SharePoint Developer Tools in Visual Studio 11 Beta – Part III: Tips and Tricks in SharePoint List Designer

AddThis Social Bookmark Button
In the Part I of this series, we were pleased to announce the SharePoint List Designer as one of the new features introduced in Visual Studio 11 Beta. Using the List Designer, you can quickly and visually build a SharePoint list within Visual Studio without having to create a list first in SharePoint Designer and then import it into Visual Studio. To familiarize you with the List Designer, in Part I of this series, we provided a link to a MSDN Help topic that walks you through the process of creating a list and a content
type by using the List Designer. If you’ve used the List Designer, you might want more details about its functionality. This blog post provides more information about it.   A Closer Look at the SharePoint List Designer Pages and the Files behind Them You may have already seen that when you add a new list item to a SharePoint project, a visual designer opens with three tabs: Columns, Views, and List. Figure 1: SharePoint List Designer pages Also, in Solution Explorer, a List node is created, consisting of two files (Schema.xml...(Read whole news on source site)

QR codes for Asp.Net with NuGet

AddThis Social Bookmark Button
About a week ago, I received an email from a visitor about my QR code post which I blogged about back in 2010. I have been told that the most important reference was down. It was the reference to the DLL for generating the QR codes. So I uploaded the DLL as mirror Apparently the twitt88.com website is back online at http://platform.twit88.com/projects/mt-qrcode/files It also seems that there has been some new releases for the DLL. Since 2011 you only use NuGet to keep your packages up to
date, I thought that adding it through NuGet would be the best option. Searching for ‘QR’ did not return any good packages. Searching for ‘QRcode’ did. It returned one package for MVC https://nuget.org/packages?q=qrcode But I still have WebForms in this solution… Investigating the source of that package, pointed me to this open source QR project from codeproject. But that is an article from twitt88 from 2007! So the only QR code package in NuGet references (really) old material from the exact same user! That’s when I decided to help out the community...(Read whole news on source site)

null is not false, part three

Returning now to the subject at hand: we would like to allow user-defined "overloads" of the & and | operators in C#, and if we are going to have & and | be overloadable, it seems desirable to have && and || be overloadable too. But now we have a big design problem. We typically overload operators by making a method: class C
{
  string s;
  public C(string s) { this.s = s; }
  public override string ToString() { return s; }
  public static C operator +(C x, C y) { return new C(x.s + "+" + y.s); }
}
...
Console.WriteLine(new
C("123") + new C("456")); // "123+456" But method arguments are eagerly evaluated in C#. We can't very well say: public static C operator &&(C x, C y)  { ... whatever ... } because when you cay C c = GetFirstC() && GetSecondC(); that is going to be rewritten as something like: C c = C.op_ShortCircuitAnd(GetFirstC(), GetSecondC()); which obviously evaluates both operands regardless of whether the left hand is "true" or "false". Of course in modern-day C# we have a type which represents "perform this calculation that produces a result in the future, on demand"; that type is Func....(Read whole news on source site)

Updated version of "TrueSkill Through Time" Bayesian Inference Code

AddThis Social Bookmark Button
Back in 2007 Ralf Herbrich and co. wrote a research paper called "TrueSkill Through Time". Their sample code was written with a pre-release of F# 1.0, and was not updated to F# in Visual Studio 2010. Here is an update of this code for F# in Visual Studio 2010, as requested by some people commenting on that blog entry. Please note that I'm not an expert in the code, and that it does currently require a database connection to use (to save the analysis results)

Microsoft Press Deal of the Day - 19/Apr/2012 - CLR via C#, 3rd Edition

AddThis Social Bookmark Button
Today's Microsoft Deal of the Day at http://shop.oreilly.com/product/9780735627048.do is CLR via C# price $23.99
I have read CLR via C# ISBN 978-0-7356-2704-8. Whilst it is quite correctly described by the publisher as a "Deep Dive", this is a book that C# developers with 6-18 months plus experience ought to read. Certainly any serious Microsoft programming shop ought to have a copy.  Even our experienced VB.NET brethren will benefit from reading this book. When I started programming 31 years ago I went through IBM 360 Orientation - this gave me an comprehension of what worked best at
the machine code level - this is the first book I have found that explains the the working of the Dot Net framework to explain why particular choices are good.
