Tracking events based on date is one of the most common requirements in our daily lives. Event calendar is one of the most popular solution where user can easily track his/her or agents or subordinates daily most important activies. Most of the free components probably can't implement your demand. In asp.net you can use calendar control to fullfill custom demands. But i am trying to develop a calendar without using calendar control. To do this i choose DataList because here i can define column no & repeat direction which make me interested. I want to produce my output like below:

This article will explores about .NET remoting. .NET remoting is a technology that allows you to invoke or accessing objects on remote server. For those who are familiar with Java technology, it is called RMI (Remote Method Invocation) in java world. .NET remoting supports accessing your objects by using HTTP,TCP and IPC channels. Similar with Web Services, .NET remoting also support calling your objects via HTTP protocol. However Web Services provide platform independence and you also get loose coupling between your client server objects which means that easier to deal with versioning issues. Unlike Web Services, .NET remoting requires both of your client and server objects running on the same .NET Framework version. and it has a tight coupling between client and server because the same object types are shared.

Explains how to use threads to enable multitasking in ASP.NET applications. Performance and responsiveness are most the important key issues in the success of your web application. Sometimes you need to perform a long time task, that uses intensive CPU operations. A common solution to this problem is the use of multithreading.

Datasets store a copy of data from the database tables. However, Datasets can not directly retrieve data from Databases. DataAdapters are used as a link between them. This tutorial explains how to manipulate data in database using DataSet and DataAdapter objects.

The ASP.NET 2.0 Wizard control simplifies many of the tasks associated with building a web application. In this tutorial we will look at the basics of the Wizard Control by creating a simple data collection form and then advance to simulate an online test wizard that will be generated dynamically.

ASP.NET 2.0 Tutorial : Code Directory - In this tutorial you will having a deeper look at the Code Directory, the Code Beside Model and the evolution of the Code Behind model, learn about Partial Classes, Sharing Source components, Creating a Component, you will learn how to create a Application_Code folder, to create a component in the Application_Code folder and use a component.

VB.NET 2005 Tutorials: Adding Controls - In this tutorial let's discuss about Adding Controls to a Windows Form, Adding Controls using Windows Forms Designer, Adding Controls Dynamically and Setting properties of Controls. Sample source codes used in this tutorial are included. Forms are containers for control objects. All controls have properties, methods and events that can be used to customize their functionality.

In this article, I would like to explain about Error Handling in ASP.NET. How to handle the error in ASP.NET 2.0 when an error happens in your website, how to handle unhandled error, tips and tricks for better error handling and also I would give some sample code on how to do Error notifications to you as website owner if there is an error happen in your site.

For better error logging, you can actually store all the details in your database,so that you can have the history and easier for you to manage code error on your site.

Random number generation is a common programming endeavor, but many developers are unaware of the true nature of the random numbers generated by a system. In this article I would explain about how to generating a random numbers and how to use them in your .NET applications Generating random numbers is often a hot topic for programmers. The reason is that seemingly random numbers are most often not genuinely random. This is due to the deterministic algorithm utilized by a platform like .NET. Deterministic systems leave nothing to chance; they're lawful out of necessity; and they conform to the ideal of a machine in which wear and tear and mechanical failures are absent. Modern computers are conceived as deterministic machines. The Random class The .NET Framework provides the Random class, which allows you to generate a number or a series of numbers to be used accordingly. You may be wondering why .NET bothers to include the Random class.

In this article we will generate a random serial code for our applications. The script will generate a similiar serial code to use in a real application.

ASP.NET UserControl is the new way of encapsulate all your code reuse in your web applications. Old way of doing this would be via SSI includes which can be very messy and very hard to maintain if your site grow. ASP.NET UserControl is infact the simplest form of ASP.NET control encapsulation. Because they are the simplest, they are also the easiest to create and use. Essentially user control is a grouping of existing server controls into a single container control. This enables you to group all your reusable part of webpage into UserControl. The basic example would be Login Controls, News Controls, Header Controls and etc.

Implementing help for ASP.NET Applications and for .NET Windows Forms Applications have many similarities that will be highlighted in this tutorial and the reader will be thought how to implement it in both.
