Ajax website build error : Could not load type 'System.Web.UI.Compatibility.CompareValidator' from assembly 'System.Web.Extensions'

Hey...

When i try to build solution for a Ajax based web site with Visual studio 2008 using the Framework 2.0, It gave the following error :

Could not load type 'System.Web.UI.Compatibility.CompareValidator' from assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

I was wondering what could be wrong! I tried placing system.web.Extensions in local bin folder. Tried placing in GAC again. There was no luck... when i goggled, found the following articles which was helpful. It seems the validators are removed in recent releases. The solution is to comment the following tags in web.config:

<tagMapping>

<tagMapping>

Resource articles as follows:

Forums.asp.net , Robin's Blog

Hope it helps

Merry X-Mas :) Wish you Happy New Year 2009 :)

Where is Chandrayaan now

Where is chandrayaan now…

It’s in the fourth orbit raising manoeuvre of Chandrayaan-1 spacecraft today (October 29, 2008). Chandrayaan-1 entered into a more elliptical orbit whose apogee (farthest point to Earth) lies at 267,000 km while the perigee (nearest point to Earth) lies at 465 km.Now Chandrayaan-1 spacecraft is more than half the way to moon. In this orbit, the spacecraft might take six days to go round the Earth once. And there is one more orbit raising manoeuvre is scheduled to send the spacecraft to the vicinity of the moon at a distance of about 384,000 km from the Earth.

Let’s hope for the best :)

Came to know that there is one more main part of Chandrayaan’s mission, its to explore helium-3 resources from moon. It seems moon has abundant resources of helium-3 from earlier studies; which could be used in Fusion reactors to produce power. Following is an animation to explain how the fusion occurs in DT helium reactor. One atom of deuterium and one atom of tritium combine to form a helium-4 atom and a neutron. Most of the energy released is in the form of the high-energy neutron.

Fusion of Deuterium with Tritium creating helium-4, freeing a neutron, and releasing 3.5 MeV of energy.

Update on 31st August 2009: Couple of days before ISRO lost contact with Chandrayaan. which is not a Good news but scientists say Chandrayaan has made almost 95% of its work so far... This sounds good & let wish all the best for the future endeavours of ISRO.

Chandrayaan mission count down

Mission Objectives:

* To launch and orbit a spacecraft in lunar polar orbit and conduct scientific studies.
* To carry out high resolution mapping of topographic features in 3D, distribution of various minerals and elemental chemical species including radioactive nuclides covering the entire lunar surface using a set of remote sensing payloads. The new set of data would help in unraveling mysteries about the origin and evolution of solar system in general and that of the moon in particular or on its composition and mineralogy.
* Realize the mission goal of harnessing the science payloads, lunar craft and the launch vehicle with suitable ground support system including DSN station, integration and testing, launching and achieving lunar orbit of ~100 km, in-orbit operation of experiments, communication/telecommand, telemetry data reception, quick look data and archival for scientific utilization by identified group of scientists.

Sample to Read & Write XML File through C#

Hi,

Here is the sample to read and write xml file through C# code. In order to explain the process in a simple fashion, I made use of a xml file called SomeName.xml (The contents of the xml file are shown below in Section #1). Through C# code i am reading the nodes and attribute values which any one would prefer to do in their application. Then to explain the process of writing a xml file into file system, I am making use of the values I read from input xml file. I create a XmlDocument Object in memory, create nodes and with the read values append them inside and write them to a new XML file in file system called WrittenFile.xml.

Section #1 has the content of input xml file, Section #2 contains the c# code to be placed in pageload event & section #3 has the content of generated output xml file.

Section #1:

Input XML file: ~\XML\SomeFolder\SomeName.xml

<?xml version="1.0" standalone="yes" ?>

<table>

</columns>

<rows>

</rows>

</table>

</report>

Section #2:

C# Code written in page load event:

protected void Page_Load(object sender, EventArgs e)

{

try

{

//Creating XmlDocument Class object:

XmlDocument oXmlDocument = new XmlDocument();

//Loading the XML file from File System:

oXmlDocument.Load(Server.MapPath("XML/SomeFolder/SomeName.xml"));

//1.To Read a Single Node

//Giving the Xpath of the Node: eg: //report/table/rows/row

//Assigning the returned XmlNoded from SelectSingleNode Method:

XmlNode oXmlElementCampaignName = oXmlDocument.DocumentElement.SelectSingleNode("//report/table/rows/row");

//2.To Read Collection of Nodes

//Giving the Xpath to method SelectNodes eg: SelectNodes("//report/table/rows/row");

//Assigning the returned XmlNoded from SelectSingleNode Method:

XmlNodeList oXmlNodeList = oXmlDocument.DocumentElement.SelectNodes("//report/table/rows/row");

// Create a XmlDocument object to write a file:

XmlDocument xmlDocument = new XmlDocument();

// Create a XmlElement which represents an Element : Root Element

XmlElement Items = xmlDocument.CreateElement("Items");

//Iterate through every nodes in oXmlNodeList which is a collection of Nodes

foreach (XmlNode objNode in oXmlNodeList)

{

// Create a XmlElement which represents an Element : Node

XmlElement Item = xmlDocument.CreateElement("Item");

// Create Child Node XmlElement1

XmlElement xmlelement1 = xmlDocument.CreateElement("XmlElement1");

// Sets value for Child Node

XmlText xmlelement1_text = xmlDocument.CreateTextNode(objNode.Attributes["Attribute1"].

Value.ToString());

// Placed inside Child Node

xmlelement1.AppendChild(xmlelement1_text);

XmlElement xmlelement2 = xmlDocument.CreateElement("XmlElement2");

XmlText xmlelement2_text = xmlDocument.CreateTextNode(objNode.Attributes["Attribute2"].

Value.ToString());

xmlelement2.AppendChild(xmlelement2_text);

// Placing under Node

Item.AppendChild(xmlelement1);

// Placing under Node

Item.AppendChild(xmlelement2);

// Placing under Root

Items.AppendChild(Item);

}

// Placing under XML document

xmlDocument.AppendChild(Items);

// Writing the XML file into file system

xmlDocument.Save(Server.MapPath("XML/SomeFolder/WrittenFile.xml"));

}

catch (Exception ex)

{

//Exception block here

}

Section #3:

Output XML file: ~\XML\SomeFolder\WrittenFile.xml

<Items>

<Item>

</Item>

<Item>

</Item>

<Item>

</Item>

<Item>

</Item>

<Item>

</Item>

</Items>

Hope this should be helpful for people who are looking to samples to read or write xml file.
