Con ASP podemos crear Intranets que automaticen los procesos de la empresa. Este artículo se sale un poco de la temática del Taller de ASP , pero creo que también puede dar ideas a los lectores sobre qué se puede hacer con ASP en la práctica en el mundo de la empresa. Hace unos días, un medico de aquí de la zona donde vivo, me dijo: Necesito que me hagas un programa para el hospital , te animas? El reto me sonó interesante y al enterarme de los detalles, vi que era una encuesta que querían cargar a la PC, para luego realizar algunas estadísticas con la información recabada. Yo le dije que me animaba, y analizando el proyecto me encontré con una encuesta de 170 opciones y campos.
Introduction This program reads the MySql informational_schema database and, after the user has selected the target database, creates a C# source file containing typed dataset and TableAdapter classes for the contained tables. The code produced is similar to that produced for SQL Databases, but it does not include XML Serialization Designer code Before the code is generated, the program displays the names of the base identifiers it is going to use, giving the user the chance to change them (MySql seems to be case insensitive and table names such as 'CustomerOrders' seem to be stored as 'customerorders' ).

Table of Contents Introduction and Scope of the Article Very often we come across a scenario where we need to execute same Insert or update commands with different values multiple times in one go. Say for example, show multiple records in updatable grid/tablular format allowing user to update them and then update them in database. Their are multiple ways to handle it and simplest being execute each DML command one after the other.
Introduction Even before .NET, when ADO was still an ActiveX API, connection strings have always been a point of confusion for a lot of developers. This mostly stems from the fact that a connection string is structured information with a specific format that developers have always been expected to be able to produce from memory or have to look up in documentation.
by Joe Mayo, 8/9/04, updated 1/12/09 This lesson describes the SqlConnection object and how to connect to a data base. Here are the objectives of this lesson: Know what connection objects are used for. Learn how to instantiate a SqlConnection object. Understand how the SqlConnection object is used in applications.
Now I will discuss about, how we can transfer a large file (file size in GB) using Microsoft dot net socket programming using C# (C sharp) language. This code has written in Visual Studio 2005 (dot net 2). Basic Knowledge To cover this article you need to read my few articles, these are –
Navigation applications are an attractive feature of Windows Presentation Foundation that allow you to create task-focused user interfaces in a manner that is very difficult to achieve using Windows Forms. In this article, I'll discuss some of the benefits the navigation application model provides, then describe the features in WPF that make building them possible. I hope to dispel a few myths and concerns about them in the process. Oct 2 2009
Ten years ago (around the year 2001) I wrote a simple x86 protected-mode OS just to find out how operating systems work. That was really great fun and I learned very much about OS concepts and paradigms (and also a lot of stuff about computer hardware, programming, software architecture, data structures etc.). Ever since the gathered experience and knowledge by building my own operating system has been extremely valuable. I began by reading Andrew Tanenbaum 's book "Operating Systems: Design and Implementation" during which I studied a lot of Minix source code. Later I also read his other books about modern operating systems and structured computer organization .

Programmer's Heaven C# School Book The Programmer's Heaven C# School book covers the .NET framework and the C# language. Starting with the basics of the language, it goes on to cover object oriented programming techniques and a wide range of C# languages features including interfaces, exceptions and delegates. Later chapters cover practical topics including database access with ADO.NET, building Windows forms applications, multi-threading and asynchronous I/O.
Introduction After having developed a number of applications using LINQ to SQL technologies, I have finally decided to take a close look at LINQ to Entities. We know that Microsoft stopped developing LINQ to SQL, though they keep supporting it.
Good to know, I will give a more serious look to this pearl or I may bet for HTML5. by Oct 24
In my humble opinion, Linq is easily the greatest thing .Net has come out with in the past few years, and along with it, Linq-to-SQL (L2S) was a godsend. Being quick to hop on the L2S bandwagon, I quickly became a huge fan of the framework, it is amazing easy and useful. That being as it is, I was quite disappointed when I heard that Linq-to-SQL was no longer going to be advanced at all . Now, it is surely not dead, it is still very usable and effective at what it does, but I like to stay with frameworks that will be actively advanced and fbug-fixed. So I decided to make the jump to Linq-to-Entities (L2E), and it was suprisingly simple.
