HTTP Error 404.0 - Not Found in MVC

Image
The Resource you are looking for has been removed, had its name changed, or is temporarily unavailable. I saw this error today while working on a MVC Web Project, this is a common error we get while running website and performing any CRUD (Create, Read, Update, Delete) operation. Stackoverflow is full of such queries so I decided to post the fix here. You might not find it useful for your case but I think majority of requests can be satisfied.

Managed and Unmanaged Code

Managed and Unmanaged Code Managed Languages made of assemblies (EXE and DLLs) containing code written in intermediate language (IL). This code is not machine code. When the application runs, the code is executed by the .NET runtime, which in turn executes the corresponding machine code. The code is managed by the .NET runtime. Managed code is typically slower than machine code, because of the additional layer between the code and the machine. However, the .NET framework offers many advantages over unmanaged code: ·    A huge number of built-in high level libraries. ·    Stable code has fewer errors ·    Errors will be found when you compile the application, instead of appearing at runtime.   Traditional Windows Applications were (and still they are used somewhere) often programmed using a framework known as MCF (Microsoft Foundation Classes). In this framework code compiles directly to machine code, which is referred as low-level, and very near to machine code.

Testing Website using SSL on Localhost (IIS)

Image
Introduction SSL (Secure Socket Layer) is a cryptographic protocol developed by Netscape to provide communications security on internet. Cryptographic technology uses two keys to encrypt data, one for public (public key) and another for recipient (secret key). SSL enabled website communicates with web server by using security channel (secret key) that prevents tempering, eavesdropping (or simply say hacking). Mostly probably SSL is used on login section, payment system, online banking system etc that is very sensitive information for organization. When we enable the SSL for website URL will start with https:// instead of http://. Requirements To test this, you should have IIS installed. No need of extra software like Visual Studio or any other website development kit because only a single HTML file can be tested. Follow the steps to enable SSL on Windows Server 2008 R2 Operating System; another Operating System may have little difference. Step 1 Open IIS Manger and

Web Services

Image
Introduction   Download As name "Web Services" suggests, it is a method of communication between two electronic devices over the web (internet). A web service is not a website that a human reads. It is not anything with which an end user would directly interact. A web service is a standard platform for building interoperable distributed applications. It allows you as a developer, to interact with other information providers without worrying about what they are running either at the backend or even their front-end. Points to remember * WS are small units of code. * WS are small unit of codes that is designed to handle limited set of tasks. For example, online payment system communicates using Web Services. * WS are independent of OS and Programming Languages. * WS are not limited to OS type or Programming Languages as it communicates using open protocol systems. * WS are designed to handle

Reading Data From Database and Display in Label or other control

Reading Data From Database and Display in Label or other control DataSet dtst = new DataSet();         SqlConnection sqlCon = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);         string strSql = "SELECT FieldName FROM TableName WHERE FieldName LIKE '" + prefixText + "%' ";         SqlCommand sqlComd = new SqlCommand(strSql, sqlCon);         sqlCon.Open();         SqlDataAdapter sqlAdpt = new SqlDataAdapter();         sqlAdpt.SelectCommand = sqlComd;         sqlAdpt.Fill(dtst);         string[] cntName = new string[dtst.Tables[0].Rows.Count];         int i = 0;         try         {             foreach (DataRow rdr in dtst.Tables[0].Rows)             {                 cntName.SetValue(rdr["CountryName"].ToString(), i);                 i++;             }         }         catch { }         finally         {             sqlCon.Close();         }         return

Switch Case Fall-Through Rules in .NET

Because you cannot accidentally fall through from one case label to the next if there is any intervening code, you can freely rearrange the sections of a switch statement without affecting its meaning (including the default label, which by convention is usually placed as the last label but does not have to be). C and C++ programmers should note that the break statement is mandatory for every case in a switch statement (even the default case)  This requirement is a good thing; it is common in C or C++ programs to forget the break statement, allowing execution to fall through to the next label and leading to bugs that are difficult to spot. If you really want to, you can mimic C/C++ fall-through in C# by using a goto statement to go to the following case or default label. Using goto in general is not recommended, though, and this book does not show you how to do it.

Generating Method Stub in Visual Studio

Image
Introduction This post is for those who still don't know Method Stub or using a boring style method writing technique. Visual Studio IDE has a great feature named Generate Method Stub which let generate Method Stub automatically. What is Method Stub? Method Stub is a feature that helps developer to generate the method codes by just clicking a button. Let's look what MSDN says :- Generate Method Stub is an IntelliSense Automatic Code Generation feature that provides an easy way to have Visual Studio create a new method declaration at the time you are writing a method call. Visual Studio infers the declaration from the call. Some programming styles, such as test-driven development, suggest that you should consume before you define. That way, it is easier to figure out the form of the API that you are developing. You can use IntelliSense to program in that style. Using the Generate Method Stub operation, you avoid defining everything before you consume i
