    In this post we will look at the data structures and the necessary interfaces to develop connectors for any database to add to the DBTextFinder application, a tool for finding text in registers, stored procedures and views. You can also download sample code, developed with Microsoft Visual Studio 2013 with connectors for SQL Server, Oracle 12c and MySQL.

    In many applications it is necessary to generate random numbers. To do so, the .NET framework provides the Random class, which can generate uniformly distributed pseudo-random values, which means that all numbers are equally likely to appear in the result. But in some cases we need to generate random values that follow other different types of distribution. In this article we will see how to generate random numbers that follow a normal distribution, with a system that can be extended to any other type of distribution.

    In the previous article in this series, I did a summary of the basic components of DirectShow: filters, filter graphs and pins to connect the elements together, and how we can identify them using the GraphEdit tool of the SDK. In this article I will show how to build a "simple" application to capture and playback video using the interfaces provided in DirectShow, a subset of the COM distributed object model from Microsoft.

    Many of the network IP cameras that can be found on the market use the Netwave protocol, based on CGI commands to obtain video images through an internal http server. In this article I will show how to build a simple application to control these cameras, which are typically used for surveillance and can make scan motions in addition to providing video images.

    Axis is a Swedish brand, one of the world leaders in the video surveillance IP cams market, which has an extensive catalog of camera models that cover virtually any need. All its products have a common access protocol via HTTP, the VAPIX protocol, based on CGI commands, which makes it especially interesting to know.

    In this series of articles I will show a class library that implements a compiler that uses any language defined by BNF rules and that generates objects from a user-written class library, which must implement a simple interface so that the compiler can construct and initialize them from the source code.

    BNFUP is a class library that implements an object compiler from the definition of a language using BNF rules. It also provides rule editing services. In this article I continue showing how to use the editor to compile and test your own objects using the language you have defined for that. I will also show you three examples of implementation.

    In this article I will present a custom DataGridView control that allows using formulas composed by arithmetic expressions and references to the different cells of the control. In addition to the class library with the control, I have prepared a small application to show how to use the different features it offers.

    WCF (Windows Communication Foundation) is a framework for creating distributed applications whose components communicate with each other through services, using a wide range of network protocols. In this article I will comment on the fundamentals of creating and configuring one of these services through a data connector for the DBTextFinder application, a program to search for texts in a database that can be extended to connect to any data management system.

    The Tableaux is a logical calculus tool that is very useful to demonstrate a conclusion from a set of premises, find counterexamples or models of a set of logical formulas or demonstrate that a formula is a tautology, i.e., that is true in all possible cases. They can be used in artificial intelligence as the basis for implementing automated theorem proving.

    The Tableaux is a logical calculation tool that allows checking the validity of a conclusion from a series of premises. In the previous article I explained briefly the fundamentals of predicate logic Tableaux. In this article I will extend the program to the first-order logic, which has much more expressive capacity than predicate logic, although this makes also automatic calculation more difficult.

    There is a very common problem in linear programming which consists to find the values that make maximum or minimum the value of a linear function, given a number of restrictions on the values of their variables. For example, you may want to find a minimum cost or maximum production function. To do this, there is an algorithm developed in 1947 by George Dantzig, called Simplex, which allows perform such calculations in a simple and effective way.
