Hi, every body,

My name is Landry Defo Kuate, i'm a software architect.

All this year, my boss have the great idea certified our business whith the CMMI certification. to achieve this challenge, i mission was to develop some components that we can reuse in our software developement.

In this series of articles, i want to speack of some of those components. I will base my talk on Microsoft preconise architecture for software developpement.

So stay in touch on this blog for more information on who components can help pass the first and difficult level of CMMI certification.

Nice things of this week

Hi all,

I have been spending half of the preceeding week coding a little usefull tool : let's say a metacode tool. How many time have you been written the same style business objects, having only accessors (getter and setter) and DAO (Data Acces Objects) functionalities changed. When you have done it twice, you are bored and you don't want to repeat it.

That's why I have stopped all personnals stufs last saturday and have written a Developer experience librarie. Let me give more details about it.

Okay first of all I have set up a basic data acces class with all necessary code to get in to my Sql server database. The tool enable me then to generate automaticcaly the objects acces and manipulations classes with respect to some little conventions. See the sample right there

DevelopersExperienceLibraries.ObjectGenerator myGenerator
= new DevelopersExperienceLibraries.ObjectGenerator();
System.Collections.ArrayList myTypes = new ArrayList();
DevelopersExperienceLibraries.TypeInformation tiIdModule = new DevelopersExperienceLibraries.TypeInformation("_idModule","int",string.Empty,true,true);
DevelopersExperienceLibraries.TypeInformation tiCodeModule = new DevelopersExperienceLibraries.TypeInformation("_codeModule","string","string.Empty",true,true);
DevelopersExperienceLibraries.TypeInformation tiIntitule = new DevelopersExperienceLibraries.TypeInformation("_intitule","string","string.Empty",true,true);
DevelopersExperienceLibraries.TypeInformation tiDureeModule = new DevelopersExperienceLibraries.TypeInformation("_dureeModule","int",string.Empty,true,true);

myGenerator.TypeList = myTypes;

myGenerator.ObjectFileName = "D:\\Elsam\\Internals\\GeneratedClasses\\Module.cs";
myGenerator.ObjectName = "Module";
myGenerator.ObjectNameSpace = "GBusinessDataAcces";

DevelopersExperienceLibraries.DAOGenerator myDAOGenerator = new DevelopersExperienceLibraries.DAOGenerator();
myDAOGenerator.GeneratorObject = myGenerator;

myDAOGenerator.DataAccesConnectionString = "server=ALAINLOMPO\\\\MYSQLSERVER;DataBase
myDAOGenerator.IdName = "IdModule";

I hope the rendering will be nice.
It has been very usefull for me this week, enabling me to generate 18 acces and DAO classes in 4 hours. And everything was going right

Orchestrating web services with Biztalk Server

BizTalk Server is the cornerstone product in Microsoft's business process and integration strategy. It is through BizTalk that Microsoft is providing the tools to enable developers to integrate applications, businesses, and EDI, and also orchestrate and coordinate information systems with the business users who drive those systems and their processes. In addition, BizTalk provides a developer experience integrated with Visual Studio, making BizTalk applications easier and more intuitive to develop, and integrating easily with existing Microsoft systems and tools that a business may already use. BizTalk currently has the distinction of being the only server product at Microsoft built primarily on the .NET Framework. The upcoming release of BizTalk Server 2006 extends BizTalk Server 2004 to provide new features for developers building orchestrations and integrating applications and simplifies creating orchestrations that consume or create Web services.
BizTalk Server 2006 has several key enhancements related to Web services. These include the BAM Query Web service, the ability to use Web services outside of orchestrations for messaging scenarios, and support for SOAP arrays. This article explores what you need to do to set up a basic orchestration scenario in BizTalk Server 2006 that consumes a Web service. Then you'll look at how you might process the Web service results and extend the orchestration for other uses.
What You Need
To view the sample code you need Visual Studio 2005 and BizTalk Server 2006 Beta 1 or the BizTalk Server 2006 November CTP. For more information, see the BizTalk Server 2006 beta installation guide available from Microsoft Downloads.Setting Up a Web ServiceTo get started, you'll need to set up a .NET Web service that returns an array of results to a BizTalk orchestration. To do that, you'll start with Visual Studio 2005 and create a new ASP.NET Web service project. I'll show you how to add a Web service method to support the orchestration, but that will be sufficient for you to visualize how you could extend the service as needed.In Visual Studio 2005, selecting the default Web service project type from the New Project wizard creates a .cs file with a class derived from System.Web.Services.WebService. Attributes that assign a Web service namespace and establish bindings are included, but you'll need to add your own method (or replace the default HelloWorld method) with your code.A Sample Method to Return a SOAP ArrayCreating a method to return a SOAP array is pretty straightforward. You can use the sample code below, which creates an array of integers, populates the array in a for loop, and returns the array. using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "")]
[WebServiceBinding(ConformsTo =
public class Service : System.Web.Services.WebService
public Service () {


public int[] GetArray()
int[] a = new int[10];
for (int i = 0; i < 10; i++)
a[i] = i * 5;
return a;


Testing the Sample Service
After creating the method, you should test and deploy the service for use in the BizTalk application later. When you use HTTP POST to invoke the service from Internet Explorer, you should get the following XML output in your browser:


When you have the Web service up and running, the next task is to incorporate it into your BizTalk application

Yeah we got it

After many attemps to rise the interest of our customer for the fax solution we proposed, we finaly got them into a bullet.

And of course Microsoft .Net had something to do with it. Our customer a great bank enterprise was hesitating between the world leader fax server solution and an open one despite of the fact that we had a lower price than the concurrent.

The customer needed to have the fax solution performing very specifical tasks: that is things that were not offered as standard functionalities.

So we try... catch it with Microsoft .Net. Taken the WeFly247 airplane, .Net come to rescue and rescue :) Yeah we got it
