Sandarenu's Blog

For last 6 months I was working as an intern at Navantis IT (Pvt.) Rajagiriya, Sri Lanka. My internship ended last Thursday (22nd Feb). It was very exciting and challenging time period. It is at Navantis that I learned what is actually being a software developer means. At the university we learn lot of theory; in last 6 month I learned how those theories are actually used in the industry. I learned a lot about .Net, ASP web application development and MSSQL 2005 during my internship.
When I first came here I had considerable knowledge about .Net and ASP, but I was mainly using the nice GUI of VS2005 to do all the designs. But the project I was put in to at Navantis required to all the web controls as Custom server controls. We have to cut code for every thing, No drag and drops... At the beginning it was difficult but after creating few custom controls it became much easier. Because of that I learned a lot about C# and .Net controls.
We had a excellent team at Navantis. Everybody was very friendly and helpful. I have to thank everyone at Navantis for all support given. Our next semester (Level3 Semester2) is gong to be staring in mid April, that’s two more months. Till then I'm doing part time at Navantis, 3 days per week. I'm planning to spend other time on Patrick’s Project. And I have to prepare a report about our internship as well.
So I guess there won't be any spare time to relax.

ViewState is one of the 3 way that used by ASP2.0 to retain state information about the web page. ViewState allows the state of objects (serializable) to be stored in a hidden field on the page. It is transported to the client and back to the server, and is not stored on the server or any other external source. I’m not going to go deep in to what is ViewState or how to use it. You can find more about ViewState here>>.

Since ViewState is kept in the webpage itself, it can become a performance bottleneck. If the ViewState is too large then the roundtrip delay for postback can increase significantly, especially if the user is having slow internet link. So it would be wonderful if we can find out the size of the ViewState during the testing phase of the application. So we can get relevant actions to improve the performance.

To do that create a class (I named it as MainPageBase) class that all the other pages in the application need to inherit. The code for the class is as shown below.

public class EmsBasePage : System.Web.UI.Page
{
/// <summary>
/// Get the page name of the current page.
/// </summary>
/// <returns></returns>
private string GetCurrentPageName()
{
string path = System.Web.HttpContext.Current.Request.Url.AbsolutePath;
if (!String.IsNullOrEmpty(path))
{
System.IO.FileInfo oInfo = new System.IO.FileInfo(path);
string name = oInfo.Name;
return name;
}
else
{
return "";
}
}

protected override void SavePageStateToPersistenceMedium(object state)
{
int viewStateSize = 0;
base.SavePageStateToPersistenceMedium(state);
LosFormatter format = new LosFormatter();
StringWriter writer = new StringWriter();
format.Serialize(writer, state);
viewStateSize = writer.ToString().Length;
string pageName = GetCurrentPageName();
HttpContext.Current.Trace.Warn(pageName + ": The ViewState Size is:", viewStateSize.ToString());
}
}

It writes the size of the ViewState to the Trace. To view the Trace you have to enable it first. To do that adds following line of code within the section in the web.config file.

<trace enabled="true" pageOutput="false" requestLimit="40" localOnly="false"/>

That’s all. Compile the code and do the testing of your application. Finally to view the results of what we did open the Trace viewer(Trace.axd page). For example http://yourApplicationroot/Trace.axd.

Have you ever wanted to view every detail about your computer using a single program? Then SIW (System Information for Windows) is the solution you are looking for. Using SIW you can view lot of information about your computer, which previously needed to run different tools included in Windows.

You'll get information about the operating system and the installed patches, the software licenses, drivers, Windows services, codecs, open files, saved passwords, hardware information (motherboard, CPU, memory, video card, ports) and some useful tools (like Eureka, that reveals passwords from some applications).

Cool thing about SIW is that it doesn't require setup, so you can copy it to your USB drive and use it where ever you need. You can export all the data in different formats (CSV, HTML, TXT or XML), and use the program from the command-line.
You can run SIW on almost all windows platforms (Microsoft Windows 98/Me/NT4/2000/XP/Server 2003/Media Center/Tablet PC/Windows 2003 Server R2/Windows Server 2003 x64/Windows XP x64/Windows Vista).

• "...one of the strongest motives that lead men to art and science is escape from everyday life with its painful crudity and hopeless dreariness, from the fetters of one's own ever-shifting desires.

• "He who joyfully marches to music rank and file, has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would surely suffice. This disgrace to civilization should be done away with at once.

It is my conviction that killing under the cloak of war is nothing but an act of murder."
• "A human being is a part of a whole, called by us _universe_, a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest... a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty."
