categories.Include(o=>o.Product)

You cannot use var in a field, only on local variables.

But even this won't work:

Site master = Master as Site;

Because you cannot use this in a field and Master as Site is the same as this.Master as Site. So just initialize the field from Page_Init when the page is fully initialized and you can use this:

Site master = null;

protected void Page_Init(object sender, EventArgs e)
{            
    master = this.Master as Site;
}

I had to add the ?wsdl parameter to the end of the url. For example: http://localhost:8745/YourServiceName/?wsdl

Not clear where My_ConnectionString is coming from in your example, but try this

System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString

like this

Dim DBConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("My_ConnectionString").ConnectionString)

Each individual Web App under an IIS Web Site can use a different App Pool.

Verify the App Pool assigned to your app (not just the root site per your pictures) is .NET 4.0 compatible:

1. Expand Default Web Site
2. Right click on ProjectPALS, choose 'Manage Application' then 'Advanced...'
3. Observe the 'Application Pool' your app is running as under the site
4. Change to another App Pool if neccessary

Check your runtime tag inside the web.config, and verify you have something like this declared:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
.....
</runtime>

Actually jessehouwing gave the solution for normal scenario.

But in my case I have enabled 2 types of session in my web.config file

It's like below.

First one :

<modules runAllManagedModulesForAllRequests="true">
        <remove name="Session" />
        <add name="Session" type="System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>

Second one :

<sessionState mode="Custom" customProvider="DefaultSessionProvider">
            <providers>
                <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="PawLoyalty" applicationName="PawLoyalty"/>
            </providers>
 </sessionState>

So in my case I have to comment Second one.B'cos that thing for the production.When I commented out second one my problem vanished.

You are using a wrong overload of the Html.ActionLink helper. What you think is routeValues is actually htmlAttributes! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.

Here's what you are using:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // routeValues
    new {                                                     // htmlAttributes
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    }
)

and here's what you should use:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // controllerName
    new {                                                     // routeValues
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    },
    null                                                      // htmlAttributes
)

Also there's another very serious issue with your code. The following routeValue:

replyblogPostmodel = Model

You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel parameter from your controller action. You should use the blogPostId parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:

public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
    BlogPostModel model = repository.Get(blogPostId);
    ...
}

As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:

@Html.ActionLink(
    linkText: "Reply",
    actionName: "BlogReplyCommentAdd",
    controllerName: "Blog",
    routeValues: new {
        blogPostId = blogPostId, 
        captchaValid = Model.AddNewComment.DisplayCaptcha
    },
    htmlAttributes: null
)

Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

Wrap your all statements in !IsPostBack condition on page load.

protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      // all statements
   }
}

This will fix your issue.

You're passing the same model to the partial view as is being passed to the main view, and they are different types. The model is a DbSet of Notes, where you need to pass in a single Note.

You can do this by adding a parameter, which I'm guessing as it's the create form would be a new Note

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

Here is my solution. Use [ExportModelStateToTempData] / [ImportModelStateFromTempData] is uncomfortable in my opinion.

~/Views/Home/Error.cshtml:

@{
    ViewBag.Title = "Error";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Error</h2>
<hr/>

<div style="min-height: 400px;">

    @Html.ValidationMessage("Error")

    <br />
    <br />

    <button onclick="Error_goBack()" class="k-button">Go Back</button>
    <script>
        function Error_goBack() {
            window.history.back()
        }
    </script>

</div>

~/Controllers/HomeController.sc:

public class HomeController : BaseController
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Error()
    {
        return this.View();
    }

    ...
}

~/Controllers/BaseController.sc:

public class BaseController : Controller
{
    public BaseController() { }

    protected override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        if (filterContext.Result is ViewResult)
        {
            if (filterContext.Controller.TempData.ContainsKey("Error"))
            {
                var modelState = filterContext.Controller.TempData["Error"] as ModelState;
                filterContext.Controller.ViewData.ModelState.Merge(new ModelStateDictionary() { new KeyValuePair<string, ModelState>("Error", modelState) });
                filterContext.Controller.TempData.Remove("Error");
            }
        }
        if ((filterContext.Result is RedirectResult) || (filterContext.Result is RedirectToRouteResult))
        {
            if (filterContext.Controller.ViewData.ModelState.ContainsKey("Error"))
            {
                filterContext.Controller.TempData["Error"] = filterContext.Controller.ViewData.ModelState["Error"];
            }
        }

        base.OnActionExecuted(filterContext);
    }
}

    public ActionResult Index()
    {
        return View();
    }

    public ActionResult Details(int id)
    {
        if (id != 5)
        {
            ModelState.AddModelError("Error", "Specified row does not exist.");
            return RedirectToAction("Error", "Home");
        }
        else
        {
            return View("Specified row exists.");
        }
    }
}

I wish you successful projects ;-)

One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.

But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this, you just need to add this attribute in every action method.

Here is the Class which overrides ActionFilterAttribute.

public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

            // check if session is supported
            CurrentCustomer objCurrentCustomer = new CurrentCustomer();
            objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
            if (objCurrentCustomer == null)
            {
                // check if a new session id was generated
                filterContext.Result = new RedirectResult("~/Users/Login");
                return;
            }

            base.OnActionExecuting(filterContext);
        }
    }

Then in action just add this attribute like so:

[SessionExpire]
public ActionResult Index()
{
     return Index();
}

This will do you work.

We ran into this problem and tracked it down to the Geocoding.net NuGet package that we were using to help with our Google Maps views (Geocoding.net version 3.1.0 published 2/4/2014).

The Geocoding dll appears to be .Net 4.0 when you examine the package file or view it using Jet Brains’ Dot Peek application; however, a colleague of mine says that it was compiled using ilmerge so it is most likely related to the ilmerge problems listed above.

It was a long process to track it down. We fetched different changesets from TFS till we narrowed it down to the changeset that added the aforementioned NuGet package. After removing it, we were able to deploy to our .NET 4 server.

I think this confusing exception occurs when you use a variable in a lambda which is a null-reference at run-time. In your case, I would check if your variable calculationViewModel is a null-reference.

Something like:

public ActionResult MNPurchase()
{
    CalculationViewModel calculationViewModel = (CalculationViewModel)TempData["calculationViewModel"];

    if (calculationViewModel != null)
    {
        decimal OP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.SalesPrice)
            .FirstOrDefault()
            .OP;

        decimal MP = landTitleUnitOfWork.Sales.Find()
            .Where(x => x.Min >= calculationViewModel.MortgageAmount)
            .FirstOrDefault()
            .MP;

        calculationViewModel.LoanAmount = (OP + 100) - MP;
        calculationViewModel.LendersTitleInsurance = (calculationViewModel.LoanAmount + 850);

        return View(calculationViewModel);
    }
    else
    {
        // Do something else...
    }
}

In ASP.Net Core anti forgery token is automatically added to forms, so you don't need to add @Html.AntiForgeryToken() if you use razor form element or if you use IHtmlHelper.BeginForm and if the form's method isn't GET.

It will generate input element for your form similar to this:

<input name="__RequestVerificationToken" type="hidden" 
       value="CfDJ8HSQ_cdnkvBPo-jales205VCq9ISkg9BilG0VXAiNm3Fl5Lyu_JGpQDA4_CLNvty28w43AL8zjeR86fNALdsR3queTfAogif9ut-Zd-fwo8SAYuT0wmZ5eZUYClvpLfYm4LLIVy6VllbD54UxJ8W6FA">

And when user submits form this token is verified on server side if validation is enabled.

[ValidateAntiForgeryToken] attribute can be used against actions. Requests made to actions that have this filter applied are blocked unless the request includes a valid antiforgery token.

[AutoValidateAntiforgeryToken] attribute can be used against controllers. This attribute works identically to the ValidateAntiForgeryToken attribute, except that it doesn't require tokens for requests made using the following HTTP methods: GET HEAD OPTIONS TRACE

Additional information: docs.microsoft.com/aspnet/core/security/anti-request-forgery

You can solve your problem with help of Attribute routing

Controller

[Route("api/category/{categoryId}")]
public IEnumerable<Order> GetCategoryId(int categoryId) { ... }

URI in jquery

api/category/1

Route Configuration

using System.Web.Http;

namespace WebApplication
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API routes
            config.MapHttpAttributeRoutes();

            // Other Web API configuration not shown.
        }
    }
}

and your default routing is working as default convention-based routing

Controller

public string Get(int id)
    {
        return "object of id id";
    }   

URI in Jquery

/api/records/1 

Route Configuration

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Attribute routing.
        config.MapHttpAttributeRoutes();

        // Convention-based routing.
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

Review article for more information Attribute routing and onvention-based routing here & this

use google Guava and do it in 2 lines:

import java.util.Map;
import com.google.common.base.Splitter;

public class Parser {
    public static void main(String... args) {
        String uri = "https://google.com.ua/oauth/authorize?client_id=SS&response_type=code&scope=N_FULL&access_type=offline&redirect_uri=http://localhost/Callback";
        String query = uri.split("\\?")[1];
        final Map<String, String> map = Splitter.on('&').trimResults().withKeyValueSeparator('=').split(query);
        System.out.println(map);
    }
}

which gives you

{client_id=SS, response_type=code, scope=N_FULL, access_type=offline, redirect_uri=http://localhost/Callback}

On my machine the Nuget dependency wasn't downloaded correctly, the lib folder inside the nuget package didn't exist, hence the error.

Before

I renamed the Nuget Package in the packages folder and Nuget redownloaded it correctly with the necessary lib folder.

After

Add System.Web.Extensions as a reference to your project

For Ref.

I was experiencing the same issue.. I already had 4 controllers going and working just fine but when I added this one it returned "The requested resource does not support HTTP method 'GET'". I tried everything here and in a couple other relevant articles but was indifferent to the solution since, as Dan B. mentioned in response to the answer, I already had others working fine.

I walked away for a while, came back, and immediately realized that when I added the Controller it was nested under the "Controller" class and not "ApiController" class that my other Controllers were under. I'm assuming I chose the wrong scaffolding option to build the .cs file in Visual Studio. So I included the System.Web.Http namespace, changed the parent class, and everything works without the additional attributes or routing.

ExpandoObject is what are you looking for.

dynamic MyDynamic = new ExpandoObject(); // note, the type MUST be dynamic to use dynamic invoking.
MyDynamic.A = "A";
MyDynamic.B = "B";
MyDynamic.C = "C";
MyDynamic.TheAnswerToLifeTheUniverseAndEverything = 42;

I had the same problem and the "Microsoft.Web.Infrastructure.dll" appeared to be missing. I have tried few advises and installed MVC`s etc. and nothing helped. The solution was to install "Web Services Enhancements (WSE) 1.0 SP1 for Microsoft .NET" which includes Microsoft.Web.Infrastructure.dll. Available at: http://www.microsoft.com/en-gb/download/details.aspx?id=4065

One time, after a power outage, I had to face the same slowness problem each time a breakpoint was hit or a Exception was thrown.

I had the vague remembering that the "suo" file (in the same directory as the "sln" solution file) can be corrupted and make everything slow down.

I deleted my "suo" files and everything was ok. The .suo files deletion is harmless and only implies to recreate my windows layout plus the starting project and a few other non critical customizations.

Though it's probably suggested to get some heavier validation via JS or on the server, HTML5 does support this via the pattern attribute.

<input type= "text" name= "name" pattern= "[0-9]"  title= "Title"/>

Elaborating from DavidG answer which is really near of what is required for a basic solution:

• First, configure the OPTIONSVerbHandler to execute before .Net handlers.

  1. In IIS console, select "Handler Mappings" (either on server level or site level; beware that on site level it will redefine all the handlers for your site and ignore any change done on server level after that; and of course on server level, this could break other sites if they need their own handling of options verb).
  2. In Action pane, select "View ordered list..." Seek OPTIONSVerbHandler, and move it up (lots of clicks...).

  You can also do this in web.config by redefining all handlers under <system.webServer><handlers> (<clear> then <add ...> them back, this is what does the IIS console for you) (By the way, there is no need to ask for "read" permission on this handler.)

• Second, configure custom http headers for your cors needs, such as:

  <system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*"/>
        <add name="Access-Control-Allow-Headers" value="Content-Type"/>
        <add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS"/>
      </customHeaders>
    </httpProtocol>
  </system.webServer>
  

  You can also do this in IIS console.

This is a basic solution since it will send cors headers even on request which does not requires it. But with WCF, it looks like being the simpliest one.

With MVC or webapi, we could instead handle OPTIONS verb and cors headers by code (either "manually" or with built-in support available in latest version of webapi).

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

I found another strange reason and i thought maybe another developer confused as me. I did run install.bat that created to install my service in developer Command Prompt of VS2010 but my service generated in VS2012. it was going to this error and drives me to crazy but i try VS2012 Developer Command Prompt tools and everything gone to be OK. I don't no why but my problem was solved. so you can test it and if anyone know reason of that please share with us. Thanks.

This worked for me but only after forcing the specific verbs to be handled by the default handler.

<system.web>
...
  <httpHandlers>
  ... 
    <add path="*" verb="OPTIONS" type="System.Web.DefaultHttpHandler" validate="true"/>
    <add path="*" verb="TRACE" type="System.Web.DefaultHttpHandler" validate="true"/>
    <add path="*" verb="HEAD" type="System.Web.DefaultHttpHandler" validate="true"/>

You still use the same configuration as you have above, but also force the verbs to be handled with the default handler and validated. Source: http://forums.asp.net/t/1311323.aspx

An easy way to test is just to deny GET and see if your site loads.

Luckily, it’s very easy to resolve. Run the follow command from an elevated command prompt:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If you’re on a 32-bit machine, you may have to use the following:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

I used the following article on MSDN to solve this issue (in this case from MVC 4 to MVC 5)

https://docs.microsoft.com/en-us/aspnet/mvc/overview/releases/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2

Main extracts from the article are:

Main Web.config (Not the one in the Views folder)

In the runtime block update System.Web.Mvc to 5.0.0.0 ,System.Web.Helpers to 3.0.0.0 and System.Web.WebPages to 3.0.0.0

<dependentAssembly>
  <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

<dependentAssembly>
  <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

<dependentAssembly>
  <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

Then look for the appsettings block and update the webpages:Version value to 3.0.0.0

<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
</appSettings>

Views Web.config

Update the host factoryType block to System.Web.Mvc to 5.0.0.0

<system.web.webPages.razor>
   <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
   <pages pageBaseType="System.Web.Mvc.WebViewPage">
      <namespaces>
         <add namespace="System.Web.Mvc" />
      </namespaces>
   </pages>
</system.web.webPages.razor>

Then under the pages block update any references to System.Web.Mvc to 5.0.0.0

    <pages
      validateRequest="false"
      pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
    <controls>
      <add assembly="System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" namespace="System.Web.Mvc" tagPrefix="mvc" />
    </controls>
  </pages>

And finally under the configuration block update the System.Web references to 3.0.0.0

<configuration>
  <configSections>
    <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
      <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
      <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    </sectionGroup>
  </configSections>

Just define your action method like this

public string ThemePath()

and simply return the string itself.

This worked for me too, but with an addition (below).

protected void Page_Load(object sender, EventArgs e) {
  ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
  scriptManager.RegisterPostBackControl(this.btnExcelExport);
  //Further code goes here....
}

I was registering a script on my button to click on another button after its event was finished processing. In order for it to work, I had to remove the other button from the Update Panel (just in case somebody faces the same problem).

System.Web.HttpContext.Current.Server.MapPath("~/") gives null if we call it from a thread.

So, Try to use

System.Web.Hosting.HostingEnvironment.MapPath("~/")

Check the IIS settings. I use IIS 7.5 with 32 or 64 bit compilation within the .NET framework. If you have an app that uses 32-bit mode, make sure to enable the App Pool to be able to use 32-bit instruction. Otherwise, nothing seems to work no matter how much you set the security or strong sign the DLL.

Clean your solution and then set the property of those files to Copy Local = True.

To set the Copy Local property to True or False

In Solution Explorer, click the Show All Files button to display the References node.

• Open the References node for the project.
• Right-click a reference in the References list, and click Properties. The properties associated with that reference appear in a list in the Properties window.
• In the Properties window, change the Copy Local property to True or False.

Is the name of your service class really IService (on the Service namespace)? What you probably had originally was a mismatch in the name of the service class in the name attribute of the <service> element.

I uninstalled ASP.NET MVC 4 using the Windows Control Panel, then reinstalled it by running AspNetMVC4Setup.exe (which I got from https://www.microsoft.com/en-us/download/details.aspx?id=30683), and that fixed the issue for me.

In other words, I didn't need to use Nuget or Visual Studio.

1. Make sure you have System.Web referenced
2. Get rid of the two } at the end.

just remove/ hide the code from create & Edit razor view of your controller.

 @section Scripts {  

   @Scripts.Render("~/bundles/jqueryval")  
 }  

<configuration>
    <system.web>
        <httpRuntime maxRequestLength="1048576" />
    </system.web>
</configuration>

From here.

For IIS7 and above, you also need to add the lines below:

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
   </security>
 </system.webServer>

Dear olga is clear what the message says. Turn off the custom errors to see the details about this error for fix it, and then you close them back. So add mode="off" as:

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Relative answer: Deploying website: 500 - Internal server error

By the way: The error message declare that the web.config is not the one you type it here. Maybe you have forget to upload your web.config ? And remember to close the debug flag on the web.config that you use for online pages.

You can throw a HttpResponseException

HttpResponseMessage response = 
    this.Request.CreateErrorResponse(HttpStatusCode.BadRequest, "your message");
throw new HttpResponseException(response);

This can happen if you call

 .SingleOrDefault() 

on an IEnumerable with 2 or more elements.

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

Referring to the answers above, I am only adding this to help clarify things. It is possible to use HttpClient from .Net 4.0, and you have to install the package from here

However, the text is very confusion and contradicts itself.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, or Windows Phone 8.1 when consuming a library that uses this package.

But underneath it states that these are the supported platforms.

Supported Platforms:

• .NET Framework 4

• Windows 8

• Windows Phone 8.1

• Windows Phone Silverlight 7.5

• Silverlight 4

• Portable Class Libraries

Ignore what it ways about targeting .Net 4.5. This is wrong. The package is all about using HttpClient in .Net 4.0. However, you may need to use VS2012 or higher. Not sure if it works in VS2010, but that may be worth testing.

I needed to change the SSL settings on a subfolder when i got this nice message. In my case following action helped me out.

Opened C:\Windows\System32\inetsrv\config\applicationHost.config

And changed the value from overrideModeDefault="Deny" to "Allow"

<sectionGroup name="system.webServer">
 ...
    <sectionGroup name="security">
        <section name="access" overrideModeDefault="Allow" />
    </sectionGroup>

Use the Controller's Redirect() method.

public ActionResult YourAction()
{
    // ...
    return Redirect("http://www.example.com");
}

Update

You can't directly perform a server side redirect from an ajax response. You could, however, return a JsonResult with the new url and perform the redirect with javascript.

public ActionResult YourAction()
{
    // ...
    return Json(new {url = "http://www.example.com"});
}

$.post("@Url.Action("YourAction")", function(data) {
    window.location = data.url;
});

Try this webconfg.. replace "NewsApi.dll" with your main dll!

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\NewsApi.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
    </system.webServer>
  </location>
</configuration>

How I solved it.

1. Open project (!) "Properties", choose "Application", select targeting framework ".Net Framework 4.5"
2. Right click on your project -> Add reference
3. Make sure that in "Assemblies" -> "Extensions" option "System.Net.Http" is unchecked
4. Go to "Assemblies" -> "Framework" and select "System.Net.Http" and "System.Net.Http" options
5. That`s all!

In my case i had at the beginning .Net 4.0 and "Assemblies" -> "Extensions" option "System.Net.Http" with version 2.0.0.0. After my actions "Assemblies" -> "Framework" options "System.Net.Http" and "System.Net.Http" had the same 4.0.0.0 version.

I was looking at this issue as well, and in my case the solution was too easy. I added a new empty project to the solution. The newly added project is automatically set as a console application. But since the project added was a 'empty' project, no Program.cs existed in that new project. (As expected)

All I needed to do was change the output type of the project properties to Class library

You should use the Server.HtmlEncode method to protect your site from dangerous input.

Thanks for this post. I got this worked for using mustache templates in my asp.net mvc project I used the following, and it worked for me.

<system.webServer>   
  <staticContent>
   <mimeMap fileExtension=".mustache" mimeType="text/html"/>
  </staticContent>
</system.WebServer>

It is clear from the error.

The HtmlHelpers appended with "For" expects lambda expression as a parameter.

If you are passing the value directly, better use Normal one.

e.g.

Instead of TextboxFor(....) use Textbox()

syntax for TextboxFor will be like Html.TextBoxFor(m=>m.Property)

In your scenario you can use basic for loop, as it will give you index to use.

@for(int i=0;i<Model.Theme.Count;i++)
 {
   @Html.LabelFor(m=>m.Theme[i].name)
   @for(int j=0;j<Model.Theme[i].Products.Count;j++) )
     {
      @Html.LabelFor(m=>m.Theme[i].Products[j].name)
      @for(int k=0;k<Model.Theme[i].Products[j].Orders.Count;k++)
          {
           @Html.TextBoxFor(m=>Model.Theme[i].Products[j].Orders[k].Quantity)
           @Html.TextAreaFor(m=>Model.Theme[i].Products[j].Orders[k].Note)
           @Html.EditorFor(m=>Model.Theme[i].Products[j].Orders[k].DateRequestedDeliveryFor)
      }
   }
}

Somebody posted quite a few form fields to your page. The new default max introduced by the recent security update is 1000.

Try adding the following setting in your web.config's <appsettings> block. in this block you are maximizing the MaxHttpCollection values this will override the defaults set by .net Framework. you can change the value accordingly as per your form needs

<appSettings>
    <add key="aspnet:MaxHttpCollectionKeys" value="2001" />
 </appSettings>

A new option is Jexus Manager for IIS Express,

https://blog.lextudio.com/2014/10/jexus-manager-for-iis-express/

It is just the management tool you know how to use.

I have issue with large calculation in sp_foo that take large time so i fixed
with this little bit code

public partial class FooEntities : DbContext
{
   public FooEntities()
         : base("name=FooEntities")
    {
        this.Configuration.LazyLoadingEnabled = false;

        // Get the ObjectContext related to this DbContext
        var objectContext = (this as IObjectContextAdapter).ObjectContext;

        // Sets the command timeout for all the commands
        objectContext.CommandTimeout = 380;
    }

To make Visual Studio adding 3rd party assembly or even your own assembly from other project in solution to GAC please do next:

1. Open Package.package from Package folder in SharePoint project.

2. Click Advanced in bottom area.

3. Click Add and chose which type of assembly you want to add.

4. In dialog select dll file, chec GAC or BIN, add safe controls and class resources entries if required. Click Ok.

Your assembly will be packaged to WSP, defined in manifest and deployed everytime.

When you install this nuget package Microsoft.AspNet.WebPages they can be find in C:\Program Files (x86)\Microsoft Visual Studio\Shared\Packages\Microsoft.AspNet.WebPages.x.x.x\lib\net45

I realize the question might be rather old, but you say the backend is running on the same server. That means on a different port, probably other than the default port 80.

I've read that when you use the "connectionManagement" configuration element, you need to specify the port number if it differs from the default 80.

LINK: maxConnection setting may not work even autoConfig = false in ASP.NET

Secondly, if you choose to use the default configuration (address="*") extended with your own backend specific value, you might consider putting the specific value first! Otherwise, if a request is made, the * matches first and the default of 2 connections is taken. Just like when you use the section in web.config.

LINK: <remove> Element for connectionManagement (Network Settings)

Hope it helps someone.

I realize this is a rather late post but still a possible solution for the OP. I use IE9 on Win 7 and have been having Adobe Reader's grey screen issues for several months when trying to open pdf bank and credit card statements online. I could open everything in Firefox or Opera but not IE. I finally tried PDF-Viewer, set it as the default pdf viewer in its preferences and no more problems. I'm sure there are other free viewers out there, like Foxit, PDF-Xchange, etc., that will give better results than Reader with less headaches. Adobe is like some of the other big companies that develop software on a take it or leave it basis ... so I left it.

Add on top page

protected void Page_Load(object sender, EventArgs e)
{    
    if (!Page.IsPostBack)
    {
        //Code display data
    }
}

IIS7 defines a defaultDocument section in its configuration files which can be found in the %WinDir%\System32\InetSrv\Config folder. Most likely, the file index.aspx is already defined as a default document in one of IIS7's configuration files and you are adding it again in your web.config.

I suspect that removing the line <add value="index.aspx" />

from the defaultDocument/files section will fix your issue.

The defaultDocument section of your config will look like:

<defaultDocument>
  <files>
    <remove value="default.aspx" />
    <remove value="index.html" />
    <remove value="iisstart.htm" />
    <remove value="index.htm" />
    <remove value="Default.asp" />
    <remove value="Default.htm" />
  </files>
</defaultDocument>

Note that index.aspx will still appear in the list of default documents for your site in the IIS manager.

Looking at the controller, and learing a bit more about how MVC actually works, I was able to make sense of this.

My view was one of the auto-generated ones, and contained this line of code:

@Html.DropDownList("PriorityID", string.Empty)

To add html attributes, I needed to do something like this:

@Html.DropDownList("PriorityID", (IEnumerable<SelectListItem>)ViewBag.PriorityID, new { @class="dropdown" })

Thanks again to @Laurent for your help, I realise the question wasn't as clear as it could have been...

UPDATE:

A better way of doing this would be to use DropDownListFor where possible, that way you don't rely on a magic string for the name attribute

@Html.DropDownListFor(x => x.PriorityID, (IEnumerable<SelectListItem>)ViewBag.PriorityID, new { @class = "dropdown" })

This line (top of the stack trace) is telling you there is something wrong which the hosting configuration.

 System.Web.HttpRuntime.HostingInit(HostingEnvironmentFlags hostingFlags, PolicyLevel policyLevel, Exception appDomainCreationException) +336

How is your server set up? Have you checked the config files?

I'd search through them specifically for any settings or attributes which have the single value "/".

You shouldn't be calling .ToString().

As the error message clearly states, you're writing a conditional in which one half is an IHtmlString and the other half is a string.
That doesn't make sense, since the compiler doesn't know what type the entire expression should be.

There is never a reason to call Html.Raw(...).ToString().
Html.Raw returns an HtmlString instance that wraps the original string.
The Razor page output knows not to escape HtmlString instances.

However, calling HtmlString.ToString() just returns the original string value again; it doesn't accomplish anything.

You can use another option which is the Newtonsoft.Json, you can install it from NuGet Package Manager.

Tools >> Nuget Package Manager >> Package Manager Console by issuing command

Install-Package Newtonsoft.Json

or

by using the GUI at Tools >> Nuget Package Manager >> Manage NuGet Packages for Solution...

Html.RenderPartial() is a void method - you can check whether a method is a void method by placing your mouse over the call to RenderPartial in your code and you will see the text (extension) void HtmlHelper.RenderPartial...

Void methods require a semicolon at the end of the calling code.

In the Webforms view engine you would have encased your Html.RenderPartial() call within the bee stings <% %>

like so

<% Html.RenderPartial("Path/to/my/partial/view"); %>

when you are using the Razor view engine the equivalent is

@{Html.RenderPartial("Path/to/my/partial/view");}

Put the identity element before the authentication element

I had a similer problem with SqlClient on WCF service. My solution was to put that lines in client app.config

  <startup>
     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
  </startup>

Hopes it helps for someone..

OK, after days struggling with this issue, I finally fixed it.

• Not by clearing ASP.NET temp
• Not by reinstalling the .NET framework!

Simple!

• I changed the application pool identity from "Local system" to "ApplicationPoolIdentity"

Apparently there was a permission error with my local system that the C# compiler (csc.exe) could not access some resources and source codes.

In order to change your AppPool identity follow steps given here: http://learn.iis.net/page.aspx/624/application-pool-identities/

Found this article on net, very relevant to this topic. So posting here.

ASP.NET Internals - Clearing ASP.NET Session variables

In VB.NET, you need to use the GetType method to retrieve the type of an instance of an object, and the GetType() operator to retrieve the type of another known type.

Once you have the two types, you can simply compare them using the Is operator.

So your code should actually be written like this:

Sub FillCategories(ByVal Obj As Object)
    Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
    cmd.CommandType = CommandType.StoredProcedure
    Obj.DataSource = cmd.ExecuteReader
    If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then

    End If
    Obj.DataBind()
End Sub

You can also use the TypeOf operator instead of the GetType method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:

If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then

End If

Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.

Changing my header to the following solve the problem:

<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

dynDiv.Attributes["class"] = "myCssClass";

Just after your Page_Load add this:

public override void VerifyRenderingInServerForm(Control control)
{
    //base.VerifyRenderingInServerForm(control);
}

Note that I don't do anything in the function.

EDIT: Tim answered the same thing. :) You can also find the answer Here

Use these tools for generating a C# class, and then use this code to serialize your object:

 var json = new JavaScriptSerializer().Serialize(obj);

Try changing it to static class and back. That might resolve visual studio complaining when it's a false positive.

Check the below lines are present in your web.config file

<system.web> <httpRuntime requestPathInvalidCharacters="" /> </system.web>

This wont necessarily fix the problem...but it will tell you what the real problem is.
Its currently trying to use a custom error page that doesn't exist.
If you add this line to Web.config (under system.web tag) it should give you the real error.

<system.web>
    <!-- added line -->
    <customErrors mode="Off"/>
    <!-- added  line -->
</system.web>

The quotes around type="text/javascript" are ending your string before you want to. Use single quotes inside to avoid this problem.

Use this

 type='text/javascript'

To make the transform work in development (using F5 or CTRL + F5) I drop ctt.exe (https://ctt.codeplex.com/) in the packages folder (packages\ConfigTransform\ctt.exe).

Then I register a pre- or post-build event in Visual Studio...

$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)connectionStrings.config" transform:"$(ProjectDir)connectionStrings.$(ConfigurationName).config" destination:"$(ProjectDir)connectionStrings.config"
$(SolutionDir)packages\ConfigTransform\ctt.exe source:"$(ProjectDir)web.config" transform:"$(ProjectDir)web.$(ConfigurationName).config" destination:"$(ProjectDir)web.config"

For the transforms I use SlowCheeta VS extension (https://visualstudiogallery.msdn.microsoft.com/69023d00-a4f9-4a34-a6cd-7e854ba318b5).

Just a quick note. It is DbContext, not DBContext. i.e. with a lowercase 'B'. I discovered this because I had the same problem while intelesense was not working until I tried typing the full name space System.Data.Entity... and name and finally it suggested the lowercase 'b' option:-

System.Data.Entity.DbContext

Alternative ASP.NET MVC 5 Fix:

In my case the error was occurring during the request. Best approach in my scenario is modifying the actual JsonValueProviderFactory which applies the fix to the global project and can be done by editing the global.cs file as such.

JsonValueProviderConfig.Config(ValueProviderFactories.Factories);

add a web.config entry:

<add key="aspnet:MaxJsonLength" value="20971520" />

and then create the two following classes

public class JsonValueProviderConfig
{
    public static void Config(ValueProviderFactoryCollection factories)
    {
        var jsonProviderFactory = factories.OfType<JsonValueProviderFactory>().Single();
        factories.Remove(jsonProviderFactory);
        factories.Add(new CustomJsonValueProviderFactory());
    }
}

This is basically an exact copy of the default implementation found in System.Web.Mvc but with the addition of a configurable web.config appsetting value aspnet:MaxJsonLength.

public class CustomJsonValueProviderFactory : ValueProviderFactory
{

    /// <summary>Returns a JSON value-provider object for the specified controller context.</summary>
    /// <returns>A JSON value-provider object for the specified controller context.</returns>

I had this issue on the DBContext. Got the error when I tried run an update-database in Package Manager console to add a migration:

public virtual IDbSet Status { get; set; }

The problem was that the type and the name were the same. I changed it to:

public virtual IDbSet Statuses { get; set; }

I had the same problem when I tried to share the site root folder with another user. Some folder lost the permission. So I followed the steps to add permission to IIS_IUSRS group as suggested by Afshin Gh. The problem is this group was not available for me. I am using windows 7.

What I did I just changed some steps:

1. Right click on the parent folder (who lost the permission),
2. Properties => Security =>In "Group or user names:",
3. Click Edit...
4. Window "Permission for your folder" will be opened.
5. In "Group or user names:" press ADD... btn,
6. Type Authen and press Check Names,
7. You will see the complete group name "Authenticated Users"
8. Press ok => apply.
9. This should enable privileges again.

That worked for me.

One can reproduce the error with the code below:

public ActionResult ClosingTheConnectionAction(){
   try
   {
      //we need to set buffer to false to
      //make sure data is written in chunks
      Response.Buffer = false;  
      var someText = "Some text here to make things happen ;-)";
      var content = GetBytes( someText );

      for(var i=0; i < 100; i++)
      {
         Response.OutputStream.Write(content, 0, content.Length);
      }

      return View();
   }
   catch(HttpException hex)
   {
      if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
            {
                //react on remote host closed the connection exception.
                var msg = hex.Message;
            }  
   }
   catch(Exception somethingElseHappened)
   {
      //handle it with some other code
   }

   return View();
} 

Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)

I had the same problem cause the user (Identity) that I used in the application pool was not belowing to IIS_IUSRS group. Added the user to the group and everything work

My solution:

UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext(ContextType.Domain, myDomain), IdentityType.SamAccountName, myUser);
List<string> UserADGroups = new List<string>();            
foreach (GroupPrincipal group in user.GetGroups())
{
    UserADGroups.Add(group.ToString());
}

It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1 is null or ConfigurationManager.AppSettings.Get("Url") is returning null.

I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.

This can be another way to do it and validate nulls

DataControlField dataControlField = UsersGrid.Columns.Cast<DataControlField>().SingleOrDefault(x => x.HeaderText == "Email");
            if (dataControlField != null)
                dataControlField.Visible = false;

If none of the answers helps, you might need to adjust the project properties. Check this other StackOverflow answer on how to do that:

EDIT:

The info below is only applicable to VS2008 and the 3.5 framework. VS2010 has a new registry location. Further details can be found on MSDN: How to Add or Remove References in Visual Studio.

ORIGINAL

It should be listed in the .NET tab of the Add Reference dialog. Assemblies that appear there have paths in registry keys under:

HKLM\Software\Microsoft\.NETFramework\AssemblyFolders\

I have a key there named Microsoft .NET Framework 3.5 Reference Assemblies with a string value of:

C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\

Navigating there I can see the actual System.Web.Extensions dll.

EDIT:

I found my .NET 4.0 version in:

C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.Web.Extensions.dll

I'm running Win 7 64 bit, so if you're on a 32 bit OS drop the (x86).

This answer from Roy Tinker here:

var date = new Date(parseInt(jsonDate.substr(6)));

As he says: The substr function takes out the "/Date(" part, and the parseInt function gets the integer and ignores the ")/" at the end. The resulting number is passed into the Date constructor.

Another option is to simply format your information properly on the ASP side such that JavaScript can easily read it. Consider doing this for your dates:

DateTime.Now()

Which should return a format like this:

7/22/2008 12:11:04 PM

If you pass this into a JavaScript Date constructor like this:

var date = new Date('7/22/2008 12:11:04 PM');

The variable date now holds this value:

Tue Jul 22 2008 12:11:04 GMT-0700 (Pacific Daylight Time)

Naturally, you can format this DateTime object into whatever sort of string/int the JS Date constructor accepts.

Just wanted to point out one thing missing in LazyOne's answer (I would have just commented under the answer but don't have enough rep)

In rule #2 for permanent redirect there is thing missing:

redirectType="Permanent"

So rule #2 should look like this:

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" redirectType="Permanent" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Edit

For more information on how to use the URL Rewrite Module see this excellent documentation: URL Rewrite Module Configuration Reference

In response to @kneidels question from the comments; To match the url: topic.php?id=39 something like the following could be used:

<system.webServer>
  <rewrite>
    <rules>
      <rule name="SpecificRedirect" stopProcessing="true">
        <match url="^topic.php$" />
        <conditions logicalGrouping="MatchAll">
          <add input="{QUERY_STRING}" pattern="(?:id)=(\d{2})" />
        </conditions>
        <action type="Redirect" url="/newpage/{C:1}" appendQueryString="false" redirectType="Permanent" />
      </rule>
    </rules>
  </rewrite>
</system.webServer>

This will match topic.php?id=ab where a is any number between 0-9 and b is also any number between 0-9. It will then redirect to /newpage/xy where xy comes from the original url. I have not tested this but it should work.

For example in my case I accidentaly changed role of some users to incorrect, and my application got error during starting (NullReferenceException). When I fixed it - the app starts fine.

I'm assuming c++ here. If you're using c#, the answer is probably the same, but the syntax will be a bit different. The enum is a set of int values. It's not an object, so you shouldn't be setting it to null. Setting something to null means you are pointing a pointer to an object to address zero. You can't really do that with an int. What you want to do with an int is to set it to a value you wouldn't normally have it at so that you can tel if it's a good value or not. So, set your colour to -1

Color color = -1;

Or, you can start your enum at 1 and set it to zero. If you set the colour to zero as it is right now, you will be setting it to "red" because red is zero in your enum.

So,

enum Color {
red =1
blue,
green
}
//red is 1, blue is 2, green is 3
Color mycolour = 0;

Check if there is any conflict in your IIS authentication. i.e. you enable the anonymous authentication and ASP.NET impersonation both might cause the error also.

In my case use VS 2013, and It's not support MVC 3 natively (even of you change ./Views/web.config): https://stackoverflow.com/a/28155567/1536197

Instead of casting the model in the RenderPartial call, and since you're using razor, you can modify the first line in your view from

@model dynamic

to

@model YourNamespace.YourModelType

This has the advantage of working on every @Html.Partial call you have in the view, and also gives you intellisense for the properties.

System.Net.WebUtility.HtmlDecode

Try HostingEnvironment.MapPath, which is static.

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?

What if:

 <asp:Button ID="Button1" runat="server" CssClass="test1 test3 test-test" />

To add or remove a class, instead of overwriting all classes with

   BtnventCss.CssClass = "hom_but_a"

keep the HTML correct:

    string classname = "TestClass";

    // Add a class
    BtnventCss.CssClass = String.Join(" ", Button1
               .CssClass
               .Split(' ')
               .Except(new string[]{"",classname})
               .Concat(new string[]{classname})
               .ToArray()
       );

     // Remove a class
     BtnventCss.CssClass = String.Join(" ", Button1
               .CssClass
               .Split(' ')
               .Except(new string[]{"",classname})
               .ToArray()
       );

This assures

• The original classnames remain.
• There are no double classnames
• There are no disturbing extra spaces

Especially when client-side development is using several classnames on one element.

In your example, use

   string classname = "TestClass";

    // Add a class
    Button1.Attributes.Add("class", String.Join(" ", Button1
               .Attributes["class"]
               .Split(' ')
               .Except(new string[]{"",classname})
               .Concat(new string[]{classname})
               .ToArray()
       ));

     // Remove a class
     Button1.Attributes.Add("class", String.Join(" ", Button1
               .Attributes["class"]
               .Split(' ')
               .Except(new string[]{"",classname})
               .ToArray()
       ));

You should wrap this in a method/property ;)

I had the same issue and wasn't able to locate the System.Web.MVC reference assembly.

Finally found out and it was located inside the following location.

Note if your VS was installed in C: (Sometimes the MVC.dll is not in the default location which everybody talk about, i mean the "Reference Assemblies" folder located in the C: drive.)

if its not there, it should definitely be in here:

\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll

So add the dll through navigating or the browse tab in the add reference menu.

Set the application pool to 2.0, I did it and worked.

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

I found it to be pretty nice to do it like this (usage in the view):

    @Html.HiddenJsonFor(m => m.TrackingTypes)

Here is the according helper method Extension class:

public static class DataHelpers
{
    public static MvcHtmlString HiddenJsonFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression)
    {
        return HiddenJsonFor(htmlHelper, expression, (IDictionary<string, object>) null);
    }

    public static MvcHtmlString HiddenJsonFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        return HiddenJsonFor(htmlHelper, expression, HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes));
    }

    public static MvcHtmlString HiddenJsonFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, IDictionary<string, object> htmlAttributes)
    {
        var name = ExpressionHelper.GetExpressionText(expression);
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);

        var tagBuilder = new TagBuilder("input");
        tagBuilder.MergeAttributes(htmlAttributes);
        tagBuilder.MergeAttribute("name", name);
        tagBuilder.MergeAttribute("type", "hidden");

        var json = JsonConvert.SerializeObject(metadata.Model);

        tagBuilder.MergeAttribute("value", json);

        return MvcHtmlString.Create(tagBuilder.ToString());
    }
}

It is not super-sofisticated, but it solves the problem of where to put it (in Controller or in view?) The answer is obviously: neither ;)

In my case it was:

Persist Security Info=True;

in my connection string that needed to be removed. Once I did that I no longer had issues.

First things first, if the date property is storing a date, store it using a DateTime. If you parse the date through the sort you have to parse it for each item being compared, that's not very efficient...

You can then make an IComparer:

public class TagComparer : IComparer<cTag>
{
    public int Compare(cTag first, cTag second)
    {
        if (first != null && second != null)
        {
            // We can compare both properties.
            return first.date.CompareTo(second.date);
        }

        if (first == null && second == null)
        {
            // We can't compare any properties, so they are essentially equal.
            return 0;
        }

        if (first != null)
        {
            // Only the first instance is not null, so prefer that.
            return -1;
        }

        // Only the second instance is not null, so prefer that.
        return 1;
    }
}

var list = new List<cTag>();
// populate list.

list.Sort(new TagComparer());

You can even do it as a delegate:

list.Sort((first, second) =>
          {
              if (first != null && second != null)
                  return first.date.CompareTo(second.date);

              if (first == null && second == null)
                  return 0;

              if (first != null)
                  return -1;

              return 1;
          });

1) When the user logs out (Forms signout in Action) I want to redirect to a login page.

public ActionResult Logout() {
    //log out the user
    return RedirectToAction("Login");
}

2) In a Controller or base Controller event eg Initialze, I want to redirect to another page (AbsoluteRootUrl + Controller + Action)

Why would you want to redirect from a controller init?

the routing engine automatically handles requests that come in, if you mean you want to redirect from the index action on a controller simply do:

public ActionResult Index() {
    return RedirectToAction("whateverAction", "whateverController");
}

If you have a JSON string and want to "prettify" it, but don't want to serialise it to and from a known C# type then the following does the trick (using JSON.NET):

using System;
using System.IO;
using Newtonsoft.Json;

class JsonUtil
{
    public static string JsonPrettify(string json)
    {
        using (var stringReader = new StringReader(json))
        using (var stringWriter = new StringWriter())
        {
            var jsonReader = new JsonTextReader(stringReader);
            var jsonWriter = new JsonTextWriter(stringWriter) { Formatting = Formatting.Indented };
            jsonWriter.WriteToken(jsonReader);
            return stringWriter.ToString();
        }
    }
}

Although I have attended the above, I have come to this point after many attempts. 1- If you want access to the certificate from the store, you can do this as an example 2- It is much easier and cleaner to produce the certificate and use it via a path

EventHandler handler = (s, e) => MessageBox.Show("Woho");

button.Click += handler;

Here dataTpe is "json" so, data/reqParam must be in the form of string while calling API, many as much as object as you want but at last inside $.ajax's data stringify the object.

             let person= {  name: 'john',
                age: 22
            };

           var personStr = JSON.stringify(person); 

            $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: JSON.stringify( { param1: personStr } ),
                contentType: "application/json;charset=utf-8",
                dataType: "json",
        success: function (response) {

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

OR,

       $.ajax({
                url: "@Url.Action("METHOD", "CONTROLLER")",
                type: "POST",
                data: personStr,

            console.log("Success");

        },
        error: function (error) {
            console.log("error found",error);
        }
    });

You're probably targeting the Client Profile, in which System.Web.dll is not available.

You can target the full framework in project's Properties.

I'll broadly agree with Vagrant on the cause:

1. your action was executing, writing markup to response stream
2. the stream was unbuffered forcing the response headers to get written before the markup writing could begin.
3. Your view encountered a runtime error
4. Exception handler kicks in trying to set the status code to something else non-200
5. Fails because the headers have already been sent.

Where I disagree with Vagrant is the "cause no errors in binding" remedy - you could still encounter runtime errors in View binding e.g. null reference exceptions.

A better solution for this is to ensure that Response.BufferOutput = true; before any bytes are sent to the Response stream. e.g. in your controller action or On_Begin_Request in application. This enables server transfers, cookies/headers to be set etc. right the way up to naturally ending response, or calling end/flush.

Of course also check that buffer isn't being flushed/set to false further down in the stack too.

MSDN Reference: HttpResponse.BufferOutput

You would use an MvcHtmlString if you want to pass raw HTML to an MVC helper method and you don't want the helper method to encode the HTML.

You can use ~/img/myImage.png instead of ../img/myImage.png to avoid this error in ASP.NET pages.

Old Question, but still, if it might help someone, here is complete sample

<form id="form1" runat="server">
    <div>
        <asp:FileUpload ID="FileUpload1" runat="server" /><br/>
        <asp:Button ID="Button1" runat="server" Text="Upload File" OnClick="UploadFile" /><br/>
        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>
    </div>
</form>

In your Code-behind, C# code to grab file and save it in Directory

protected void UploadFile(object sender, EventArgs e)
    {
        //folder path to save uploaded file
        string folderPath = Server.MapPath("~/Upload/");

        //Check whether Directory (Folder) exists, although we have created, if it si not created this code will check
        if (!Directory.Exists(folderPath))
        {
            //If folder does not exists. Create it.
            Directory.CreateDirectory(folderPath);
        }

       //save file in the specified folder and path
        FileUpload1.SaveAs(folderPath + Path.GetFileName(FileUpload1.FileName));

        //once file is uploaded show message to user in label control
        Label1.Text = Path.GetFileName(FileUpload1.FileName) + " has been uploaded.";
    }

Source: File Upload in ASP.NET (Web-Forms Upload control example)

You can do it on a per file basis. Use the path attribute to include the filename

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <location path="YourFileNameHere.xml">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="DisableCache" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

If you have python, you can use a package called iis_bridge that solves the problem. To install:

pip install iis_bridge

then in the python console:

import iis_bridge as iis
iis.install()

For me I had all of the namespaces on the pages and none of the solutions above fixed it. My problem was in:

<%@ Page Language="C#" 
AutoEventWireup="true" 
CodeBehind="xxx.aspx.cs" 
Inherits="xxx.xxx.xxx" 
MasterPageFile="~masterurl/default.master" %>

Then in my aspx.cs file the namespace did not match the Inherits tag. So it needed

namespace xxx.xxx.xxx

In the .cs to match the Inherits.

I had the same issue in Windows 7.

The solution was to go to basic settings > connect as > specific user - and log in as a user, instead of the default 'pass-through'

This fixed the issue for me.

I think is a bug in MVC. I struggled with this issue for hours today.

Given this:

public ViewResult SomeAction(SomeModel model) 
{
    model.SomeString = "some value";
    return View(model); 
}

The view renders with the original model, ignoring the changes. So I thought, maybe it does not like me using the same model, so I tried like this:

public ViewResult SomeAction(SomeModel model) 
{
    var newModel = new SomeModel { SomeString = "some value" };
    return View(newModel); 
}

And still the view renders with the original model. What's odd is, when I put a breakpoint in the view and examine the model, it has the changed value. But the response stream has the old values.

Eventually I discovered the same work around that you did:

public ViewResult SomeAction(SomeModel model) 
{
    var newModel = new SomeModel { SomeString = "some value" };
    ModelState.Clear();
    return View(newModel); 
}

Works as expected.

I don't think this is a "feature," is it?

I had the similar problem. This is my solution : Put isolated classes which require property [Build Action] set as [Compile] to any folder other than App_Code like Application_Code since the App_Code folder will be compiled as a separate assembly, having the same Class compiled in 2 assemblies.

How to Fix “HTTP Error 403.14 – Forbidden The Web server is configured to not list the contents of this directory”

This error occurs when you have MVC 2+ running hosted on IIS 7+, this is because ASP.NET 4 was not registered in IIS. In my case I was creating a MVC 3 project and hosting it on IIS 7.5.

To fix it, make sure you have MVC 2 or above and .Net Framework 4.0 installed, then run a command prompt as administrator and type the following line:

32bit (x86)

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

64bit (x64)

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir

sn -T <assembly> in Visual Studio command line. If an assembly is installed in the global assembly cache, it's easier to go to C:\Windows\assembly and find it in the list of GAC assemblies.

On your specific case, you might be mixing type full name with assembly reference, you might want to take a look at MSDN.

I have tried almost all the answers from below list, but did not work for me. But read the exception well and then tried rename my Dbset name TransactionsModel to Transactions and it work for me.

old Code:

public class MyContext : DbContext
    {
        //....
        public DbSet<Models.TransactionsModel> TransactionsModel { get; set; }
    }

New Code:

public class MyContext : DbContext
    {
        //....
        public DbSet<Models.TransactionsModel> Transactions { get; set; }
    }

Manual load related System.Data.SQLite assembly can resolve this.

Changed gatapia's Code as below:

    public static void LoadSQLLiteAssembly()
    {
        Uri dir = new Uri(Assembly.GetExecutingAssembly().CodeBase);
        FileInfo fi = new FileInfo(dir.AbsolutePath);
        string appropriateFile = Path.Combine(fi.Directory.FullName, GetAppropriateSQLLiteAssembly());
        Assembly.LoadFrom(appropriateFile);
    }

    private static string GetAppropriateSQLLiteAssembly()
    {
        string pa = Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE");
        string arch = ((String.IsNullOrEmpty(pa) || String.Compare(pa, 0, "x86", 0, 3, true) == 0) ? "32" : "64");
        return "System.Data.SQLite.x" + arch + ".DLL";
    }

You probably need something like:

result.className = 'red'; 

In pure JavaScript you should use className to deal with classes. jQuery has an abstraction called addClass for it.

If, like me, you struggled to find an example that uses headers with basic authentication and the rest template exchange API, this is what I finally worked out...

private HttpHeaders createHttpHeaders(String user, String password)
{
    String notEncoded = user + ":" + password;
    String encodedAuth = Base64.getEncoder().encodeToString(notEncoded.getBytes());
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.add("Authorization", "Basic " + encodedAuth);
    return headers;
}

private void doYourThing() 
{
    String theUrl = "http://blah.blah.com:8080/rest/api/blah";
    RestTemplate restTemplate = new RestTemplate();
    try {
        HttpHeaders headers = createHttpHeaders("fred","1234");
        HttpEntity<String> entity = new HttpEntity<String>("parameters", headers);
        ResponseEntity<String> response = restTemplate.exchange(theUrl, HttpMethod.GET, entity, String.class);
        System.out.println("Result - status ("+ response.getStatusCode() + ") has body: " + response.hasBody());
    }
    catch (Exception eek) {
        System.out.println("** Exception: "+ eek.getMessage());
    }
}

Being consistent is important, but this is the question to ask yourself: "Do I have a constructor for anything else?"

Typically, I am creating models for data transfers that the class itself does nothing except work as housing for variables.

In these scenarios, I usually don't have any methods or constructors. It would feel silly to me to create a constructor for the exclusive purpose of initializing my lists, especially since I can initialize them in-line with the declaration.

So as many others have said, it depends on your usage. Keep it simple, and don't make anything extra that you don't have to.

WARNING: git clean -f will remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.

Try this and see git clean -f.

git reset --hard will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under Git tracking.

Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)

• git clean -df
• git clean -xdf CAUTION! This will also delete ignored files

Support for single character marker labels was added to Google Maps in version 3.21 (Aug 2015). See the new marker label API.

You can now create your label marker like this:

var marker = new google.maps.Marker({
  position: new google.maps.LatLng(result.latitude, result.longitude), 
  icon: markerIcon,
  label: {
    text: 'A'
  }
});

If you would like to see the 1 character restriction removed, please vote for this issue.

Update October 2016:

This issue was fixed and as of version 3.26.10, Google Maps natively supports multiple character labels in combination with custom icons using MarkerLabels.

Use this

<div *ngFor="let talk of talks> 
   {{talk.title}} 
   {{talk.speaker}}
   <p>{{talk.description}} 
</div>

You need to specify variable to iterate over an array of an object

I think that your problem is in the location of the image. You shall place it in your source, and then use it like this:

  JButton button = new JButton();
  try {
    Image img = ImageIO.read(getClass().getResource("resources/water.bmp"));
    button.setIcon(new ImageIcon(img));
  } catch (Exception ex) {
    System.out.println(ex);
  }

In this example, it is assumed that image is in src/resources/ folder.

In addition to qqplots and the Shapiro-Wilk test, the following methods may be useful.

Qualitative:

• histogram compared to the normal
• cdf compared to the normal
• ggdensity plot
• ggqqplot

Quantitative:

• nortest package normality tests
• normtest package normality tests

The qualitive methods can be produced using the following in R:

library("ggpubr")
library("car")

h <- hist(data, breaks = 10, density = 10, col = "darkgray") 
xfit <- seq(min(data), max(data), length = 40) 
yfit <- dnorm(xfit, mean = mean(data), sd = sd(data)) 
yfit <- yfit * diff(h$mids[1:2]) * length(data) 
lines(xfit, yfit, col = "black", lwd = 2)

plot(ecdf(data), main="CDF")
lines(ecdf(rnorm(10000)),col="red")

ggdensity(data)

ggqqplot(data)

A word of caution - don't blindly apply tests. Having a solid understanding of stats will help you understand when to use which tests and the importance of assumptions in hypothesis testing.

As discussed above, we need to implement Select Class in Selenium and further we can use various available methods like :-

Just note to use the last_working_commit_id, when reverting a non-working commit

git reset --hard <last_working_commit_id>

So we must not reset to the commit_id that we don't want.

Then sure, we must push to remote branch:

git push --force

This will work. Link to your SVG using the following pattern:

https://cdn.rawgit.com/<repo-owner>/<repo>/<branch>/path/to.svg

The downside is hardcoding the owner and repo in the path, meaning the svg will break if either of those are renamed.

You can use JavaScript:

<script type ="text/javascript">
 function WriteToFile(passForm) {

    set fso = CreateObject("Scripting.FileSystemObject");  
    set s = fso.CreateTextFile("C:\test.txt", True);
    s.writeline(document.passForm.input1.value);
    s.writeline(document.passForm.input2.value);
    s.writeline(document.passForm.input3.value);
    s.Close();
 }
  </script>

If this does not work, an alternative is the ActiveX object:

<script type = "text/javascript">
function WriteToFile(passForm)
{
var fso = new ActiveXObject("Scripting.FileSystemObject");
var s = fso.CreateTextFile("C:\\Test.txt", true);
s.WriteLine(document.passForm.input.value);
s.Close();
}
</script>

Unfortunately, the ActiveX object, to my knowledge, is only supported in IE.

Your problem is:

for line in p.stdout:
    print(">>> " + str(line.rstrip()))
    p.stdout.flush()

the iterator itself has extra buffering.

Try doing like this:

while True:
  line = p.stdout.readline()
  if not line:
     break
  print line

That depends on the nature of the information you want to return.

If it is a single integer value, you can use the return statement

 create proc myproc
 as 
 begin
     return 1
 end
 go
 declare @i int
 exec @i = myproc

If you have a non integer value, or a number of scalar values, you can use output parameters

create proc myproc
  @a int output,
  @b varchar(50) output
as
begin
  select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output

If you want to return a dataset, you can use insert exec

create proc myproc
as 
begin
     select name from sysobjects
end
go

declare @t table (name varchar(100))
insert @t (name)
exec myproc

You can even return a cursor but that's just horrid so I shan't give an example :)

Converting int64:

n := int64(32)
str := strconv.FormatInt(n, 10)

fmt.Println(str)
// Prints "32"

if any interested I've made a typescript version:

interface IResizeImageOptions {

  file: File;

const resizeImage = (settings: IResizeImageOptions) => {

  const maxSize = settings.maxSize;
  const reader = new FileReader();
  const image = new Image();
  const canvas = document.createElement('canvas');
  const dataURItoBlob = (dataURI: string) => {
    const bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
        atob(dataURI.split(',')[1]) :
        unescape(dataURI.split(',')[1]);
    const mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
    const max = bytes.length;
    const ia = new Uint8Array(max);
    for (var i = 0; i < max; i++) ia[i] = bytes.charCodeAt(i);
    return new Blob([ia], {type:mime});
  };
  const resize = () => {
    let width = image.width;
    let height = image.height;

    if (width > height) {
        if (width > maxSize) {
            height *= maxSize / width;
            width = maxSize;
        }
    } else {
        if (height > maxSize) {
            width *= maxSize / height;
            height = maxSize;
        }
    }

    canvas.width = width;
    canvas.height = height;
    canvas.getContext('2d').drawImage(image, 0, 0, width, height);
    let dataUrl = canvas.toDataURL('image/jpeg');
    return dataURItoBlob(dataUrl);
  };

  return new Promise((ok, no) => {
      if (!file.type.match(/image.*/)) {
        no(new Error("Not an image"));
        return;
      }

      reader.onload = (readerEvent: any) => {
        image.onload = () => ok(resize());
        image.src = readerEvent.target.result;

            image.onload = function () { return ok(resize()); };
            image.src = readerEvent.target.result;
        };
        reader.readAsDataURL(file);
    });
};

usage is like:

resizeImage({
    file: $image.files[0],
    maxSize: 500
}).then(function (resizedImage) {
    console.log("upload resized image")
}).catch(function (err) {
    console.error(err);
});

or (async/await):

const config = {
    file: $image.files[0],
    maxSize: 500
};
const resizedImage = await resizeImage(config)
console.log("upload resized image")

Answer corresponding to this by @Brad Parks Not sure about the MySQL version, but mine was 5.6, hence a little bit tweaking works:

I created a function debug_msg which is function (not procedure) and returns text(no character limit) and then call the function as SELECT debug_msg(params) AS my_res_set, code as below:

CREATE DEFINER=`root`@`localhost` FUNCTION `debug_msg`(`enabled` INT(11), `msg` TEXT) RETURNS text CHARSET latin1
    READS SQL DATA
BEGIN
    IF enabled=1 THEN
    return concat('** DEBUG:', "** ", msg);
    END IF;
END

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_func_call`(
 IN RegionID VARCHAR(20),
 IN RepCurrency INT(11),
 IN MGID INT(11),
 IN VNC VARCHAR(255)
)
BEGIN
    SET @enabled = TRUE;
    SET @mainQuery = "SELECT * FROM Users u";
    SELECT `debug_msg`(@enabled, @mainQuery) AS `debug_msg1`;
    SET @lastQuery = CONCAT(@mainQuery, " WHERE u.age>30);
    SELECT `debug_msg`(@enabled, @lastQuery) AS `debug_msg2`;
END $$

You may like to try something like this which covers all the bases, including not relying on whitespace after the number:

>>> import re
>>> numeric_const_pattern = r"""
...     [-+]? # optional sign
...     (?:
...         (?: \d* \. \d+ ) # .1 .12 .123 etc 9.1 etc 98.1 etc
...         |
...         (?: \d+ \.? ) # 1. 12. 123. etc 1 12 123 etc
...     )
...     # followed by optional exponent part if desired
...     (?: [Ee] [+-]? \d+ ) ?
...     """
>>> rx = re.compile(numeric_const_pattern, re.VERBOSE)
>>> rx.findall(".1 .12 9.1 98.1 1. 12. 1 12")
['.1', '.12', '9.1', '98.1', '1.', '12.', '1', '12']
>>> rx.findall("-1 +1 2e9 +2E+09 -2e-9")
['-1', '+1', '2e9', '+2E+09', '-2e-9']
>>> rx.findall("current level: -2.03e+99db")
['-2.03e+99']
>>>

For easy copy-pasting:

numeric_const_pattern = '[-+]? (?: (?: \d* \. \d+ ) | (?: \d+ \.? ) )(?: [Ee] [+-]? \d+ ) ?'
rx = re.compile(numeric_const_pattern, re.VERBOSE)
rx.findall("Some example: Jr. it. was .23 between 2.3 and 42.31 seconds")

Why wouldn't the user just hit the home button? Then they can exit your app from any of your activities, not just a specific one.

If you are worried about your application continuing to do something in the background. Make sure to stop it in the relevant onPause and onStop commands (which will get triggered when the user presses Home).

If your issue is that you want the next time the user clicks on your app for it to start back at the beginning, I recommend putting some kind of menu item or UI button on the screen that takes the user back to the starting activity of your app. Like the twitter bird in the official twitter app, etc.

Try this

$('#testID').addClass('nameOfClass');

or

$('#testID').removeClass('nameOfClass');

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

My problem was a misspelled component name inside the component.ts.

The import statement didn't show an error but the declaration did, which misled me.

if somebody constructs a ship, then engine, hull, electric-circuits etc. will be his "architectural elements". For him, engine-construction will be "design work".

If he then delegates the construction of the engine to another team, they will create an "engine architecture"...

So - it depends on the level of abstraction or detail. One persons' architecture might be anothers' design!

I faced a similar problem. I tried everything with ports, hosts and config files.But nothing helped.

I checked apache error logs. They showed the following error

(OS 10038)An operation was attempted on something that is not a socket.  : AH00332: winnt_accept: getsockname error on listening socket, is IPv6 available?

Finally this is what solved my problem.

1) Goto command prompt and run it in administrative mode. In windows 7 you can do it by typing cmd in run and then pressing ctrl+shift+enter

2) run the following command: netsh winsock reset

3) Restart the system

map function in python can be used. It takes two arguments. First argument is the function which has to be used for each element of the list. Second argument is the iterable.

a = [1, 2, 3]   
map(str, a)  
['1', '2', '3']

After converting the list into string you can use simple join function to combine list into a single string

a = map(str, a)    
''.join(a)      
'123'

in ActivitySaludo, this line,

    setContentView(txtCambiado);

you must set the content view for the activity only once.

Renders a view and sends the rendered HTML string to the client.

res.render('index');

Or

res.render('index', function(err, html) {
  if(err) {...}
  res.send(html);
});

This can also happen if you don't declare a route component in your feature module. So for example:

feature.routing.module.ts:

...
    {
        path: '',
        component: ViewComponent,
    }
...

feature.module.ts:

     imports: [ FeatureRoutingModule ],
     declarations: [],

Notice the ViewComponent is not in the declarations array, whereas it should be.

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }
});

Notice that now you access it through rootView view:

Button buttonClick = (Button)rootView.findViewById(R.id.button);

otherwise you would get again NullPointerException.

3 ways to do this:

In C Language (Command Line Tool) Works with Objective C, too:

printf("Hello World");

In Objective C:

NSLog(@"Hello, World!");

In Objective C with variables:

NSString * myString = @"Hello World";
NSLog(@"%@", myString);

In the code with variables, the variable created with class, NSString was outputted be NSLog. The %@ represents text as a variable.

I have some thoughts on how the best radio button implementation should look like. It can be based on UIButton class and use it's 'selected' state to indicate one from the group. The UIButton has native customisation options in IB, so it is convenient to design XIBs. Also there should be an easy way to group buttons using IB outlet connections:

I have implemented my ideas in this RadioButton class. Works like a charm:

Download the sample project.

DELETE     TABLE1 LIN
FROM TABLE1 LIN
INNER JOIN TABLE2 LCS ON  CONDITION
WHERE CONDITION

I didn't love the syntax of any of those. I really wanted to just specify what the items were and what the weighting of each was. I realize I could have used random.choices but instead I quickly wrote the class below.

import random, string
from numpy import cumsum

class randomChoiceWithProportions:
    '''
    Accepts a dictionary of choices as keys and weights as values. Example if you want a unfair dice:


    choiceWeightDic = {"1":0.16666666666666666, "2": 0.16666666666666666, "3": 0.16666666666666666
    , "4": 0.16666666666666666, "5": .06666666666666666, "6": 0.26666666666666666}
    dice = randomChoiceWithProportions(choiceWeightDic)

    samples = []
    for i in range(100000):
        samples.append(dice.sample())

    # Should be close to .26666
    samples.count("6")/len(samples)

    # Should be close to .16666
    samples.count("1")/len(samples)
    '''
    def __init__(self, choiceWeightDic):
        self.choiceWeightDic = choiceWeightDic
        weightSum = sum(self.choiceWeightDic.values())
        assert weightSum == 1, 'Weights sum to ' + str(weightSum) + ', not 1.'
        self.valWeightDict = self._compute_valWeights()

    def _compute_valWeights(self):
        valWeights = list(cumsum(list(self.choiceWeightDic.values())))
        valWeightDict = dict(zip(list(self.choiceWeightDic.keys()), valWeights))
        return valWeightDict

    def sample(self):
        num = random.uniform(0,1)
        for key, val in self.valWeightDict.items():
            if val >= num:
                return key

Please correct me if I'm wrong, but when Angular 2.0 is released I do not believe$rootScope will be around. My conjecture is based on the fact that $scope is being removed as well. Obviously controllers, will still exist, just not in the ng-controller fashion.Think of injecting controllers into directives instead. As the release comes imminent, it will be best to use services as global variables if you want an easier time to switch from verison 1.X to 2.0.

All of the Func delegates take at least one parameter

That's not true. They all take at least one type argument, but that argument determines the return type.

So Func<T> accepts no parameters and returns a value. Use Action or Action<T> when you don't want to return a value.

I have a similar situation, but I use the key and the certificate in different files.

in my case you can check the matching of the key and the lock by comparing the hashes (see https://michaelheap.com/curl-58-unable-to-set-private-key-file-server-key-type-pem/). This helped me to identify inconsistencies.

Try returning the dataset from your stored procedure to your datatable in C# or VB.Net. Then the large amount of data in your datatable can be copied to your destination table using a Bulk Copy. I have used BulkCopy for loading large datatables with thousands of rows, into Sql tables with great success in terms of performance.

You may want to experiment with BulkCopy in your C# or VB.Net code.

# here database details      
mysql_connect('hostname', 'username', 'password');
mysql_select_db('database-name');

$sql = "SELECT username FROM userregistraton";
$result = mysql_query($sql);

echo "<select name='username'>";
while ($row = mysql_fetch_array($result)) {
    echo "<option value='" . $row['username'] ."'>" . $row['username'] ."</option>";
}
echo "</select>";

# here username is the column of my table(userregistration)
# it works perfectly

There is a built-in middleware that makes it easier than writing a custom one.

Asp.Net Core 5 version:

app.UseExceptionHandler(a => a.Run(async context =>
{
    var exceptionHandlerPathFeature = context.Features.Get<IExceptionHandlerPathFeature>();
    var exception = exceptionHandlerPathFeature.Error;
    
    await context.Response.WriteAsJsonAsync(new { error = exception.Message });
}));

Older versions (they did not have WriteAsJsonAsync extension):

app.UseExceptionHandler(a => a.Run(async context =>
{
    var exceptionHandlerPathFeature = context.Features.Get<IExceptionHandlerPathFeature>();
    var exception = exceptionHandlerPathFeature.Error;
    
    var result = JsonConvert.SerializeObject(new { error = exception.Message });
    context.Response.ContentType = "application/json";
    await context.Response.WriteAsync(result);
}));

It should do pretty much the same, just a bit less code to write.

Important: Remember to add it before UseMvc (or UseRouting in .Net Core 3) as order is important.

dplyr >= 1.0.0 using across

sum up each row using rowSums (rowwise works for any aggreation, but is slower)

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(across(where(is.numeric))))

sum down each column

df %>%
   summarise(across(everything(), ~ sum(., is.na(.), 0)))

dplyr < 1.0.0

sum up each row

df %>%
   replace(is.na(.), 0) %>%
   mutate(sum = rowSums(.[1:5]))

sum down each column using superseeded summarise_all:

df %>%
   replace(is.na(.), 0) %>%
   summarise_all(funs(sum))

According to your package.json, you're using Angular 8.3, but you've imported angular/cdk v9. You can downgrade your angular/cdk version or you can upgrade your Angular version to v9 by running:

ng update @angular/core @angular/cli

That will update your local angular version to 9. Then, just to sync material, run: ng update @angular/material

Google has created a library for easy Permissions management. Its called EasyPermissions

Here is a simple example on requesting Location permission using this library.

public class MainActivity extends AppCompatActivity {

    private final int REQUEST_LOCATION_PERMISSION = 1;

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

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
}

@AfterPermissionsGranted(REQUEST_CODE) is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE has been granted.

This above case, the method requestLocationPermission() method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.

You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.

Essentially, yes!

• When a pattern circumvents the missing features (high order functions, stream handling...) that ultimalty facilitate composition.
• The need to re-write patterns' implementation again and again can itself be seen as a language smell.

Besides, this page (AreDesignPatternsMissingLanguageFeatures) provides a "pattern/feature" translation table and some nice discussions, if you are willing to dig.

There are many appropiate solution to this problem as mentioned above in this post, but i have found a small hack that can be inserrted in the script or pasted in the Chromes console (debugger) to achieve it:

jQuery(window).keydown(function(e) { if (e.keyCode == 123) debugger; });

This will cause execution to be paused when you hit F12.

I wanted to search for the term "Stripe" in all files except those within a plugin ("plugin" folder) or within the files ending in ".bak", ".bak2" or ".log" (this is within the wp-contents folder structure of a wordpress install).

I just wanted to do this search one time and very quickly, so I didn't want to alter the search settings of my environment. Here's how I did it (note the double asteriks for the folder):

• Search Term: Stripe
• Include Files: {blank}
• Exclude Files: *.bak*, *.log, **/plugins/**

Here's what it looked like

Some coding snobs look down on them as just a glorified global. In the same way that many people hate the goto statement there are others that hate the idea of ever using a global. I have seen several developers go to extraordinary lengths to avoid a global because they considered using one as an admission of failure. Strange but true.

In practice the Singleton pattern is just a programming technique that is a useful part of your toolkit of concepts. From time to time you might find it is the ideal solution and so use it. But using it just so you can boast about using a design pattern is just as stupid as refusing to ever use it because it is just a global.

You need to use DateTime.ParseExact with format "dd/MM/yyyy"

DateTime dt=DateTime.ParseExact("24/01/2013", "dd/MM/yyyy", CultureInfo.InvariantCulture);

Its safer if you use d/M/yyyy for the format, since that will handle both single digit and double digits day/month. But that really depends if you are expecting single/double digit values.

Your date format day/Month/Year might be an acceptable date format for some cultures. For example for Canadian Culture en-CA DateTime.Parse would work like:

DateTime dt = DateTime.Parse("24/01/2013", new CultureInfo("en-CA"));

Or

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en-CA");
DateTime dt = DateTime.Parse("24/01/2013"); //uses the current Thread's culture

Both the above lines would work because the the string's format is acceptable for en-CA culture. Since you are not supplying any culture to your DateTime.Parse call, your current culture is used for parsing which doesn't support the date format. Read more about it at DateTime.Parse.

Another method for parsing is using DateTime.TryParseExact

DateTime dt;
if (DateTime.TryParseExact("24/01/2013", 
                            "d/M/yyyy", 
                            CultureInfo.InvariantCulture, 
                            DateTimeStyles.None,
    out dt))
{
    //valid date
}
else
{
    //invalid date
}

The TryParse group of methods in .Net framework doesn't throw exception on invalid values, instead they return a bool value indicating success or failure in parsing.

Notice that I have used single d and M for day and month respectively. Single d and M works for both single/double digits day and month. So for the format d/M/yyyy valid values could be:

• "24/01/2013"
• "24/1/2013"
• "4/12/2013" //4 December 2013
• "04/12/2013"

To update entries other than appsettings, simply use XmlDocument.

public static void UpdateAppConfig(string tagName, string attributeName, string value)
{
    var doc = new XmlDocument();
    doc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
    var tags = doc.GetElementsByTagName(tagName);
    foreach (XmlNode item in tags)
    {
        var attribute = item.Attributes[attributeName];
        if (!ReferenceEquals(null, attribute))
            attribute.Value = value;
    }
    doc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
}

This is how you call it:

Utility.UpdateAppConfig("endpoint", "address", "http://localhost:19092/NotificationSvc/Notification.svc");

Utility.UpdateAppConfig("network", "host", "abc.com.au");

This method can be improved to cater for appSettings values as well.

To log MySQL in WAMP, you will need to edit the my.ini (e.g. under wamp\bin\mysql\mysql5.6.17\my.ini)

and add to [mysqld]:

general_log = 1
general_log_file="c:\\tmp\\mysql.log"

First you have to deactivate your environment before removing it. You can remove conda environment by using the following command

Suppose your environment name is "sample_env" , you can remove this environment by using

source deactivate    
conda remove -n sample_env --all

'--all' will be used to remove all the dependencies

At least as far back as Material Components 1.3.0-alpha03, it doesn't matter if the RecyclerView is nested (in something other than a ScrollView or NestedScrollView). Just put app:layout_behavior="@string/appbar_scrolling_view_behavior" on its top level parent that's a sibling of the AppBarLayout in the CoordinatorLayout.

This has been working for me when using a single Activity architecture with Jetpack Naviagation, where all Fragments are sharing the same AppBar from the Activity's layout. I make the FragmentContainer the direct child of the CoordinatorLayout that also contains the AppBarLayout, like below. The RecyclerViews in the various fragments are scrolling normally and the AppBar folds away and reappears as expected.

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:id="@+id/coordinatorLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <androidx.fragment.app.FragmentContainerView
            android:id="@+id/nav_host_fragment"
            android:name="androidx.navigation.fragment.NavHostFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            app:defaultNavHost="true"
            app:navGraph="@navigation/mobile_navigation"/>

        <com.google.android.material.appbar.AppBarLayout
            android:id="@+id/appbar_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:liftOnScroll="true">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:minHeight="?attr/actionBarSize"
                android:theme="?attr/actionBarTheme"
                app:layout_scrollFlags="scroll|enterAlways|snap" />

        </com.google.android.material.appbar.AppBarLayout>

    </androidx.coordinatorlayout.widget.CoordinatorLayout>

liftOnScroll (used to for app bars to look like they have zero elevation when at the top of the page) works if each fragment passes the ID of its RecyclerView to AppBarLayout.liftOnScrollTargetViewId in Fragment.onResume. Or pass 0 if the Fragment doesn't scroll.

When you reference Range like that it's called an unqualified reference because you don't specifically say which sheet the range is on. Unqualified references are handled by the "_Global" object that determines which object you're referring to and that depends on where your code is.

If you're in a standard module, unqualified Range will refer to Activesheet. If you're in a sheet's class module, unqualified Range will refer to that sheet.

inputTemplateContent is a variable that contains a reference to a range, probably a named range. If you look at the RefersTo property of that named range, it likely points to a sheet other than the Activesheet at the time the code executes.

The best way to fix this is to avoid unqualified Range references by specifying the sheet. Like

With ThisWorkbook.Worksheets("Template")
    .Range(inputTemplateHeader).Value = NO_ENTRY
    .Range(inputTemplateContent).Value = NO_ENTRY
End With

Adjust the workbook and worksheet references to fit your particular situation.

Add/Remove Programs also has to look into this registry key to find installations for the current user:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall

Applications like Google Chrome, Dropbox, or shortcuts installed through JavaWS (web start) JNLPs can be found only here.

I've seen all voted answers show how to set the summary with the exact current value, but the OP wanted also something like:

"Clean up messages after x days"* <- summary where x is the current Preference value

Here is my answer for achieving that

As per the documentation on ListPreference.getSummary():

Returns the summary of this ListPreference. If the summary has a String formatting marker in it (i.e. "%s" or "%1$s"), then the current entry value will be substituted in its place.

However, I tried this on several devices and it doesn't seem to work. With some research, I found a good solution in this answer. It simply consists of extending every Preference you use and override getSummary() to work as specified by Android documentation.

I've already had the proxies set as described above and it was working until today. Then it turned out that now I need "http://" in front of my proxy address: "http://{proxyURL}:{proxyPort}". Then it finally worked.

Try it -

        TypedArray a = null;
        if (defStyle != -1)
            a = getContext().obtainStyledAttributes(attributeSet, R.styleable.CheckBoxImageView, defStyle, 0);
        else
            a = getContext().obtainStyledAttributes(attributeSet, R.styleable.CheckBoxImageView);
        defImageRes = a.getResourceId(0, 0);
        checkedImageRes = a.getResourceId(1, 0);
        checked = a.getBoolean(2, false);
        a.recycle();
        setImageResource(checked ? checkedImageRes : defImageRes);
        setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        checked = !checked;
        setImageResource(checked ? checkedImageRes : defImageRes);
        onCheckedChangeListener.onCheckedChanged(this, checked);
    }

    public void setOnCheckedChangeListener(OnCheckedChangeListener onCheckedChangeListener) {
        this.onCheckedChangeListener = onCheckedChangeListener;
    }

    public static interface OnCheckedChangeListener {
        void onCheckedChanged(View buttonView, boolean isChecked);
    }
}

Add this attrib -

<declare-styleable name="CheckBoxImageView">
        <attr name="default_img" format="integer"/>
        <attr name="checked_img" format="integer"/>
        <attr name="checked" format="boolean"/>
</declare-styleable>

Use like -

 <com.adonta.ziva.consumer.wrapper.CheckBoxImageView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/checkBox"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:clickable="true"
        android:padding="5dp"
        app:checked_img="@drawable/check_box_checked"
        app:default_img="@drawable/check_box" />

It will fix all your porblems.

Try to use text-align in style attribute to align center.

<th class="not_mapped_style" style="text-align:center">DisplayName</th>

If you don't care what's in the cookie and you just want to use it, try this clean approach using request (a popular node module):

var request = require('request');
var j = request.jar();
var request = request.defaults({jar:j});
request('http://www.google.com', function () {
  request('http://images.google.com', function (error, response, body){
     // this request will will have the cookie which first request received
     // do stuff
  });
});

             if (reader.HasRows)
            {
                while (reader.Read())
                {
                    comboBox1.Items.Add(reader.GetString(0));
                }
            }
            reader.Close();

            MySqlDataReader reader1 = cmd1.ExecuteReader();
            if (reader1.HasRows)
            {
                while (reader1.Read())
                {
                    listBox1.Items.Add(reader1.GetString(0));
                }
            }
            reader1.Close();

There is no efficient way in the sense of algorithmic complexity (an algorithm with polynomial complexity) known in science by now. So iterating until the square root as already suggested is mostly as good as you can be.

Mainly because of this, a large part of the currently used cryptography is based on the assumption that it is very time consuming to compute a prime factorization of any given integer.

git reset --hard 1258f0d0aae

But be careful, if the descendant commits between 1258f0d0aae and HEAD are not referenced in other branches it'll be tedious (but not impossible) to recover them, so you'd better to create a "backup" branch at current HEAD, checkout master, and reset to the commit you want.

Also, be sure that you don't have uncommitted changes before a reset --hard, they will be truly lost (no way to recover).

"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.

In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

I spend a lot time to discover why my code could not find my file running Python 3 on the Windows system. So I added . before / and everything worked fine:

import os

script_dir = os.path.dirname(__file__)
file_path = os.path.join(script_dir, './output03.txt')
print(file_path)
fptr = open(file_path, 'w')

The simple solution is to remove IndexError by incorporating the condition:

if(index<(len(li)-1))

The error 'index out of range' will not occur now as the last index will not be reached. The idea is to access the next element while iterating. On reaching the penultimate element, you can access the last element.

Use enumerate method to add index or counter to an iterable(list, tuple, etc.). Now using the index+1, we can access the next element while iterating through the list.

li = [0, 1, 2, 3]

running = True
while running:
    for index, elem in enumerate(li):
        if(index<(len(li)-1)):
            thiselem = elem
            nextelem = li[index+1]

try this one for centos 7 : service crond reload

You can do this,

User.query.filter_by(id=123).delete()

or

User.query.filter(User.id == 123).delete()

Make sure to commit for delete() to take effect.

echo "Subject: test" | /usr/sbin/sendmail [email protected]

This enables you to do it within one command line without having to echo a text file. This answer builds on top of @mti2935's answer. So credit goes there.

In my case it was a simple bug in the code, using a variable before it was created. Worth checking that out before trying the above solutions. Why I got this particular error message, Lord knows.

This is default by iOS7 design. try to do the below:

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];

You can set the 'Separator Inset' from the storyboard:

Simple OSM Slippy Map Demo/Example

Click on "Run code snippet" to see an embedded OpenStreetMap slippy map with a marker on it. This was created with Leaflet.

Code

// Where you want to render the map.
var element = document.getElementById('osm-map');

// Height has to be set. You can do this in CSS too.
element.style = 'height:300px;';

// Create Leaflet map on map element.
var map = L.map(element);

// Add OSM tile leayer to the Leaflet map.
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

// Target's GPS coordinates.
var target = L.latLng('47.50737', '19.04611');

// Set map's center to target with zoom 14.
map.setView(target, 14);

// Place a marker on the same location.
L.marker(target).addTo(map);

<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>
<link href="https://unpkg.com/[email protected]/dist/leaflet.css" rel="stylesheet"/>
<div id="osm-map"></div>

Specs

• Uses OpenStreetMaps.
• Centers the map to the target GPS.
• Places a marker on the target GPS.
• Only uses Leaflet as a dependency.

Note:

I used the CDN version of Leaflet here, but you can download the files so you can serve and include them from your own host.

By default, the classes in the csv module use Windows-style line terminators (\r\n) rather than Unix-style (\n). Could this be what’s causing the apparent double line breaks?

If so, you can override it in the DictWriter constructor:

output = csv.DictWriter(open('file3.csv','w'), delimiter=',', lineterminator='\n', fieldnames=headers)

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

As of today, the quick & easy way to do it is:

if (Float.compare(sectionID, currentSectionID) == 0) {...}

However, the docs do not clearly specify the value of the margin difference (an epsilon from @Victor 's answer) that is always present in calculations on floats, but it should be something reasonable as it is a part of the standard language library.

Yet if a higher or customized precision is needed, then

float epsilon = Float.MIN_NORMAL;  
if(Math.abs(sectionID - currentSectionID) < epsilon){...}

is another solution option.

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

import re

htmlString = '</dd><dt> Fine, thank you.&#160;</dt><dd> Molt bé, gràcies. (<i>mohl behh, GRAH-syuhs</i>)'

SearchStr = '(\<\/dd\>\<dt\>)+ ([\w+\,\.\s]+)([\&\#\d\;]+)(\<\/dt\>\<dd\>)+ ([\w\,\s\w\s\w\?\!\.]+) (\(\<i\>)([\w\s\,\-]+)(\<\/i\>\))'

Result = re.search(SearchStr.decode('utf-8'), htmlString.decode('utf-8'), re.I | re.U)

print Result.groups()

Works that way. The expression contains non-latin characters, so it usually fails. You've got to decode into Unicode and use re.U (Unicode) flag.

I'm a beginner too and I faced that issue a couple of times myself.

I was having the exact same error in my development environment. In the end all I needed to do in order to fix it was to add:

config.assets.manifest = Rails.root.join("public/assets")

to my config/environments/development.rb file and it fixed it. My final config in development related to assets looks like:

config.assets.compress = false  
config.assets.precompile += %w[bootstrap-alerts.js] #Lots of other space separated files
config.assets.compile = false
config.assets.digest = true
config.assets.manifest = Rails.root.join("public/assets")
config.assets.debug = true

None of the solutions helped me here and I did this to solve my situation.

<a onclick="return clickEvent(event);" href="/contact-us">

And the function clickEvent(),

function clickEvent(event) {
    event.preventDefault();
    // do your thing here

    // remove the onclick event trigger and continue with the event
    event.target.parentElement.onclick = null;
    event.target.parentElement.click();
}

Like other answers I set org.gradle.java.home property in gradle.properties file. But path with \ separators did not work (building on windows 10):

Java home supplied via 'org.gradle.java.home' is invalid. Invalid directory: C:Program FilesJavajdk1.8.0_65

So instead of

org.gradle.java.home=C:\Program Files\Java\jdk1.8.0_65

i had to use

org.gradle.java.home=C:/Program Files/Java/jdk1.8.0_65

then the build was successful

Problem is that project is build with JRE instead of JDK and since I was building it from eclipse this also worked:

• In Window>Preferences>Gradle>Arguments specify Workspace JRE and specify your JDK.
• In Window>Preferences>Java>InstalledJREs specify your JDK as default

If one wants to support Generics (in an extension method) this is the pattern...

public  static List<T> Deserialize<T>(this string SerializedJSONString)
{
    var stuff = JsonConvert.DeserializeObject<List<T>>(SerializedJSONString);
    return stuff;
}

It is used like this:

var rc = new MyHttpClient(URL);
//This response is the JSON Array (see posts above)
var response = rc.SendRequest();
var data = response.Deserialize<MyClassType>();

MyClassType looks like this (must match name value pairs of JSON array)

[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
 public class MyClassType
 {
    [JsonProperty(PropertyName = "Id")]
    public string Id { get; set; }

    [JsonProperty(PropertyName = "Name")]
    public string Name { get; set; }

    [JsonProperty(PropertyName = "Description")]
    public string Description { get; set; }

    [JsonProperty(PropertyName = "Manager")]
    public string Manager { get; set; }

    [JsonProperty(PropertyName = "LastUpdate")]
    public DateTime LastUpdate { get; set; }
 }

Use NUGET to download Newtonsoft.Json add a reference where needed...

using Newtonsoft.Json;

$_SERVER["PHP_SELF"]; will give you the current filename and its path, but basename(__FILE__) should give you the filename that it is called from.

So

if(basename(__FILE__) == 'file_name.php') {
  //Hide
} else {
  //show
}

should do it.

Nothing helps me but this:

transparent_drawable.xml:

<?xml version="1.0" encoding="utf-8"?>    
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#00000000"/>
</shape>

layout.xml:

android:listSelector="@drawable/transparent_drawable"

Here is a code sample I've used (with a .NET Core view):

@{
    Microsoft.Extensions.Primitives.StringValues queryVal;

    if (Context.Request.Query.TryGetValue("yourKey", out queryVal) &&
        queryVal.FirstOrDefault() == "yourValue")
    {
    }
}

Right answer can be found in this (duplicate) question.

I reproduced the answer here (and it works!):

Just delete the .lock file in the .metadata directory in your eclipse workspace directory

Using "focus" will give keyboard users the same effect that mouse users get when they hover with a mouse. "Active" is needed to get the same effect in Internet Explorer.

The reality is, these states do not work as they should for all users. Not using all three selectors creates accessibility issues for many keyboard-only users who are physically unable to use a mouse. I invite you to take the #nomouse challenge (nomouse dot org).

I quickly wrote this C# console app to do this:

https://github.com/stuartjsmith/binarydetailer

Simply pass a directory as a parameter and it will do its best to tell you the net framework for each dll and exe in there

<span> elements are inline elements, as such layout properties such as width or margin don't work. You can fix that by either changing the <span> to a block element (such as <div>), or by using padding instead.

Note that making a span element a block element by adding display: block; is redundant, as a span is by definition a otherwise style-less inline element whereas div is an otherwise style-less block element. So the correct solution is to use a div instead of a block-span.

You are not allowed to have a CNAME record for the domain, as the CNAME is an aliasing feature that covers all data types (regardless of whether the client looks for MX, NS or SOA records). CNAMEs also always refer to a new name, not an ip-address, so there are actually two errors in the single line

@                        IN CNAME   88.198.38.XXX

Changing that CNAME to an A record should make it work, provided the ip-address you use is the correct one for your Heroku app.

The only correct way in DNS to make a simple domain.com name work in the browser, is to point the domain to an IP-adress with an A record.

Using stringstream for number conversion is dangerous!

See http://www.cplusplus.com/reference/ostream/ostream/operator%3C%3C/ where it tells that operator<< inserts formatted output.

Depending on your current locale an integer greater than 3 digits, could convert to a string of 4 digits, adding an extra thousands separator.

E.g., int = 1000 could be convertet to a string 1.001. This could make comparison operations not work at all.

So I would strongly recommend using the std::to_string way. It is easier and does what you expect.

Updated (see comments below):

C++17 provides std::to_chars as a higher-performance locale-independent alternative

The following is an instantiation of the various "just print it" suggestions. I found it instructive.

#include "stdio.h"

int main() {
    static int x = 5;
    static int *p = &x;
    printf("(int) p   => %d\n",(int) p);
    printf("(int) p++ => %d\n",(int) p++);
    x = 5; p = &x;
    printf("(int) ++p => %d\n",(int) ++p);
    x = 5; p = &x;
    printf("++*p      => %d\n",++*p);
    x = 5; p = &x;
    printf("++(*p)    => %d\n",++(*p));
    x = 5; p = &x;
    printf("++*(p)    => %d\n",++*(p));
    x = 5; p = &x;
    printf("*p++      => %d\n",*p++);
    x = 5; p = &x;
    printf("(*p)++    => %d\n",(*p)++);
    x = 5; p = &x;
    printf("*(p)++    => %d\n",*(p)++);
    x = 5; p = &x;
    printf("*++p      => %d\n",*++p);
    x = 5; p = &x;
    printf("*(++p)    => %d\n",*(++p));
    return 0;
}

It returns

(int) p   => 256688152
(int) p++ => 256688152
(int) ++p => 256688156
++*p      => 6
++(*p)    => 6
++*(p)    => 6
*p++      => 5
(*p)++    => 5
*(p)++    => 5
*++p      => 0
*(++p)    => 0

I cast the pointer addresses to ints so they could be easily compared.

I compiled it with GCC.

Yet another possible cause:

In my case, I had a xib and was calling Bundle.main.loadNibNamed(... at which point it was crashing. All my IBOutlets and IBActions seemed fine. In the end I noticed that the nib was actually loading, but then when I tried to access the first (and only) view (nib.first), that was not working. In fact nib.count was returning a very large integer (max int?), instead of the expected 1. I tried re-adding the view, but still no luck.

In the end, I deleted the whole xib file and started again (but I kept some of the views in my clipboard so I can paste them instead of recreating them again).

This worked!

I agree with Duncan ...I have tried it with mutable object but still get the same problem... I got a simple solution to this... use ListIterator instead Iterator and use set method of ListIterator

ListIterator<Integer> i = a.listIterator();
//changed the value of first element in List
Integer x =null;
        if(i.hasNext()) {
            x = i.next();
            x = Integer.valueOf(9);
        }
    //set method sets the recent iterated element in ArrayList
    i.set(x);
        //initialized the iterator again and print all the elements
        i = a.listIterator();
        while(i.hasNext())
        System.out.print(i.next());

But this constraints me to use this only for ArrayList only which can use ListIterator...i will have same problem with any other Collection

Since I had a similar situation, I thought I'd share my situation and how these answers helped me (thanks everyone).

So I decided to work locally by amending my last commit every time I wanted to save my progress on the main branch (I know, I should've branched out, committed on that, kept pushing and later merge back to master).

One late night, in paranoid fear of loosing my progress to hardware failure or something out of the ether, I decided to push master to origin. Later I kept amending my local master branch and when I decided it's time to push again, I was faced with different master branches and found out I can't amend origin/upstream (duh!) like I can local development branches.

So I didn't checkout master locally because I already was after a commit. Master was unchanged. I didn't even need to reset --hard, my current commit was OK.

I just forced push to origin, without even specifying what commit I wanted to force on master since in this case it's whatever HEAD is at. Checked git diff master..origin/master so there weren't any differences and that's it. All fixed. Thanks! (I know, I'm a git newbie, please forgive!).

So if you're already OK with your master branch locally, just:

git push --force origin master
git diff master..origin/master

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

Problem with DIR is that it will return wrong answers. If you are looking for DOC in a folder by using DIR *.DOC it will also give you the DOCX. Searching for *.HTM will also give the HTML and so on...

For anyone else finding this - its worth noting that you can set the key value in the input name. Thanks to the answer in POSTing Form Fields with same Name Attribute you also can interplay strings or integers without quoting.

The answers assume that you don't mind the key value coming back for PHP however you can set name=[yourval] (string or int) which then allows you to refer to an existing record.

Yep, you can use border: 1px solid transparent

Another solution is to use outline on hover (and set the border to 0) which doesn't affect the document flow:

li{
    display:inline-block;
    padding:5px;
    border:0;
}
li:hover{
    outline:1px solid #FC0;
}

NB. You can only set the outline as a sharthand property, not for individual sides. It's only meant to be used for debugging but it works nicely.

A Stack is a LIFO (Last In First Out) data structure. The push and pop operations are simple. Push puts something on the stack, pop takes something off. You put onto the top, and take off the top, to preserve the LIFO order.

edit -- corrected from FIFO, to LIFO. Facepalm!

to illustrate, you start with a blank stack

|

then you push 'x'

| 'x'

then you push 'y'

| 'x' 'y'

then you pop

| 'x'

The Answer by OscarRyz is correct, and should have been the accepted Answer. But now that Answer is out-dated.

java.time

In Java 8 and later, we have the new java.time package (inspired by Joda-Time, defined by JSR 310, with tutorial, extended by ThreeTen-Extra project).

Avoid Old Date-Time Classes

The old java.util.Date/.Calendar, SimpleDateFormat, and java.sql.Date classes are a confusing mess. For one thing, j.u.Date has date and time-of-day while j.s.Date is date-only without time-of-day. Oh, except that j.s.Date only pretends to not have a time-of-day. As a subclass of j.u.Date, j.s.Date inherits the time-of-day but automatically adjusts that time-of-day to midnight (00:00:00.000). Confusing? Yes. A bad hack, frankly.

For this and many more reasons, those old classes should be avoided, used only a last resort. Use java.time where possible, with Joda-Time as a fallback.

LocalDate

In java.time, the LocalDate class cleanly represents a date-only value without any time-of-day or time zone. That is what we need for this Question’s solution.

To get that LocalDate object, we parse the input string. But rather than use the old SimpleDateFormat class, java.time provides a new DateTimeFormatter class in the java.time.format package.

String input = "01/01/2009" ;
DateTimeFormatter formatter = DateTimeFormatter.ofPattern( "MM/dd/yyyy" ) ;
LocalDate localDate = LocalDate.parse( input, formatter ) ;

JDBC drivers compliant with JDBC 4.2 or later can use java.time types directly via the PreparedStatement::setObject and ResultSet::getObject methods.

PreparedStatement pstmt = connection.prepareStatement(
    "INSERT INTO USERS ( USER_ID, FIRST_NAME, LAST_NAME, SEX, DATE ) " +
    " VALUES (?, ?, ?, ?, ? )");

pstmt.setString( 1, userId );
pstmt.setString( 3, myUser.getLastName() ); 
pstmt.setString( 2, myUser.getFirstName() ); // please use "getFir…" instead of "GetFir…", per Java conventions.
pstmt.setString( 4, myUser.getSex() );
pstmt.setObject( 5, localDate ) ;  // Pass java.time object directly, without any need for java.sql.*. 

But until you have such an updated JDBC driver, fallback on using the java.sql.Date class. Fortunately, that old java.sql.Date class has been gifted by Java 8 with a new convenient conversion static method, valueOf( LocalDate ).

In the sample code of the sibling Answer by OscarRyz, replace its "sqlDate =" line with this one:

java.sql.Date sqlDate = java.sql.Date.valueOf( localDate ) ;

For python3 on Ubuntu

 sudo apt-get install python3-setuptools

Your return data approach is correct, that's an example of promise chaining. If you return a promise from your .then() callback, JavaScript will resolve that promise and pass the data to the next then() callback.

Just be careful and make sure you handle errors with .catch(). Promise.all() rejects as soon as one of the promises in the array rejects.

If they really absolutely have to remain unsorted (which they really don't.. and if you're dealing with hundreds of thousands of elements then I have to ask why you would be comparing vectors like this), you can hack together a compare method which works with unsorted arrays.

The only way I though of to do that was to create a temporary vector3 and pretend to do a set_intersection by adding all elements of vector1 to it, then doing a search for each individual element of vector2 in vector3 and removing it if found. I know that sounds terrible, but that's why I'm not writing any C++ standard libraries anytime soon.

Really, though, just sort them first.

For MVC 5 just look inside the EnableTwoFactorAuthentication method of ManageController in WebApplication template scaffold, its being done there:

        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> EnableTwoFactorAuthentication()
        {
            await UserManager.SetTwoFactorEnabledAsync(User.Identity.GetUserId(), true);
            var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
            if (user != null)
            {
                await SignInManager.SignInAsync(user, isPersistent: false, rememberBrowser: false);
            }
            return RedirectToAction("Index", "Manage");
        }

The answer is right there as suggested by Microsoft itself:

var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());

It will have all the additional properties you defined in ApplicationUser class.

You can use TreeMap which internally implements the SortedMap below is the example

Sorting by ascending ordering :

  Map<Float, String> ascsortedMAP = new TreeMap<Float, String>();

  ascsortedMAP.put(8f, "name8");
  ascsortedMAP.put(5f, "name5");
  ascsortedMAP.put(15f, "name15");
  ascsortedMAP.put(35f, "name35");
  ascsortedMAP.put(44f, "name44");
  ascsortedMAP.put(7f, "name7");
  ascsortedMAP.put(6f, "name6");

  for (Entry<Float, String> mapData : ascsortedMAP.entrySet()) {
    System.out.println("Key : " + mapData.getKey() + "Value : " + mapData.getValue());
  }

Sorting by descending ordering :

If you always want this create the map to use descending order in general, if you only need it once create a TreeMap with descending order and put all the data from the original map in.

  // Create the map and provide the comparator as a argument
  Map<Float, String> dscsortedMAP = new TreeMap<Float, String>(new Comparator<Float>() {
    @Override
    public int compare(Float o1, Float o2) {
      return o2.compareTo(o1);
    }
  });
  dscsortedMAP.putAll(ascsortedMAP);

for further information about SortedMAP read http://examples.javacodegeeks.com/core-java/util/treemap/java-sorted-map-example/

You want a capture group.

p = re.compile("name (.*) is valid", re.flags) # parentheses for capture groups
print p.match(s).groups() # This gives you a tuple of your matches.

So I actually added a category to UINavigationController but used the methods:

-(UIViewController *)childViewControllerForStatusBarStyle;
-(UIViewController *)childViewControllerForStatusBarHidden;

and had those return the current visible UIViewController. That lets the current visible view controller set its own preferred style/visibility.

Here's a complete code snippet for it:

In Swift:

extension UINavigationController {

    public override func childViewControllerForStatusBarHidden() -> UIViewController? {
        return self.topViewController
    }

    public override func childViewControllerForStatusBarStyle() -> UIViewController? {
        return self.topViewController
    }
}

In Objective-C:

@interface UINavigationController (StatusBarStyle)

@end

@implementation UINavigationController (StatusBarStyle)

-(UIViewController *)childViewControllerForStatusBarStyle {
    return self.topViewController;
}

-(UIViewController *)childViewControllerForStatusBarHidden {
    return self.topViewController;
}

@end

And for good measure, here's how it's implemented then in a UIViewController:

In Swift

override public func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}

override func prefersStatusBarHidden() -> Bool {
    return false
}

In Objective-C

-(UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent; // your own style
}

- (BOOL)prefersStatusBarHidden {
    return NO; // your own visibility code
}

Finally, make sure your app plist does NOT have the "View controller-based status bar appearance" set to NO. Either delete that line or set it to YES (which I believe is the default now for iOS 7?)

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

You are going right way my friend.Now if you want retrive cookie anywhere in project just put this code $val = Cookie::get('COOKIE_NAME'); That's it! For more information how can this done click here

I have created the following class and used across the application wherever required in place of GridView:

/// <summary>
/// Represents a view mode that displays data items in columns for a System.Windows.Controls.ListView control with auto sized columns based on the column content     
/// </summary>
public class AutoSizedGridView : GridView
{        
    protected override void PrepareItem(ListViewItem item)
    {
        foreach (GridViewColumn column in Columns)
        {
            // Setting NaN for the column width automatically determines the required
            // width enough to hold the content completely.

            // If the width is NaN, first set it to ActualWidth temporarily.
            if (double.IsNaN(column.Width))
              column.Width = column.ActualWidth;

            // Finally, set the column with to NaN. This raises the property change
            // event and re computes the width.
            column.Width = double.NaN;              
        }            
        base.PrepareItem(item);
    }
}

This is my solution. When Set-Location fails it throws a non-terminating error which is not seen by the catch block. Adding -ErrorAction Stop is the easiest way around this.

try {
    Set-Location "$YourPath" -ErrorAction Stop;
} catch {
    Write-Host "Exception has been caught";
}

This should have what you need, check out the jsfiddle at the bottom:

$(document).ready(function () {
$('#txt').val($("input[type=checkbox]:checked").length);
$('#txt2').val($("input[type=checkbox]").length);

$('input[type=checkbox]').change(function () {
checked = $("input[type=checkbox]:checked").length;
$('#block').show();
$('#block2').hide();
if (checked > 0) {
  $('#block').hide();
  $('#block2').show();
  $('#txt').val(checked);
 }
});
});

2 Here a short ES6 variadic version:

function objectsHaveSameKeys(...objects) {
   const allKeys = objects.reduce((keys, object) => keys.concat(Object.keys(object)), []);
   const union = new Set(allKeys);
   return objects.every(object => union.size === Object.keys(object).length);
}

A little performance test (MacBook Pro - 2,8 GHz Intel Core i7, Node 5.5.0):

var x = {};
var y = {};

for (var i = 0; i < 5000000; ++i) {
    x[i] = i;
    y[i] = i;
}

Results:

objectsHaveSameKeys(x, y) // took  4996 milliseconds
compareKeys(x, y)               // took 14880 milliseconds
hasSameProps(x,y)               // after 10 minutes I stopped execution

Your regex will match anything that contains a number, you want to use anchors to match the whole string and then match one or more numbers:

regex = new Regex("^[0-9]+$");

The ^ will anchor the beginning of the string, the $ will anchor the end of the string, and the + will match one or more of what precedes it (a number in this case).

No, that's pretty much it. In theory you could use visibility: collapse on some <col>?s to do it, but browser support isn't all there.

To improve what you've got slightly, you could use table-layout: fixed on the <table> to allow the browser to use the simpler, faster and more predictable fixed-table-layout algorithm. You could also drop the .show rules as when a cell isn't made display: none by a .hide rule it will automatically be display: table-cell. Allowing table display to revert to default rather than setting it explicitly avoids problems in IE<8, where the table display values are not supported.

You are returning char, and not char*, which is the pointer to the first character of an array.

If you want to return a new character array instead of doing in-place modification, you can ask for an already allocated pointer (char*) as parameter or an uninitialized pointer. In this last case you must allocate the proper number of characters for new string and remember that in C parameters as passed by value ALWAYS, so you must use char** as parameter in the case of array allocated internally by function. Of course, the caller must free that pointer later.

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

here's an idea... just pull down one full page of results from each of the three and then throw out the 20 least useful ones... this eliminates the large querysets and that way you only sacrifice a little performance instead of a lot

The following will print the line matching TERMINATE till the end of the file:

sed -n -e '/TERMINATE/,$p'

Explained: -n disables default behavior of sed of printing each line after executing its script on it, -e indicated a script to sed, /TERMINATE/,$ is an address (line) range selection meaning the first line matching the TERMINATE regular expression (like grep) to the end of the file ($), and p is the print command which prints the current line.

This will print from the line that follows the line matching TERMINATE till the end of the file:
(from AFTER the matching line to EOF, NOT including the matching line)

sed -e '1,/TERMINATE/d'

Explained: 1,/TERMINATE/ is an address (line) range selection meaning the first line for the input to the 1st line matching the TERMINATE regular expression, and d is the delete command which delete the current line and skip to the next line. As sed default behavior is to print the lines, it will print the lines after TERMINATE to the end of input.

Edit:

If you want the lines before TERMINATE:

sed -e '/TERMINATE/,$d'

And if you want both lines before and after TERMINATE in 2 different files in a single pass:

sed -e '1,/TERMINATE/w before
/TERMINATE/,$w after' file

The before and after files will contain the line with terminate, so to process each you need to use:

head -n -1 before
tail -n +2 after

Edit2:

IF you do not want to hard-code the filenames in the sed script, you can:

before=before.txt
after=after.txt
sed -e "1,/TERMINATE/w $before
/TERMINATE/,\$w $after" file

But then you have to escape the $ meaning the last line so the shell will not try to expand the $w variable (note that we now use double quotes around the script instead of single quotes).

I forgot to tell that the new line is important after the filenames in the script so that sed knows that the filenames end.

Edit: 2016-0530

Sébastien Clément asked: "How would you replace the hardcoded TERMINATE by a variable?"

You would make a variable for the matching text and then do it the same way as the previous example:

matchtext=TERMINATE
before=before.txt
after=after.txt
sed -e "1,/$matchtext/w $before
/$matchtext/,\$w $after" file

to use a variable for the matching text with the previous examples:

## Print the line containing the matching text, till the end of the file:
## (from the matching line to EOF, including the matching line)
matchtext=TERMINATE
sed -n -e "/$matchtext/,\$p"

## Print from the line that follows the line containing the 
## matching text, till the end of the file:
## (from AFTER the matching line to EOF, NOT including the matching line)
matchtext=TERMINATE
sed -e "1,/$matchtext/d"

## Print all the lines before the line containing the matching text:
## (from line-1 to BEFORE the matching line, NOT including the matching line)
matchtext=TERMINATE
sed -e "/$matchtext/,\$d"

The important points about replacing text with variables in these cases are:

1. Variables ($variablename) enclosed in single quotes ['] won't "expand" but variables inside double quotes ["] will. So, you have to change all the single quotes to double quotes if they contain text you want to replace with a variable.
2. The sed ranges also contain a $ and are immediately followed by a letter like: $p, $d, $w. They will also look like variables to be expanded, so you have to escape those $ characters with a backslash [\] like: \$p, \$d, \$w.

That part is written to stderr, use 2> to redirect it. For example:

foo > stdout.txt 2> stderr.txt

or if you want in same file:

foo > allout.txt 2>&1

Note: this works in (ba)sh, check your shell for proper syntax

In the Web Developer Toolbar, have you tried the Tools -> Validate HTML or Tools -> Validate Local HTML options?

The Validate HTML option sends the url to the validator, which works well with publicly facing sites. The Validate Local HTML option sends the current page's HTML to the validator, which works well with pages behind a login, or those that aren't publicly accessible.

You may also want to try View Source Chart (also as FireFox add-on). An interesting note there:

Q. Why does View Source Chart change my XHTML tags to HTML tags?

A. It doesn't. The browser is making these changes, VSC merely displays what the browser has done with your code. Most common: self closing tags lose their closing slash (/). See this article on Rendered Source for more information (archive.org).

Try this

    final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
    scrollview.post(new Runnable() {
       @Override
       public void run() {
         scrollview.fullScroll(ScrollView.FOCUS_DOWN);
       }
    });

C is meant to be a step above assembly language. The C if-statement is really just syntactical sugar for "branch-if-zero", so the idea of booleans as an independent datatype was a foreign concept at the time. (1)

Even now, C/C++ booleans are usually little more than an alias for a single byte data type. As such, it's really more of a purposing label than an independent datatype.

(1) Of course, modern compilers are a bit more advanced in their handling of if statements. This is from the standpoint of C as a new language.

This can also be used

$('#name2').change(function(){
    $('#name').val('');//You can set the first value of first one if that is not empty
});


$('#name').change(function(){
    $('#name2').val('');
});

This is what worked for me:

import json
import requests
url = 'http://xxx.com'
payload = {'param': '1', 'data': '2', 'field': '4'}
headers = {'content-type': 'application/json'}
r = requests.post(url, data = json.dumps(payload), headers = headers)

Here is using just one command without cURL. Super simple.

echo file_get_contents('https://www.server.com', false, stream_context_create([
    'http' => [
        'method' => 'POST',
        'header'  => "Content-type: application/x-www-form-urlencoded",
        'content' => http_build_query([
            'key1' => 'Hello world!', 'key2' => 'second value'
        ])
    ]
]));

Why don't you examine System.getProperty("os.arch") value in your code?

I was facing the same problem. For my solution, I added br enclosed between 2 brackets < > enclosed in double quotation marks, and preceded and followed by the + sign:

+"<br>"+

Try this in your browser and see, it certainly works in my Internet Explorer.

PHP 7.0 $_SERVER varibales have changed. var_dump it and see how it fits your reqs.

CMake 3.X

CMake 3.X offers a 'clean' target.

cmake --build C:/foo/build/ --target clean

From the CMake docs for 3.0.2:

--clean-first  = Build target 'clean' first, then build.
                 (To clean only, use --target 'clean'.)

CMake 2.X

There is no cmake clean in CMake version 2.X

I usually build the project in a single folder like "build". So if I want to make clean, I can just rm -rf build.

The "build" folder in the same directory as the root "CMakeLists.txt" is usually a good choice. To build your project, you simply give cmake the location of the CMakeLists.txt as an argument. For example: cd <location-of-cmakelists>/build && cmake ... (From @ComicSansMS)

You can use use findFragmentById in FragmentManager.

Since you are using the Support library (you are extending FragmentActivity) you can use:

getSupportFragmentManager().findFragmentById(R.id.pageview)

If you are not using the support library (so you are on Honeycomb+ and you don't want to use the support library):

getFragmentManager().findFragmentById(R.id.pageview)

Please consider that using the support library is recommended even on Honeycomb+.

In order to execute a spool file in plsql Go to File->New->command window -> paste your code-> execute. Got to the directory and u will find the file.

Select ColumnB and as two CF formula rules apply:

Green: =AND(B1048576="X",B1="Y")

Red: =AND(B1048576="X",B1="W")

This was probably a casting issue. Casting syntax happens when you try to combine two different types of variables. Since we cannot convert a string to an integer or float always, we have to convert our integers into a string. This is how you do it.: str(x). To convert to a integer, it's: int(x), and a float is float(x). Our code will be:

print('Total score for ' + str(name) + ' is ' + str(score))

Also! Run this snippet to see a table of how to convert different types of variables!

<table style="border-collapse: collapse; width: 100%;background-color:maroon; color: #00b2b2;">

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

I think this works:

int roundUp(int numToRound, int multiple) {
    return multiple? !(numToRound%multiple)? numToRound : ((numToRound/multiple)+1)*multiple: numToRound;
}

1. Verify current version of PHP Type in the following to see the current PHP version:

   php -v

   Should output something like:

   PHP 5.3.3 (cli) (built: Jul 9 2015 17:39:00) Copyright (c) 1997-2010 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

2. Install the Remi and EPEL RPM repositories

If you haven’t already done so, install the Remi and EPEL repositories

wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm && rpm -Uvh epel-release-latest-6.noarch.rpm



wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm && rpm -Uvh remi-release-6*.rpm

Enable the REMI repository globally:

nano /etc/yum.repos.d/remi.repo

Under the section that looks like [remi] make the following changes:

[remi]
name=Remi's RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/remi/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/remi/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Also, under the section that looks like [remi-php55] make the following changes:

[remi-php56]
name=Remi's PHP 5.6 RPM repository for Enterprise Linux 6 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/6/php56/$basearch/
mirrorlist=http://rpms.remirepo.net/enterprise/6/php56/mirror
# WARNING: If you enable this repository, you must also enable "remi"
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

Type CTRL-O to save and CTRL-X to close the editor

3. Upgrade PHP 5.3 to PHP 5.6 Now we can upgrade PHP. Simply type in the following command:

   yum -y upgrade php*

Once the update has completed, let’s verify that you have PHP 5.6 installed:

php -v

Should see output similar to the following:

PHP 5.6.14 (cli) (built: Sep 30 2015 14:07:43) 
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies

Arrays have numerical indexes. So,

a = new Array();
a['a1']='foo';
a['a2']='bar';

and

b = new Array(2);
b['b1']='foo';
b['b2']='bar';

are not adding elements to the array, but adding .a1 and .a2 properties to the a object (arrays are objects too). As further evidence, if you did this:

a = new Array();
a['a1']='foo';
a['a2']='bar';
console.log(a.length);   // outputs zero because there are no items in the array

Your third option:

c=['c1','c2','c3'];

is assigning the variable c an array with three elements. Those three elements can be accessed as: c[0], c[1] and c[2]. In other words, c[0] === 'c1' and c.length === 3.

Javascript does not use its array functionality for what other languages call associative arrays where you can use any type of key in the array. You can implement most of the functionality of an associative array by just using an object in javascript where each item is just a property like this.

a = {};
a['a1']='foo';
a['a2']='bar';

It is generally a mistake to use an array for this purpose as it just confuses people reading your code and leads to false assumptions about how the code works.

Try this, its work for me:

Date date = javax.xml.bind.DatatypeConverter.parseDateTime("2013-06-01T12:45:01+04:00").getTime();

In Java 8:

OffsetDateTime dt = OffsetDateTime.parse("2010-03-01T00:00:00-08:00");

If the issue is consistent and happened about 10-15 times in a row even after changing file permissions to 400 or 600, then it is most certainly something is wrong on the ec2 instance, so to make sure:

1. Check the logs when you try to ssh to the instance by adding -v at the end and see either it gives out anything specific.

2. Make sure you use the correct name for ssh, like Ubuntu. Perhaps that depends on Linux distribution and users you added and either you've given permission for "root user" ssh.

Then if nothing helps, follow the documentation here https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectingMindTerm to fix that. It helped in my case, and it happened because of messed up directories/files permissions.

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

How about this function:

public static String toString(final Collection<?> collection) {
    final StringBuilder sb = new StringBuilder("{");
    boolean isFirst = true;
    for (final Object object : collection) {
        if (!isFirst)
            sb.append(',');
        else
            isFirst = false;
        sb.append(object);
    }
    sb.append('}');
    return sb.toString();
}

it works for any type of collection...

I have something to add to Aladin's answer:

1. Your view controller should conform to UITextFieldDelegate

   class MyViewController: UIViewController, UITextViewDelegate {
   
   }
   

2. Set the delegate of your textfield: To set the delegate, you can control drag from the textfield to your view controller in the storyboard. I think this is preferable to setting it in code

3. Implement the method in your view controller : textField(_:shouldChangeCharactersInRange:replacementString:)

Try this

Console.WriteLine("\a")

Just delete the forked repo from your GitHub account.

https://help.github.com/articles/deleting-a-repository/

• If I go to admin panel on GitHub there's a delete option. If I delete it as the option above, will it make any effect in the original one or not?

It wont make any changes in the original one; cos, its your repo now.

As pointed out by others, this problem "is caused by an untrusted SSL certificate". My answer is based on the top-rated answer and this answer.

You can test the certificate using curl:

curl -vvI https://example.com

If an error returns, you have 3 options:

1. For a quick fix, you could just not verify the certificate:

requests.get('https://example.com', verify=False)

2. Pass the path to the CA_BUNDLE file or directory with certificates of trusted CAs:

requests.get('https://example.com', verify='/path/to/certfile')

3. If you have access to, fix the web server certificate.

My problem was because I was using only my site's certificate, not the intermediate (a.k.a. chain) certificate.

If you are using Let's Encrypt, you should use the fullchain.pem file, not cert.pem.

For those using Cobertura and only have the Coverage Session View like I do,just try closing Eclipse and starting it up again. This got rid of the highlighting for me.

You're correct in that, semantically, ref provides both "in" and "out" functionality, whereas out only provides "out" functionality. There are some things to consider:

1. out requires that the method accepting the parameter MUST, at some point before returning, assign a value to the variable. You find this pattern in some of the key/value data storage classes like Dictionary<K,V>, where you have functions like TryGetValue. This function takes an out parameter that holds what the value will be if retrieved. It wouldn't make sense for the caller to pass a value into this function, so out is used to guarantee that some value will be in the variable after the call, even if it isn't "real" data (in the case of TryGetValue where the key isn't present).
2. out and ref parameters are marshaled differently when dealing with interop code

Also, as an aside, it's important to note that while reference types and value types differ in the nature of their value, every variable in your application points to a location of memory that holds a value, even for reference types. It just happens that, with reference types, the value contained in that location of memory is another memory location. When you pass values to a function (or do any other variable assignment), the value of that variable is copied into the other variable. For value types, that means that the entire content of the type is copied. For reference types, that means that the memory location is copied. Either way, it does create a copy of the data contained in the variable. The only real relevance that this holds deals with assignment semantics; when assigning a variable or passing by value (the default), when a new assignment is made to the original (or new) variable, it does not affect the other variable. In the case of reference types, yes, changes made to the instance are available on both sides, but that's because the actual variable is just a pointer to another memory location; the content of the variable--the memory location--didn't actually change.

Passing with the ref keyword says that both the original variable and the function parameter will actually point to the same memory location. This, again, affects only assignment semantics. If a new value is assigned to one of the variables, then because the other points to the same memory location the new value will be reflected on the other side.

Another way to do it is using a limit method:

Listing::limit(10)->get();

This can be useful if you're not trying to implement pagination, but for example, return 10 random rows from a table:

Listing::inRandomOrder()->limit(10)->get();

Also, you are not allowed spaces between comma separated field names.

BAD: -f firstname, lastname

GOOD: -f firstname,lastname

Disable time zone. Use challenge.datetime_start.replace(tzinfo=None);

You can also use replace(tzinfo=None) for other datetime.

if challenge.datetime_start.replace(tzinfo=None) <= datetime.now().replace(tzinfo=None) <= challenge.datetime_end.replace(tzinfo=None):

You can pass the authorised keys in to your container using a shared folder and set permissions using a docker file like this:

FROM ubuntu:16.04
RUN apt-get install -y openssh-server
RUN mkdir /var/run/sshd
EXPOSE 22
RUN cp /root/auth/id_rsa.pub /root/.ssh/authorized_keys
RUN rm -f /root/auth
RUN chmod 700 /root/.ssh
RUN chmod 400 /root/.ssh/authorized_keys
RUN chown root. /root/.ssh/authorized_keys
CMD /usr/sbin/sshd -D

And your docker run contains something like the following to share an auth directory on the host (holding the authorised_keys) with the container then open up the ssh port which will be accessable through port 7001 on the host.

-d -v /home/thatsme/dockerfiles/auth:/root/auth -–publish=127.0.0.1:7001:22

You may want to look at https://github.com/jpetazzo/nsenter which appears to be another way to open a shell on a container and execute commands within a container.

After reviewing all the other answers, I ended up with this:

function oldSchoolMakeBuild(cb) {
    var makeProcess = exec('make -C ./oldSchoolMakeBuild',
         function (error, stdout, stderr) {
             stderr && console.error(stderr);
             cb(error);
        });
    makeProcess.stdout.on('data', function(data) {
        process.stdout.write('oldSchoolMakeBuild: '+ data);
    });
}

Sometimes data will be multiple lines, so the oldSchoolMakeBuild header will appear once for multiple lines. But this didn't bother me enough to change it.

I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany to look at each item in each group.

I think you just want:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new ResultLine
            {
                ProductName = cl.First().Name,
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

The use of First() here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.

I'd also suggest that you should change the Quantity and Price properties to be int and decimal types respectively - why use a string property for data which is clearly not textual?

use android:theme="@android:style/Theme.NoTitleBar in manifest file's application tag to remove the title bar for whole application or put it in activity tag to remove the title bar from a single activity screen.

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

Intellij User, make sure you have 3 things,

1. Lombok dependency

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.8</version>
            <scope>provided</scope>
        </dependency>

2. IntelliJ plugin for Lombok

3. Lombok annotation, like @Getter @Setter (make sure it is coming from lombok and not from somewhere else)

and it should work.

PDOStatement::fetch returns a row from the result set. The parameter PDO::FETCH_ASSOC tells PDO to return the result as an associative array.

The array keys will match your column names. If your table contains columns 'email' and 'password', the array will be structured like:

Array
(
    [email] => '[email protected]'
    [password] => 'yourpassword'
)

To read data from the 'email' column, do:

$user['email'];

and for 'password':

$user['password'];

As an alternative to @Eric Lease's decorator, which unfortunately doesn't work using --aot (and thus --prod) builds, I resorted to using a service which exposes all my application's enums. Just need to publicly inject that into each component which requires it, under an easy name, after which you can access the enums in your views. E.g.:

Service

import { Injectable } from '@angular/core';
import { MyEnumType } from './app.enums';

@Injectable()
export class EnumsService {
  MyEnumType = MyEnumType;
  // ...
}

Don't forget to include it in your module's provider list.

Component class

export class MyComponent {
  constructor(public enums: EnumsService) {}
  @Input() public someProperty: MyEnumType;

  // ...
}

Component html

<div *ngIf="someProperty === enums.MyEnumType.SomeValue">Match!</div>

Error 1215 is an annoying one. Explosion Pill's answer covers the basics. You want to make sure to start from there. However, there are more, much more subtle cases to look out for:

For example, when you try to link up PRIMARY KEYs of different tables, make sure to provide proper ON UPDATE and ON DELETE options. E.g.:

...
PRIMARY KEY (`id`),
FOREIGN KEY (`id`) REFERENCES `t` (`other_id`) ON DELETE SET NULL
....

won't fly, because PRIMARY KEYs (such as id) can't be NULL.

I am sure, there are even more, similarly subtle issues when adding these sort of constraints, which is why when coming across constraint errors, always make sure that the constraints and their implications make sense in your current context. Good luck with your error 1215!

This is a simple html file "demo.htm" stored in the same folder as the node.js file.

<!DOCTYPE html>
<html>
  <body>
    <h1>Heading</h1>
    <p>Paragraph.</p>
  </body>
</html>

Below is the node.js file to call this html file.

var http = require('http');
var fs = require('fs');

var server = http.createServer(function(req, resp){
  // Print the name of the file for which request is made.
  console.log("Request for demo file received.");
  fs.readFile("Documents/nodejs/demo.html",function(error, data){
    if (error) {
      resp.writeHead(404);
      resp.write('Contents you are looking for-not found');
      resp.end();
    }  else {
      resp.writeHead(200, {
        'Content-Type': 'text/html'
      });
      resp.write(data.toString());
      resp.end();
    }
  });
});

server.listen(8081, '127.0.0.1');

console.log('Server running at http://127.0.0.1:8081/');

Intiate the above nodejs file in command prompt and the message "Server running at http://127.0.0.1:8081/" is displayed.Now in your browser type "http://127.0.0.1:8081/demo.html".

I tried a slightly different approach to prevent UIWebView objects from scrolling and bouncing: adding a gesture recognizer to override other gestures.

It seems, UIWebView or its scroller subview uses its own pan gesture recognizer to detect user scrolling. But according to Apple's documentation there is a legitimate way of overriding one gesture recognizer with another. UIGestureRecognizerDelegate protocol has a method gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: - which allows to control the behavior of any colliding gesture recognizers.

So, what I did was

in the view controller's viewDidLoad method:

// Install a pan gesture recognizer                                                                                        // We ignore all the touches except the first and try to prevent other pan gestures                                                     
// by registering this object as the recognizer's delegate                                                                                        
UIPanGestureRecognizer *recognizer;                                                                                                               
recognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanFrom:)];                                                   
recognizer.delegate = self;                                                                                                                       
recognizer.maximumNumberOfTouches = 1;                                                                                                            
[self.view addGestureRecognizer:recognizer];                                                                                                          
self.panGestureFixer = recognizer;                                                                                                                  
[recognizer release]; 

then, the gesture override method:

// Control gestures precedence                                                                                                                            
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer                                                                                        
        shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer                                                  
{                                                                                                                                                         
        // Prevent all panning gestures (which do nothing but scroll webViews, something we want to disable in                                          
        // the most painless way)                                                                                                                         
        if ([otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]])                                                                        
        {
            // Just disable every other pan gesture recognizer right away                                                                             
            otherGestureRecognizer.enabled = FALSE;
        }                                                                                                                                                  
        return NO;                                                                                                                                        
}              

Of course, this delegate method can me more complex in a real application - we may disable other recognizers selectively, analyzing otherGestureRecognizer.view and making decision based on what view it is.

And, finally, for the sake of completeness, the method we registered as a pan handler:

- (void)handlePanFrom:(UIPanGestureRecognizer *)recognizer 
{ 
    // do nothing as of yet
}

it can be empty if all we want is to cancel web views' scrolling and bouncing, or it can contain our own code to implement the kind of pan motions and animations we really want...

So far I'm just experimenting with all this stuff, and it seems to be working more or less as I want it. I haven't tried to submit any apps to iStore yet, though. But I believe I haven't used anything undocumented so far... If anyone finds it otherwise, please inform me.

Here's some pseudocode - you can cut same recursive calls by storing the values for each call as you go and before recursive call checking if the call value is already present.

The following algorithm will have all the subsets excluding the empty set.

list * subsets(string s, list * v) {

    if(s.length() == 1) {
        list.add(s);    
        return v;
    }
    else
    {
        list * temp = subsets(s[1 to length-1], v);
        int length = temp->size();

        for(int i=0;i<length;i++) {
            temp.add(s[0]+temp[i]);
        }

        list.add(s[0]);
        return temp;
    }
}

So, for example if s = "123" then output is:

1
2
3
12
13
23
123

JavaScript is a dynamically typed language. This means that you never need to declare the type of a function argument (or any other variable). So, your code will work as long as arrayP is an array and contains elements with a value property.

I wanted to create a new enumerable object or list and be able to add to it.

This comment changes everything. You can't add to a generic IEnumerable<T>. If you want to stay with the interfaces in System.Collections.Generic, you need to use a class that implements ICollection<T> like List<T>.

make sure you use the POST to insert the data. Actually you were using GET.

The problem is your plugin. To solve this is to only enter this address:

If you want search for sensitive data in order to remove it from your git history (which is the reason why I landed here), there are tools for that. Github as a dedicated help page for that issue.

Here is the gist of the article:

The BFG Repo-Cleaner is a faster, simpler alternative to git filter-branch for removing unwanted data. For example, to remove your file with sensitive data and leave your latest commit untouched), run:

bfg --delete-files YOUR-FILE-WITH-SENSITIVE-DATA

To replace all text listed in passwords.txt wherever it can be found in your repository's history, run:

bfg --replace-text passwords.txt

See the BFG Repo-Cleaner's documentation for full usage and download instructions.

I know this is an old question, but just in case you are trying to do the same thing in ASP.NET Core, here is how you can create the UrlHelper inside an action:

var urlHelper = new UrlHelper(this.ControllerContext);

Or, you could just use the Controller.Url property if you inherit from Controller.

If you have a checkbox in your html something like:

<input id="conducted" type = "checkbox" name="party" value="0">

and you want to add an EventListener to this checkbox using javascript, in your associated js file, you can do as follows:

checkbox = document.getElementById('conducted');

checkbox.addEventListener('change', e => {

    if(e.target.checked){
        //do something
    }

});

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

System.ArgumentNullException: Value cannot be null. Parameter name: value

This error message is not very helpful!

You can get this error in many different ways. The error may not always be with the parameter name: value. It could be whatever parameter name is being passed into a function.

As a generic way to solve this, look at the stack trace or call stack:

Test method GetApiModel threw exception: 
System.ArgumentNullException: Value cannot be null.
Parameter name: value
    at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings)

You can see that the parameter name value is the first parameter for DeserializeObject. This lead me to check my AutoMapper mapping where we are deserializing a JSON string. That string is null in my database.

You can change the code to check for null.

Here is the complete process to create a local repo and push the changes to new remote branch

1. Creating local repository:-

   Initially user may have created the local git repository.

   $ git init :- This will make the local folder as Git repository,

2. Link the remote branch:-

   Now challenge is associate the local git repository with remote master branch.

   $ git remote add RepoName RepoURL

   usage: git remote add []

3. Test the Remote

   $ git remote show --->Display the remote name

   $ git remote -v --->Display the remote branches

4. Now Push to remote

   $git add . ----> Add all the files and folder as git staged'

   $git commit -m "Your Commit Message" - - - >Commit the message

   $git push - - - - >Push the changes to the upstream

SELECT firstName, ID, LastName from tableName GROUP BY firstName

JSON.stringify(data).length return string length not Object length, you can use Object.keys.

<% for(var i=0; i < Object.keys(data).length ; i++) {%>

open up console and navigate to bin folder and run

JBOSS_HOME/bin > stanalone.sh

Once it is up and running just copy past your war file in

standalone/deployments folder

Thats probably it for jboss 7.1

From your pom.xml, try to remove spring repository entries, per default will download from maven repository. I have tried with 1.5.6.RELEASE and worked very well.

module.exports is the object that's actually returned as the result of a require call.

The exports variable is initially set to that same object (i.e. it's a shorthand "alias"), so in the module code you would usually write something like this:

let myFunc1 = function() { ... };
let myFunc2 = function() { ... };
exports.myFunc1 = myFunc1;
exports.myFunc2 = myFunc2;

to export (or "expose") the internally scoped functions myFunc1 and myFunc2.

And in the calling code you would use:

const m = require('./mymodule');
m.myFunc1();

where the last line shows how the result of require is (usually) just a plain object whose properties may be accessed.

NB: if you overwrite exports then it will no longer refer to module.exports. So if you wish to assign a new object (or a function reference) to exports then you should also assign that new object to module.exports

It's worth noting that the name added to the exports object does not have to be the same as the module's internally scoped name for the value that you're adding, so you could have:

let myVeryLongInternalName = function() { ... };
exports.shortName = myVeryLongInternalName;
// add other objects, functions, as required

followed by:

const m = require('./mymodule');
m.shortName(); // invokes module.myVeryLongInternalName

In Python3, since Python 3.2 there is a new approach to reach the same result, that I personally prefer to the traditional thread creation/start/join, package concurrent.futures: https://docs.python.org/3/library/concurrent.futures.html

Using a ThreadPoolExecutor the code would be:

from concurrent.futures.thread import ThreadPoolExecutor
import time

def call_script(ordinal, arg):
    print('Thread', ordinal, 'argument:', arg)
    time.sleep(2)
    print('Thread', ordinal, 'Finished')

args = ['argumentsA', 'argumentsB', 'argumentsC']

with ThreadPoolExecutor(max_workers=2) as executor:
    ordinal = 1
    for arg in args:
        executor.submit(call_script, ordinal, arg)
        ordinal += 1
print('All tasks has been finished')

The output of the previous code is something like:

Thread 1 argument: argumentsA
Thread 2 argument: argumentsB
Thread 1 Finished
Thread 2 Finished
Thread 3 argument: argumentsC
Thread 3 Finished
All tasks has been finished

One of the advantages is that you can control the throughput setting the max concurrent workers.

Apple's "Build Setting Reference" documentation for what's officially documented (or as rjstelling's answer shows, use env in a build script to see what Xcode actually passes you.

In case the above link changes, Google search for: "build setting reference" site:developer.apple.com

Here you go:

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;

Type type = new TypeToken<Map<String, String>>(){}.getType();
Map<String, String> myMap = gson.fromJson("{'k1':'apple','k2':'orange'}", type);

can try this too ...

router.push({ name: 'myRoute' })

For clarity, I thought that a direct example of grabbing onto a resource can be shown from the following that I think contributes to the response for this question with a quick direct example.

private MenuItem menuItem_;

@Override
public boolean onCreateOptionsMenu(Menu menuF) 
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_layout, menuF);
    menuItem_ = menuF.findItem(R.id.menu_item_identifier);
    return true;
}

In this case you hold onto a MenuItem reference at the beginning and then change the state of it (for icon state changes for example) at a later given point in time.

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

For port 80, the command would be : netstat -an | find "80" For port n, the command would be : netstat -an | find "n"

Here, netstat is the instruction to your machine

-a : Displays all connections and listening ports -n : Displays all address and instructions in numerical format (This is required because output from -a can contain machine names)

Then, a find command to "Pattern Match" the output of previous command.

Use LIMIT with two parameters. For example, to return results 11-60 (where result 1 is the first row), use:

SELECT * FROM foo LIMIT 10, 50

For a solution to return all results, see Thomas' answer.

Instead of redirecting System.out, I would refactor the class that uses System.out.println() by passing a PrintStream as a collaborator and then using System.out in production and a Test Spy in the test. That is, use Dependency Injection to eliminate the direct use of the standard output stream.

In Production

ConsoleWriter writer = new ConsoleWriter(System.out));

In the Test

ByteArrayOutputStream outSpy = new ByteArrayOutputStream();
ConsoleWriter writer = new ConsoleWriter(new PrintStream(outSpy));
writer.printSomething();
assertThat(outSpy.toString(), is("expected output"));

Discussion

This way the class under test becomes testable by a simple refactoring, without having the need for indirect redirection of the standard output or obscure interception with a system rule.

Another fairly simple way to go about this is to make a method like this:

def _write_frame_to_new_sheet(path_to_file=None, sheet_name='sheet', data_frame=None):
    book = None
    try:
        book = load_workbook(path_to_file)
    except Exception:
        logging.debug('Creating new workbook at %s', path_to_file)
    with pd.ExcelWriter(path_to_file, engine='openpyxl') as writer:
        if book is not None:
            writer.book = book
        data_frame.to_excel(writer, sheet_name, index=False)

The idea here is to load the workbook at path_to_file if it exists and then append the data_frame as a new sheet with sheet_name. If the workbook does not exist, it is created. It seems that neither openpyxl or xlsxwriter append, so as in the example by @Stefano above, you really have to load and then rewrite to append.

Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/

Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):

=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))

To translate your specific example, you would use:

=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))

Note that the link you provided does is not an HTML page, but rather a JSON document. The formatting is done by the browser.

You have to decide if:

1. You want to show the raw JSON (not an HTML page), as in your example
2. Show an HTML page with formatted JSON

If you want 1., just tell your application to render a response body with the JSON, set the MIME type (application/json), etc. In this case, formatting is dealt by the browser (and/or browser plugins)

If 2., it's a matter of rendering a simple minimal HTML page with the JSON where you can highlight it in several ways:

• server-side, depending on your stack. There are solutions for almost every language
• client-side with Javascript highlight libraries.

If you give more details about your stack, it's easier to provide examples or resources.

EDIT: For client side JS highlighting you can try higlight.js, for instance.

This is the shorter version: Basically I try to get the difference between the post timestamp with the Date() now.

// MARK: - UPDATE Time Stamp
static func updateTimeStampPost(postTimeStamp: Date?, _ completion: (_ finalString: String?) -> Void) {
    // date in the current state
    let date = Date()
    let dateComponentFormatter = DateComponentsFormatter()

    // change the styling date, wether second minute or hour
    dateComponentFormatter.unitsStyle = .abbreviated
    dateComponentFormatter.allowedUnits = [.second, .minute, .hour, .day, .weekOfMonth]
    dateComponentFormatter.maximumUnitCount = 1

    // return the date new format as a string in the completion
    completion(dateComponentFormatter.string(from: postTimeStamp!, to: date))
}

The fundamental difference in most programming languages is that unless the unexpected happens a for loop will always repeat n times or until a break statement, (which may be conditional), is met then finish with a while loop it may repeat 0 times, 1, more or even forever, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while loop, (or repeat until), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).

It is worth noting that in Python a for or while statement can have break, continue and else statements where:

• break - terminates the loop
• continue - moves on to the next time around the loop without executing following code this time around
• else - is executed if the loop completed without any break statements being executed.

N.B. In the now unsupported Python 2 range produced a list of integers but you could use xrange to use an iterator. In Python 3 range returns an iterator.

So the answer to your question is 'it all depends on what you are trying to do'!

Try using rowMeans:

z$mean=rowMeans(z[,c("x", "y")], na.rm=TRUE)

  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4
