Random Walks For Windows Phone 7 - Jesse Liberty

jantu 1015 days, 5 hours, 43 minutes ago

It makes me a little crazy that every time the markets go up or down the newspapers cannot resist attributing a reason (though they’re not so good at predicting!). Today’s NY TimMarket Predictores: “Markets down 2% on concerns about slowing economy.” Oh Yeah? How do they know that’s the reason? Maybe it is the cost of oil, the situation in the middle east, unemployment, gamma waves… So I decided to try an experiment: let’s predict up or down randomly, and give reasons, and we’ll see how well we do.

Async Data Validation - Jesse Liberty

published 1024 days, 4 hours, 32 minutes ago posted by

jantu 1025 days, 4 hours, 57 minutes ago

In this posting I’ll extend the data validation mechanism we’ve been examining to support asynchronous data validation.Silverlight is all about client-side code, and client-side validation is often exactly what you want; however there are times that you do not want to expose your validation algorithm in the client or in which you need to do a dynamic database lookup (credit ratings come to mind). In that case, you’ll want your Silverlight application to be able to validate against a web service, but to ... (more)

Events and Delegates Under The Hood - Jesse Liberty

published 1038 days, 21 hours, 29 minutes ago posted by

jantu 1040 days, 6 hours, 4 minutes ago

Many programmers come to Silverlight with little prior experience with C#, and thus conceptualize events as a response to an action that is “hooked up” using somewhat arbitrary syntax. All of that is fine, until it isn’t, and so this post will dive a bit deeper into Delegates and Events as core aspects of .Net languages. (more)

Teaching An Old Control New Tricks With Templates - Jesse Liberty

published 1040 days, 5 hours, 48 minutes ago posted by

jantu 1041 days, 3 hours, 47 minutes ago

You will remember that in the previous post in this small series, we created a new button template with a new appearance and new behavior for the “standard” view states.This button will be used with our form, and the form in turn will (eventually) be prepopulated from a database. It would be very convenient if the button reflected the need for the data to be saved when the user updates any of the fields. The design calls for the button’s border to turn red when the user makes any changes, and to return ... (more)

Templates, Visual State and Fun With Controls - Jesse Liberty

This is the third (if you count Sunday’s update!) in my short series on Templates and Data Validation.ClickButton Today we’re going to create a templated Button that changes the appearance and visual state behavior of the button. Changing the visual state behavior in this case means responding to: * MouseOver, by swelling * MouseDown, by twisting and shrinking * Disable, by fading * Lost Focus and Get Focus (more)

Windows Phone 7: Lists, Page Animation and oData - Jesse Liberty

published 1084 days, 4 hours, 28 minutes ago posted by

jantu 1085 days, 3 hours, 6 minutes ago

This is the fourth in a fast paced series on programming Windows Phone 7. In this mini-tutorial I will demonstrate how absurdly easy it is to create a master page with a list of data, and a details page to display more information about the selected item, and to animate the transition from one to the other. To make it more interesting, we’ll get the list and the details from a web service, using oData.The reason all of this is so easy is that Visual Studio 2010 provides a template for this very case.

You Already Are A Windows Phone 7 Programmer - Jesse Liberty

John Papa invited me on to Silverlight TV to discuss a key premise of WP7: Silverlight Programmers are instant WP7 programmers. To demonstrate this, I created two applications side by side: a traditional Silverlight (Web) application and a WP7 application using the same code.I’ll go through this step by step here, so that you can see the details that went by a bit quickly in the video. I’ll also bring the two programs into even closer alignment… (more)

Screen Scraping – When All You Have Is A Hammer - Jesse Liberty

published 1115 days, 6 hours, 23 minutes ago posted by

jantu 1116 days, 8 hours, 6 minutes ago

I had decided to create a list of what videos were already available on the Learning Pages of Silverlight.net. When I clicked on the page for the entire list, however, I was quite daunted by the sheer number. I opened the “source” for the page, and found that there was an easy screen scraping capability, however. The name of each video was also a link to its landing page, and so I could grab the HTML and search for the appropriate links. (more)

The Silverlight HyperVideo Player has met with strong support and interest. This mini-tutorial is the first in a series that will walk through the design and delivery of this project.This series will pretend that the design existed before we began coding, and will not take you through its evolution over the months between December 2009 and March 2010. In short, this series is a “drop-line” exercise highlighting how the program works with a focus on teasing ou... (more)

One of the goals of the Silverlight HyperVideo Project is to demonstrate best practices. So when is it okay to throw in a quick hack to get things working?Case in point: as I approached the release this week for the latest alpha, I noted that the player was not updating when the user clicked on a topic, though the links were appearing as if the player had been advanced.To make the issue clear, in this image you s...

I often receive questions about topics covered in one or another of my books, and I respond, most often, privately. Every once in a while, however, a question comes along that may be of more general interest. This question, though about C#, has a profound effect on Silverlight programming as well…When you want to abstract out what is required from how ... (more)

Configuration & Decoupled Modules - Jesse Liberty

jantu 1216 days, 5 hours, 9 minutes ago

Two architectural demands for the Silverlight HVP, which are common to many larger applications, came together this week and crystallized into a design that looks to solve a couple other, unanticipated requirements. Specifically, we knew that (1) we wanted to have configuration files and that (2) we wanted each module to be created independently of all the other modules. After some discussion, thrashing, input from some great folks at CodeMash, and further review,... (more)
