Quick way to debug/display MVC or WebForms session data on live server without deploying

joe912 Uncategorized

This works for both MVC and web forms.

Create a text file called for example “test.aspx”. Edit to have content shown below. Copy the file to root folder of your web site then browse : http://yoursite.com/test.aspx


   
<%@ Language=C# %>
<html>
   <script runat="server" language="C#">
   void MyButton_OnClick(Object sender, EventArgs e)
   {
      lblSessionId.Text = "Session ID : " + Session.SessionID + " @ " + DateTime.Now.ToLongTimeString();
 	lblThreadCultureName.Text = "Thread culture name : " + System.Threading.Thread.CurrentThread.CurrentCulture.DisplayName;
 	lblThreadUICultureName.Text = "Thread UI culture name : " + System.Threading.Thread.CurrentThread.CurrentUICulture.DisplayName;
   }
   </script>
   <body>
      <form id="MyForm" runat="server">
         <asp:button id="MyButton" text="Click here to display session ID" OnClick="MyButton_OnClick" runat="server"></asp:button>
         <asp:label id="lblSessionId" runat="server"></asp:label><br/>
          <asp:label id="lblThreadCultureName" runat="server"></asp:label><br/>
         <asp:label id="lblThreadUICultureName" runat="server"></asp:label><br/>

      </form>
   </body>
</html>

C# Example of getting the index of items in a LINQ Select query

    class Program
    {
        private static List<Book> _books  = new List<Book>
        {
            new Book {Id = 9999, Title = "Book A" },
            new Book {Id = 22, Title = "Book B" },
            new Book {Id = 3876, Title = "Book C" },
        };

        static void Main(string[] args)
        {
            // In the LINQ lambda the second parameter is the index 
            var bookList = Books.Select((b, i) => new { Index = i, Book = b }).ToList();

            foreach (var bookWithIndex in bookList)
            {
                Console.WriteLine(string.Format("Book Id: {0}, Title : {1}, Index: {2}", 
                    bookWithIndex.Book.Id, 
                    bookWithIndex.Book.Title, 
                    bookWithIndex.Index));
            }

            Console.ReadKey();
        }

        static IEnumerable<Book> Books
        {
            get
            {
                foreach (var book in _books)
                {
                    yield return book;
                }
            }
        }
    }

    public class Book
    { 
        public int Id { get; set; }
        public string Title { get; set; }
    }

Installing Umbraco – login failed for user admin

joe912 Uncategorized

On creating a new Umbraco site the wizard prompts you to create an administrator account.  It prompts for:

  • Name                       – you enter [admin]
  • Email                        – you enter [john@test.com]
  • Password                 – you enter [testing123]

Then click “install”

The site loads.  Append “/umbraco” to the site’s url and you can enter the backend.

You logout.

You try to login with the following details:

Username: admin

Password: testing123

You get an error – login failed for user admin.    WTF???

Ok try this:

Username: john@test.com

Password: testing123

You’re in!

To be fair when entering the administrator username and password it does say underneath that “Your email will be used as your login”.  But still shite in my opinion.

Octopus Deploy – promoting releases with different configuration

joe912 Dev Ops

Using Octopus Deploy v3.x it is possible to promote a release to different environments using different configuration for each environment.

For example on DEV it is possible to use the web.dev.config transform and a IIS host header of mysite.dev. On QA the web.qa.config transform would be used and the IIS host header would be mysite.qa.

Create a step to deploy the web site to IIS and enable it for DEV and QA environments:

Octopus1

Create environment specific variables for web.config transform and host header:

Octopus2

To transform web.dev.config and web.qa.config to web.config depending on the environment then edit the “Additional Transforms” in the “Configuration Transforms” section like this:

Octopus3

To use the host header variable edit the “IIS Bindings” section like this:

Octopus4
