Hi,

Yesterday I was sitting idle and trying to write some dummy windows application. Suddenly I saw that my application is using a lot of CPU resource.

But what if I wanted to know the CPU Usage of an application without using the task manager. Well what if you wanted to show the CPU usage of the current Application to the user. Well I searched a bit and got the answer. So I thought I would share the code with all.

Here is the code for showing the CPU Usage by all the currently running application.
foreach (Process process in Process.GetProcesses())

            {

                using (PerformanceCounter pcProc = new PerformanceCounter("Process", "% Processor Time",

Hi

In the string class we have 2 methods to compare the string. I see most of the developers get confused between the 2. Both string.Compare and string.Equals methods are used for string comparison but they significant difference between them. The use of wrong method can lead to globalization and security issues.

String.Equals perform an ordinal comparison while string.Compare performs a culture sensitive comparison.

string.Compare method also has overload to be given the culture. By default it uses the current culture.

The comparison uses the culture parameter to obtain culture-specific information such as casing rules and the alphabetic order of individual characters. For example, a culture could specify that certain combinations of characters be treated as a single character, or uppercase and lowercase characters be compared in a particular way, or that the sorting order of a character depends on the characters that

Hi,

When we are working on an asp.net Application we have to work with various type of Path. These paths are present in the Request Object. Each path has a different meaning and way for representation. Here is a list of different kind of paths used in Asp.net

Application Path – Will return the root path of the application. This is used to get the application path. This can be found in Request Object. By the default the

CurrentExecutionFilePath – used to get the virtual path of the current request. The difference from the FilePath property is that if there is a redirection of the request in the server code (Server.Transfer) then this will return the correct value. For example it might return the value //Vikramlakhotia.com//MyAdm//LogFeed.aspx

FilePath – will provide the Virtual Path of the current request. (See the difference with CurrentExecutionFilePath above.)

Path – Returns the

Hi,

A web site Application can have multiple files of multiple file type. Many of these are managed by Asp.Net and many by IIS itself. File types that are managed by the Asp.Net are mapped to AspNet_isapi.dll in IIS. The file types that are not mapped to AspNet_isapi.dll are not managed by asp.net but by IIS only.

Here is a list of all the file types that are managed by Asp.Net.

.asax – The common most example is the Global.asax file. This normally contains code that is derived from HttpApplication class. The file contains application level event that are raised by application like Application start, application end etc. The file has to be kept in the root folder of the application.

.ascx – This file type is used to create web user control. The file can reside in either root folder on in a sub-directory.

.ashx – The file type is used to create generic handler by implementing the IHttpHandler interface.
