This tiny demo source code will give you a hint about how to query data stored on your server via XMLDB Engine Lite (XMLDBelt), create new files, insert data into existed, update data, delete and etc.

An article that briefly describes commonly used Design Patterns; Singleton, Factory Method, Adapter, Proxy, Decorator, Composite, Observer, MVC, Template and Strategy.

This article explains how to convert the database-driven query string containing links to search-engine friendly ones.

ASP.NET Forum Share the knowledge and get all the help you need to start developing secure ASP.NET Web applications and share your development issues.

This article provides some helpful tips in working with ASP.NET on Microsoft's Internet Information Services (IIS) web server, providing walkthrough descriptions and resolutions for common problems that the author has experienced.

If you are working in a mixed development environment you know that ASP "Classic" and ASP.NET cannot share session state information. I am offering the source code I used to this resolve this issue as well as discussing a couple of other possible resolutions.

Recently we had a Website that was redone from a large static site to a dynamically driven site in ASP.Net. The original site was heavily indexed by the major spiders on the Web, we did not want to lose the reference links in the engines and wanted to make sure the link clicked on would go to an appropriate paged in the site. In this article we cover how to create a document mapper so the old URL is redirected to the new related page within the new site.

In this article we will cover working with the system registry, both reading and writing values. In this example, we will cover creating a license registration for your application.

In this article we will cover exposing an existing ASP.Net application as a Web service. We will provide methods for creating the Web service, converting readers to data sets, and a client application for the new service.

Here we provide several methods for managing your Active Directory database via ASP.Net code. We'll cover querying user information using System.DirectoryServices, changing user accounts, and group management.

I've been working on a financial reporting project lately and came upon the idea of bringing our charts from ChartFX.NET to life. The idea being that we could dynamically review each pixel's color in the chart in order to generate an HTML image map on the fly. This would enable us to apply supporting documentation in the form of links or JavaScript functions to perform some sort of action when the user moves their mouse over the chart or clicks a section of it.

At my place of employment, I work a great deal with somewhat complex hierarchical data as part of our measurement and analysis software. Thus, recursion and I have become rather close friends over the last few years. While rewriting an old website, I needed to turn a set of four relational tables into a hierarchical data structure. The top level table held self-referencing relationships as well as child relationships to table 2. Tables 3 and 4 were your basic "run of the mill" child tables up through table2.

Recently, I had a requirement to put together a website that deals with taking somewhat elaborate financial surveys. While the questions and answers themselves are good candidates for being database driven, there were a large number of nuiances ranging from UI items, business rules, and calculations that just didn't fit into a database driven strategy. With this in mind, my initial strategy was to create version specific classes and reference them in version specific ASP.NET pages. Of course, this accomplished the initial requirement. However, whenever a new version needs to be implemented, I had to copy all of the ASP.NET pages and modify the references to the appropriate version specific class name. Refactoring provides a better alternative and here's how:

We will create a custom dropdown conrol using a datasource. This code provides us to fill a dropdrown list using a datasource. This code also displays us ASP.NET is easier than classical ASP to generate custom controls.

Mostly we want to change output results of our applications to another culture setting. In this code sniplet we will format current date time for our culture settings

The following source code displays count of all records in a database. We will use a data command to execute an SQL statement that will return with count of records. Source code written in Visual Basic.NET can easily modify to work in an application.

While working with file system, sometimes we must list all directories in a folder. This sample shows us how to list all directories in a folder. Source code written in Visual Basic.NET can easily modify to work in an application.

We will use RDN function to generate a random number. Our first example generates a random number between 1 ~ 10.

We can easily connect a database server within an assembly. After we compile this source code you can access your database provider. In tis source code I have used SQL Server.
