Log Parser usage
Log parser is a free tool from Microsoft where developers and support technicians can use to parse the IIS logs, Event Logs and Active Directory logs. This tool helps the developers to find the root cause for the site related issues. This post explains common commands that we use to look for specific information in IIS logs.
The tool can be downloaded from here
The default location for IIS logs is %windir%\System32\LogFiles\W3SVC<SiteID>.

Under the tabs you had the forward, back buttons and Reloadbutton, bookmark button and address bar. Using the address bar you can navigate to site and can use it for searching the Internet.
2. You can find the following option by clicking the control the current page button
With New incognito window feature is like IE 8 private browsing feature where people can do private browsing and Google can not view what the user browsing.
3. You can see the source of the of the page from the developer and you can debug the java script through task manager you can view the CPU usage,memory and network bandwidth of the sites that you are browsing.
4. You can find the following options under customize button.
When you click on the History you can see all the sites you browsed and you can even search the history.

Introduction
Securing a Web service is possible using WSE (Web Services Enhancements) for .NET. We can define the security requirements for both incoming and outgoing SOAP Messages this we can call it is a policy.
We can define the policy in two ways
1. Using WSE Settings 3.0 Tool
2. Adding the policy element to the XML file
Alternatively we can define the policy file either in development or deployment environment. It is more easy for an administrator to define a policy for an application when it is deployed using policy file.

No commentsExtension Methods Feature in C# 3.0
It is one of the new feature introduced in C# 3.0 “As the name implies, extension methods extend existing .NET types with new methods.”
Here i am going to extend the String type to write an extension method.
Example Adding a IsValidEmailAddress method onto an instance of string class:
namespace Extensions
{
class TestProgram
{
static void Main(string[] args)
{
string strEmployeeEmail = “kalyan@techbubbles.com”;
if (strEmployeeEmail.IsValidEmail() ) // IsValidEmail is extension method
{
//Do something
}
}
}
public static class Extensions
{
public static bool
IsValidEmail( this string s )
{
// Do something
return;
}
}// this key word in front of the parameter makes this an extension method
}
The extension methods should be static methods in a static class with in same namespace as shown above. The this keyword in front of the parameter makes an extension method.

If you want to run your existing ASP.NET 1.1 websites under .NET Framework v1.1 please read this post Configuring .NET Framework 1.1 on windows vista and follow the below steps.
1. Open IIS 7 by going through Control Panel/Administrative Tools and please select the ISAPI and CGI Restrictions option from IIS section.
2. Allow the ASP.NET 1.1 in the ISAPI/CGI restrictions.
3. Make sure that your application pool should run in a 32-bit mode + v1.1 + classic mode.
Below are the commands using appcmd.exe tool which would do this.
appcmd.exe can be found under C:\Windows\System32\inetsrv.
- appcmd apppool set /apppool.name:”ASP.NET 1.1” /enable32BitAppOnWin64:true
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /managedRuntimeVersion="v1.1"
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /managedPipelineMode:"Classic"
- appcmd apppool set /apppool.name:"ASP.NET 1.1" /autoStart:true (optional)
4. Alternatively you can also use this option to run your application pool under .NET FW v1.1
