bueno, tratare de ir posteando lo k vaya aprendiendo en este lenguaje
les dejo un poco de teoria
“Muchos dicen que si Java se puede considerar un C++ mejorado en cuestiones de seguridad y portabilidad, C# debe entenderse como un Java mejorado en todos los sentidos: desde la eficiencia hasta la facilidad de integración con aplicaciones tan habituales como Microsoft Office o Corel Draw."
Las frases del inge pollis en facebook!
Bueno por algo se empieza y en esta ocasión les presento mi aplicacion en Facebook, es algo sencillo. Pero esta muy divertido..
Google festeja hoy sus 11 años Online (¿de vida?)
El 27 de septiembre parece haber sido la fecha elegida por la empresa que hoy mismo cambia su logopara celebrarlo, aunque muchas personas discrepan y consideran que el nacimiento de Google tuvo lugar el día 15 del mismo mes
[caption id="" align="alignnone" width="600" caption="11 años de google"]
[/caption]Hoy Google celebra su cumpleaños número 11 y para celebrarlo agregó una letra L extra: Googlle (Goog11e).
El aniversario de Google se celebra durante el mes de septiembre, no tiene una fecha exacta, aunque en2002 y 2005 (y ahora 2009) se escogió el día 27 de septiembre para celebrarlo desde el logo del buscador.
Con once primaveras a sus espaldas y convertidos en la mayor empresa de internet, Google nos regala, semana a semana, todas las novedades para hacer más sencilla nuestra navegación por la red.
Según figura en los archivos, fue fundada el 7 de septiembre de 1998 por Larry Page y Sergey Brin(dos estudiantes de doctorado en Ciencias de la Computación de la Universidad de Stanford).
Aunque su principal producto es el buscador, la empresa ofrece también entre otros servicios: un comparador de precios llamado Google Product Search (antes conocido como "Froogle"), un motor de búsqueda para material almacenado en discos locales (Google Desktop Search), y el servicio de correo electrónico llamado Gmail, el cual pone a disposición para sus usuarios más de 7 GB[2] de espacio.
También es famoso su programa Google Earth, un mapamundi en 3D con imágenes de alta resolución. Recientemente lanzó su versión beta de un servicio de mensajería instantánea basado en Jabber/XMPP llamado Google Talk.
Encontrar el valor de un Window Message
De vez en cuando, si trabajamos con WinForms, nos puede surgir la necesidad de manejar un evento a muy bajo nivel y para hacerlo tenemos que interceptar los famosos Window Messages, o mensajes de ventana. Estos mensajes son el mecanismo que utiliza Windows para comunicarse con una aplicación. Cuando apretamos una tecla y nuestra aplicación responde, parece que es nuestra aplicación la que ‘atrapó’ el teclazo, pero en realidad es el Sistema Operativo (SO) el que lo atrapó (debido a que el SO es quien controla el puerto donde esta conectado el teclado) y este le envía un mensaje a nuestra aplicación para que responda al mismo, normalmente imprimiendo el caracter representado por la tecla presionada. Aunque no lo parezca, el SO es quien tiene control de todo lo que sucede y cuando nuestra aplicación responde a distintos inputs, es en realidad el SO el que le ordena que haga una cosa u otra.
Si tenemos un Form y el SO determina que es necesario que sea redibujado (porque cambio su contenido por ejemplo), entonces se envía un mensaje conocido como WM_PAINT (en .NET veremos que esto dispara el evento Paint), en cambio si presionamos la tecla ‘Q’ en el teclado, entonces el mensaje recibido por nuestra aplicación es WM_KEYDOWN (también tenemos el evento KeyDown en .NET, el cual es lanzado cuando se recibe un mensaje de este tipo). Cabe aclarar que el nombre de los mensajes es solo una ayuda para nosotros los humanos, ya que los mensajes en realidad no son más que un valor entero, y estos nombres son los nombres de las constantes asociadas a los mismos.
Para interceptar estos mensajes lo que se suele hacer comúnmente es sobrescribir el métodoWndProc definido en la clase Control de la siguiente manera:
1: ...2: private const int WM_PAINT = 15;
3:4: protected override void WndProc(ref Message m) {
5:6: if (m.Msg == WM_PAINT) {
7: // Atrapamos el mensaje...
8: } else{
9: // Ignoramos el mensaje y dejamos que siga su curso
10: base.WndProc(ref m);
11: } 12: 13: } 14: ...El método WndProc es el que se encarga de procesar todos los mensajes que recibe un Form y es por eso que ese es el punto indicado para atraparlos.
Ahora el problema esta en conocer el valor de los mensajes, ya que muchas veces uno sabe que mensaje procesar, pero no sabe cual es su valor. Estos valores están definidos en la claseSystem.Windows.Forms.NativeMethods y System.Design.NativeMethods, pero lamentablemente estas clases son internas y no tenemos acceso a ellas, por lo que vamos a tener que usar .NET Reflector para ver su contenido.

MonoDevelop 2.2 Beta 1: We go cross platform.
MonoDevelop goes cross platform.
Since the beginning of time, man has yearned to get a cross platform .NET IDE. Homer's Odyssey described one man's effort to achieve such a thing. And it was not until today, September 9th of 2009 that the world can test out such a tool.
With this release MonoDevelop leaves its cozy Linux nest and embarks on a wild adventure into the hearth of MacOS and Windows. The MonoDevelop team made this one of their major goals for this release: to turn our loved IDE into a cross platform IDE.
If you are curious about the details, check out the What is new in MonoDevelop 2.2 page.
MonoDevelop on Windows
We are not only bringing MonoDevelop to OSX and Windows as a plain GUI port, but we are also providing installers, deep operating system integration and support for native debugging on each platform.
MonoDevelop on MacOS X
In addition to becoming a cross platform IDE, there are many new features in MonoDevelop.
For instance, MonoDevelop can be used to develop ASP.NET MVC applications on OSX and Linux and Silverlight applications on OSX and Linux.
MonoDevelop now has integrated debugger support. Not only it is able to debug Mono applications, it also can work as a frontend to GDB to debug native applications.
In addition, on Linux it is possible to debug ASP.NET pages.
New exciting add-ins: ASP.NET MVC, Silverlight and iPhone (for use with MonoTouch).
A common problem that we face as open source developers is that not every project uses the same coding style. Different teams use different coding conventions. MonoDevelop now supports policies to describe how files should be edited and what defaults should be used in each:
My favorite new feature is Dynamic Abbrev (Alt-/) a feature that we brought from Emacs and that fills me with joy. That being said, for the non-Emacs lovers there are plenty of features that you asked for, and that we implemented:
Another pretty cool feature is the code generation support that is triggered with Alt-Insert. When you press Alt-insert it will popup a context sensitive dialog box that offers a few options of code that could be generated at this point: ToString methods, Equals/GetHashCode methods all based on existing fields and properties.
Going cross platform means that developers will have the same tool across all of the operating systems they use: Windows, Mac and Linux.
.NET developers that have been enchanted by OSX will be able to continue developing software with their favorite programming languages while enjoying OSX and will be able to go back and forth between Windows, OSX and Linux as needed. This also means that they can work with developers in other platforms, regardless of the personal choices of other team members.
As many of you know, the number of contributors to a project is linked to the number of users of that project. By expanding our market presence from Linux, we expect to get contributions, fixes, improvements, bug reports, code and add-ins from developers in other platforms.
We intend to make MonoDevelop the Eclipse of the .NET community. Just like Eclipse became the foundation for Java development, we hope that MonoDevelop will become the foundation for .NET development, and hopefully for much more than that.
We are not religious when it comes to supporting other programming languages [1]. We want to embrace not only .NET-based projects like Gtk#, Silverlight, ASP.NET, Boo, C#, F#, Visual Basic and Windows.Forms. We are also embracing other developer platforms like Python, C/C++, Vala, and we want to expand our presence to work with the Flash, PHP, Ruby, Rails, Flex and any other communities that need a cross platform IDE.
[1] we are just religious about the fact that C# is a better programming language to build an IDE than Java is.
This release could not have been possible without the endless nights and the collaborations of our contributors and all of the end users that reported bugs and gave us feedback.

Policies
A common problem that we face as open source developers is that not every project uses the same coding style. Different teams use different coding conventions. MonoDevelop now supports policies to describe how files should be edited and what defaults should be used in each:
Editor Improvements
My favorite new feature is Dynamic Abbrev (Alt-/) a feature that we brought from Emacs and that fills me with joy. That being said, for the non-Emacs lovers there are plenty of features that you asked for, and that we implemented:
- Extensive refactoring support. And I mean, it is extensive.
- Code templates.
- On the fly formatting.
- Acronym Matching in Code Completion
- XML Documentation Shown in Code Completion
- VI mode for those users hooked up on VI commands, they can now use those within MonoDevelop.
Another pretty cool feature is the code generation support that is triggered with Alt-Insert. When you press Alt-insert it will popup a context sensitive dialog box that offers a few options of code that could be generated at this point: ToString methods, Equals/GetHashCode methods all based on existing fields and properties.
Why go Cross Platform?
Going cross platform means that developers will have the same tool across all of the operating systems they use: Windows, Mac and Linux.
.NET developers that have been enchanted by OSX will be able to continue developing software with their favorite programming languages while enjoying OSX and will be able to go back and forth between Windows, OSX and Linux as needed.

A multi-system IDE
We are not religious when it comes to supporting other programming languages [1]. We want to embrace not only .NET-based projects like Gtk#, Silverlight, ASP.NET, Boo, C#, F#, Visual Basic and Windows.Forms. We are also embracing other developer platforms like Python, C/C++, Vala, and we want to expand our presence to work with the Flash, PHP, Ruby, Rails, Flex and any other communities that need a cross platform IDE.

Visita A La Universidad Tecnologica De Gutierrez Zamora
El dia de hoy muy temprano sali para la ciudad de Gtz. Zamora, el asunto una invitacion del ISC. Luis Rizo, para una entrevista, la estancia fue de los mas impresionante el viaje aunque un poco cansado me deja un buen sabor de boca dado que en esta escuela aunque sus ofertas educativas son: - -, tienen mucha vision sobre el sw libre y la aplicacion a casos reales con ellos, me siento muy contento de haber asistido y desde aca, les mando un cordial saludo muchisimas, gracias..
