Uno de los componentes que más cambios y novedades trae en Windows Vista es IIS7, no solo cambio todo el modelo de programación de componentes, sino que la herramienta de administración es totalmente nueva, desde las betas de Vista y ahora con las betas de Longhorn Server he estado probándolo, pero nunca en una sitio en producción, así que decidí migrar el sitio web de mi compañía desde un servicio de hosting con IIS6 a un servidor propio con IIS7, la razón de este cambio está relacionado con una gadget que cree hace un tiempo , el mismo informaba la dirección IP publica de la PC que lo solicitaba, para ello leía la dirección desde una página que estaba alojada en mi sitio, todo funcionaba bien hasta que a fines de febrero mi proveedor de hosting me corto el servicio sin previo aviso por exceso de ancho de banda, yo bastante incrédulo fui a ver las estadísticas y tenia registrado 89 Gbytes de tráfico en menos de dos semanas, cuando mi plan solo me daba 20 Gbytes, luego de un intercambio Read More...

Chris Sells created the excusegenexpress project in Chapter 10 of his and Ian Griffith's book Programming Windows Presentation Foundation on a computer named EMULH. His user name is csells. Adam Nathan created the XBAP version of his PhotoGallery program in Chapter 7 of his book Windows Presentation Foundation Unleashed on a computer named NATHANKITCHEN. His user name is Adam. Is it weird that I should know this information? It's not exactly the type of stuff involved in fraud and identify theft, but it still seems rather personal. After all, I wouldn't want anybody to know that my computer's name is SLUDGEBOX and my user name is SweetThing. Why should that be public information? I learned about Chris and Adam's computer names and user names simply by opening these two projects from their books in Visual Studio, selecting Project Properties and clicking the Signing tab. Is it just a coincidence that the two Visual Studio projects in question are both XBAPs? No, it is not. In a previous Read More...

The story goes something like this: When Alfred Hitchcock was filming Vertigo he wanted to build a staircase structure that would expand in depth to simulate the acrophobia of the main character, played by James Stewart. But 2nd unit cameraman Irmin Roberts suggested it could be done with an optical effect. If a camera moves in on a subject, everything gets larger, of course, but the perspective also changes so that the distance between the foreground and the background seems to grow. If at the same time the camera zooms out at precisely the right pace, the foreground can remain the same size while the background seems to recede from the viewer. This combination dolly-in/zoom-out effect was used five times in Vertigo (released in 1958), each time accompanied by the same music: In the opening sequence (chapter 2 on the DVD), twice in the bell tower (chapter 20), and twice more at the end (chapter 33). Thereafter it was called the Vertigo effect or the dolly zoom or several other terms, and Read More...

Introduction (Note: This article is not strictly speaking for WPF only, the technique described works for any type of .NET application. In next articles, we'll study WPF-specific techniques, for example loading XAML resource assemblies dynamically.) There are many scenarios where an application doesn't know at build time exactly which DLLs are going to be available at runtime. For example, you may want to provide a UI framework and then develop components at a later time running in that framework. In .NET (WinForms or WPF), this is made possible by the following features: UserControls (or CustomControls) derive from a well known UI component (Control), which can be loaded in a panel. Assemblies can be loaded dynamically in the current AppDomain, using the methods Assembly.Load , Assembly.LoadFile , Assembly.LoadFrom . Note: there are differences between LoadFile and LoadFrom. See here for details. LoadFrom must be used with care, because the assembly's identity check is less strict than Read More...
