Those 2 urls are not the same!

Top Tip - look at T4MVC

@Html.ActionLink("Delete Dinner", "Delete", "Dinners", new { id = Model.DinnerID }, null)

T4MVC lets you write

@Html.ActionLink("Delete Dinner", MVC.Dinners.Delete(Model.DinnerID))

Have a look at T4MVC and @Url.Action

Some more tinkerings - might also help.

Look at the DoSomething methods. In OO you shouldn't be asking if something is of a certain type and then acting accordingly, much better to use polymorphism as in the DoSomething Example.

void Main()
{
    var game = new Game();

    Player dave = new Player { Name = "Dave" };
    Player sarah = new Player { Name = "Sarah" };
    Computer mac = new Computer { Name = "Mac" };

    game.PlayerList.Add(dave);
    game.PlayerList.Add(sarah);
    game.PlayerList.Add(mac);

    foreach (var player in game.PlayerList)
    {
        Console.WriteLine(player.Name + " is a computer = " + (player.GetType() == typeof(Computer)));
    }

    Console.WriteLine();

    bool isCurrentPlayerComputer;

    game.CurrentPlayer = mac;   
    isCurrentPlayerComputer =  game.CurrentPlayer as Computer != null;  
    Console.WriteLine("Current Player {0} is a computer? {1}", game.CurrentPlayer.Name, isCurrentPlayerComputer);

    game.CurrentPlayer = dave;  
    isCurrentPlayerComputer =  game.CurrentPlayer as Computer != null;  
    Console.WriteLine("Current Player {0} is a computer? {1}", game.CurrentPlayer.Name, isCurrentPlayerComputer);

    Console.WriteLine();

    foreach (var player in game.PlayerList)
    {
        player.DoSomething();
    }   
}

public class Game
{
    public Game()
    {
        PlayerList = new List<Player>();
    }

    public List<Player> PlayerList { get; set; }

    public Player CurrentPlayer { get; set; }
}

public class Player
{
    public string Name { get; set; }

    public virtual void DoSomething()
    {
        Console.WriteLine("Doing something in the style of a player");
    }
}

public class Computer: Player
{
    public override void DoSomething()
    {
        Console.WriteLine("Doing something in the style of a computer");
    }
}

I'm not really sure what you are after but I did some tinkering - might help, might not.

void Main()
{
    var game = new Game();

    Player dave = new Player { Name = "Dave" };
    Player sarah = new Player { Name = "Sarah" };
    Computer mac = new Computer { Name = "Mac" };

    game.PlayerList.Add(dave);
    game.PlayerList.Add(sarah);
    game.PlayerList.Add(mac);

    foreach (var player in game.PlayerList)
    {
        Console.WriteLine(player.Name + " is a computer = " + (player.GetType() == typeof(Computer)));
    }
}

public class Game
{
    public Game()
    {
        PlayerList = new List<Player>();
    }

    public List<Player> PlayerList { get; set; }

    public Player CurrentPlayer { get; set; }
}

public class Player
{
    public string Name { get; set; }
}

public class Computer: Player
{

}

public class MyModel
{
    public Model1 Model1 { get; set;}
    public Model2 Model2 { get; set;}
}

Use an absolute network path?

I think bulk uploads look for files on the machine SQL is running on.

Does it exist on the database server?

It is shared because you used "static"

Not sure if this is right but try emoving brackets:

document.getElementById('clickMe').onclick = testOne;

In this case Contact is class. It represents a contact in my domain.

It would be a User, Person, Company, Book, Item etc

I have made the assumption you are using Entity Framework - is this in fact the case?

    public class Contact
    {
        public int Id { get; set;

        public string Firstname { get; set; }

        public string Surname { get; set; }

        public string Company { get; set; }

        public string Telephone { get; set; }

        public string Mobile { get; set; }
    }

1. Get the current item from the database

2. Update just the properties you want to change

3. Use the Repository Pattern to execute code simillar to that below

       public void Update(Contact contact)
       {
           using (var context = new EfContext())
           {
               Contact existingContact = context.Contacts.Single(c => c.Id == contact.Id);
   
               context.Entry(existingContact).CurrentValues.SetValues(contact);
   
               context.SaveChanges();
           }
       }
   

What actually happens?

There are various ways. BackgroundWorker is probably best.

What is the code doing? If it is on the main thread and it is doing a lot it can freeze the UI. Consider running the code on another thread.

I have that too.

You can set this in your web.config eg:

  <system.web>
    <customErrors mode="Off" ></customErrors>
    <compilation debug="true" targetFramework="4.5" ></compilation>
    <httpRuntime targetFramework="4.5" ></httpRuntime>
    <authentication mode="Forms">
      <forms loginUrl="~/Account/Login" timeout="2880" ></forms>
    </authentication>
    <pages>
      <namespaces>
        <add namespace="System.Web.Helpers" ></add>
        <add namespace="System.Web.Mvc" ></add>
        <add namespace="System.Web.Mvc.Ajax" ></add>
        <add namespace="System.Web.Mvc.Html" ></add>
        <add namespace="System.Web.Optimization" ></add>
        <add namespace="System.Web.Routing" ></add>
        <add namespace="System.Web.WebPages" ></add>
      </namespaces>
    </pages>
  </system.web>

Should $ITEM be inside the speech marks?

Also it also seems FF doesn't like "scroll" - try renaming your function to something else.

Actually it might be that you closed your a tag twice.

Remove the / at the end of the first part of the a tag.

Works for me: https://jsfiddle.net/xyt0527j/

FF Version 33.1.1

Here's my go:

    <script>
        function CustomDate()
        {
            this.date = new Date();  
            this.dayPart = this.date.getHours() < 12 ? "AM" : "PM";

            this.toString = function()
            {
                return this.date.getMonth() + "/" + this.date.getDate() + "/" + this.date.getFullYear()
                    + " - " + this.date.getHours( ) + ":" + this.date.getMinutes()
                    + ":" + this.date.getSeconds() + " " + this.dayPart;
            };
        }

        var d = new CustomDate();

        alert(d);
    </script>

Can you be a little more specific.

For example have you already

a) Created a MVC project?
b) Created a Controller?
c) Created a Controller Action?
d) Created a View

And so on...

What do you mean by manually?

If you are iterating over a collection which has enumerable properties then you can use foreach. For example:

foreach (var customer in customers)
{
    Console.WriteLine(customer.FirstName + " " + customer.LastName);
}

You could also achieve the same with a for loop:

for (var i = 0; i < customers.Count; i ++)
{
    Console.WriteLine(customers[i].FirstName + " " + customers[i].LastName);
}

In this case the first is more readable and easier to code right?

If you want to do a loop for some other reason though such as not iterating over a collectio but doing something x times then maybe a for loop is better. Also a for loop gives you access to the number of iterations you are on. So if you want to output:

1 Dave Amour
2 Fred Bloggs
3 Sarah Smith

Then there may be a case for using a for loop - it's up to you to make that call though.

Note - in order to be able to use foreach then the collection you are iterating over must implement IEnumberable or IEumerable<T>. Almost all collections do.

Here is a console app you can tinker with.

using System;
using System.Collections.Generic;

namespace ForeachVerusForLoop
{
    class Program
    {
        static void Main(string[] args)
        {
            var customers = GetCustomers();

            foreach (var customer in customers)
            {
                Console.WriteLine(customer.FirstName + " " + customer.LastName);
            }

            for (var i = 0; i < customers.Count; i ++)
            {
                Console.WriteLine(customers[i].FirstName + " " + customers[i].LastName);
            }

            Console.ReadKey();
        }

        static List<Customer> …

Delete Line 30, 31 and 33

Move Line 32 to after your loop

Change "else if ( Number <0)" to "else" - no need to check as it must be less than 0

That's a bootstrap menu.

What does it return then?

Is it working or Erroring?

In what way is it not working?

That already is ajax. Can you be more specific?

You can call a function from anywhere.

You can call a function from main and this function inside it's body can call other functions. Those other functions can also call functions. This is how you build up complex applications.

A recursive function is one that calls itself. This is often used for things like traversing a directory structure or things of that nature.

There are many good tutorials on this.

Check out the following for example.

http://www.zentut.com/c-tutorial/c-recursive-function/
http://www.programiz.com/c-programming/c-recursion
http://www.cprogramming.com/tutorial/lesson16.html

Hope that helps.

Ok cool, this is what I said right from the start!

Show me the design of the table in the GUI please.

Here is one way.

using System;
using System.Linq;

namespace ForEach
{
    class Program
    {
        static void Main(string[] args)
        {
            const string s = "111\n222\n333";

            foreach (var line in s.Split('\n').ToArray())
            {
                if (line == "333")
                {
                    Console.WriteLine("Found the 333 number");
                }
            }

            Console.ReadKey();

        }
    }
}

This should be really easy and to repeat my first reply to this thread, just debug the code and see what is happening.

Have you done this or not? It should be the very first thing you should ever do when something like this doesn't work.

Sorry I thought you said it was working now? Is it working or not?

Did you change the data being insrted/updated?

This error message means you are trying to insert or update data which is too long.

Eg trying to enter "Dave" into a database column defined as only being 3 characters in length.

Decrease your data or increase your column width.

It just means you are declaring a variable called flag and giving it a value of 1 or 0. This will presumably be used elsewhere in the code to keep a track of the state of something. It is also probably boolean in nature.

Read a book, watch some videos, take a class, find a provate tutor, read a website.

The above advice also applies to T in HowToLearn<T>

Hi Thomas

I don't code in C++ but in C# we would do this with a static property.

I do think you may be misunderstanding inheritance.

Could you post the simplest version possible of code needed to demonstrate what you are trying to achieve and I can comment further.

Its badly formed, should be />

:)

Can't you just debug it and see. Do you know how to debug and step through code?

Ok you will need image recognition software then in case someone tries to inject some brie or red leicester by mistake.

What is Foto - is that some kind of goats cheese?

Ok I am going to attempt to solve this even without seeing your code even though that goes against my scientific nature.

Do you by any chance have JavaScript thinking your variables are strings and not numbers?

Did you do something like this maybe?

http://www.paxium.co.uk/content/daniweb/ifstatement.html

<body>
    <script>
        $(document).ready(function()
        {
            var maxGrootte = $("#t1").val();
            var minGrootte = $("#t2").val();

            if(maxGrootte < minGrootte)
            {
                alert(maxGrootte + " is less than " + minGrootte);
            }
            else
            {
                alert(maxGrootte + " is not less than " + minGrootte);
            }            
        });
    </script>

    <input type="text" id="t1" value="12" />
    <input type="text" id="t2" value="5" />
</body>

Show me your code though please - there is something wrong with it but I can't fix it unless you show it to me.

It is far more likeley that you have done something wrong.

For example you have two spellings of minGrooote there. One with one t and one with two ts.

Can you show me the code where you declare and assign values to these two variables?

Can you try with a different browser?

Also can you see any of these sites?
