Programming WCF Services

Windows Communication Foundation (WCF) is Microsoft’s unified programming model for building service-oriented applications. In one of my other tutorial Introducing Windows Communication Foundation (WCF), I have presented detailed overview of WCF key features, important concepts and architecture.  In this tutorial, I will give you exposure to the WCF programming experience by giving you basic understanding of the steps required to create WCF service and client application.

Introducing Windows Communication Foundation (WCF)

Windows Communication Foundation (WCF) is a framework designed for software and web developers who want to develop distributed service-oriented applications. WCF allows developers to create, host, consume and secure services using Microsoft platform in a most productive way so that developers can focus on their implementation rather than communication protocols and low level messaging details. In this tutorial, I will cover the basic concepts needed to work with WCF services. You will be able to create and consume services using the most commonly used features of WCF technology.

Using Multiple Programming Languages in ASP.NET Website

ASP.NET websites do not allow you to use multiple programming languages such as C# and Visual Basic in the App_Code folder of the website project. If you are creating a C# web site and you have copied a Visual Basic source file in App_Code folder, you won’t be able to compile your ASP.NET website. Off course, if it is a small source file, then you can convert it into C# source code either yourself or by using any code converter but it is time wasting practice if you have a large file or you want to use multiple source files. In this tutorial, I will show you how you can use multiple programming languages source files in a single website project by just doing some simple modifications in the configuration settings of the website.

Customizing Android ListView Items with Custom ArrayAdapter

For real-world commercial mobile applications, the default look and feel of the Android ListView is not very attractive. It only renders a simple String in every ListView row using the internal TextView control. For most applications, you want to create an interface that is more graphically rich and visually pleasing to the user. Luckily, ListView is very powerful control and with the help of custom item layouts, it can be customized to suit your needs easily. In this tutorial, I will show you how you can create custom ListView items with icons, custom header layout and how you can use custom ArrayAdapter to glue everything together. I will also show you some performance improvement tips you can use to optimize the memory usage of your ListView control.

Handling Android ListView onItemClick Event

Android ListView control is designed to display a list of items to the user and the most common action users perform with the ListView is the item selection by just tapping any particular item in the ListView. ListView allows developers to handle user tapping by attaching the OnItemClickListener and overriding the onItemClick event. In most cases, when user click any item in the ListView, a new android activity opens that shows the details related to the selected item. To implement such scenario the knowledge of Android Intents and activity to activity communication is required. I will show you that in my future tutorials. In this tutorial, I will demonstrate you how you can handle the click events in ListView.

Binding Android ListView with Custom Objects using ArrayAdapter

In my previous tutorial Binding Android ListView with String Array using ArrayAdapter, I have shown you how you can bind the Android ListView control with an array of String objects. Although it was a very simple implementation, but it was useful for those who are just starting learning Android application development. As an Android developer, soon you will realize that showing simple Strings in the ListView is not what you exactly want in real-world  Android Apps, and you will often find yourself dealing with collections  of custom Java objects. In this tutorial, I have decided to show you how you can bind Android ListView with custom objects using ArrayAdapter.
