Communicating from Dynamics CRM to BizTalk Server

by Richard Seroter | July 2011 | Enterprise Articles Microsoft

One can imagine many scenarios where Dynamics CRM either publishes data to BizTalk Server or queries BizTalk-exposed service endpoints. For instance, when a customer requests a refund for a defective product, the call center agent may record this request in Dynamics CRM. After the phone call is over, Dynamics CRM should send a message to a returns processing system which handles the crediting of a customer's account. In another scenario, BizTalk Server may be the host of a data aggregation service which queries three enterprise systems that store "customer" data and aggregates the responses. Dynamics CRM may want to execute that service when a call center agent views a customer record so that they get a fuller picture of that customer's interactions with the company.

In this article by Richard Seroter, author of Microsoft BizTalk 2010: Line of Business Systems Integration, we will see how Dynamics CRM sends data to BizTalk Server.

Common AsyncTask issues

by Steve Liles | December 2013 | Open Source

In this article by Steve Liles, the author of Asynchronous Android, we will take a look at AsyncTask which was introduced in Android at API level 3, Cupcake, with the express purpose of helping developers to avoid blocking the main thread. The Async part of the name of this class comes from the word asynchronous, which literally means not occurring at the same time. AsyncTask is an abstract class, and as such, must be subclassed for use. At the minimum, our subclass must provide an implementation for the abstract doInBackground method, which defines the work that we want to get done off the main thread.

As with any powerful programming abstraction, AsyncTask is not entirely free from issues and compromises.

Collaborative Work with SVN and Git

by Thomas Deuling | March 2013 | Beginner's Guides Open Source

Collaborative work is an important topic at present. Many large projects are now being developed in a collaborative way. But this was not always easy for the developer. When many developers are working together on large projects, each developer must have a well-known area of work, and each developer must make sure that he doesn't interfere with the work of the other developers.

Without tools such as SVN or Git, large projects like jQuery or Linux Mint could not be possible. The developers of all these projects are distributed all over the world and they often work in different time zones and have different ways of working, but in the end all the parts are merged into one great project in SVN or Git.

So, SVN and Git are a great enrichment for all developers and essential for the fast progress of large web projects.

In this article by Thomas Deuling the author of Aptana Studio Beginner's Guide, we will take a look at how easy it is to work with SVN and Git in Aptana Studio.

ColdFusion AJAX Programming

by John Farrar | April 2009 | AJAX Web Development

This article deals with AJAX programming in ColdFusion. ColdFusion acts a great platform not just because of its code features, but because of its characteristics as to how the code interacts with other features. ColdFusion is a language with depth and power. Yet, as we developers know, it seems real power always requires a bit of custom code. In this article by John Farrar, we will have a look at the following topics:

  • Binding
  • Proxy connections
  • JSON features
  • Spry data integration
  • Debugging

ColdFusion 9: Power CFCs and Web Forms

by John Farrar | August 2010 | Web Development

In this article by John Farrar, author of ColdFusion 9 Developer Tutorial, we will learn to move forward from making our code work to making it interesting to write and reuse. We could call this a "power CFC". Power is doing away with the old practice of copying and pasting code again and again with some minor edits in the pasted code. Here, we will learn to reuse the CFC code to make it much simpler. CFCs are the object-packaging method used in ColdFusion. Database interaction is quite universally wrapped in CFCs. We will look at database interaction as our primary example of power CFCs in the context of working with "web forms". If you are new to development, then these concepts will make it easy for you. Here is an overview of what this article contains:

  • The practice of protecting access to CFC methods
  • The working of web forms
  • Managing multiple products through common forms for listing, editing, and adding data
  • Improving the page flow, also known as work flow
  • Returning messages to the user to know things are working
  • Learning the power of inheritance
  • Simplifying by passing array collections, rather than manual line-by-line passing of the variable values
