What is the purpose of using Custom Web Form Controls in building Web applications? Be sure to explain their role and give an example to explain your answer.
Custom Web Form Controls allow the developer to create reusable components, which are essentially reusable parts of an ASPX page, that can be part of other ASPX pages and other Web applications. For example, many Web applications utilize Shopping Carts that contain a set of controls that handle the display of products in the cart and a set of controls that allow the user to manage (add/remove, edit) the cart. Instead of recreating the GUI and programming the functionality of a shopping cart on many different Web applications, the programmer can create a Custom Web Form Control that handles the shopping cart display and operations, and reuse it in other pages or Web applications.

Explain the role of serialization and deserialization in Web APIs or an ASMX Web Service. Make sure your answer explains how it is specifically used with Web APIs and give an example. You answer should discuss the proper terminologies and technologies we discussed in class.
Your Answer: WEB API default serilization is JSON or XML, when a WEB API is called, it grab the information and serialize the information and that information could be string, object, etc, etc and that information come back as JSON or XML (as a default). After that we have to deserilization the JSON or XML file to get the actual values to use it. A good example if I write a fucntion to call the Web API by creating a string URL. I use DataStream and DataReader to read the JSON or XML file from the web API. I then deserialize that information into either a string, object, or etc etc and uses it.
Write the necessary code to call and execute the stored procedure in C#. Use the following code to complete this question. // Stored Procedure CodeCREATE PROCEDURE GetProductAS SELECT ProductID, Title, Description, Price FROM Products // C# Code DBConnect db = new DBConnection();SqlCommand myCommand = new SqlCommand();
Your Answer: myCommand.CommandType = CommandType.StoredProcedure; myCommand.CommandText = "GetProduct"; db.GetDataSetUsingCmdObj(myCommand);
