  In the latest installment of Pluralsight’s Meet the Author podcast series, Fritz Onion and I talk about my new course, HTML5 Canvas Fundamentals.  In the interview I describe different canvas technologies covered throughout the course and a sample application at the end of the course that covers how to build a custom business chart from start to finish.

When is a cast not a cast?

AddThis Social Bookmark Button
I'm asked a lot of questions about conversion logic in C#, which is not that surprising. Conversions are common, and the rules are pretty complicated. Here's some code I was asked about recently; I've stripped it down to its essence for clarity: class C {}
class D
  public static C M(C c)
    return something;
public static class X
  public static V Cast(object obj) { return (V)obj; }
} where there are three possible texts for "something": Version 1: (C)c
Version 2: X.Cast>(c);
Version 3: (C)(object)c Version 1 fails at compile time. Versions 2 and 3 succeed at compile time, and then fail
at runtime if U is not bool. Question: Why does the first version fail at compile time? Because the compiler knows that the only way this conversion could possibly succeed is if U is bool, but U can be anything! The compiler assumes that most of the time U is not going to be constructed with bool, and therefore this code is almost certainly an error, and the compiler is bringing that fact to your attention. Question: Then why does the second version succeed at compile time? Because the compiler has no idea that a method named X.Cast...(Read whole news on source site)

Q&A #18 – NaN for a Windows Phone Textbox Height

AddThis Social Bookmark Button
NaN for a Windows Phone Textbox Height Did you know that you can set the value of the height property to “NaN” for a Windows Phone textbox? The Textbox height property accepts double value but can also accept “NaN”. By specifying this, we can specify the auto size property for the textbox. Alternatively, you can also set this value to “Auto” too.

Pragmatic Tips for Building Better Windows Phone Apps

source: MSDN Magazine I love building apps for Windows Phone. I love creating code samples and writing about the Windows Phone platform as part of my day job, though I've had my ups and downs along the way. Throughout all of this work I've stumbled and picked myself up, and dug myself into holes, but climbed back out. What I want to do is smooth out this obstacle course for you with some pointers in this article. I'll talk about controls, User Datagram Protocol (UDP) Multicast, the Ad Control, isolated storage, tools and 256MB devices. So sit back,
relax and enjoy. Specify the TargetName when Using a HyperlinkButton The HyperlinkButton control is a button control that displays a hyperlink. I use this all the time to help the user navigate my app, or the Web. In one of my apps I was using a HyperlinkButton to show some help information, and I wanted a hyperlink to take the user to more information on the Web. So I did the following (details omitted): Help Simple, right? I ran my app, navigated to the page containing my little help button and clicked on the...(Read whole news on source site)

"Access Denied" Error when Creating Publishing Subsites

AddThis Social Bookmark Button
This is a very specific error I ran across, but I only saw two postings online where others encountered this same problem, so I thought I'd post my resolution in case someone else runs into the same problem. The Scenario In my server environment, I have two special SharePoint groups, based on requirements by the IT department. 1. The "Manage" Permission set includes all the Permission checkboxes except for two checkboxes related to seeing user permissions and creating groups. Instead of adding users to the "Site Owners" group, that has the "Full Control" permission set, our site owners are called "Managers" and have
been granted this permission set. The key thing to note is that these users do have the permission to create subsites. 2. Instead of using the "Resitricted Readers" group, a new group was created (which followed specific naming conventions) and given the "Restricted Read" permission set. The Problem After doing this, when a "manager" tried to create a new publishing site inside the site collection, they got the following error: "Provisioning did not succeed. Details: Failed to initialize some site properties for the Web at Url: '[my url here]' OriginalException: Access is denied (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
