Web Service Software Factory Guidance

2008-10-11T21:54:00Z

A set of integrated tools that helps quickly builds web services based on a well known design pattern and architecture

it gives you the power to :
1- Build messages and service interfaces.
2- defining fault contracts.
3- Building the host application.
4- Build test client application.
and more....

It didn't take me lot of time to get with the service factory guidance; it provides you with sequential recipes that allow you to quickly start your web service.

I found that it is really interesting to use this tool as it really removes a lot of the overhead while creating a service

Tips for ASP.NET Performance

2008-03-21T22:05:00Z

Performance , performance and performance the hard formula for any enterprise application that we will be expecting a very huge number of requests from its users/visitors, having a performed application is very hard to have but it is not impossible, it requires you to be able to identify your bottlenecks being able to analyze your application and to use a Tool that helps you in the application performance analysis , here am providing you with Tips that will help you in reaching a reasonable performed application, please note that if you have any question regarding the tips please feel free to add your comment and I’ll be there to provide you with support and resources.

Tip 1:

Put first things first, what I mean here is to be able to identify the system’s bottleneck, where you are expecting to have a highly loaded functionalities, what are the integration points of those functionalities, are we connecting to a 3rd party web service which will decrease the network performance, are we having a poor hardware configuration for the SQL server which will lead in a further stage in a poorly processing power “CPU”.

Tip 2:

Why you don’t utilize the web load test and the web test scenarios Tool provided by the Visual Studio Team system, it is really a very handy tool when you need to examine your web application under stress, using the Load Test will allow you to check where is your performance problem resides, is it on the front end server, is it because of a network latency, is it because of your SQL server.

Tip 3:

Trying as much as possible to decrease the size of your developed pages allows for having a potential performed web application, this affects the network bandwidth a lot. By trying to avoid large view state, large embedded HTML you will get a minimal page size as possible.

Tip 4:

Caching…Caching…and Caching please try to use it, you have the a real weapon that works fine to improve your application’s performance really fast, try to put a caching plan for your application to know which parts of your application’s data will be cached, you also have the ability to cache the output HTML to avoid the rendering process each time a user requests your page.
To be continued….

Enjoy :)

MOSS and ASP.NET AJAX Network Calls

2008-03-14T21:36:00Z

As we know ASP.NET AJAX allows us to invoke web services through what we call it AJAX network calls, when we add a reference to a web service to the page's Script Manager we instruct it to generate a proxy client for that web service in a JS format ,

for certain reason this is always a problem in MOSS, if you are having the same problem all you have to do as a work around is to generate a the proxy client manually and save it as part of the MOSS resources as a JS file and start linking this file in your pages instead of the service reference tag in the Script Manager

this works just fine but it has couple of problems such as you will need to update this proxy manually each time you change the web service signatures

Using .NET C# LDAP Library

2008-02-18T20:16:00Z

Well i were navigating for some sort of a wrapper for an openLDAP directory until i found one that really works

".NET C# LDAP library provides easy access to any LDAP compliant directory from managed code. The library enables the developers to write LDAP enabled applications that access, manage, and update information stored in Novell eDirectory or other LDAP-aware directories. We assume that the user of the library is familiar with general understanding of LDAP before using the class provided in the library. This document provides an overview of the .NET C# LDAP library and programming code examples." by Sunil Kumar

amazing component really, and i tested and it's working like a charm , if you would like to download it here is the URL

Creating Efficient ASP.NET AJAX Applications

2007-08-25T13:08:00Z

ASP.NET AJAX UpdatePanel control introduced a new mechanism to avoid page flickers during postbacks , while we did gained from this approach we should carefully use the UpdatePanel control.

ASP.NET AJAX was not only introduced to give us a user friendly application but also to provide us with an efficient and performed applications and to minimize the amount of data sent on the wire during postbacks, here am just giving couple of tips to follow while using the UpdatePanel control

Am summarizing here couple of tips you should follow

1- Whenever using multiple UpdatePanel controls in your page consider setting the UpdateMode property to conditional to minimize the amount of data sent over the wire.

2- Whenever using the UpdatePanel control try to nest only those controls that will be updated from the server against the pages’ events

3- Try to avoid using the UpdatePanel control, the only drawback of using this will be including some javascript code, the effort you will introduce in doing so will increase your application's performance.

Consider reading the following articles

MultiView control in ASP.NET 2.0

2007-03-31T13:44:00Z

During the past days of ASP.NET 1.1 we used to use multi panels whenever we needed to separate our controls in a specific block and to show/hide the panel whenever needed
now ASP.NET 2.0 provide us with the Multiview control it is used for the same concept with less overhead

here is an example

<asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0">
<asp:View ID="view1" runat="server" >
</asp:View>
<asp:View ID="view2" runat="server"></asp:View>
</asp:MultiView>

and then you can use the following to activate a specific view

MultiView1.SetActiveView(view2);

Series: AJAX ABC - Part 1

2007-03-14T07:53:00Z

I decided to start a new series to present AJAX from another point of view which is providing definitions, guidelines of the AJAX components,

First we will start this entry with what is AJAX?
AJAX is shorthand of "Asynchronous JavaScript and xml" from this definition we start to know that AJAX is not a new technology but set of already known technologies and tools that provide us with a new web user experience.

from the above we could start to understand :-

1- AJAX is a technique not a technology.
2- You should know about JavaScript, XML, CSS and also browser compatibility issues.

also to note here AJAX is not a new technique that we knew about today, it was already existing over the internet but we didn't give any focus on it.

somebody would start to say will AJAX going to replace Flash?, no it will not the one that will do so is WPF\E which already has full integration to ASP.NET AJAX

anyway this is enough for now see you in the coming entry....

next entry will be focusing on the challenges we will face when implementing AJAX over the internet..
Enjoy ;)

SqlBulkCopy – one major feature in the ADO.NET 2.0

2007-02-09T21:25:00Z

There was in the past lots of approaches to transfer data from one table to another those methods deferred in its complexity or in the performance impact behind applying it,
We face this scenario everyday in our real life projects and even in our small code snippets that support us in the data migration process while project deployments and so on…

Taking the above scenarios in our minds the ADO.NET 2.0 introduced the SqlBulkCopy class which work as a schema mapping between two data sources and starts transferring data from a source data table to another.

This operation takes the following steps:-

1- We define the data source and the targeted destination

2- Then we start mapping the data attributes – columns – between the source and the destination tables.

3- After that we start configuring the BatchSize – the number of rows to be copy in each attempt to copy- and the BulkCopyTimeOut.

4- We also have a SqlRowsCopied event which get fired whenever the number we define in the NotifyAfter property got reached.

Let’s go to the enjoyable part which is CODE J

protected void MoveData(DataSet dsSource)

{

using (SqlConnection connDest = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString()))

{

using (SqlBulkCopy bulkCopyobj = new SqlBulkCopy(connDest))

{

//Start mapping columns

bulkCopyobj.ColumnMappings.Add("SourceID", "DestID");

//configure the SqlBulkCopy Properties

bulkCopyobj.BatchSize = 90;

bulkCopyobj.BulkCopyTimeout = 15;

bulkCopyobj.NotifyAfter = 250;

bulkCopyobj.DestinationTableName = "DestinationTable";

bulkCopyobj.SqlRowsCopied += new SqlRowsCopiedEventHandler(bulkCopyobj_SqlRowsCopied);

//start moving data

bulkCopyobj.WriteToServer(dsSource.Tables[0]);

//close the bulk copy operation

bulkCopyobj.Close();

}

void bulkCopyobj_SqlRowsCopied(object sender, SqlRowsCopiedEventArgs e)

{

Console.Write(string.Format("{0} Rows copied....",e.RowsCopied.ToString()) );

}

protected DataSet GetData()

{

using (SqlConnection connSource = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionSource"].ToString()))

{

SqlDataAdapter da = new SqlDataAdapter("GetDataFromSource", connSource);

DataSet ds = new DataSet();

da.SelectCommand.CommandType = CommandType.StoredProcedure;

da.Fill(ds);

return ds;

}
